Want to make weird little synths? You can do it in #CircuitPython! Here's a refresh of my two-knob drone synth, now with echo effect and two buttons: pitch LFO & note release to hear echo effect

The eyes are coming! Happy Halloween!
(That is, the #CircuitPython eyes on a multi display build for #RaspberryPiPico. I'm reposting older stuff that used to be on birdsite)
DIY Raspberry Pi Pico MIDI to CV converter pt.2: Dual CV output, distance sensor & Neopixels

Finally seem to have finished this beast of a project. Or at least the files for the prototype of it. More info coming soon :)
Thinking of releasing a new MIDI controller, but “pad trigger” style rather than “music keyboard”. What do people think? Yes?
Could make a good macropad too. It has reverse-mounted neopixels that shine through the PCB to light up next to the pads. Looks pretty cool I think! The sounds you hear are an off-screen laptop running Ableton, this is just a USB device, it doesn't make sound. Demo code in CircuitPython

The Pico2 RP2350 input bug I mention in the latest episode of @thebootloader is not theoretical, but impacting commercial products like the Bus Pirate (see https://mastodon.social/@buspirate/113073772302750924) and all my captouch-based MIDI controllers & synths in my Tindie store. I don’t recommend Pico2 for newbies either: even their official tutorial code will not work on a Pico2 https://projects.raspberrypi.org/en/projects/getting-started-with-the-pico/6

Okay here’s a thing from an hour of goofin’: algorithmic music generator using a rotary encoder, a round TFT, and an I2S DAC in CircuitPython

Ooo just got a #Pico2 to round out my growing #RP2350 board collection. What quick project to make with it…

Thinking about how to store some persistent information in flash, stashed at address 0x80000 or something, alongside the main binary, on a Raspberry Pi Pico.
I'm kind of torn between trying to keep things compact, I'm storing fairly short strings and such, so how much space to I need to reserve, really?
On the flip side, I'm using an 8MB flash chip, so there's plenty of room for each property to have its own 256 byte page just for convenience.
Here it comes, #CircuitPythonDay2024!
In celebration, a sketch that somewhat recreates the THX "Deep Note" sound on SparkFun Pro Micro #RP2350.
The messy code: https://gist.github.com/todbot/046b1c8243002ef76c5e2fabae84ba0e
