This, of course, generates a lot of heat and to mitigate that he’s added a Peltier cooler ... Developing a PCB is only one part of the equation; you need to etch it, too.

Peltier effect modules, also known as solid-state heat pumps, used to be exotic tech but are now quite common. They are actually the reverse of the Kelvin effect. Thermocouples exploit the Kelvin ...

"Measuring the coupled transport of electric charge and heat in the Peltier effect allows us to deduce the entropy, a ...
