I have been waiting at least for 2 months for my sparky to come and put my controller together. I had most of the parts ready thanks to links provided in this forum. In the end, I gave up waiting for him, so I decided to put the thing together myself, with the use of the very helpful circuit diagram provided by punchy and yummy. I have some electronic hobbyist experience when I was a young kid (long ago 8-} ), so I really had the clear the cob webs and just took my time putting it all together. My idea was for a two channel/circuit controller operating in one box with a few extra helpful bits for me - which are revealed below :handgestures-thumbupleft:
I had to get some further parts locally like the box, din rail, flex etc. The little transformer is an old charger i had lying around which I broke open and hard soldered to wires to and from it.
A shot cutting out the front fascia - these were filed for a snug fit of the components
Start on the first circuit and 240 to 6 volt transformer

Earning it's keep, providing juice to "Apollo" ;-)
In case it not real clear on the last photo, the 4 temp sensors monitor the following:
top left - still
bottom left = boiler, via thermowell
top right = ambient temperature
bottom right - the internal temp of the controller
The controller is plugged into 2 independent 15 amp circuits which I had a different (someone that actually turned up) sparky install.
