Arduino is great for plug and play, blink an LED, using code. But if you want to understand electronics I would start here:
Easy Electronics (Make: Handbook)
^you could shoot through this book in a weekend.

After doing that book I would get this book:
Make: Electronics: Learning Through Discovery
You can purchase the parts individually or buy kits specifically made for the books. I found the kits will save you time.
I started like you a few years ago and now have moved on to arduino and am designing my own PCBs. Good luck.

First of all props to you to introduce your son to electronics and ask to find a good method for him to learn it out of interest.

I remember having electronics kits which had a bunch of simple components connected by those metal spring terminals. They often came with booklets to go step by step through simple projects to gain some understanding.

Perhaps you could look at toy shops and see if they carry some educational electronics kits? I remember book shops also sold them though I'm not sure if they'd still.

I found this on Amazon, seems a bit different with magnets snapping together but looks like it goes step by step in explaining: Looks a bit expensive but not sure if that's different in the US.

Oh boy I even found one of those kits with the spring terminals:

Best of luck!

> I'm just wondering what would be the best method for the dc 2 dc conversion, I also want to ensure the circuit can handily cope with any sudden surges in demand, while maintaining a clean and stable 5v supply.

I like the laptop PSU idea. I do that in my projects sometimes.

You may want to consider having more PSU headroom to avoid running near max capacity for your 5V reg. I snooped around and found this item. It delivers 10A from 12-24 VDC. What I can't find is a decent set of specs to give the Power Out noise (ripple). I like my 5V ultra quiet.

Envy you the PI4 BTW. Would you please tell me your RAM size and performance browsing the web? My PI3-1GB barely makes it for web browsing.

I'm using the 4GB and even with raspbian it fair zips along, I'm running with root on a usb ssd (careful not all usb3 -> sata are compatible) and that does make a difference, a 240 sdd can be cheaper than and expensive 32gb sd card and much faster... It certainly has enough power to browse the web the pi2 was torture by comparison! chromium loads in around 2-4 seconds, and feels just like its on a fairly standard laptop!

re: this Will this require some kind of heat sink, I'd prefer something as efficient as possible, I'm wondering if it might need a set of different valued capacitors on the output to help with ripple, I do have a modest oscilloscope so I should be able to see how horrid the ripple or takeup looks like I am wondering what would happen when there is sudden cpu load applied and the governor switches all 4 cores from 600hmz to 1.5ghz....!

I was a little dubious about the claims attached to the Pi4 but was pleasantly surprised, you could certainly use it as I've set mine up (root on ssd, etc), as a "daily driver"

You may be able to do something like this:

Use an RC/Drone LiPo battery:

Connect it to a switching Dc-Dc converter:

Now you have 5V, 30A available for your LEDs. Note, things will get HOT running at full power, you'll need a way to cool down the LEDs and the Dc-Dc converter.

Using that battery (75 watt hours), you should be able to power your LEDs (150watts) for about half an hour at full brightness.

Also, Id be very careful working with high capacity Lipo batteries, do your research and take precautions, they can be dangerous if not used correctly (shorting out leads/puncturing the case etc).

You may be able to find a better quality Dc-Dc converter, but make sure its a switching converter as they are much more energy efficient compared to a linear regulator Dc-Dc. 3 of these could also work:

Edit: I just realize you need 4 (not 3) * 5V/10A, or 200W power.

u/TEKTARDED · 1 pointr/diyelectronics

I completely agree with the choices and the Arduino statement as so many electronics beginners want to jump right in to Arduino and microcontroller usage without having any base electronics knowledge which is really required to use them properly.


That is one reason the 2nd Edition of Make: Electronics stands out as the better choice IMO if your only buying 1 book as it starts out with very basic circuits, gets you the fundamentals, and the progresses all the way up through Arduino usage at the end in the last few experiments. Their are also some premade kits the author suggests for the book. They are a bit pricey but they make it a lot easier for the beginner to have all of the correct parts on hand and sorted while reading each experiments.

I bought this one and some random bits for it (not sure what they're called, maybe pin housing?), and everything works great.

$23 isn't bad. The end result is worth it, and it's much faster than soldering for me

u/freezway · 1 pointr/diyelectronics

I had one of these:

Real easy to use, comes with a bunch of circuits to build, but leaves plenty open to exploration. Biggest thing is if you have a simple idea you can make it really fast and hassle free.

u/techpoi · 2 pointsr/diyelectronics

I'm learning soldering myself and have this kit. It has served me well and is adjustable, which my more experienced colleagues assure me that was a good decision. 3 months and no issues (:

u/skitso · 1 pointr/diyelectronics

You buy the $25 ratcheting ones from amazon.

I have some $600 - $900 crimpers, but DuPont like in the picture doesn’t require it.

There’s a lot of skill involved with it, don’t solder your wires to the pins, take the time and get good with them.

u/Cowabunco · 2 pointsr/diyelectronics

I just did this, I bought a siren, hooked up directly up to a power supply and plug the power supply into a smart outlet. Works fine. the only trick is to match up the voltage and current requirements of the siren with an appropriate power supply.

The siren was this: Honeywell Wave 2 siren
Takes 12 volts, 500 milliamp. Pretty sure I used this power supply (I've been buying a lot of power supplies lately) DC 12V 3A Power Adapter which was gross overkill (I would have been fine with a 1A) but it was handy, and I might hook up a flashing light too.

The siren does want to be hardwired, but I had a bunch of these power jack adapters so I put a female one on the siren so I could swap power supplies or add an extension easily.

u/2old2care · 1 pointr/diyelectronics

Ahh.. that can be beautiful if you can put each LED in a hole with all the wiring below. Those LEDs that you linked to are 12-volts. You can easily run 10 of them on a 1-amp power supply This 12-volt supply comes with a connector for bare wires. You will need to wire the LEDs in parallel for this supply. Be careful of polarity--red to + black to -.

Actually you could probably use a phone charger (5 volts, USB) but your lights would not be as bright since they have built-in current limiting resistors designed for 12 volts.

Hope this helps.

These three books are AWESOME reference materials for beginners:
Electronic Formulas, Symbols & Circuits

Timer, Op Amp, and Optoelectronic Circuits & Projects

Electronic Sensor Circuits & Projects, Volume III (Engineer's Mini Notebook)

u/Chagrinnish · 1 pointr/diyelectronics

Assuming you define a smart charger as a charger capable of charging individual cells in a pack evenly and expeditiously I would say it's not required. OP can purchase a less expensive battery protection circuit ("BPC") or protected cells (18650s with the BPC built in) and lower his charge rate to a meager amount -- but even a 1A charge rate would be fine and charge the pack in ~4 hours. The inexpensive replacement for the smart charger would then be a constant current regulator. There are lots of versions of these, some with both a voltage and current display, and of course they can be dirt cheap when purchased from your friendly Chinese reseller.

I'm not saying your answer is wrong I'm just throwing it out there as another option.

Some solid recommendations, these 2 books:
Forrest Mims: Getting Started in Electronics
Buy it:

Free to view or download here:

Make: Electronics: Learning Through Discovery
Buy it:

Also (arduino is great; but if you work through these books a little bit first you will be light years ahead when you start with arduino having learned the core concepts)

u/MakerFakerFun · 3 pointsr/diyelectronics

Checkout the Make: Electronics book by Charles Platt as their are quality electronics kits for them and should be exactly what you looking for as they start out with beginner circuits on breadboards and move on to soldering PCBs and even has some microcontroller programming projects at the end on a Arduino. The author recommends some component packs designed to follow the book on his site I'll link below that are complete and well done. I have used the book and kits myself and suggested them for a few others looking for similiar thing and never had a complaint about them.

Careful though as the Chaney kits do not cover the whole book, only the Protechtrader ones do as the authors site mentions

u/0culus_ · 2 pointsr/diyelectronics

I initially got one similar to that and it’s junk. Get this one instead. It pulls a much stronger vacuum than those plastic ones and the replaceable silicone tip lets you get right onto the work without melting anything.

u/BornOnFeb2nd · 1 pointr/diyelectronics

If you want to keep it permanently mounted, I would adapt influx's idea to a 120v signaling relay, that connects the wire between the tender and the battery. Plug it in, relay closes, tender gets connected. Unplug it, relay opens, tender can't pull juice.

Also, I don't know how many places you plan on charging your bike up but the Delran tenders have detachable cables. When I want to put it on the tender, I untuck the cable from the storage compartment, plug it in, and when I'm done, unplug and tuck again.

u/Dnadnnoid · 2 pointsr/diyelectronics

I used to put nails in boards when I was five and tie little trinkets in between them to make little circuits. I even tried plugging some into the wall.
when I was eight my grandpa bought me this I made a lot of the circuits too without really understanding much. when I was nine I tried making a dynamo for a science fair that didn't work because I didn't know the schematic symbol was just a symbol. my coil was literally a giant bent up piece of wire shaped like the schematic. I even got it to spin between a giant horse shoe magnet that my mom went through hell trying to find for me. it never worked.. My mom and dad had no idea how to help me so it was pretty frustrating. If I saw that contraption NOW I would say damn kid that's a nice model there! even though it was made of boards glue nails and wire , the concept was easy to see for the average person I think. It would have easily surpassed anything else the other kids made but I never took it to the science fair.
what I'm trying to say is he's just not old enough to really "get it" yet. thankfully he'll have some guidance from you. I used to rip apart nearly every piece of electronics we had and it really pissed off my parents. I shocked myself numerous times. even from an old TV once. that was fucking painful and my arm hurt for like a week.
when I was 15 I actually was able to take a electronics class and learn a few simple things from the teacher but the kids were distracting and I liked fucking around too so I would build me and my friends circuits real quick and then we would skip out or just melt solder.
I'm 34 now and starting to get back into it after I found some stuff in the attic. I've been looking around for breadboard and kits. your kid Might like this:

when I was a kid my grandpa also bought me an erector set and an advanced student level chemistry set. He was the only one who seemed see my potential and would get me those things. My parents would just get mad if I set anything on fire. My parents were idiots...

side thought: I need to make my own customized bread board and was thinking of using something like the spring pegs in that radio shack kit. any ideas on what those things are called?

u/GorllaDetective · 1 pointr/diyelectronics

I just received this one from Amazon today: Engineer SS-02 Solder Sucker

It’s an upgrade from an older less functional one I had. The new one has a silicone tip so it is heat resistant. The old one was too large and unwieldy and had a plastic tip.
