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...
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

This post is meant to be sort of a postmortem for it. Now, my goal was to create some sort of PLC, capable of controlling high power loads....
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...
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)....

I highly recommend Ben Eater's channel. He's a good teacher, took his time and dedicated months to build quality content in video format, which is a rarity on Youtube these days....
I picked this little scope up from the Seapac swap meet a week and a half ago for $3. It turns out that all it needed was some contact cleaner to get it working again....
