Hi there, I'm Markus – aka Max Siebenschläfer 👋
Maker · Mechatronics engineer · Industrial engineering student
I build things that blink, move, weigh, cut and count – mostly with an ESP32, a 3D printer and far too many ideas at once.
- M.Sc. student in Industrial Engineering (Wirtschaftsingenieurwesen) at THM – B.Sc. in Mechatronics
- Makerspace person at heart: workshops on mold making, cutting plotters & more with OpenA5
- 3D printing & publishing designs on Printables – robot arms, gadgets, organizers and tiny deck boxes
- Embedded projects with ESP32 / ESP8266, Arduino & Raspberry Pi – displays, sensors, stepper motors, web interfaces
- Always happy to collaborate with other makers and content creators
