I’m nowhereman from Belgium. Thanks for accepting me! Just started with electronics. Messing around a bit with motherboards. My ‘new’ secondhand motherboard got hit by the ground a think whilst in transport. And when I plugged it in some chips burned. The board didn’t look like it would do that. Only the corner was hit...
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)...
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’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....

Would anyone like to chime in. I recently made an MOT spot welder for 18650 nickel strips. I can reliably weld 0.2mm nickel. Although I do need a slit if I’m doing nickel nickel (stacking for more amps)....
Hi all,...
Arguments to support the idea:...
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.
Not my post/video. Link to mastodon.social post which then links to YouTube video....
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...
Although you are probably not aware of them, dozens of electronic control units (ECUs) — printed circuit boards (PCBs) in metal or plastic housings — exist in your car to control and monitor the operation and safety of your vehicle’s many control systems. These units must work for the lifetime of your car, during which...
