  Following on from my post on i2s playback with Raspberry Pi Pico, this is a write up of the recording lab notes I made in 2023. This was actually the trickier bit - getting an i2s MEMS microphone to capture audio and write it to a WAV file on an SD card. I completed this in 2023, but only got round to writing it up in 2026 - better late than never!more...

  07 Jun 2025 » Preparing for the coder dojo

  Last night, I got some preparation for today’s Coder Dojo KU Python Robotics activity. These are MicroPython robots based on an RP2040 (the Raspberry Pi Pico chip). The activity is aimed at kids learning to code. I have a fleet of 10 robots, plus 1 more as a demo/test model. It uses some of the principles from my books. These autonomous car type robots are built around the Cytron MakerPi RP2040 control board, with a dual RCWL-1601 sensor for obstacle avoidance, a Maker Line 5-sensor array, and a mini-3 round chassis. The code is written in MicroPython, and the kids write their own code to control them, with us providing activity sheets, reference cards, and helping out if they run into problems.more...
