A simulation based on maxwell’s equations and ohms law of a very long circuit, demonstrating how current can seem to travel faster then light.

High school is finally over! That being said, having chosen a technical school, I, like others, was asked to create a project to be shown during the oral interview with the exam commission. 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...

Blog not mine. I’m just sharing.

I found this new video. Sounds interesting… (even though i can’t keep up)...

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 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’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....

Not my video, but a helpful one. If anyone has a lead on a starter oscilloscope, please let me know.

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.
