Hi,
I was researching DIY dew controllers when I came across this thread. I have a few questions I hope someone here can answer. I have two Kendrick heaters - one for the eyepiece and the other for my quickfinder. I may add a resister to heat the secondary mirror. I want to experiment with some baffling first to see if that is necessary. So I need a controller that can potentially handle the three dew prevention devices.
Would the circuit described by Al Sheehan on the projects page be OK to use with these heaters? I was also considering the RS components version Peter uses:

I was a little concerned about the posts relating to RF noise. Is this a problem with either of these controllers?
BTW I have a 12 inch computerised truss Dob (Mel Bartels stepper system).
Thanks,
Rod.
