A playable version of #DOOM on an #LEGO brick using a @[email protected] #RP2040 by @ancientjames. Uses an accelerometer and tilt for movement, and a capacitance touch sensor to shoot. Subframe sampling to make the tiny monochrome LCD give 8 gray levels (not 3 like I originally thought!). This is miraculous stuff. 😮 https://www.youtube.com/watch?v=o76U0JPrMFk

@aallan @[email protected] nitpicky, but it's 3 contrast levels - 8 grey levels

@ancientjames @aallan @Raspberry_Pi 🤩 You made progress on the battery... 👍 Is that the housing of (the end of) a original Lego 9V-Cable? Thats gonna be expensive to produce several of them...

@hsdd Yes, that little external battery is just a one-off, built into the connector from a perished cable. The lipo cell inside it is small enough to fit inside the computer brick itself, but only if I lose the USB socket. So I'm still shuffling things around to see what the neatest solution is.

@ancientjames For me the external battery or 9v supply is compleatly fine... but your arguments are valide... not everyone has 9V laying around... Power-Functions-Pins are too complicated? The PF-Cable-Ends can be bought on AliExpress and PF is overall more common...
