Welcome cyber traveler! You have entered the realm of Project FRAC: a DIY robotics hobby project. This site chronicles the journey of an electronics amateur who is building a pet robot from scratch, plus associated topics like electronics, embedded computing and maker culture.

FRAC prototype 1This project aims to popularize (amateur) robotics by showing that entry-level resources and materials are available and affordable to anyone. A secondary aim is just to showcase this cool little hobby and get feedback from and engagement with the community: your ideas, experiences and reactions are much appreciated! read more...

Exit Mac, enter Windows

Also, the camera unit needed to be turned 90 degrees to let the cable stick out the side of the robot’s head, so the head was disassembled as well. Anyway, here’s to the first time that FRAC is looking at itself! I have a feeling this might come in handy somehow…. read more...



This just goes to show how inexperienced I really am: during the weekend I was struggling with my too-short Raspberry Pi camera cable…
