I've talked with this guy on the phone a long time ago. If it's the guy I'm thinking about he was early at RIM, cashed out, and has been doing stuff like this for years. He clearly does it because he's an engineer's engineer, he's doing it for the sheer joy of building things. Super fun guy (and I'm a woodworking guy, not as clever as him but I can appreciate what he does).
