Question Peltier (TEC) from C@$!0 XJ-A1*0 projector

trying to start a new project and am having trouble finding info on the TEC used in the projector.
searched and have seen people use them at 5V@12.5W (or 2.5A) but i dont know if this was accurate (title was "semi-ghetto peltier-cooled handheld lab device" ???

anyone happen to know the voltage and amperage (or watts) that this uses????

any help is appreciated...

Default Re: Peltier (TEC) from Casio XJ-A130 projector

I drive them with constant current up to 2A, I don't know the limits.

P.S. You may want to edit the company name out of the post and title, they have caused legal issues for the forum in the past.

I don't recall, and I can't find where my peltiers are, sorry.

The LM317 diode driver set to 2A will work for this if you've got the parts

ive got tons of 317's and a couple of lm338 to drive it ~5A but to drive it efficiently, im trying to find the Vf for the TEC so all the extra voltage going into the regulator wont be converted into alot of heat.
