Hey everyone, I wasn't quite sure where to post this, but since it involves TEK's and extra power supplies, I guess here is a good place.
I am making a water chiller, that uses 2 110 watt pelts, and 2 really crappy 300 watt power supplies to power them.
To turn the power supplies on I want to build a bit of a switch that I can put on one of the molex connectors from my main PSU. I will connect this switch to the power wires from the cooler psu's (green and ground).
The idea is, you put voltage into the switch (ie turn on the main psu) and the resistance between the ground and power wire from the cooler psu's goes to zero, turning them on.
I could do this easily enough with a small sylinoid, but would prefer to keep things purly electronic. I don't really remember enough about working a transistor to make this switch, but I don't think it would be complicated at all.
Does anyone know how to make ths switch, or where I can find some decent information on how to? Thanks.
