So, things completed on the fight stick for initial testing:

- Stability testing under Windows (about 2 hours)
- Stability testing on the PS1 (about 3 hours)
- Compatibility with the Brook Universal Fighting Board (4-in-1)

Left to test:

- Stability testing on the MiSTer
- Compatibility with the Brook Universal Fighting Board (Fusion)
- Compatibility with the Brook Zero-Pi Fighting Board

Things are going smoothly so far overall. #gaming #fightstick #electronics

I received an old car radio some time ago and decided to scrape components from it. One of the chips was a TEA6330T sound fader, that miraculously has a not classified datasheet ( pdf1.alldatasheet.com/datashee ) so naturally i decided to bring it back to life with a custom Arduino library!
You can view the lib on my github here: github.com/adreline/TEA6330T
The library includes functions for every option the documentation mentions. I tested it without actual speakers but the chip responded correctly to all the commands. Sound test remains on my todo list.

pdf1.alldatasheet.comTEA6330T PDFPart #: TEA6330T. Description: Sound fader control circuit for car radios. File Size: 158.7 Kbytes. Manufacturer: NXP Semiconductors.

does anyone have a resource on how one would go about creating an IBIS model for a device that does not have published SPICE or IBIS models?

I'm looking for info on how I would go about performing the characterisation measurements, and how I would then transform that data into an IBIS model.

it doesn't need to be super accurate and I'm not measuring particularly challenging ICs. I mostly just care about having a ballpark-correct IBIS model for SI simulations in Altium.

Dear fediverse,

what is the best resource of do's and dont's for setting up a #repaircafe ?

I guess not what I do with my own repairs : 40 boxes with half broken stuff from other people, waiting to find that single crucial part, schematic, or plans to fix it with a 3d printed part (to be designed and printed), actually converting my place in a #dumpsterdive without divers.

Neither desoldering all weird parts because weird parts are difficult to get...

Question to all the #ee or #electronics experts here: I have two TI chips here. the one in the background is from 1985 and has shiny legs. The one in the foreground I bought in the last 5 years new from Mouser. It came with those tarnished legs already from the factory. Why are the legs so tarnished? What coating does TI use that makes it so black looking. I understand that back in the 70s supposedly TI used a silver coating that turned black over the decades, but this is something different...?

Two chips, one DIP16 packaged SN74LS166 and one DIP20 packaged SN74LS245. The latter has tarnished pins, while the other looks shiny.

Bionic cat ears. I want bionic cat ears... So I ordered an EMG electrodes and will be experimenting with interfacing them with my earlobe muscles and an mcu to drive a linear actuator that will move the cat ears on my head. Ideally i want silent operation, which can be achieved with a pull action electromagnets. Before buying those tho, i will just use some servos i have laying around

(this is a part 1 of a bionic cat ears project)
