Yippeeeeee.
I went into Ballarat today with my budget of $27 (all I had), and spent about 45 mins at Dork Smiths.
I came out with all the gear I needed to build my Heater and Fan control system . . . with change!!!!
Yep, the whole lot only cost me $24!!!!
I spent the next 2 hours building it.
I am no electronics person, and this was complicated. But I nutted it out with a bit of common sense, and all works perfectly.
Oh, and Gary will be pleased to know I built a Fuse into it
It is outside right now on the scope running the 2 heater strips I made.
Its cold & dewy out there and no dew on the lenses yet
Thanks to everyone that assisted with info to help me
