Recently got a codebug board from the kickstarter.

For those that don't know, codebug is a cheap (£10) board with a 5x5 LED array, 2 buttons and 4 GPIO,

and it's programmed with a visual block based language direct on a web page:

Here I made a very simple codebug rover using 2 continuous servos on an old boe-bot chassis

The servos are powered by 4x AA batteries:

and codebug's 2 GPIO pins are connected to the servo control wires.

There's no servo control library, so I'm bitbanging the pins.

A pulse every 19-20ms with the length of the pulse dictating the servo position:

Since they're continuous rotation servos, one extreme postion is clockwise, the other extreme anti-clockwise rotation.

A smaller version, with 9g micro servos and a lipo battery:

And for fun I just strapped a pager motor onto a bare codebug:
