A blogger at PiecesOfPi.co.uk decided that he (or, indeed, she) wanted to build a GPIO board for themselves. So, they’ve taken a piece of stripboard, some LEDs and a few switches and done just that. He’s posted all the diagrams so you can replicate the board, although he hasn’t included much in the way of help with the software. Should be fairly easy to knock something up with Python or ScratchGPIO, though. Read all about it here.
