Making a mini fridge. How many peltier units do i need?
I want to make a mini fridge rather than spend the $80-100 for one. I wanna make it 3'x2'x2'. How many peltier units would i need and do i need heatsinks for both sides (hot and cold)? Also do i need a converter to change the 120v down to something the peltier units can handle?
