Thank you for posting this. I think they've assumed their users already know how to use it.
If I were a winner (which I am, actually, but do know what I'm doing) I would make some test batches with 0 nicotine, using the drop method. It's not even close to 100% accurate, but with what they're sending you, it's enough to get a feel for if you like DIY or not.
Mix up some 0 nicotine juice with what they send you. If you like it, order more. At that point, you'll want to invest in some actual equipment because by drops is inaccurate, but acceptable so long as you aren't using nicotine.

I remember it being much cheaper when I started than what I've linked, so maybe you can find it cheaper somewhere else, but that scale is what you need.
These are good pipettes for measuring with your new scale: https://www.amazon.com/Disposable-Plastic-Graduated-Transfer-Pipettes/dp/B00W4QJNYW/ref=sr_1_1?ie=UTF8&qid=1482206554&sr=8-1&keywords=disposable+pipette
You can, as OP said, measure by volume, using syringes, but it's messy. It's hard to convince someone who hasn't tried mixing by weight to actually invest in the equipment, but trust me, if you're even somewhat interested in DIY, you want to do it by weight, not volume.
Also, really visit the forum OP linked. I never posted much there at all but I promise you VIAB wouldn't be around without the knowledge from that forum. Read, read and read some more.
Hey guys as a heads up. In the lab if we make silicone we always degas the mixture before pouring. To degas just put the silicone after mixing into a closed container and pull vacuum. I think even a cheap aspirator will pull enough vacuum to work. Pull until the bubbles stop than you're good to go.
https://www.amazon.com/Dynalon-312635-Faucet-Aspirator-Vacuum/dp/B004AHL77E
https://www.amazon.com/Nalgene-6140-0010-Aspirator-Polypropylene-Threading/dp/B003OBYNBO
Both look promising. Google degassing silicone for more it's a common technique in soft litho.
Edit: For a chamber just get a plastic dessicator. They aren't that expensive : https://www.amazon.com/United-Scientific-55204-Polypropylene-Polycarbonate/dp/B00ES3GPMM
Edit2: Cus degassing silicone just looks so pretty : https://www.youtube.com/watch?v=bbSvzD8g_S0
Edit3: Decent part combo for degassing
https://www.amazon.com/Stainless-Chamber-Urethanes-Silicones-Epoxies/dp/B00KSWL29I/
https://www.amazon.com/Single-Stage-Rotary-Economy-Vacuum-Refrigerant/dp/B012CFTYX4/ref=pd_bxgy_236_img_2?ie=UTF8&refRID=1N0WKYM5MHVXTF9FVB8K
Remember keep the vacuum so that it slowly degasses you do not want it to bubble over and all into your chamber.
I believe it's this one: https://www.amazon.com/LabGenius-Mini-Vortex-Mixer/dp/B01CLLBZ6S?th=1

I had heard about vortex mixers for test tubes, and asked my doctor in law if she could find some cheaper than what I was seeing. Just unwrapped this from her, and I swear, I wasn't fishing for gifts!
https://www.amazon.com/Drinking-Water-Test-Kit-Pesticide/dp/B01DMF8SH6
For the price of a single month’s worth of bottled water. Although I guarantee your municipal water company does a detailed annual report and mails it to it’s customers. You probably throw it away along with most people.
Bench power supply is one of the best purchases I've ever made since getting into this hobby.
Vac systems are getting shockingly Cheap. Vac Purge Kit
with a $30 test kit?
I have this one. Goes to 120v and if you look/wait you can get it for about $120 shipped.

Definitely a little more expensive, but I highly recommend people try out a vortex mixer. They were originally made for lab work to easily and quietly mix liquids, you just push what ever you want on to the rubber top and it vibrates. I know several tattoo artists and laquerists who use them, and I ended up buying one for my paints. Absolutely amazing.
A (slow-blow) fuse or breaker would be ideal, as they are designed to handle exactly this situation. Your local hardware store probably has an assortment of fuses, and a few fuse holders.
Another option is a PTC. These are basically resistors whose resistance varies massively with temperature. They start out with almost no resistance, but if the current going through them gets too high, they get hot, and their resistance goes up drastically. So they choke down the current flow to a level that will hopefully not harm anything too badly. Disconnect the power, let them cool off, and they go back to being almost no resistance. Essentially it's like a miniature thermal breaker. These are going to be much harder for an amateur to find, though. It's not the kind of thing the local hardware store will have.
Regardless of which of the above you choose, make sure it's rated for the correct amount of current. If you need a fuse that blows at 1 amp, and you use a fuse that blows at 15 amps, then obviously it ain't gonna work right.
You talked about a 9V battery. You're probably going to be surprised how little current you can actually get out of a typical PP3 9V battery. The reason is that most of them are made of 6 series-connected alkaline cells. Each cell has internal resistance. And when you series six cells, you multiply that resistance by 6. Which by V = IR cuts the max current by 6.
Lead-acid batteries (car, motorcycle) can deliver ridiculous burst currents (100+ amps for < 1 sec), which may be what you want. But if so, be careful. You'll easily be able to make thin wire glow white-hot with those kind of currents. Also sometimes non-sealed lead-acid batteries can leak flammable hydrogen. Hydrogen + white-hot wires = bad. Finally, discharging a lead acid battery too far can ruin it.
The absolute ideal case, and also the most expensive, would be a proper bench power supply with current limiting. This would allow you to turn the voltage up and down to tweak it to exactly what you want, while having a hard current limit to avoid any burning wires. However, this option is expensive. E.g. https://www.amazon.com/dp/B073TW8H2S/

cost me 10$ in adapters from home depot to get it to hook up to my sink. works great pulls down to -25hg
This is the one I got, unfortunately the price has jumped a bit. Here's another one, though. Should be sufficient
Wow that is a ludicrous price. Most of us could flatulate a better design. Based on what I see immediately in front of me I would use two of these mk2 3d printer bed plates. Put them in series. https://www.amazon.com/dp/B01HPXA8EC/ref=cm_sw_r_cp_apa_O.vjybW7MW53F then I'd take my shittest power supply set it to 24V and maybe some constant current at 500mA to 1A and see how hit it gets under the aluminum. https://www.amazon.com/dp/B00O8DJ8QC/ref=cm_sw_r_cp_apa_ndwjyb2N27R1A
Best part you dont need a controller cause even that silly $1000 device is only giving you a adjustment pot. Then if your wife changes her mind you can start building a 3D printer.
Go to harbor freight and treat yourself to one of those laser aim non contact thermometers too. You'll marvel at how much money you saved and how even the heat is.
>[E]very chem lab should have a good number of 150-250 mL glass beakers on hand.
>Some large size glass test tubes will come in handy, and those are relatively cheap.
>Depending on what type of reactions you want to do, you may find it good to have petri dishes handy, either glass or plastic (they'd be good for crystallization experiments, certainly).
>You should definitely have a few pipettes, either the cheap plastic 3 mL kind, or if you can afford it, nicer glass droppers (Pasteur pipettes are fun to use, albeit fragile and hard to clean).

If you want to make a significant investment, you could get a magnetic stirring platform, maybe one with good heating powers. Also great for whisking up an egg, or keeping some batter moving while you make pancakes. Pricey, though.
Thanks a ton for putting together that list!
EDIT: Formatting
Unless you like pressing buttons every few minutes, I'd recommend against the one I got. I'd look for one with a heater that doesn't go above ~150f, has automatic shutoff after a set time, and has a long maximum cycle on the cleaner.
It's pretty easy to find testing kits on Amazon, but from what I've seen those cost $25-$45 each and only tell you in an analog fashion that your sperm count is above or below 20 million.
My recommendation (the rest of this is just a repost of something I posted earlier this week--sorry to anyone that's seen this before):
If you're looking for a long term solution that requires some investment but could really ease your mind...
You could buy
-A Microscope
-Some slides
-And some pipettes
...and then check your sperm count once or twice a year. All that costs about $100, but it should last you decades. I won't have my vasectomy until a couple weeks from now, but I've purchased these items and looked at my sperm under the microscope in order to get a feel for it.
Count the sperm in the 400x field of view. Record the numbers on the analysis sheet, or multiply the number by .5 to see the total. The total number of sperm is counted in millions, so a result of 72 would mean approximately 72,000,000 sperm.
According to the World Health Organisation, a man needs a sperm count of at least 20 million sperm per millilitre of ejaculate to have a chance of conceiving a child without medical intervention.
Scale. You need a scale to be accurate when mixing. A scale and some pipettes have been doing me just fine. I also have 3 clear squeeze bottles that I fill with PG/VG/NIC from my larger containers.
It's so fast to mix juice now, clean up is a breeze. I love it.
The scale I use
3ml Pipettes
I have one of these. Highly recommended (not just for knives).
They are disposable for a reason :P
It was actually the 100 pack
OK. The tank I bought for $89 bucks and I put some Mean Green cleaner to run in it. https://www.amazon.com/gp/product/B075FTFD3R
As for the Curing box, I have a lasercutter so, I used the awesome https://www.festi.info/boxes.py/ website and designed a two part slide box. I made some mods in Inkscape to accommodate my light.
I lined the box with this lasercut plastic mirror: https://www.amazon.com/gp/product/B075M7VGVM
I etched this on the outside (you have to remove the top to see it) https://images.app.goo.gl/EJGCvurAFwsE2zwN7
I bought this light: https://www.amazon.com/gp/product/B076P8SMF1
I added this solar turntable: https://www.amazon.com/gp/product/B078N3DR75
I got this off of amazon. Here is the link
Apera Instruments AI2801 801 Powerful Magnetic Lab Stirrer/Stir Plate, Speed Range: 0-2300 RPM, Max Stirring Capacity: 3000ml https://www.amazon.com/dp/B01F34Y7VK/ref=cm_sw_r_cp_api_i_BrmkDbFG8RE6S
The meter is a matter of preference. I would shop based on how it's calibrated...some use 6.86 and 4.01 solutions but meters that calibrate at 7 & 4 may be more expensive but those solutions are cheaper. I have had probes break too so don't go crazy on price. I like this one because of the case it comes with along with the calibrating fluid. I would also get some sort of dropper it will help to adjust your ph. If it is just clean water a single drop of ph down will lower the oh by several points. Aim for 5.5-6.5
Draining and replacing the water won't solve your issue right away. As long as the plant stays alive and growing it should be fine. If you can remove the plant out of the bucket and run some water over it for a few minutes and replace the water it would probably help.
Edit: found a photo of my tomato last year. This thing got like 8ft tall.

Just linked one randomly. Here's an even better deal, lol
The data stream is going to be a few kilohertz at most with these cheap 443 MHz units so that low cost USB scope will work. You only need to tap on to the data output of the 443 MHz receiver to read the data being sent.
You'll have to do manual decoding which is not hard at all. There are protocol analyzers built in to oscilloscopes, though. There is something to be said for a desktop scope particularly if it's your main scope. The "color temperature display and 256-intensity grading" feature is extremely valuable.
https://www.amazon.com/Siglent-Technologies-SDS1202X-Oscilloscope-Channels/dp/B06XZML6RD/ref=sr_1_fkmr0_1?keywords=Siglent+SDS1104X-E+100Mhz+digital+oscilloscope+2+channels+standard+decoder&amp;qid=1567190698&amp;s=industrial&amp;sr=1-1-fkmr0
To directly sample a 433 MHz signal you'd need a 5 GHz or so oscilloscope which is many thousands of dollars. You pay for speed.
edit- with on-off keying you can put something like this with a wire antenna next to the transmitter and just read the output with any scope. I can also pick up some data streams from my cell phone with this although it's not on-off keying.

I wouldn’t say there’s a lot of debate over decarbing. It’s pretty well agreed upon that if you’re going to put your extract in a cart then you need to decarb so that you 1. have an extract that’s fluid enough to wick on your cart and 2. prevent your extract from crystallizing in the cart.
If you wanna take some of the guess work out of decarbing, don’t do it before your extraction. Once you have your extract you can decarb it at 200f and instead of using a timer you can watch it bubble. As the extract decarb a you can visually see the carbon dioxide bubbling out. So once almost all of the bubbling is gone, your extract is finished decarbing and you should have a less dark concentrate.
Dry ice is what you want. Not liquid nitrogen. Nitrogen will freeze your got damn hand off. So will dry ice, but not if you’re wearing some thick gloves haha it’s like 2 dollars a pound where I live and for something small scale you should use too much.
Vacuum filtration is a MUST. You don’t necessarily need an expensive vacuum pump for this, instead you can get away with a faucet aspirator . They are pretty cheap and let you get enough of a vacuum to filter. You can get away without vacuum filtering on high micron filters without a lot of sediment, but if you want to do low micron like you mentioned or get into carbon filtering gravity filtration can take hours.
Those liquifiers can contain some real garbage in them. Pg, Vg, PEG, mct oil (mineral oil based on some independent testing of True Terpenes supposed “100% natural terpenes blend”) and who knows what else because MOST OF THEM WON’T TELL YOU. It’s a proprietary blend. If you can afford it get a blend of terpenes. Floraplex actually offers msds sheets for their products, so you know what’s in it. Mass terpenes does not do this, but they get a lot of support from the community along with Mr. Extractor. Mass terpenes and floraplex are quite affordable too!
Vacuum chamber and vacuum pump. They sell them separately or as a kit. Expensive, but a game changer with bubbles.
Thank you so much! I do add the alcohol ink to the gold. Setting up you can probably get away with spending about $50.
Here is a link to a variety pack of paints. (Gold included)
Other supplies you will need is yupo paper or a ceramic tile. Here is the kind I’ve used. However ceramic tiles are much cheaper to practice on because you can remove the ink with your rubbing alcohol and start over. I got my tiles from Lowe’s!
Some other supplies you will need is rubbing alcohol over 91% (about $2). Also some Pipettes for your rubbing alcohol.
I got mine from Amazon for about 60 bucks. It has lasted me 2 years so far. Same for my ph meter at the same price point. As long as you properly maintain it these things will last.
HM Digital COM-100 Waterproof Combo Meter for EC, TDS and Temperature, 1-Pack https://www.amazon.com/dp/B000VVVEUI/ref=cm_sw_r_cp_api_GXPvzb690905F
I didn't even know that it had all those measurement settings until I had it for a while and then decided to read through the manual hah. I was measuring using a different conversion factor than tds Nacl and my ppm numbers were super high.
After changing to the NaCl conversion factor my numbers are much closer to the bounds I mentioned in my comment.
I started mixing back in January, and here's the list of the items I got off of Amazon to get set up:
There's a few incidentals, such as nitrile gloves, eye protection(You do NOT want nicotine in your eyes!) paper towels. Bottles! How could I forget bottles?!? Again, Amazon to the rescue-just head over to 510 Central's storefront They've got some of the best HDPE bottles on Amazon-Nice and squeezy but firm. If glass is more your thing, I'm sure there's a bunch of those on Amazon too.
Here's a little tip I use: When mixing, put your VG and PG in some condiment-style bottles(I picked up a couple at a craft store in the candy making dept) When you're mixing in small bottles, it saves time and mess to pour from a squeeze bottle than a syringe. Syringes and VG don't work too well-It's like sucking snot up a straw.
I'm also going to say head over to /r/DIY_eJuice and read up on mixing. There's a TON of great info in the sidebar-READ ALL OF IT. When you get ready to start mixing, pick 2 or 3 recipes that sound good and buy the flavors for those. It's a lot easier and less expensive than buying a slew of flavors that sound great but don't play well with others. Enjoy!
A vortex mixer

Are you in college? Or is there a nearby college you can make friends with? This is the sort of equipment they should absolutely have on hand.
If you're able to transport yourself, this may be a great place to look: https://www.electronicsfleamarket.com/schedule
Otherwise, I've no experience with these, but you might check out standalone units like this: https://www.amazon.com/Handheld-Oscilloscopes-DSO-Nano-V3/dp/B015X6LZFO
There's also stuff like this where you might be able to get more bang for your buck if you're able to supply a computer: https://www.electronicproducts.com/Test_and_Measurement/Benchtop_Rack_Mountable/Top_7_PC_based_USB_oscilloscopes_of_2017_for_hobbyists_makers_and_pros.aspx
Or go the engineering route and DIY: https://hackaday.com/tag/diy-oscilloscope/
I know you asked for a higher end one, but [THIS] (https://www.amazon.com/dp/B009B2BIKY/ref=cm_sw_r_cp_api_URbhybGESJPT4) is what I have and I couldn't be happier with it. It's the same one Hornady sells but without the upcharge for their logo.
Buy this and a 5gal bucket of purple power and you're g2g
Use these to move paint from pot to mixing location and also to move from mixing location to airbrush.
Get you some Refillable Plastic Atomizers and some Pipettes. Then if you're really crafty, a label maker or strip of paper with some clear tape over the side for a label.
You can also buy a water testing kit if you want. It's overkill to send it to a lab right away. You should do the kit first to see if it tests positive for lead, if it does then send the water out to a lab to see how much is in your water.
Few options at that price point.
Others have already mentioned Owen and Rigol, I'd add https://www.amazon.com/Siglent-Technologies-SDS1202X-E-Oscilloscope-Channels/dp/B06XZML6RD/ref=redir_mobile_desktop?_encoding=UTF8&amp;keywords=siglent%20oscilloscope&amp;qid=1503249344&amp;ref_=mp_s_a_1_1&amp;sr=8-1 siglent. They are all about the same quality scope,great for hobbiest but not the best for daily use. I believe keysight just came out with a dsox1000 pretty close to your price set as well.
When I feed frozen daphnia or other frozen food, I use these little plastic pipettes I got in bulk from amazon. They're also great for dosing prime, my fertilizers, and test kit test tubes. And they're cheep enough to toss after they've been used for the food.
They're small enough to aim the daphnia right in an airhead bettas face.

Here's the one I bought,
https://smile.amazon.com/gp/aw/d/B075FTFD3R?psc=1&amp;ref=ppx_pop_mob_b_asin_title
Works great, no mess and prints get cleaned really well, quick too. And then I just get the mean green at a local dollar store. It can be ordered online as well if you can't find it local.
I ended up going with an adjustable amp/volt power supply.
I have this and it seems to work.
I have a cheap 2.5L one. Enough to do an 11-32 cassette and chain at a time. Great widgets.
Add a little bit of Rock'n'Roll Miracle degreaser to the water, turn it on and walk away and do other things than scrub. You really don't need anything that aggressive/toxic, people use Simple Green--but that is really overkill IMHO.
Gesswein is Canadian, as is Caswell.
Not knowing where you are, I suggest you searching for a jeweller's supply shop.
In Vancouver there is Lacy West.
I'm pretty sure Rio Grande and/or Ottofrei will ship those chemicals to Canada.
Edited to add, I purchased this power supply from Amazon.com with no problems.

This is the one I have. Yeah it's pricey but it mixes ANY paint I throw at it in less than 5 seconds with no effort on my part. It has sped up my ability to paint and it has increased the quality of the paint itself by mixing so thoroughly. It's 100% worth it.
It all depends on what speeds you need. I regularly look at signals between 100MHz and 200MHz, so I recently bought https://www.amazon.com/gp/product/B06XZML6RD/ which is the cheapest I could find a 200 MHz scope. It's also seems to be the breakpoint for scope bandwidth on a budget - anything faster was over $1000 instead of ~$400.
Logic analyzers make more sense for digital work... but if your problem can be solved with a logic analyzer you can usually use the internal one (Each FPGA brand has something that works similarly: Chipscope, SignalTap, Reveal).
I only pull out a scope when I'm worried about analog fuckery like contention/ringing/rise time issues.
I use [this one] (http://www.amazon.com/gp/product/B009B2BIKY/ref=oh_aui_search_detailpage?ie=UTF8&amp;psc=1). It has a heating element and the timer runs for a max of eight minutes.
I've found that a little over three hours of cycling (about 40 cycles) in the cleaner steeps about the same as two weeks conventional. I transfer my juices to glass bottles before running in the cleaner. My cleaner is in the kitchen, so I run it whenever I'm in the room, turning on the heat every two or three cycles.
I usually just soak my rebuildables in a glass of isopropyl alcohol, but sometimes I'll stick the glass into the cleaner's water tank (filled) for a few cycles, though other than the drip tips I can't claim that it makes any big difference in cleaning.
Be careful with plastic clear pieces, they can etch and become cloudy with repeated cleanings, though being diligent with changing the cleaning solution may mitigate that.
Northern Brewer is having a sale on their stir plate. Personally, I own this one. I love it and use it all the time when making starters.
Get a stand mixer?
Otherwise you'd need a magnetic stirrer like this
https://www.amazon.com/gp/aw/d/B01F34Y7VK/ref=mp_s_a_1_3?ie=UTF8&amp;qid=1505174197&amp;sr=8-3&amp;pi=AC_SX236_SY340_FMwebp_QL65&amp;keywords=magnetic+stirrer&amp;dpPl=1&amp;dpID=41SwyGAs5%2BL&amp;ref=plSrch
Also best to use pipettes like these to get water from your tank. Do NOT scoop water out with the test tubes even if you think you cleaned them as it can be easy enough to leave even a residue in it and that can poison your fish. Years ago, I had some unknown death in a tank and that was the only thing we could think of.
I use these multiple times not just using once and throwing away. I keep one for each tank. Then I also have one rubber-banded to each bottle of Excel, Flourish, and anything else. If the tip touches the tank water, then I toss. The package will last ages.
Lately I've been using disposable pipettes for decanting and some filling. I also trim the tip down to fit into the back of the section for bulb-flushing. I got a pack of like 100 on Amazon for pennies per pipette. http://www.amazon.com/gp/product/B005Z4QVZ4/ref=oh_aui_detailpage_o08_s00?ie=UTF8&amp;psc=1
http://www.amazon.com/gp/product/B000VVVEUI/ref=oh_details_o09_s00_i00?ie=UTF8&amp;psc=1
It's this. Apparently I can measure in EC. Gonna have to read the manual. :-)
Thanks!
Pipettes usually are really slender and long and used for the same purposes.
https://www.amazon.com/dp/B01G82SJRY/ref=cm_sw_r_cp_apa_RueIAbY8BAF1M
Found a nice mini magnetic stirrer on amazon for ~$85. Would be a super nice convenience but I'll continue to live without cause I'm a cheap SoB.
I should mention that I'm old school despite being new though too. No ultra sonic or even a frother. I just give em a good shake and let them cure over time (sometimes I'll do a hot water bath but have been even too lazy to do that lately). Then again, that's what happens when your closet looks like this (ready to vape juices) and if you ever want more flavors. Yes my caps are off at the moment, happens once a week for a day.
Affordable oscope if OP goes this route. This will be most accurate, but a multimeter will suffice.
Don't measure mililiters with a scale, measure it by volume (since you're doing volumetric comparison).
If you're going to be adding flavors to beer on the regular, a pack of these costs basically $0 and will last you a long time, and have applications outside of brewing.

You'll want a DC 0-120v variable power supply. There are some 1 amp models on Amazon that go for about
$120$150. They will get you the entire range of colors.Color is dependent on a few variables. But the biggest is voltage. Green is considered the hardest to get since it's at the 95-98v range.
The 1amp variant is a great intro to it but can struggle depending how much titanium surface area you are trying to anodize.
Edit: this is the one I started with and used for almost 2 years
You are looking at it the correct way. You want to be pretty exact when it comes to the power supply. Some electronics have more or less tolerance to the power supply being exact than others, so you can’t 100% rule out that you just don’t have the right one. Depending on your budget there’s a couple different things you can do. 1) try to email peavy customer support and tell them the exact model you have and if they can sell a power supply to you or recommend one that would work from their existing parts supply. If you’re lucky, they should be able to send you a power supply for pretty cheap (maybe $10-40 shipped...? Just a guess tho).
2) if you can’t get it from peavy, look for that exact voltage and amperage power supply from any electronics supplier online. If the barrel plug doesn’t exactly fit, splice it onto one that does fit the peavy.
3) the slightly more expensive option, but as you were indicating, you want to know whether or not it’s a power supply issue first. Over the years of investing in electronics, I eventually got a bench tester. This one :bench tester
It allows you to finely dial in whatever voltage and amperage setting you need to properly power your dc circuit. This is a really helpful tool to have and will
Allow you to provide power to any dc electronics that you’re troubleshooting or prototyping. Obviously if you’re trying to just stick to making work what you already have, it might be prohibitively expensive, but In the lifetime of working with electronics, this and a multimeter are invaluable
Although the theory and understanding of nodes and meshes from circuit theory is important, practical electronics-level knowledge can be found in The Art of Electronics. See genlib, but I suggest to buy it and get some basic electronics kit, a power supply (a proper lab supply with adjustable voltage and current limit [1]) and a breadboard and create the circuits that you're studying, play with the basic devices, and make a project once you get the hang of stringing logical blocks of circuit components together.
I find it fun :)
[1] SOmething like https://www.amazon.com/Adjustable-Eventek-KPS3010D-Switching-Regulated/dp/B073TW8H2S/ref=sr_1_5?keywords=lab+power+supply&qid=1565149853&s=gateway&sr=8-5
It is the same chassis as my current supply, maybe same actual device inside, but I found it for more like $60 a few years back. The key is the ability to set a current limit, so when you hook something up incorrectly the circuit doesn't fry.
Something like this?
Edit: 3ml

This is all I need right? Will it come calibrated/with some solution?
You might ask /r/audiorepair to see if anyone has a lead on a schematic. Make sure the output relay is clicking and try using the front/rear channels as well. In cases like this it helps to have an oscilliscope to probe the signal as it goes through the amp and see where it stops. I have a $85 DSO Nano V3 specifically for this and the fact that it's battery powered helps keep things safe since there is no path to ground.
Cool, those ESS have Heil AMTs. Sounds like a good project.
Joy4Less Professional Grade Ultrasonic Cleaner 4820WPT with Heater and Digital Timer https://www.amazon.com/dp/B009B2BIKY/ref=cm_sw_r_awd_k34.tb1DS40Y7
It's pretty damn good. 8 minute cycle, and the heater gets scolding hot with a quickness.
Have had it for over a year now and still works as good as new. I use it frequently.
Magnetic stirrer thingy would last longer and make less noise. :)
Edit: One of these
Get one of those faucet asperators
14$ http://www.amazon.com/Nalgene-6140-0010-Aspirator-Polypropylene-Threading/dp/B003OBYNBO
Just make sure your hose water isn't going down the drain - because you don't want your butane down there :P
I'm gonna drop my resin links here and some short descriptions
First off, get some various sizes buckets or containers for cleaning. I find that these sanitation pails are great. You can also just get cheap Tupperware. I use these for cleaning vats, tools, and I always set the bottle in them when refilling.
https://www.amazon.com/dp/B07NC1WCJ5/ref=cm_sw_r_cp_apa_i_kxtqDbNDXDS96
You should also get a good respirator. Any hardware store should have one.
For curing I made an acrylic box and put this lamp on it.
You could use cheaper LED strips etc. https://www.amazon.com/dp/B01LT53312/ref=cm_sw_r_cp_apa_i_dBtqDb0VTGF28
Box. I use something similar with a mirror on the bottom. You could add foil or mirror film for the same effect.
https://www.amazon.com/dp/B0014QTXPW/ref=cm_sw_r_cp_apa_i_fEtqDbZ997GN6
Funnels, any hardware store has them. I bought a large oil funnel that I put the paint filter in and the tray also fits in. And just hang it above the bottle.
A ton of IPA! Hardware stores have this in 1 gallon tins.
Pro-tip this thing... But it's completely not necessary. https://www.amazon.com/dp/B075FTFD3R/ref=cm_sw_r_cp_apa_i_xLtqDbMGD060V
Mines pretty old so I've been looking at getting a new one & this one is big enough to hold a decent amount of switches, has good reviews, & is decently priced. Although Amazon has plenty of them & if you do not see yourself using it much in the future I'd go for a cheaper one. Just make sure it's not a really small one if you go the cheap route.
Plastic suction tool. You can buy them in bulk on Amazon for next to nothing.
Yes please be safe and use a Purge to be sure extracts are clean.

I bought 150 plastic ones from amazon. I don't really worry too much about rinsing them out, so they're basically disposable.
https://smile.amazon.com/Teenitor-Plastic-Transfer-Pipettes-Dropper/dp/B01G82SJRY
Oils are nonpolar, so you would probably get the best extraction with a nonpolar solvent (i.e. not water). The easiest starting point would be to use Everclear (95% ethanol) to extract from some chopped up hops, filter it, then slowly evaporate the alcohol.
You also might try some other high fat food products (milk, plant oils, butter, meat fat) to do the extraction, but it will be impossible to separate your solvent from the hop oil.
It probably wouldn't hurt you to read that info about THC (or even caffeine) extraction. A lot of the same principles will apply.
If you want to go further, look into converting your kitchen sink to a water aspirator pump or making a CO2 extractor yourself.
Lastly, I have no idea if this would work, but maybe you could make a "hop espresso/tea" with a moka pot? Also try with everclear.
I just take a plastic pipette, and refill my preppy cartridges. $5 for 100 pipettes that can be used for multiple pens, or $7 for the converter that is easier to use, but only for one pen. I guess it's a matter of preference really.
Here's some options, they are all basically the same:
Soak the equipment for 10 minutes or use an ultrasonic cleaner if you want to be extra thorough.
I don't bottle much--only when a batch is over 5 gallons--but last time I made a syrup to prime three litres and dosed it into three 1 litre swing-tops using a marked pipette.
One of these. Although I only paid $75 for mine.
Get this
Ultrasonic cleaner. Water in the reservoir. Disassemble cooling unit, detach O-rings and set aside. Put disassembled parts into a portion control zip-loc bag with iso. Zip bag, toss into the water, and depending on your USC, mine does a 90 second option. I run that once, check on it, and run it again if necessary— but it hasn’t been yet. The zip-loc bag helps conserve iso, and also lets you do a few batches at once. I typically run a bag full of ELBs from my EVO, mighty cooling unit, and stems from my solo 2 in three separate baggies. Cleaner works a charm on my orbiter and countless GonG adapters, too. Then just rinse everything in water (or do a run in the usc with just water). Paid like $70 for the thing on amazon and it’s already paid for itself. Another poster below said something to the effect of “if cleaning is easy, you do it more routinely.” This is true. My last thought? I look at it like a $70 new vape, because it basically resets all your vapes and glass to factory fresh. For example, I had no concept for how much difference brand new ELBs make on the EVO. I now clean them weekly. Takes less than 5 minutes!
Edit: price was slightly off, and to add a link. THIS is the ultrasonic cleaner I use. but there are many cheaper options out there that probably do the same job. I just don’t have a ton of space in my apartment, and it blends in with our other kitchen Gizmos, so for those reasons it was worth the premium.
You could get some labeled plastic pipettes like these and put the same milliliters in every time?
We bought a water testing kit when we moved in (this one for the curious) and tested our tap water over concerns about lead, once everything came up fine (on the test ran twice, a week apart) we drink tap water sometimes now and use it for cooking. We also have a brita in the fridge that I use more frequently (mostly because I prefer the colder water tbh, but nice to have the extra security).
Surprisingly not really unlike Oregon. Where we have hundreds of farms, and ridiculously cheap flower, but so little oversight that they grew so much weed that there’s like literally a million pounds just sitting there waiting to either be sold, turned into oil, or go bad.
I’ve always wanted to come to Israel but my health hasn’t allowed for it. I’m kind of out of town Modern Orthodox. My sister managed to get out of here though. She went to seminary at Neve Yerushalayim when she was 17, moved to Manhattan, and has only come back a few times in the 6 years since. Oregon is too treif for her now lol.
I do know some people there who have made small amounts of their own though. It’s not something I recommend doing if you live in a city, but something that I imagine you could get away with easily by driving off into the desert or something. And everything necessary other than the herb, including the butane is available on Amazon. This is a good starting point.
Ablaze Stainless Steel Open End Tube Kit 45 Gram (No Tripod) https://www.amazon.com/dp/B01MS0BTGG/ref=cm_sw_r_cp_api_i_kv2VCb729DWJS
With one of those, all you’d need is butane, which is also available on Amazon.
If you want to take your product a step further, you can add a quality vacuum purger that comes with a pump for right around $150 now. All in all very little expense required to make something very valuable in places where it’s hard to find.

Generally you should follow the instructions on the fertilizer as instructed, if there are any. Then test your water with a TDS meter to ensure you have acheived the right concentration. I use this one.
Hopefully you picked a water soluble fertilizer, preferably one meant for hydroponics. I have heard of getting by with other fertilizers such as miracle-gro but this kind seems like a hack job to me personally. General Hydroponics make some cheap and effective hydro concentrates that are a good place for beginners
I use Pipettes and count the drops. This makes it simple when mixing custom colors since you can easily write down the total number of drops per color. I also have a bunch of empty Testors paint jars left from my model car building days that I use to mix my paint in.
I can't respect a video where someone shrinks their tubing with a lighter. Get a heat gun you savage!
Personally I started to make a bench supply out of an old ATX power supply (though I was just going to provide 12 and 5v outputs and deal with stepping it down externally) when I came across a good deal on one of the cheapies like this. A project is nice but I had other things I wanted to get to where this would be helpful.
I've been debating getting just a magnetic stirrer like this one
http://www.amazon.com/Hanna-Instruments-Magnetic-Mini-Stirrer-Speedsafe/dp/B002OSX2Q0/ref=lp_318023011_1_4?s=industrial&amp;ie=UTF8&amp;qid=1451487697&amp;sr=1-4#customerReviews
I use an O'tool module for a scope which I like because it's a lot smaller than the Mordax. You can probably score a used version 1 pretty easily.
There's also this:
https://www.amazon.com/Handheld-Oscilloscopes-DSO-Nano-V3/dp/B015X6LZFO
There's a cheaper version of that somewhere as well.EDIT: Found it. https://www.adafruit.com/product/468
If you're going to vape like he suggested here's what to get.
For VG/PG this is food grade and what everybody uses: https://www.amazon.com/Glycerin-Vegetable-Kosher-USP-Quart/dp/B004C7MTLA/
Here's the scale everybody uses which goes down to .01 grams and is flawless: https://www.amazon.com/gp/product/B005UGBG20
Sign up for http://e-liquid-recipes.com/ and then you can use the calculator to measure with grams and break down the pg/vg nic and flavors which is the tool all DIY e-juice use. Back in the day we did it by volume which was a pain in the ass and doing it by grams is a game changer.
I wouldn't bother with nic but if you do choose so nudenicotine.com offer a free sample ($3 shipping) get the 100mg pg version. If you do go into ecigs DIY section for safety. Although if you have common sense it's actually very easy and safe but go to the right section in DIY.
Get pippets: https://www.amazon.com/Teenitor-Plastic-Transfer-Pipettes-Dropper/dp/B01G82SJRY/
Get some latex gloves or something.
If you're going to add flavoring this is my favorite: http://www.bullcityflavors.com/natural-mint-wg-inw/ - or their mixed mint which is the same but menthol - Eucalyptus will clear your sinus for a year.
INW is a premium flavoring company because $2-3 dollars for flavoring is expenisve in the juice world, that's why every vapor should DIY but they get overwhelmed with all the info, but it's easy as hell. The 10ml (don't bet the 30) will last you probably your whole life. I would go either 1% or 2% using the calulator, I couldn't imagine using anything above 3% because it's so crazy concontrated.
I’ve been using mineral oil on any knives that might cut food and gun oil on others for a long time. I got some of these some time back to use with mineral oil and also for alcohol when I’m cleaning. They work really well.
My friend, let me introduce you to the Vortex Mixer. As Coyotebd said, it does the job super well, no matter what paint you are using. It is seconds and its mixed. Personally for me, Vallejo has been the hardest for me to mix up, some times the colors separate a little and its hard to get them all mixed up again. The mixer took care of that in seconds. Get one if all you have is dropper bottles, but it works well with GW also, but make sure the lid is nice and tight.

If you are wanting to make large batches of juice I would consider a magnetic lab mixer. Like u/jackholexxxx said though watch what your vg/pg mix is because the mixer may not be powerful enough to mix the amounts you want. I have found with mine that 360ml is ideal but I also haven't tried larger mixing bars then what came with it.
I'm sorry to be pinging you in multiple spots lmao, but do you think these pipettes will be fine?
https://www.amazon.com/gp/product/B06ZZLQ2XN
I bought this. It has served me well through circuits and electronics classes. You can find a combo beadboard/components kit on Amazon.
I bought this one in Jan this year and works fine: https://www.amazon.com/gp/product/B01F34Y7VK/
Luckily the valves and timing were recently done by a pro. Not looking forward to doing them myself!
The carbs were cleaned too, but you're saying to put them in a ultrasonic cleaner?
I've been thinking there could be an issue with one of my floats, I hear they stop working well or get fuel in them.
Either buy the carbonation tablets or use these: https://www.amazon.com/gp/product/B00P7QZDK4/
3/4 cup of simple syrup divvied up 50 ways is about 3 mL.
I was just on amazon looking for that a minute ago. I only have 50 bucks to spend right now and there is one for just under that.
Here it is.
I am not sure if this is also a ph meter, but I have no problems with ph, I'd just like to get my ppm right and bonus if I can get ph meter combo for the same price.
Does anyone have any experience with this or recommend a different $50 model?
Without a doubt. I recommend this one if you want a cheap starter to try out: https://www.amazon.com/gp/product/B072JXQ9P5/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
I use it for my bcg, suppressor, and my handguns.
