this is my new approach to prevent dew on my 8" SCT, and it worked twice so far. Comments welcome!

I already have 12v on my helmet for my bluetooth headset.

It's a very good idea!!

@Danny: my battery is 7 Ah, we'd use 50% of the capacity. In my case the heater draws 0.25 A. 3.5 Ah / 0.25 A = 14 hours.
My next thought is to take off the dovetail bar and place the cable tie base below it to make the setup look much nicer.

Only worry I would have in this setup is the resistive wire breaking off after a while, at the height of the connector.
