A new stepping of the RP2350 ARM/RISC-V microcontroller fixes a number of bugs and officially supports 5V-tolerant GPIOs (however, the chip must remain powered while 5V IOs are used).
Confused NeXTstation? Nope, it's the pico-umac Mac 128k emulator running on a Raspberry Pi Pico!
Today's #RetroChallenge updates - keyboard layout rationalisation plus overclocking a #RaspberryPico to 175MHz to get a 2.1ishMHz #SharpMZ80K
Sound is now working on the #SharpMZ80K emulator as demonstrated by the standard, but dull, "Spring Fashion in 1980" demo program. #RetroChallenge #RetroComputing #RaspberryPico
Regular readers (do we have any 
) ... May remember we had a "thing" we had hoped to have ready for @emf but sadly we weren't able to get it ready in time. Well today the thing made it's first appearance at the Airbus #Stevenage Fun day.
We present to you for your delictation and entertainment the GameBoy Monumental. The screen is made up of 48 500mm x 125mm/64 x 16 pixel RGB LED display panels arranged in a 1.5m tall 2m wide display. The individual LED modules were built in to 6 off 1m by 0.5m sub panels ( 2 x 500mm squares) with each sub panel driven by a #RaspberryPico I don't have all the details yet but will provide more soon. We have some development and build photos which I will post shortly. I suspect a full technical write up should appear on our website in due course. The panels are part of a batch of over 200 we were given by London Hackspace some years ago. #RaspberryPi #RetroGaming #GameBoy #Upscale #ThisWontFitInYourPocket
Made some mini #midi 3v3 interface boards to easily add midi to microcontroller projects (mostly #rp2040 #raspberrypico these days) They even have micro leds that tell you when signal flows in or out.
PS: Für die, die mich wegen meiner Nerdseite abonniert haben, hab auch einen #RaspberryPico neu, hab aber noch nicht die richtige Verbindung zum PC herstellen können :-(
Finally done! Built myself a 2nd #chrumm diy #keyboard for the home office.
Added a #trackpoint module in the middle, which was both straightforward and a lot of work, but totally worth it 
1. tested if the model works connected directly to the #RaspberryPico using #QMK firmware
2. modified body STL in #FreeCAD to create space for the module and cables
3. Print once. Goto 2.
4. Print again
5. Assembly
6. Drillling
7. Hand-cured painted-on resin for a nice waterproof finish for the trackpoint
Hm. There is a FORTH for a RaspberryPico? That might be fun for hardware control/IOT
