Currently only does simple on/off on H-bridge.

### Webui

Simple webui with streaming webcam, motor control.

Nodejs with socket.io

## Hardware

### Controller

- [x] Raspberry Pi

- [x] Bypass poly fuses on raspberry pi

- [x] Atmega328 for Motor PWM and servo control.

### Motor driver

- [x] [L293D board](http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200982006661&ssPageName=ADME:L:OC:GB:3160) has been ordered.

### Motors

- [ ] Motors are crap, buy new ones? Steppers? geared DC?
