My little patch of the web to log my various electronics and other "making things" projects. Likely to involve electronics, pen plotter art and drawing machines, software projects, and photography.

Say hello

I'm occasionally on Mastodon @kristian@alwaysplottingsomething.com and Instagram @alwaysplottingsomething.

I'll be at Electromagnetic Field 2026. If I finish my Hexpansion projects on time, I will offer them in the day market as well.

Current projects

• Bottleship: a concept for a mood light made with a few hundred tiny LEDs on flexible PCBs held in a glass bottle
• Matrix hexpansion adapter: an add-on platform and breakout board for the Electromagnetic Field Tildagon badge, using cheap CH32V003/006 microcontrollers to drive many LEDs
• Donglegon: a USB device to use such hexpansions without the badge and control them from a computer or phone
• Pick and place machine: an attempt at building and configuring a small PCB assembly machine from old 3D printer parts
