Hi everyone. Im a very amateur hobbyist and this is my first post. Any help is appreciated. Im cleaning out the workshop of a local mad scientist. I know enough to identify his various components but I came across a box I cant identify. Its a grid of metal sandwiched between two pieces of ceramic with wires soldered on each side. Im thinking its some kind of inline heat sink or heat sensor. Anybody have any idea what the heck these are?

These are Peltier devices.

When a current is passed through them one side gets hot and the other cold. If you heat one side (or cool one side -- or both) you will generate a current.

I was hoping it was something like that. My vocation is computers, it will be fun experimenting with these on CPUs. Thank you!!
