I would definitely be interested in something like this. Currently an engineering student who's messed around with FPGAs, microprocessors, assembly, circuits and the like. I find that getting good, clear and concise info for these more hardware-related pursuits is very difficult. Oftentimes I'm trying to get through an incredibly dense manual or just googling through forums of people with similar problems.
Not sure how much I could contribute but I could always share my experiences thus far. I would be an interested consumer for whatever you're doing with respect to hardware startup info though.
