Custom hardware, simple software, real projects.

I build web things & hardware with small computers. With children of all ages as well as for industry.

Participants built & programmed their own game controllers from real components: ESP32-S3 (a microcomputer), buttons, joysticks & LEGO.

I visited David & Sebastian at SEOK to explore collaborations: they wanted programmable components & I wanted to learn electronics etc.

If you want a hardware workshop (project based learning), or need a pragmatic developer write karl@svartholm.com.
