No worries. I'll just make one using his instructions or buy a ready made one. The only thing that threw me for a loop is that the 7805 regulator provides 1.5 amps but that must be enough? The 5V regulators seem to be a common item and they are about $20 on Amazon. I might even stop at the electronics store today and see what they have. Its a cool store....not sure how long it will be around.
