I built myself a cnc router of my own design. I constrained myself to a footprint of just one square foot and was able to create a fairly capable machine.
FourThirty mk.1
I’ve been wearing my MSP430 watch pretty regularly. It proved to be a practical timepiece, so I figured I’d have a go at a new version with some upgraded components.
Robot Rebuild
I recently rebuilt my previous OpenWRT based robot. Focused primarily on reducing its size, I replaced the bulky L298 motor driver with a much more appropriate DRV8833. Redesigning the pan-tilt mechanism, and replacing the MSP430 with a more compact ARM Cortex board further reduced the robots size.
OpenWrt Robot
I built a robot around a TL-WR703n router running openWRT. Client interface written in jquery. Video is streamed to the client via mjpg-streamer. Commands are sent from the router to a msp430 controlling pan/tilt servos and motor driver.
OLED Watch
After finding this neat organic led display, I decided to make a watch. I’ve used a msp430 with a cr2016 coin cell.
