That looks good Martin.

In your pictures, you have an actual temperature controller on the peltier. We did a quick test with a 30mm x 30mm peltier junction powered via a 12V to 5V buck converter. Under load it was actually at 4.88V. This was stuck with heat sink adhesive pads to an old 80486 CPU heat sink and fan. Running continuously attached to the camera, it simply stabilised at a temperature of around 26C on the sensor. This was with a not a particularly warm ambient temperature, probably around 14C. (We were capturing video with the camera as we normally would during this test.) The case of the camera was very cool to touch and there was no condensation. From this test it seems questionable whether it would ever reach a temperature needing to be turned off. Does your set up actually turn on and off in use, and if so, at what temperature on the probe attached to the case? Have you experienced any issues with vibration caused by the fan?

Thanks again.
