Picap is a new product from Bare Conductive. It gives an easy way to connect up wires to your Raspberry Pi’s GPIO pins (via crocodile clips) and is designed to receive input from conductive sources. They sent me one recently, so I’ll be doing a review in a little while. Until then, here’s an example of it in use from Claire Garside. She’s used the Picap as a method for the family to choose which flavour of Quality Street sweet should’ve been replaced by something more tasty! Read a bit more about the project here.
