Thanks for your interest Mark. As previously stated I'm just getting into the electronics aspect, have done a fair bit of reading and some very low-level tinkering but that's the bit I'm most worried about messing up. Programming-wise I have a bit more experience, albeit rusty, did a 2-year degree in Comp Sci back in the day, never had anything to do with physical computing unfortunately. I'm certainly not looking to find someone to do all the work for me, just want to avoid making costly mistakes or wasting too much time on things that won't work!
