This project is not quite dead. I haven't had the time to get back to it for way too long, but in the next few weeks I will be tinkering with it again. I have been flat-out with university, work and general life stuff, but I do want to have another look at this before I pack everything up and head off overseas. I have a new batch of PCBs on order, so as soon as they turn up I will be getting back to this. ;^)
