I am currently preparing to build the “Revised Millet-Hybrid” and intend to use the “TREAD” power supply at 24 Volts. I would like to use a relay triggered by a momentary contact switch for the “power on/off” switching. My question:
The “TREAD” board includes a provision for a LED to indicate “TREAD” power on. Could these connection points be used to drive the relay switching circuit? I am looking at using a 6 Volt relay and adjust the LED resistor to supply the voltage. The relay circuit would be controlled by a MC4069 IC chip and a 2N4401. Another option would be to tap into the AC voltage at test points 1, 3 on the “TREAD” board.
Thank you
