Hi, this is my first post and my first question.
I have no knowledge in electronics so I am looking for some kind of a “kit” that I can buy to build a dew heater controller. I saw this article
http://www.iceinspace.com.au/63-285-0-0-1-0.html but that kit is not longer available (I can’t find it anywhere) so maybe someone out there has another option. My power source is a 12V 7.5A sealed battery and I need 4 outputs (eyepieces, red dot view finder, green laser and maybe my secondary mirror in a near future)
Regards
