🎉 Oh joy! A riveting #GitHub page dedicated to the thrilling world of **switch bouncing reference traces**—because who wouldn't want to spend their weekend diving into the exhilarating minutiae of switches? 🤪 Clearly, this is the height of cutting-edge innovation; maybe next we'll get a GitHub for watching paint dry. 🖌️

Switch bouncing reference traces for a variety of different switches

Speaking of soldering, I have finally rebuilt my keeb on those new PCBs . It actually went much better and cleaner this time. I’m glad I went with solid 32 gauge wire this time. It was easier to put together and it actually stays in place #keyboard #diy #electronics

I'm going to soon have to put my computer under the screwdriver. I guess it is better than putting it under the soldering iron.

y'know when you want to implement switch debouncing, and every single time you realise you haven't got a clue what the bouncing actually looks like and end up just fudging the numbers until stuff seems to mostly work as intended?

well here's some actual data! I took a bunch of different switches I had laying around and measured their bouncing behaviour, during both close and open.

graphs in the repo, CSV data available in releases.

Graph showing voltage versus time for a switch being closed, with 32 closing operations overlaid on top of each other and synchronised to the trigger. The voltage jumps around a bunch.

I need to start getting rid of this stuff and found some time for a quick tear down today. Let's make the Sony phase shifter go away!

Related to this month's Name That Ware puzzler from @bunnie I dug out my National Semiconductor NSA1166 bubble display. Close but no cigar..
I'm fascinated how the light emitting material appears to be located under the top metal anode(?)

Microscope view of a silicon die, quite distorted due to the "bubble" lens on top of it. 7 fork-like pads made of a silver-colored metal, make up the elements of the 7-segment display. The fork side of the pad has 5 prongs, with the gaps slightly wider than deep. On the bottom right segment, there's a vertical, glowing red line, which appears to be located under the prongs, extending a bit past the outer-most prongs.

Microscope view of two silicon dies, quite distorted due to the "bubble" lens on top of it. Each die has 7 fork-like pads made of a silver-colored metal, which form the elements of the 7-segment display. The fork side of the pad has 5 prongs, with the gaps slightly wider than deep. On the bottom right segment of the die on the left, there's a vertical, glowing red line, which appears to be located under the prongs, extending a bit past the outer-most prongs.

"recently" got my hands on this LED matrix display, "SAREMA VIDEO SPEAKER 150" for a few bucks. let's see what's inside

Okay, I've now realised that it's helpful to look at the specs of certain chips and their reference schematics firsthand. This stuff is usually extremely well documented and a lot can be deduced from it.

I got a used #Wii from a local retro store I wanted to support, on my side of town. Spend $75 for the bundle. Certainly higher than eBay prices, but again - wanted to support them.

Got home, only to realize that the disc drive is scuffing the discs on ejection. It's likely quite dirty internally, judging by the exterior. Should I:
