I am also starting to create a circuit using the exact peltiers. We are trying to develop a way for people to commuicate with heat. I also have very limited electronics but I do have the peltiers in my hand and I am eager to get them working. I thought it was as simple as hooking up a battery but I read in this post about PWM circuit using a 555 timer and a power MOSFET and I am a little hesitant to just hook them up now. Any information for a beginner would be appreciated. I will continue to look back at this post and share any good info I find...trent
