Electronics Peltier question

would this work?

considering i have a powerfull enough power supply for like a 112 watt pelt? and yes i know i need a heatsink to cool the hot side... this isnt for a computer im making a drink cooler

 

yah, but it will suck, it will shorten the peltiers life span considerably, you'll want something with the ability to control wattage going to the pelt.

 

how would i do that?

 

You have it going to the +5V line, so the pelt will be pretty underpowered, unless its a 5v pelt of course.

 

so if i connect the red wire to the yellow 12v it would work? and then get something to regulate the voltage going to the pelt?

 

killer paint skills (sorry, i had to say it)

 

Use a high power transistor and a potentiometer set up as a voltage follower. Then you can vary between 0V and about 11.5V (Transistor loss)
