relatively easy, and would involve more physical work than design.
However, the peltier power supply section would have to be designed from
the ground up. However, our task is simplified in that a pelt is a solid
state device, and does not need a sophisticated and perfectly clean
voltage waveform in order to operate. Therefore, I decided upon a
classic DC power supply that was based on an AC transformer with a
rectifier bridge and capacitor for smoothing. Here’s the simple
