A blog about my tinkering with Arduino, ESP and Teensy microcontrollers. Besides developing physical and IoT prototypes, I like the challenge of coding math visualizations within the relatively limited specs of these boards.

This blog is currently in the (slow) process of being relaunched.

A selection from archived old posts will come back online, revised where necessary due to changes in libraries, APIs or the Arduino/ESP toolchain. Some new posts may be dedicated to the most ‘popular’ projects from my side trip to YouTube.

Latest project: Wireless Audio Visualizer

Music: “Golden Brown” (The Stranglers) performed by Karina Ramage
