High Current 12 VDC Supply

This is a new power supply built from a transformer and rectifier (mounted on the aluminum heat sink) taken out of an industrial control-timer of some kind. The black transformer is a heavy duty winding that appears to be rated at over 11amps on the secondary. In this first use, we were able to drive 8 amps through an electrolyte solution of sodium bicarbonate and sodium chloride in a new electrolysis cell with four aluminum bar electrodes. Of course we had to test for flammability....
