Paul Brown has another kickstarter up, this one is for a controller board for neo-pixel LED's.
The basic cost is £6 per board, which covers a controller chip, extended GPIO header and header pins for connecting the LEDs.
A power supply for the LEDs is not included.

Apart from the obvious of a Pi, soldering iron and solder, you will need to source your own power supply and own neopixels as its something i wont be able to get cheap as I will get hit with huge import and custom charges for ordering in huge amounts which would mean passing it on to yourselves thus why I am pointing you to where to find them.
Please read all about the project on my blog including links for demo code.
