Design should definitely not be all sitting at a desk behind a computer. This was a 3 hour design project that was the result of having to come up with a Christmas gift for a friend who has everything.
I had just finished rebuilding an old Schwinn Varsity bicycle to a single speed and was faced with a pile of parts.
I looked at the old stem shifters and a bottle opener popped into my head. I must have been thirsty.
