DuaneJ1,The board is pinomelean's original board; it is unaltered. However, you need to solder two mercury switches to the board, which is really easy, and also use the modified software.If you like, I can send you a picture. It's alot easier than trying to explain. ;)Again, a BIG thanx to pinomelean for this rockin' instructable!
