DIY dew controller

As we get later into Autumn it is becoming obvious that dew control is going to become necessary for my telescopes. To do that for all my OTAs would be quite expensive, so I looked around and found Robert Brown’s open source “myDewControllerPro” project that looks as though it might be quite a practical solution.

I ordered some PCBs which have arrived. Now I need to wait for parts to arrive and I can start soldering.
