Most controllers use a 78L05 linear regulator for the 5v supply. If overloaded, they can overheat and shut off. After some cooling, it can come back on. It could be just a bad regulator chip, but usually there is something else that's drawing too much power.
The hall sensors should draw something like 10mA or less (not exactly sure).
The whole controller on standby should draw less than 100mA.

dnmun wrote:my impression was that he had put an led on the hall sensor wire and it blinked. i was not aware he had ever measured the voltage on the hall sensor wire as the hall sensor was turned on and off by the magnets.
