Man, am I tired. After getting braids running on Peach (hacked) we (Felix from WGD) found a bug in Chambord, our sampler. Then, MMM arrived in the mail ... I've posted a little update: https://poetaster.org/news/2025-06-13/ There's an audio snippit .... #DIY #MutableInstruments #pipico2 A really big thanks to Niek and to the #RaspberryPi folk for all these years of great little machines!
#pipico2
Good news! The #RaspberryPiPico 2 is a drop-in replacement for the original Pico in the #PsiDrive!
It seems that the pulldown issue-that-is-officially-not-an-issue doesn't affect this version of the PsiDrive board. I've tried dumping a ROM SSD and it worked with no changes to the code.
Very happy!
@hon1nbo @foone Granted, the only ones willing to pay even a $50 premium per System to get this done are either so paranoid they don't buy keyboards but specifically contract a "secure manufacturer" (i.e. #Cherry) and demand the sourcecode and schematics as well as reference dumps and Xray images (i.e. #BND in #Germany) or do that shit inhouse from scratch.
- Still, a truly end-to-end encrypted, fully self-custody capable "secure HID port" would be interesting.
I'm shure something like that is possible with a #PiPico2 on both ends, necessitating manual handshaking and setting stuff in clear resin to make it tamper-evident!
#Micropython 1.24.0 has been released!

"A Surprise Hardware Bug in Raspberry Pi's RP2350 Leads to Unexpected Pull-Down Behavior"
"That issue ... affects all GPIO pins: when configured as an input that uses the internal pull-down resistor and with the output buffer disabled, a GPIO pin will latch at between 2.1-2.2V rather than be pulled back to ground — but only after its first use."
