The Stirling Cooler has been running fine for a couple of months now. Power consumption is around 600mA most of the time. I intend to improve ventilation around the box which will hopefully lower the consumption even more.

It has five temperature settings from 10 deg C (too warm) to deep freeze. I use the second fridge setting. I'm thinking of buying a second one to use as a freezer.

PS. The first generation of these were apparently rather noisy. Mine is audible, but no problem and I'm a noise sensitive person.
