Tom's stopped selling boards & PICs now, but he's kindly left all you need to roll your own. You'll have to download the code & burn your own PICs & make your own PCBs too.
Aus is an awful long way to go for nuts... I got the pots from eBay, so nobody to go back to there. Even so I've tried all the UK dealers, RS, Farnell, Maplin, Rapid, no luck. Most vexing it is.
