The 2nd version of the power supply is finished. It also provides 8V to power the Cam86 to reduce the heat generated from the regulators on it.

See screenshots of the TEC power before and after the smoothing (the purple line in the 2nd image, ignore the other two).

However, this was tested with the camera opened and on the bench. The cold finger was not touching the back of the sensor. We are currently redesigning the housing to fit the new power supply only then we can do the proper tests with the assembled camera and take the bias images.

In other words without the power supply being attached to the camera I cannot be 100% sure that it will eliminate the noise. But this is probably as good as it will get.
