One of the major reasons I started my car computer project was that I knew I was going to have a ton of annoying, pain in the *** problems. I needed a summer project that would let me excersise problem solving skills.
These problems are the fun part of building a custom system. How satisfying would it really be if everything came right together installed no problem and worked first try?
I'm far more proud of my system now that I've beaten it into submission and forced it to do my bidding.
Remember, Obsticals are those frightening things you see when you take your eyes off your goal.
