Clackety Keyboards Powered by Python

CatSniffer is an original multiprotocol and multiband board for sniffing, communicating, and attacking IoT (Internet of Things) devices using the latest radio IoT protocols. It is a highly portable USB stick that integrates TI CC1352, Semtech SX1262, and an RP2040 for V3 or a Microchip SAMD21E17 for V2

Some CircuitPython tricks, mostly reminders to myself

Python-based Quadcopter Flight Controller Software using a Raspberry Pi Pico, MPU-6050, and a FlySky radio transmitter & receiver

RPI Pico / Micropython library to play music through one or more buzzers, can automatically replace chords with fast arpeggios to simulate polyphony with a single buzzer. Music can be easily taken from onlinesequencer.net

Hardware design for a mechanical keyboard based on RP2040 that also has a Pi Zero onboard.

Identification of handwritten digit from images taken by a  OV7670 camera module connected to a Raspberry Pi Pico and a 120x160 TFT LCD display. The Pi Pico running CircuitPython handles everything from image acquisition to post-processing and inference. This code is somewhat experimental, but it is fun to play with.
