2013 Cool Joule is back – it self started !
And been running for the past 3 months, untouched.
This TinMan Cool Joule was built in April 2013. It ran for several months and was tested again shortly afterward. But for the last couple of years has been sat in the spare room.
In December, it fired up on its own again.

TinMan’s circuit diagram is shown at the start of the video.
