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 servershop24.de/hpe-gen9-sff-b 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 )?

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... 🤷‍♀️

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: aisler.net/p/UTAGNLYX (trying out this feature, please give feedback if you use it).

the delivered boards, they came in panels of 20 each. You can see both sides, one of the individual boards has been broken out of the panel and lies above them with SOT23 side up, the panel beneath has SOT363 side up. the next panel below has SOT23 up, but is only partially visible at the top.
two of the boards with soldered components. the top one has a dual NPN/PNP transistor BC847 BPN, and the lower one has a BAV70 dual diode. the area for the label is a bit small, so they only have "847" and "A4" written. the two boards are inserted into a solderless breadboard, bridging the gap in the middle, so the pins can be accessed on either side.

Failed at designing a Eurorack module.

I tried making a Eurorack mixer module since it's a module I still need and thought how hard can it be? It's essentially the hello world of modules and it failed.

I used different potis than I originally planned via the schematic and it seemed I can't get around ordering new ones since these ones were meant for a digital Arduino project anyway. So I'm not entirely sure what happened but I only get controllable hum and no volume control.

At least I tried but it seems Ive no luck with electronics. Digital Arduino stuff works fine at least.

Will see might get back at it again or order the correct parts maybe :P

Doepfer A-138n will take the open position

Proto pcb with the audi jacks hanging in thebair from testing together with a opamp and two potis.

Patch Arcana

I am just thrilled beyond belief to announce that, a full day ahead of schedule, I am releasing the newest version of the PETI firmware, version 0.5.0. This update, the Audio and Hygiene update, adds PWM-driven audio and the whole goofy poop mechanic to the game, as well as some minor QoL improvements.
