I want to do a fun project with my kids: a smash Enter key, the one you can bang as hard as you want. I only need to convince them to start soldering and trying the things together.

Also, I thought about building my own storage enclosure for a 10 inch rack. I'm just not sure how to connect it with its host system then. Using an M.2 adapter for OCuLink in the host and an OCuLink to PCIe adapter in the enclosure? Or something with eSATA? And as I thought about purchasing a backplane like https://www.servershop24.de/hpe-gen9-sff-backplane/a-116777/ I could maybe just use SFF-8087 to SATA cables. I just don't know if such a backplane can be used without a dedicated HBA controller card.
Ok all you electronical gurus.
I've got a diode that looks exactly the same as my known LL4148s but I suspect might actually be a 5v1 Zener.
What can I do (if anything) to check, assuming that my only test equipment is my Middle-of-Lidl multimeter ((which does actually have a diode test setting )?
Rainbow vomit mode for the #eurorack established. That's the starting point I needed.
WS2812B LEDs controlled by FastLED on a Arduino Nano Every, external power supply. Needed a galvanic isolated USB connector to be safe, otherwise I'd have to disconnect the external 3.5A power supply for the LEDs everytime I upload a new sketch. The Nanos should have a diode to protect against this...but better safe than sorry.
Next on the roadmap are multiple lighting modes plus a CV-based colour changing scheme for ambient sets (note values influence colour). Another input for a transistor trigger input (I'm using CV for now). And the menu...will still take some time.

I do not know if this is a good way to flip USB traces, but now both D+ and D- use one via each, rather than D+ using two vias and the other using none, and both lines are the same length so I don't need any copper rotini to tune the length of one of the legs, so... 🤷♀️

Making Sure The Basement Stays Dry With An ESP8266
I designed a #SMD adapter board using @kicad and let @aislerhq manufacture them. They are for #SOT23 on one side and #SOT363 on the other side. They bridge the gap of a #solderless #breadboard, so they are perfect for #prototyping circuits or trying out new components - or as replacement for through-hole parts. I soldered a dual diode #BAV70 on one and a dual NPN/PNP transistor #BC847BPN on a second one to try them out. I'm satisfied how they look, although the white area for labeling is a bit small - I need a thinner pen for that.
You can find the shared project here: https://aisler.net/p/UTAGNLYX (trying out this feature, please give feedback if you use it).

Seems I'll have rythmic lighting in my #eurorack case soon :>
...after I write all those damn algos to visualize it beautifully AND do all the menu work for the rotenc :(
But the CV detection works...next time I'll use a transistor.

Once upon a time I did some diy etching. After many tests to get the correct exposure, chemical procedure, and drill bit I made one glorious circuit board. Unfortunately was mirrored incorrectly and didn’t work.
Since then the kit has been gathering dust and my light sensitive copper plates have expired.
Someday I’d love to try again. If you are in Brussels go for it.
Also try wire wrap.

Anyone know a reasonable EMI induced current/voltage to design a data link for? :V

It turns out I had not, in fact, bitten off more than I could chew, though it has taken me several months, somehow, to get round to finally fettling and racking it, but still.
