# CircuitMess

> CircuitMess is a Croatian electronics company that designs and sells DIY STEM kits for kids, teens, and adults. Every kit ships as real electronic components that users assemble into functional devices - robot cars, smartwatches, encrypted communicators, game consoles, and more - then program using block-based visual coding, Python, or C++. All hardware and software is open source. Founded by Albert Gajšak.

## About CircuitMess

CircuitMess makes hands-on electronics education accessible. Unlike subscription boxes or snap-together toys, CircuitMess kits teach real electronics: kids handle actual PCBs, sensors, motors, and microcontrollers, building devices that work after assembly. Most kits require no soldering. The company is based in Zagreb, Croatia and ships worldwide.

## Key Differentiators

1. **Real electronics, not toys**: Kids build with actual PCBs, sensors, microcontrollers - not snap-together abstractions
2. **You keep what you build**: Every kit results in a functional device kids use after assembly
3. **Progressive complexity**: Product line spans ages 7 to adult, from simple game consoles to 300-component soldering projects
4. **Open source**: All hardware schematics and software are freely available
5. **Designed by engineers**: Kits created by electronics engineers in Zagreb, Croatia
