This is something that can be repaired without the risk of replacing the entire window.

This. One of those kits to paint on defroster wire traces for the back window. Resurected an apple keyboard from 2005 period that was half filed with coke. Basically repainted the left 1/4th of the entire membrane with a little vile from advance auto.

12V/5V is nothing for a off the shelf switch. If you want to get semi-fancy, you can take one of our 5 1/2 in bay covers and drill out the appropriate sized whole and install 4 toggle switches. Maybe 5 if you want a master kill switch (space permitting).

Here is a 5-pack for $10: https://www.amazon.com/Nilight-Rocker-Toggle-Switch-Waterproof/dp/B078KBC5VH/

Get some PWM fan header cables (https://www.amazon.com/CRJ-Black-Sleeved-Splitter-Adapter/dp/B075H6HT8J/ for instance). you just need enough extra cable to go from the PWM header on the Mobo to the switch. Make sure the PWM lead (yellow i think?) and Negative is still wired to the fan. You still would like to monitor the RPM I am sure. Simply wire each 12V+ lead to the switches.

Even better, get some switches with an LED so that you can tell when they are on: https://www.amazon.com/Lighted-Rocker-Toggle-Linkstyle-Vehicles/dp/B0776QXX21


Edit: Cant confirm this... But this doc seems to show some or all of the PWM specification if you want to dig further. https://www.handsontec.com/pdf_files/4_Wire_PWM_Spec.pdf

OK. Here is what you are dealing with:

1.(L) black. Line voltage load. Either 110v or 220v. Need to verify with a voltmeter.

2.(W/Y) orange. W=heating and Y=cooling. Used for a two pipe hydronic heating/cooling system. That means water.

3.(Y/A) yellow. Y = cooling. A = electrical heater output. Heat and cool active to any relay.

4.(G1) red. Low speed fan. Through a relay.

5.(GM) blue. Medium speed fan. Through a relay.

6.(GH) brown. High speed fan. Through a relay.

7.(N) white. Line voltage neutral. Either 110v or 220v. Need to verify with a voltmeter.

What is missing is the "C" and "R" wires. Nowhere is there a low voltage 24v load and common wire. Your current thermostat does not use it.

You have two options that I know of. Purchase a transformer to supply the 24v to your new thermostat. Or return the Honeywell and purchase a wifi enabled line voltage T-stat.

Transformers. Here are two that may work:

Note: Since you have hydronic heating and cooling, in addition to HVAC, either choice for the thermostat will likely mean that you will loose that option. I have not evaluated the new Honeywell or Casa to see if they support hybrid systems.

u/bittabet · 5 pointsr/RealTesla

No I've had multiple cars where the lines are obviously on the inside surface. They sell repair kits for rear window defrosters and obviously none of these kits would make sense if it was inside the glass.

That said, some higher end cars do integrate the lines into the glass these days but it's a mixed bag. You're less likely to have someone damage the lines by accident and thus less likely to need a repair, but if the lines do go bad over time you have to replace the damned rear glass (and they do go bad). Not sure which I'd rather deal with lol

u/GuinnessDraught · 5 pointsr/shutupandtakemymoney

I don't know about the Avalon specifically, but its possible in many cars. You'll have to exercise some Google-fu.

A whole bunch of factory head units, especially on nicer cars starting in the early 2000s, have aux inputs on the back of the unit. Before an aux input became a standard equipment expectation, it was often a dealer-installed option (i.e. plugging in and running an aux cable) or used to wire up a CD changer (which you can often unwire and replace with an aux in).

For instance, here's what I installed in my car: http://www.amazon.com/BMW-82-11-149-389/dp/B000PA00XM#productDetails. $36 on Amazon for OEM, or you can hunt around on eBay or other smaller sites and probably find an OEM one for $25 or a knock off for $15. Literally just plugs into the back of the unit, then you run it to wherever you want, but typically the glovebox is easiest.

Optionally, I also discretely mounted a small ~$40 bluetooth/A2DP receiver (this guy, much nicer than OP, gets power from the car and also doubles as a USB power plug) on the dash next to the stereo and ran its wire under the trim into the glovebox to connect to the 3.5mm aux. It works/sounds great and I mostly use the bluetooth since its nice to not have to fiddle with wires every time I get in/out of the car, but I can also unplug the bluetooth and plug straight in to the 3.5mm plug in the glovebox.

u/Alaeron · 5 pointsr/starcitizen

After seeing a couple posts of people's custom button boxes on reddit I knew I had found my next project. I've been doing quite a bit of Arduino and small electronics lately, and this was the perfect fit. So off I went to Amazon, ordered a bunch of stuff I thought might be cool / useful and started piecing things together. Took a few weekends of working on it here and there, the most time consuming part just being tediously soldering and wiring the 38 inputs.

​

Was originally going to set it into some sort of project enclosure, but ended up getting impatient and just mounting it to two pieces of plywood with some feet. It added enough heft to it that I can lift the switch guard and rotate the somewhat stiff selector without issue. Eventually I'll get a better enclosure for it, probably grab one off of Hammond mfg or get someone with a larger 3D printer to make one. The Engine Start and black/red button (that I'm going to use for quantum jump) have leds in them that I don't currently have hooked up to the Arduino, but once we get some sort of API into Star Citizen hopefully I can tie them to engine state and jump spool/ready state.

​

The controls are:

Power on, flight ready, 3 misc buttons, zoom rotary encoder, 3 misc buttons, quantum spool, quantum jump

Hat switch + center for shield distribution and reset, engine, shield, and thruster power switches, power distribution profile selector, misc selector

Flare Fire button, flare select, 7 misc toggle switches, self destruct switch, eject switch.

​

I mapped everything to a button in the Arduino code (no rotary encoder as zoom in this screenshot) so that I can easily bind to functions in Star Citizen. Unfortunately without an API this means the switch positions can get out of sync with the actual ship status easily. If by the time of release / they make an API there still isn't a way to read / set state by API then I'll probably make a new version with only toggle buttons.

u/emnc91 · 3 pointsr/arduino

I would think it's best to power the motors with a separate power supply from the Arduino power since the motors will draw a lot of current. Instead of powering the motors from the onboard 5v supply, run a separate supply through either a relay module or a motor controller board. Like these: relay, motor driver.

u/Terriblis_Pater · 2 pointsr/Charger

It’s just an electrical connection. You’re basically going to bypass the +12v wire that activates the valve flaps from the control module with a +12v wire that is activated by an accessory source(think cigarette adapter, radio, etc.).

What I would do is use one of these:
https://www.amazon.com/AutoEC-Rocker-Toggle-Switch-Control/dp/B012IJ35VQ/ref=mp_s_a_1_6?keywords=12+volt+power+rocker+switch&qid=1566944665&s=gateway&sr=8-6

That way you can have it “always on” until you flip it into the other position, and have it managed by the control module. Essentially one of the connectors will go to the flap, the second one will be the +12v from the original source, and the third wire will be the +12v from a cigarette adapter (which should only be “on” when the ignition is on). It’s a bit more complicated than that since you’ll have to worry about heat shielding the wires, where they come into the cabin, and where you put the switch. You may have to remove some molding/trim/carpet but it shouldn’t be much harder than wiring up an aftermarket amp/sub.

u/Sophias_dad · 2 pointsr/MechanicAdvice

It should be possible to fix that loop with defogger repair. I've had good luck with this one, but I'm sure there are others that would do the same. Try to keep the same width of line, especially since its not really carrying any current. The alarm may notice the anomaly in the trace anyway, but its worth a try, to save £435

Nice work!

Looks like that mount could support a pretty hefty tarheel/screwdriver type antenna. Any reason you chose to to make a hinge mount over using a bracket that bolts to the spare tire carrier? Like this

u/RichardBLine · 2 pointsr/HomeKit

As long as the circuit is closed, does it matter how it got closed? Meaning, you can use any I/O module to complete the circuit and then hook up a Homekit switch to trigger the I/O module to close the circuit.

For instance, if you used something like this and connect one end to your fireplace (and I'm just using this module as an example as I don't know if it is compatible with your fireplace): https://www.amazon.com/Enclosed-AC-Protection-Bounce-Terminals/dp/B017743I7S/
and the other end to a Homekit switch or outlet. That should work, should it not ?

u/[deleted] · 2 pointsr/AskReddit

If you want to skip all of the good, rational advice, I'm here to offer you a way to get him out of your life as quickly as possible.

  1. Find an old webcam and take out the infrared filter. Tutorial
  2. Find a tv remote and tape one of the buttons down to where he should be standing at night (if this is not bright enough you can buy an illuminator here
  3. Install this video surveillance software.
  4. If for some reason your webcam has a light on it, just duct tape over the light.
  5. Just run it every night and wait for him to do it again.
  6. Once you have the proof, take it to the police, take it to your mother, your grandparents, your dad, a school councilor, anyone you can trust. (Just be sure to back up the video online via a password protected online hosting service, or put it on a flash drive or CD and hide it somewhere)

    People will lie, do anything to cover this up, he will do anything, defame your character, adults are much better at manipulating people than you will be most likely, and people will be more likely to believe them. With video proof though, their lies become meaningless, no matter what the situation. You need something like this to back up your story depending on your situation. This might not be necessary, but it's here for you you need it.

    To be more effective, I would recommend only launching this plan before doing anything else to try to stop the behavior. This could easily escalate into sexual abuse.

    Oh, and if you want a hilariously simple solution that would probably stop the problem all together. Install a loud digital ringer on your door from the inside that chimes when you open the door, and turn it on at night. Every time your door is opened it will ring, and scare him away. He also won't be able to turn if off without making it ring.
u/btcnoodle · 2 pointsr/Bitcoin

After considering our discussion on this I can tell you for sure what I would do if I were in your situation. Since you already have a solar system in place and not starting from scratch you will need a DC-DC switching power supply to replace the AC inverter. I still have never seen one for sale that is suitable for mining so I would build my own to run a single ant s9 based on the design I have tested extensively running 2 ant s5. The design to run 2 s5 is pulling about 700 watts so we need to scale that up to do about 1400 watts. To get right to it these are the parts you'll need, I'll explain in a bit how it will need to be put together and how I came to this design in the first place. After I get all that out I will try to answer some of the other questions folks have about a fully stand alone system. For your needs you will only need the DC power supply/switch/regulator.

2 of these (note it's a 5 pack so you'll be getting 10 relays total. 8 will be used) about $28
https://www.amazon.com/Pack-EPAuto-Relay-Harness-Bosch/dp/B017VDI0GY/ref=sr_1_1?ie=UTF8&qid=1468169603&sr=8-1-spons&keywords=12v+relay&psc=1

1 of these about $70
https://www.amazon.com/Tracer-Tracer1210RN-Charge-Controller-Regulator/dp/B008KWPGS6/ref=sr_1_5?ie=UTF8&qid=1468170133&sr=8-5&keywords=mppt+charge+controller

10 of these about $200
https://www.amazon.com/Nextrox-Converter-Regulator-Step-Down/dp/B00BWKXTUU/ref=sr_1_11?ie=UTF8&qid=1468169653&sr=8-11&keywords=12v+voltage+regulator

Those three items are an mppt charge controller that will be used to control the relays. The 12v relays which will allow you to safely control the power switching and voltage regulators to make sure the power stays clean so as not to damage your gear.

Here's how it goes together, note that all regulators and relays will be hooked in parallel to allow us to get to the desired total amperage;

  • DC 12 volt power bus (battery main) gets hooked to the charge controller, powering it up in the 12v range.
  • Negative bus lead connects to the regulator negative.
    -Positive bus lead connects to relay pass in
  • Relay pass out 12v positive lead connects to regulator positive.
  • Relay 'activate power' leads get connected to 'lamp controller' on charge controller.
  • Regulator positive and negative out connect to miner power cables (pci-e)

    Once this is connected as such pressing the orange button on the charge controller front panel will activate the relays allowing power to flow to the regulators which will then even it out and pass it to a secondary bus which will then have the miner power cables hooked to it and power the miners.

    By using the lamp controller feature of the charge controller you get low voltage protection. If the batteries get low (even though sounds like you won't have much of a problem with that) the lamp controller will power down the relays and therefore stop the miners. It will automatically reconnect when the battery charge comes back up to safe level.

    The idea is to have all this in a box with cooling fans (12v dc case fans) and size it to power a single miner. This box of parts gives you about a 15% efficiency boost over using a big inverter. The cost of an inverter to do this is about $2000, my solution costs about $300, thus dramatically reducing total system costs and allowing a modular approach that will scale while limiting down time due to equipment failure.
u/ViceConviction · 2 pointsr/BMW

Personally, I would just go for the aux. Save yourself a ton of money, and don't worry about the bluetooth pairing. If you're dead set on bluetooth I apologize for not helping in that field. I don't know much pertaining to it.

u/gtg465x2 · 2 pointsr/Hue

I have a gas fireplace that was controlled by a switch on the wall. The switch was a low voltage switch that essentially just connected two wires together to turn on the fireplace and disconnected them to turn off the fireplace. The electronics that control the fireplace are behind a panel underneath the fireplace, and there is a decent amount of room and a power strip in there. I believe most gas fireplaces controlled by a switch on the wall have a similar setup.

So what I did was plugged in a Lutron Lamp smart plug (https://www.amazon.com/Lutron-Wireless-Lighting-PD-3PCL-WH-Assistant/dp/B00KHSXB60/ref=mp_s_a_1_3?keywords=lutron+lamp+dimmer&qid=1564055576&s=gateway&sprefix=lutron+lamp+&sr=8-3) to the power strip below the fireplace, and then I plugged in this AC/DC relay to that (https://www.amazon.com/gp/aw/d/B017743I7S?psc=1&ref=ppx_pop_mob_b_asin_title). What the relay does is just make a connection between its terminals whenever the outlet it’s plugged into (the Lutron Lamp plug in this case) is turned on. I then spliced the wires going to the switch on the wall and connected them to the relay. Then, the last step was to pair a Lutron Pico remote / switch (https://www.amazon.com/gp/aw/d/B00KLAXOE8?psc=1&ref=ppx_pop_mob_b_asin_title) to the Lutron lamp plug, and then I replaced the switch on the wall with the Lutron Pico switch. Now I can turn the fireplace off and on from a switch on the wall still, but I can also control the fireplace from HomeKit, Google Home, Alexa, etc. I also set up some rules to automatically turn off the fireplace if it’s been on for 3 hours, and to notify me if it turns on and I’m not home. These are just in case we accidentally hit the button to turn it on while we’re in bed or away or whatever.

u/L8sho · 2 pointsr/golfcarts

I just put lights on my drive.

I used this on the front and this on the rear.

Since the motorcycle taillight has a circuit for both the tail light and brake light, I wired the tail light to the same switch as the head light. I bought an adjustable motorcycle led flasher and put the brake light on a second circuit and switch.

So, I ended up with a headlight/taillight combo on one switch, and a brighter, flashing taillight on the other switch. Both of these circuits are only active when the key is turned on. I am quite pleased with the outcome.

While I was in the dash, I also added a 12 volt power port for charging phones and my bluetooth speaker, which has a mount on the dash.

FYI, there is a factory power harness which has unused 12 volt power located behind the key switch.

I'll try to post pics when my phone is charged.

Feel free to ask any questions. I'm pretty familiar with the electrical on the drive now (mine is gas).

Edit: Here are some pics. Excuse the dirty cart. Believe it or not, that little cheapo light bar actually put out too much light. At first, it would light up a stop sign 150 yards down my street. I aimed it at the ground to keep from blinding oncoming traffic.


u/computiNATEor · 2 pointsr/cars

How to tell if you have DSP. You will need the BM53 radio to add auxiliary to have Bluetooth streaming. Buy used on eBay. For non-nav vehicles, the radio is located in the dash (with the amp in the trunk), beneath the little flip-up panel and behind the MID. It's pretty simple to upgrade. BMW sells an auxiliary input retrofit kit for the BM53 radio. Pair that with an aux->Bluetooth device that you can keep in the glovebox.

Having this on your wall for your garbage disposal would be amazing!

u/amanita_miner · 2 pointsr/raspberryDIY

Most simple relays I've used have 3 connections, allowing 2 choices - either NC or NO. Just wire it for what you need.
I can't help with ordering to CA - but this is one where you can see in the pic that you can wire it either way.

After seeing what /u/SgtDwightSchrute1 built the other day, I wanted to give it a go as well! I took most of the parts he used and linked in his thread, but I went with a few more switches as well as a set of POV buttons that have a mode switch to switch them from POV directions to an X-Y axis. The Green button is for the POV mode, and I also moved the Mode LED to the face of the box so you can tell what mode it is in.

I also added some vinyl carbon fiber wrap to give it a nice finish!

Step 1. If it is the cheapie electric baseboard heat, you most likely have a 120v or 240v thermostat. Find out which.

I recommend those as cosmetic upgrades, as well as white LED lights for the visor, dome, and license plate. It's incredibly simple to replace and in my opinion it makes it look much better.

A more expensive (but worth it) would be a gloss black vinyl roof wrap.

I used a reed switch connected to a GPIO port to detect if the door is open. I used Twilio to send me an SMS. I used a relay board (like this one) in parallel with the manual pushbutton to toggle the door. And I used Python to serve the site. Let me know if you have specific questions.

Ok well nice job deleting as much as you can it's very necessary on these bikes. Do you have a manual? I ha e a copy of a minimal wiring diagram I used on mine I can forward to you so you can trace your own wiring. Have you tested the LEDs? Most of these old bikes can't read a signal that small and need a relay (ex:AUDEW 2-Pin Electronic Turn Signal Flasher Relay Fix Motorcycle Turn Signal Hyper Flash https://www.amazon.com/dp/B011BTMDQM/ref=cm_sw_r_cp_apa_KmirzbTJDKYAQ)
With a 6.5 gallon tank it would be sad to only take advantage of 70 miles at a time.... Lol
Get yourself a Voltmeter and test the resistance on the ignition pack, THE STATOR (in case you were unaware... Stator is:the stationary portion of an electric generator. It's under the right side cover. Replacements are not easy to find...trust me...) you're actually at an advantage with no wiring on these bikes. The 80s Japanese bikes were notorious for tons of wiring for no reason.)

You can look in to these relay modules they are cheap and easy to use. As for your EM interference on you previous project. Did you switch the relay with an output of the Arduino ? Because relay's are using around 50mA when switched while an output can only provide 20mA. The Arduino resets as a result.

u/njoker555 · 2 pointsr/raspberry_pi

Thank you :)

I used a simple 5v relay module, very similar to this one here: https://www.amazon.com/dp/B00E0NTPP4

The one I'm using is very old, bought it years ago and I don't remember w here, but the one in the amazon link above is very close. In my video, I show the module starting at around 6:58 - https://youtu.be/1mtX4kB1EEA?t=418

You can also use a transistor for this. Pretty much any logic-level transistor will do, or any transistor that can be turned on with 5v of power. I'm working on another project to control an RGBW LED strip, for that I'm using transistors and the models I'm using are IRL2203 and IRLU024 MOSFETs.

Keep in mind these will only come on if the cubby light is on (i.e. if the headlights are on). so if you want it to turn on when you open the door, your headlights will have to be on (for me, I have the auto headlights so it will turn on when it is dark enough. I'm not exactly sure if the auto headlights are a limited trim option or standard though)

For the 2016's its a bit harder to get to the plug to plug in the kit. Youll need to take off the driver side knee panel and the glove box entirely. Then there are two bolts that hold the bottom of the front center console (head unit and HVAC controls). There are instructions on some of the forums on how to do this.

OK, here's an approach that should work and has worked for others:

Use a TP-Link HS100 Smart WiFi/Alexa-enabled plug driving an isolated relay, e.g.. https://amazon.com/Enclosed-AC-Protection-Bounce-Terminals/dp/B017743I7S/ref=sr_1_2?ie=UTF8&qid=1483241234&sr=8-2&keywords=120v+Relay+switch

Here is a quote from a reviewer who controlled a fireplace:

>Does exactly what it's supposed to. I used this with a TP-Link Smart Plug to allow me to use my Amazon Echo turn my gas fireplace on and off. The project took literally 5 minutes to hook up and works great. If I were going to pick any nit, I wish they had a version with a solid state relay so it doesn't "click" on and off, but that's really minor, and for this price, it can't be beat.Does exactly what it's supposed to.

Setup the smart plug at an AC outlet close to the FP. Then plug the AC cord that comes with the relay module into the smart plug. The two wires that control the FP connect to the Gnd and NO contacts of the relay. Those two wires are very low voltage and current ("Millivolt circuit") that turn on the fire when connected. They should never contact a 120V circuit, which is why you need the isolated relay module.

u/zoltamatron · 1 pointr/DIY

You can get a relay like this and then connect the fan to the normally closed contacts on the relay, and the intermatic timer to the coil. And if you live somewhere with 220v then make sure to get a 220v coil version.

u/jodyw912 · 1 pointr/HomeKit

If you are up to doing a bit of wiring you can put together a rig that will work.
To do so you need to get a powered relay. There may be some on Amazon. https://www.amazon.com/Enclosed-AC-Protection-Bounce-Terminals/dp/B017743I7S/ Maybe something similar to this one but maybe one that already has a 220 plug on it.
Then use a iDevices or iHome plug to power it.
If not sure about wiring get an electrician to handle it.
Not quite a standard way of doing it but it would work.

u/I_Was_Mistaken · 1 pointr/motorcycles

Yes,
Two issues.
1.you need a digital flasher. I use these. AUDEW 2-Pin Electronic Turn Signal Flasher Relay Fix Motorcycle Turn Signal Hyper Flash https://www.amazon.com/dp/B011BTMDQM/ref=cm_sw_r_cp_tai_i_O4o4AbK3MZFNH
2.most Japanese MC’c back feed the dash indicator ( TS) from the signals themselves. The guaranteed and easy fix ( without all the resistors and janky wiring is to use one of these. Kuryakyn 4709 Diode Kit https://www.amazon.com/dp/B000TK7XMY/ref=cm_sw_r_cp_tai_i_s7o4AbN8C7F71
Then get into your headlight bucket or under the dash. Find the turn signal wires and the indicator socket. Pull out the indicator bulb holder and cut the two wires going to it. Wire up the Diode. 1 red wire connects to each right and left positive wires. The blue wire goes to the center conductor ( wire you cut ) of the indicator bulb. The black wire connects to the other wire of the indicator bulb. The black wire goes to ground - any ground wire. The left over wire ( you cut ) from the original Indicator wire just gets taped / shrink wrapped over as it is no longer used.
This will fix everyone’s “LED lights don’t work, don’t flash, stay on” problems as long as the original lights worked. This is your fix. If you ever change back to stock. It still works with no changes. This works on every Japanese bike that doesn’t work correctly with LEDS. Some bikes you can get away with changing the indicator bulb for an LED as an led bulb is a diode, but this solution only works if they didn’t backfeed the Indicator light across the negative terminal ( outer side ) of the bulb.

I’m using a Rugged Ridge antenna mount and a 2ft Firestik antenna on a medium spring. I would prefer 3ft, but I had the 2ft from my last vehicle and wanted to reuse. Like the setup on that.

Use something like Honeywell's Aube RC840T-120 and you can connect any low-voltage thermostat to control that fan.

u/SirEDCaLot · 1 pointr/homeautomation

If you want to make this work with an actual thermostat, you just need a 120v heating relay. That takes the 120v heat wires, and gives you a 24v thermostat connection for a smart thermostat.

u/ob2kenobi · 1 pointr/homeautomation

You want a relay that switches the 110v mains with a 24v signal like this:

Then you can use any of the normal smart thermostats (which switch on 24VAC).

This one (which I use) even provides the C wire (common) which the ecobee needs.

u/secret_bitcoin_login · 1 pointr/altcoin

I tinkered with two different methods, both of them use Gordon's WiringPi library to manipulate the GPIO. One of the setups uses a PowerSwitch Tail II to power off the entire machine and the other method used a simple relay to toggle the reset button. My preferred method was the firs method because it FORCED power off no matter how frozen the mobo was.

By the way - the close observer will notice that the PowerSwitch Tail is really just a relay enclosed in a box. I prefer to use it when handling 120V AC so I don't make shiny sparks.

3 wires from the nodemcu to the relay. VCC, ground and one of the datapins. Just make sure you use the 5V pin for VCC as the 3.3V ones didn't work.

Then apply power to the relay and he nodemcu. I used an old 5V cellphone charger that I cut the plug off of and direct wired it to the boards. After that I made a short 6" extension cord and split one of the wires. It goes into the relay. After that it just works.

You will need a way to solder the wires and a breadboard lets you test before doing the final wiring.

u/gimpwiz · 1 pointr/Justrolledintotheshop

1.

Which wires specifically? In general, I was planning on going for heat-shrink solder terminal connectors and crimp connectors.

One of the reasons I posted this is because there are quite a few connectors and I am still not entirely 100% sure what I need. Obviously when screwing something in to a screw terminal block, the ring crimp connectors. But when joining wires, I would prefer to use the heat-shrink-solder type, but there are also butts and blades (heh).

I bought this set of terminals, figured I'd need them anyways: Assorted crimp terminals

I am probably going to buy this set of solder terminals: Fancy solder terminals

I am pretty good at soldering (though usually circuit boards, not automotive wires, hence not entirely knowing what to do.) I have easy access to a heat gun as well.

2.

Well, both - the breaker goes on the battery, and it sets the maximum amperage for the entire new fuse block and everything attached to it. The fuses go for each individual circuit. I want to use just one fuse for each circuit, instead of having several different circuits sitting on the same fuse, largely for my own desire for neatness and debug-ability. I could have one main fuse instead of the main breaker, but I figure that they will serve the same function and I may as well go for the re-usable option.

I was going to go for this breaker: Fat breaker

That said, I bought this fuse kit, which includes up to a 35A fuse, which will be more than enough. I also bought this fuse holder, in case I decide to use one main fuse instead of one main breaker. (I figured I'd need both of these anyways for some project, may as well get them even if I don't use them right now.)

Fuse Kit

In-line Fuse Holder

---

In general, I think my system will basically look like this:

Battery 12V + Breaker = safe 12V

Save 12V + ignition 12V (do I need a fuse here?) + Relay = ignition-switched 12V

Ignition-hot 12V + Fuse Block + ATC/ATO Fuses = eight fused circuits

Fused circuits, obviously, feeding from above. I will probably add a 20A switch in line with high-power circuits, just in case, as an emergency switch.

Fused circuits will terminate at something like this Ground Bar.

 

What do you think of this proposed setup?

I do realize that it's kind of overkill for what I want.

But you can probably agree that overkill is better than your car burning down!

u/calebworth · 1 pointr/HomeKit

First this going to be removed as what to buy questions go in the meagthread sticked at the top of the feed. As for the fireplace, I don't recommend it when you're dealing with something that could set you house on fire. People do put switches on fire places here though. You can use any switch for the fan as all HomeKit switches support timers. Make a scene that turns the fan on. Set an automation for when the fan turns on turn on the scene. Make sure that the timer setting at the bottom is set to how long you want it on.

  1. Nope, it is mounted through a couple custom brackets I made out of 90° aluminum stock that mount to 2 of the bolts that hold the bumper on.
  2. I didn't run a relay. You can run a relay if you want, you will just needed a switched source (radio, cigarette lighter, etc.) to reference to turn the relay on when the car is on. That will keep you from accidentally draining the battery. I wanted to be able to run mine with the car off since I use it camping sometimes so I didn't go this route, just a fused connection. I did actually order a wiring kit for the switch and fuse which was plenty heavy (kit came 12 gauge copper stranded with the inline fuse holder and connectors and didn't draw more than 5 amps @ 12V, again just a random Amazon seller). I did source my own switch as I wanted one with the little plastic cover like this. I wouldn't bother with that again though. You can get inline blade fuse holders at most auto parts stores and the connectors at any hardware store. When I was looking at light bars, most on Amazon didn't come with the wiring hardware included so just pay attention to that.
  3. Only other thought would be look into your local laws. I have never heard of a state where they are 100% illegal, but most states have rules for how you can mount them and such (min and max height, number, down road visibility, etc.). The safest bet is that if an officer asks, it is for off highway use only.

Those wires are going to be battery, flasher out, and ground. For standard filament bulbs, just buy a 2 prong standard mechanical relay and leave the ground disconnected. If you upgrade to LED bulbs, switching to a load independent relay (usually 3 prongs) will fix the fast blink issue.

In the 3 prong the coil side seeks ground for discharge through the additional ground, otherwise it has to discharge through the circuit. Because the load (resistance) is low with LED bulbs, the capacitor that controls the coil latch timing can discharge really fast and the flasher blinks fast or not at all. There are some electronic relays without a standard coil/cap that have a rheostat in them that allows you to adjust the discharge load. Those will be 2 prong - they discharge through the bulbs/circuit. The standard mechanical relays are available at any auto parts store.

u/socal_nerdtastic · 1 pointr/learnpython

The voltage is right, but we are worried about the current. The gpio pin is designed as a signal, which means very fast switching at nearly no current. The relay however does real work and needs current to do it. The transistor will act as the switch that turns the current on at the response of a signal voltage.

You can buy a relay package made for Arduino and Pi that have the transistor and flyback diode preattached, as well as some other protection and a led. I recommend you do that instead of making it yourself.

Edit: For example: https://www.amazon.com/MCIGICM-Channel-Raspberry-Optocoupler-Expansion/dp/B072BY3KJF This one also includes an optocoupler which is a very common and highly recommended safety feature to prevent any voltage spikes on the mains from getting in to the RPi.

I did the same thing. Your favorite alexa-enabled wifi plug and one of these should do the trick.

u/niveknus · 1 pointr/e46

Take a look at your radio model number and compare it to the model numbers in this thread about aux-enabled radios. If you have one that is aux compatible, getting [an aux adapter] (https://www.amazon.com/BMW-82-11-149-389/dp/B000PA00XM) and routing it to the front isn't too difficult - just pull out radio trim piece, radio, AC unit, sunglasses tray.

I ended up drilling a hole in the bottom of the center console panel (empty space next to the passenger heated seat button) and pulling the aux port there, since I found that was much easier to reach than the glovebox.

If your radio is not aux-compatible (they all have the port, just some don't have aux mode enabled), you could always go for the GROM or similar units (the £150 fancy adaptor that they were talking about), use an emulator, or you could splice into the CD player lines.

So, here it goes, feel free to PM if I leave anything unclear.

Sorry if I was unclear....you need to have the Pi first and then building an outlet or switch is pretty cheap. The Pi and other stuff (case, sd card, powersupply) will total out to about $50 but is completely worth it because of all the other stuff you can do with them (media server, web server, whole home ad blocking, game emulation, etc)

Ill start with how to get the pi to control things and then explain how to get the echo to control the pi...

If you only want to control led strip lighting IIRC a lot of them have IR remotes and the simplest solution is probably to build an IR blaster (you will need a couple basic electronic components but cost is less than $10 even if you buy from a radioshack), and then use LIRC (http://www.lirc.org/) to emulate the remote with the Pi. The added bonus is you can then control any other IR remote device (you tv, stereo etc).

If you don't go the IR route you will use a relay to act as a switch. I have used a number of these guys for various projects: relay The basics of a relay is a small voltage opens and closes a magnetic switch that is controlling a much larger voltage. So the 3.3 volts a "general purpose input/output" (GPIO) pin a raspberry pi generates can open or close the other side of the relay that can handle household voltage. I should add the caution..."don't mess with household voltage unless you really know what you are doing you can burn down your house and kill yourself". Anyway the idea is you build a box (think electrical gang box from a home improvement store) where the power comes into the relay and then leaves onto an outlet that you want to control. I have built a couple that are the relay and outlet all in one retrofit outlet box all mounted into the wall (the relay is hidden behind the outlet it is controlling. Then you run some small gague wire (telephone 4 conductor wire works well) from the relay to the pi. The end result is the pi sends voltage on one line to the relay, the relay closes connecting the household voltage to the outlet and whatever is connected to the relay turns on. I usually include a inline 10amp fuze as well because the relays are only rated to 10A and all my breakers are 15A.

Anyway, now you have a raspberry pi that can turn an outlet on and off to tie to the echo you use a piece of software called HA-Bridge . It allows you pi to emulate a smart home device Alexa will recognize. Alexa sends on/off command to the emulated device and the pi can trigger a script to carry out your desired intent.

Right now I can walk into my basement and say "Echo, turn on the basement" Where basement is a group (grouped int he Alexa app) of several devices all emulated by the pi and the pi turns on the Tv and receiver with ir commands from LIRC, the lamps controlled by a relay turning on and off the power to a couple outlets and the Christmas Tree that is plugged into a single relay controlled outlet.

Hope this helps, it sounds like a ton of stuff but is very doable.

u/computerguy0-0 · 1 pointr/HVAC

You can use one of these with a cheap thermostat.

I personally have a relay tied into my smart house to control my basement baseboard heat.

This should work for your relays: http://www.amazon.com/SunFounder-Channel-Shield-Arduino-Raspberry/dp/B00E0NTPP4/ref=sr_1_4?ie=UTF8&qid=1449242914&sr=8-4&keywords=arduino+relay+board

It's "meant" for an Arduino, but should work with the Pi with a bit of work. It triggers on a 5v input from the Arduino, so you'd need to get the 3.3v line from the Pi's GPIO up to 5v to make it work.

You'll want to figure out the pinout of that plug with a voltmeter. I'm guessing that one of those is common and the other two are for separate banks of LEDs. To control these, you'd run the common straight through and interrupt the two banks with the relays.

As far as Pi vs Arduino, you'll have to do some tinkering either way. Neither have a RTC (real time clock) built in, so you'll either need an RTC shield or connect the Pi to a network connection so it can get the time via NTP. The Pi's main disadvantage is the 3.3v GPIO, while the Arduino's output is natively 5v.

Personally I'd use the Arduino and a cheap RTC: http://www.amazon.com/Donop-DS3231-AT24C32-precision-Arduino/dp/B00HCB7VYS/ref=sr_1_2?ie=UTF8&qid=1449243489&sr=8-2&keywords=arduino+rtc

I use a Koogeek switch with this relay plugged in:

Enclosed AC/DC Power Relay with Protection & De-Bounce. Screw Terminals. 120V Trigger Input. https://www.amazon.com/dp/B017743I7S/ref=cm_sw_r_cp_api_xVgRzbR56SQAV

The relay senses the 120v and closes the circuit of the two wires from your fireplace. In my case the fireplace had an external thermostat connected to it. I took out the two wires from the thermostat switch and connected those two wires to the relay. Now when the relay senses current it closes the circuit of the fireplace switch but without adding any electricity to it.

u/mitemouze · 1 pointr/3Dprinting

I'm still in the middle of adding a filament sensor to my OctoPrint setup so I may be missing something, but I think you should be able to use that plugin to achieve pausing a print when the power disappears. The 'Filament Sensor Reloaded' plugin just looks at a GPIO line that you select to determine if filament is present or missing and you can pause the print. If you connect the GPIO to a voltage from the same source as the printer, then you can detect the power removed from the printer and pause. A simple way to do that would be a USB power adapter with a voltage divider from 5V to 3.3V or you could use this power detector - https://www.amazon.com/Enclosed-AC-Protection-Bounce-Terminals/dp/B017743I7S/ref=sr_1_6?ie=UTF8&qid=1506368549&sr=8-6&keywords=iot+relay#Ask

For $9, I'd probably buy the power detector.

Like I said, I haven't experimented with OctoPrint pausing yet, but I would expect the same behavior as pressing the pause button.

u/neomodis · 1 pointr/CafeRacers

It's good but not great. My riding buddy says daylight visibility is ok, but to my eyes it seems a bit dim. That being said I've had several cops behind me and no issues to date.

Functionally it's been perfect except for having to redrill the plate mounting holes. As I'm sure you know it requires an LED compatible blinker relay. Another $7 Amazon purchase. Adjustable Blinker Relay

Future... I'll replace it with something brighter and more integrated. I've toyed with the thought of embedding it into a custom seat pan but it still won't be as bright as I'd like.

Based off Inkbird ITC-106RL


Parts:

Controller: Inkbird ITC-106RL
This is 12v so it is easy to use with cheap computer fans and has a built in relay to make for less wiring. Can also be ran off of a battery. Downside of the built in relay is the life span is a little lower, but it is cheap enough and easy enough to replace that I will take the trade off.

https://smile.amazon.com/gp/product/B01MS138DM


Power Supply: 12v. Can be a “wall wort” converter or hooked up to any 12v battery. I used an old power adaptor from an external power supply. Just make sure it is 12v output with at least 1 amp.

https://smile.amazon.com/Adapter-100-240V-Transformers-Switching-Adaptor/dp/B019Q3U72M/


Fan: At least 5 CFM needs to get to the drum, but keep in mind a lot will be lost going down a valve/pipe/elbow. With this controller it will run the fan as need to maintain the temp, so larger will be fine, but too large can cause problems. I did 80mm computer case fan (with LEDs) with a 3” to 1.5” ABS adaptor hacked up get it funneled into my box. I did this because I wanted the look of a big LED fan and a 80mm LED fan was cheap. I think a lot of the 32 CFM of the fan I used is being wasted with my setup with the funnel and riser pipe, and I am OK with that as I love the look. My 32 CFM fan is running about 30% of the time to maintain temp. I want to be able to glance from the house and see it light up. If you are just going for ease of build I would do 2 40mm fans screwed into the cover of the box. Then you don’t need to make the funnel/adaptor which was hard to make.

Mine: https://smile.amazon.com/gp/product/B000S396YU/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Easier:https://smile.amazon.com/2packs-0-15A-Brushless-Cooling-AB4010M12/dp/B01CZFUOD0


Temp Sensor: Any “K Type” sensor will do. The controller supports a ton of different types, but a K type is the easiest. I picked this one for the length of the sensor and the spring wire guard for having it on the side of the drum.

https://smile.amazon.com/gp/product/B00899A4LY/

This one looks great if you want to be able to remove it quickly.

K Type Adjustable Compression Spring Bayonet Sensor Thermocouple 5M https://www.amazon.com/dp/B018HX0DLM/ref=cm_sw_r_cp_apa_Ls-VzbD60N3WS

I plan on adding a clip using it on the grate as the sidewall is running about 50 degrees hotter than the air around the meat on the top grate. I think I wouldn't make this one my first choice if you going to have it on the grate because of the spring guard and size.

Case: 2" Type LB PVC Conduit Body with a pvc plumbing reducer on the bottom to get down to 3/4” pipe thread that connects to my valve (kept so I can shut it down after cooking) and a solid plug on the back drilled out to allow for a wire connector. I didn't glue either of the plugs in so I could take it off the smoker easily and for future upgrades. The holes in the face of the case were cut with a hole saw and jigsaw.

Wiring: Image from facebook.com/boganbbq

The ITC-106RL has the same wiring.



I didn’t add the switches as I am just plugging it in or unplugging it. I think I will add a switch for the fan in the future. https://smile.amazon.com/AutoEC-Rocker-Toggle-Switch-Control/dp/B012IJ35VQ/


I had to flip my probe wiring.


You may need to use a multimeter to figure out which wire is hot vs common coming from the power adaptor. Set your meter to 12v and touch the probes to the wires from the adaptor. If you get POSITIVE number close to twelve your positive/red probe is on the positive/”red” wire. If you get a NEGATIVE number on the multimeter you have them switched. I tested the adaptor on the fan first. My fan would not spin/light up with the wires switched.


My final wiring (not in the case):





Controller Settings:

The manual for the ITC-106 is bad. Luckily the IPC-16 is the same system and the manual is much better.

See: http://pmod79883.pic31.websiteonline.cn/upload/IPB-16UserManualA42.pdf


Press SET button for 3 seconds to enter into the main menu, there are Input Parameters, Output Parameters, Alarm Parameters, PID Parameters and Unit Parameters can be selected. Then press shift button to enter into the submenu if need to change the settings.


Here is what I changed to get it working. Everything else is left on the factory settings.


IP -> SC (Sensor Calibration) AS NEEDED. Once you have it running turn it on and put the sensor in the some boiling water. Use this setting to adjust as needed, keeping in mind water boils at different temps depending your elevation. I had to do a + 3.


PID -> CTL (Control Period) to 15 seconds. Basically, the system will check the temp every 15 seconds and then run the fan for the amount it guesses it will need to keep the temp correct. Lower time is more accurate temp, but on/off cycles for the relay, and it is only rated for 100,000 cycles. I think I will test this at 30 seconds and 60 seconds in the future. 15 worked well and had about a 1-2 degree swing. I am ok with more of swing if it means less wear and tear on the built in relay.


UNITS TO F if think in those terms.


In the future I will play with the autotune/self-tuning function and will add an update for that if I can figure it out and get noticeably better results.


You are done. Light your smoker, power up the controller and set your temp (you can hold the up and down buttons or use the select button and move the decimal point to change by 100s, 10s or 1s). Bottom number is your set point, top is the current temp.


I leave my 2nd valve open till 200 degrees to help the drum get to temp faster, then I closed it and let the controller do the rest, but you can start with just the fan open and walk away if you want. Exhaust open all the way. It ended up running the fan about 5 seconds on, 10 seconds off to maintain 225 degrees.

Intro

This is an overview of how I made a roughly 60% scale AIM-9L Sidewinder floor lamp for my little brother's 9th birthday.

My wife and I didn't just want to get him yet another Lego set, so this is what we decided on after trying to think of something unique, somewhat useful, and relatively inexpensive. This project ended up grossly over-budget and took about 2 weeks of working in the evenings after my real job to put together. Most of that time was spent watching paint dry and figuring out how to make this thing look decent. This was definitely a labor of love, and I would have given up almost as soon as I started if I hadn't known that he was going to absolutely love it.

I got the idea from this website, but I did not purchase or follow their plans in any way. I pretty much just looked at the photos on their website and walked around the hardware store figuring how I could make somethig like this work. This being the case, I cannot in good conscience post the exact numbers, drawings, plans, or templates I made in the process of making this lamp. If you would like to build something like this but are uncomfortable with working these things out on your own, I encourage you to check out the website mentioned above.

I do feel comfortable sharing the reference images I found with simple google searches like this, so I compiled the images that I found most useful in this imgur album..

Overall, apologies for less than stellar photo quality, I have an infamous HTC M9 with a cracked lens cover and I would drastically improve the lighting in my shop area if I owned the space. I think most of the photos get the point across though...

    Observations

    If I were to do something like this again, I would try to improve in the following areas:

  • Be better at painting.
  • Make sure the flat panels are totally flat, I had one with a rounded edge that made fitting the slots difficult.
  • Seriously, I suck at painting.
  • Drill switch mounting hole after painting stencils.
  • Cut some slots in the front fins - inside the pipe - to wrap wire around for strain relief without wasting so much length of wire.
  • Find a better way to cut the longitudinal slots for fitting the fins. You can see some gaps between the pipe and the fins.
  • Find a better solution for the stencils. Not everybody has access to a CNC laser and mine didn't work all that great anyways.
  • Different yellow paint for the front stripe.

    Conclusion

    Overall, I consider this project to be a success. It took him a second to figure out WTF is this thing, but after he got over that he absolutely loves it! I heard him say that he's going to put it by his desk and use it when he's building his model airplanes :)
u/73IRS · 1 pointr/HomeImprovement

I used this

Just use a basic Caseta on/off light switch to activate the relay. From the load side of switch just wire the neutral and hot to the relay and connect the millivolt wires to terminals that open/close as the relay functions.

That Caseta switch is used/classified as a plug in the Harmony app.

I have an activity called "Fireplace" that kicks it on. Set up that activity so that it doesn't mess with other activities that are running.

Just wish I had the ability to set a timer in Harmony to shut off the fireplace after X amount of time. Apparently you can't do that with light switches.

u/stabsthedrama · 1 pointr/CherokeeXJ

Well IMO you should use relays, since they pull a pretty damn decent amount of amps when they first fire up - so get familiar with them if you aren't already, and google bosch style relay wiring. It's pretty damn simple. You just wire to them, to a fused line to the battery, and then inside to a switch and switched power off ur fuse panel.

https://www.amazon.com/gp/product/B017VDI0GY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I made it all into a harness with both fans cuz I build deutsch harnesses all day, but really the wiring is pretty rudimentary.

I had to grind down the fan studs and chop up the efan shroud CONSIDERABLY (who knows what it's out of, snagged it off the ground at a jy). I found out later I had another stock xj fan sitting around, but I'm pretty sure even those would have slight clearance issues and would need a bit of a hack job, but it ain't hard at all.

What I can say for sure is that the stock clutch fan must be a MAJOR drag on the engine. When you see how much force it takes to spin one, you'll be shocked. My c1500's clutch fan setup is probably 1/2 the drag, if that.

u/antikotah · 1 pointr/googlehome

I'm using one of THESE along with a MonoPrice garage door Z-Wave tilt sensor, and an old Z wave outlet I had laying around. Together, I built a template cover device out of it. The tilt sensor is the feedback and the open/close commands are scripts. Each open/close script basically turns on the Z wave switch (and therefore powers the relay), then turns it off after 3 seconds. I added conditions inside each script as well. For open, it ensures someone is home and the alarm is not on, otherwise it won't work. There is also a 30 second delay, then a condition that the door is actually open or close and a notification if the proper position is not met.

I can try to post the config later on if you want it. Don't have access to it right now.
