I used to play around with 8051 variants and 8pin/16pin PICs back in 2010, whats the equivalent beginner chips now? I have been out of touch since around 2012, except for pi3/4.

I’ve been in need of a bench supply for a while, up to this point I’ve been using little buck/boost boards with a multimeter to get the voltage I want when working on a project. The limitations of that started to show though, so I was after a more ideal solution....

Hello, I did manage to kill my cheap-ish bench supply causing it to randomly output up to like 300% the set voltage when under load which did already kill one board. Probably I didn’t actively kill it but the chinesium did its job 🤷🏻‍♂️. It was a single output supply, when needed I hooked up additional buck- or...

I’m currently working on a more complex project that uses double sided assembly (and a weird USB-C connector). To practice these things a little, I ordered some low cost boards to get used to that connector and explore double sided reflow (which seems easier than I expected)....

Hi all,...

Finally got some free time was thinking about taking up new project but it got me wondering what everyone else is working on? Please share!

I did not know about this mounting method. Probably it’s a way to improve passive cooling capabilities?...

Over the past few years I’ve accumulated way too much random electronics parts and pieces from projects and random Aliexpress shopping sprees. I figured I’d split it out into various “packs”, but I can move things around as desired (or combine things). It’s all free + shipping, I can ship however you want but default...

This decade old electric cooler box gave up the ghost around 2 years ago, with the indoor outlet plug no longer working. The independent 12v input was still operational, so I kept it with the intention of eventually fixing it…...

I saw a few faces peering in the windows of r/electronics as I drove out of the car park having just locked up to head over here. Glad you found your way over.

I have this generator, joy-it.net/en/products/JT-JDS2915but it doesn’t say in the manual what maximum current this thing can provide....

Wanna reuse some old HDDs in the new PC as misc storage and I saw this on a really old drive (the PC it was pulled out of was built in I think 2008/9). Could the discoloration on E9 be because a capacitor leaked? The discoloration seems (from this side at least) to be fully contained on the circle and off of the rest of the PCB

I got a Sylvania-branded strand of 50 “warm-white” LEDs (plus two loose spares) for USD 2.50 at the local grocery store, which I’m pretty sure is cheaper than buying a bag of the bare LEDs would run. They also come in other colours (blue, cool-white, bright red, multicolour)...

A shortwave radio receiver from scratch using only cheap and easily available components, i.e. standard transistors, op-amps and 74xx logic chips. No typical radio parts – no coils, no variable capacitors, no exotic diodes.

As solder bump pitches shrink, several issues arise. Reduced bump height and surface area for bonding make it increasingly difficult to establish reliable electrical connections, necessitating precise manufacturing processes to avoid errors. Critical co-planarity and surface roughness become paramount, as even minor...
