3x 12v outputs doesn't need to be more than 30w per channel that can be controlled from 0v-12v to control 2 pc fans and 12v heat pad (the heat pad only draws about 10w)
1x 12v output with at least 120w maybe 150w max draw for a Peltier unit
6x Temp sensor inputs I have the probes already
5x 12v on/off switch controlled from the touch screen
A touch screen thats a decent size maybe around the size of an Iphone 4 or 5.
Needs to run on 12v computer power supply
