Ian was talking about actually building his sex toy at the weekend. Just to give him a headstart, I have managed to get hold of a spare PS2 controller (with vibrate function) from ebay. I have also located a programming guide for the PS2 (which does involve soft modding a PS2, of which we have access to 2), from PS2 DEV.
I do have a few ideas on what the software should ultimately do, but I will be happy just to get the vibration thing working to start off with.
Somehow I don’t think Sony are going to let us license this product….
