    Hi edalatish!
    Thank you for your interest! I have added a hand-made wiring diagram with more details on the wiring, it's one of the versions we used to assemble the circuit. It's been a while, I hope that was the final version!

    Hi stevenblaine!
    Thanks for you interest and apologies for the very late reply.
    1. Yes the PID controller is the Arduino itself, it reads the current temperature from the temperature sensor, and adjusts the heating/cooling power delivered to the heating/cooling units through a digital potentiometer.
    2. It is an Antec A40 Pro CPU Cooler. We machined a small block of copper (see set of photos in Figure 3) to make it flat on all sides, and made some tapped holes to attach the cooler to the copper block. For the heatpipes, we drilled blind holes in the copper block to match the diameter of the heatpipes to a tight tolerance (within 0.2-0.5mm), then filled the holes with thermal paste and inserted the heatpipes. Given the tight tolerance the heatpipes didn't need any adhesive to keep them in place, but with a larger tolerance one could use some thermal epoxy glue to fix them in position.
