Just rebuilt the 12V and 5V supplies on my TZ which has had intermittent reset issues for the time I've had it. The ezSBC,com LM7812 and LM323 are definitely the WAY TO GO!! Way more efficient, lower heat, and the ability to bias 5V a little higher (5.1V) fixed my reset issue. I'm also running a Prof. Pinball Pinduino to drive LED strings and a PinSound+, and it's rock solid. A+ product.
