7400 competition entry: Peltier temperature controller

Posted on Friday, October 21st, 2011 in 7400 contest by DP

Michael entered a TEC temperature controller into the Open 7400 Logic Competition. Logic chips control the temperature of a thermoelectric Peltier element (TEC) heating/cooling plate.

Current temperature is measured via a sensor placed directly on the Peltier. The target temperature is set by an 8bit dip-switch. The circuit will cool or heat the Peltier until the goal temperature is met. Check out the circuit in action below.
