Peltier Voltage control Answered
I have a broken TEC wine cooler that I am converting into a temp controlled humidor. The MOSFET on the control board blew up so I was able to buy it for $9. I am adding humidity control and I want to log so I am going to control it with a raspberry pi. A Arduino would do but I want to program it in python and will have it host its own site to view data logging or to send failure alert.
The wine cooler was rated at 70w, I'm not sure what the Peltier is rated but I am assuming less then that @ 12v. I did some tests with a bench PSU to see what it will draw at various voltages up to 8v (the max my psu goes)
