Vielleicht habt ihr auf vergangenen Chaos Communication Congressen, MRMCDs oder Easterheggs meine Raspberry Pi Pico basierte Arcade-Konsole gesehen, vielleicht auch damit gespielt – jetzt könnt ihr auch via #PyGame am Computer und sogar via #Pygbag im Browser (sogar mobil) damit spielen: https://simonwaldherr.github.io/DIY-Arcade-Machine/
Natürlich könnt ihr sie aber auch gerne nachbauen, Details dazu im Repo.

My hub75 based display has started having rendering issues lately. After messing around for a while and getting nowhere I believe I've finally fixed it by reducing the power supply voltage to 4.7V instead of 5V. I guess some of these displays don't really like 3.3V logic and reducing the difference helps.

The new Steam Machine is a cube measuring 160mm on a side. In completely unrelated news, Adafruit is still selling 64x64 LED matrices that measure 160mm on a side.

@PaulaMaddox Wow, this brings back memories. I had an almost identical bug in my own #FPGA #Hub75 driver.
Your bottom-most (in the photo) column looks correct; is this the first one that gets clocked out of the driver?
When do you update the ABCD mux signals? I had a bug here; I realised that you have to hold them steady until you've clocked out the entire next row, then update them at the same time as you pulse the LATCH and /OE signals.
Dunno if that helps - it was a few years ago!

Haven't seen this discussed anywhere so
Some #hub75 panels use an ASIC instead of a simple shift register for driving the LEDs to prevent burn-in etc - which means the chip expects a certain regular timing on its pins, else it goes dark. So if your simple test code isn't frigging latching and you've been debugging for hours, check your panel ICs!

a case for 2x 64x64 HUB75 led matrices, where the shell can easily be printed out of something nice (colorfabb woodfill here)

Ich habe die letzten Wochen an einem neuen Projekt gebastelt, eine DIY Arcade Konsole. Das Projekt ist natürlich #OpenSource.
Aktuell gibt es 6 Spiele (Tetris, Snake, Simon, Pong, Breakout, Qix). -
