New uses for old circuits.......but not as intended

After testing the Pummer circuit in a Solaroller I now know why you don't see them:because it doesn't work.What happens is that the Solaroller moves forwards and backwards with each "pumm",and while this makes for interesting behaviour it won't win you any Solaroller contests.
So,I'm keeping the one,already finished,one but added a LED which doesn't pumm but flashes,making a mobile LED flasher.
The others will be finished with the normal solar-engine circuits.

New uses for old circuits

This last weekend I had a revelation......(scary)It occured to me,while I was building a Pummer circuit,that the circuit could also be used for other non-LED projects.Like movement(probably done before)and in a Solaroller(maybe not done before).
So I started making three Solarollers with Pummer circuits,each with a different capacitor and one or two of them will be using Wilf Rigters improved Pummer circuit.
Now all we need is some sun.........

The big project is finished(or has been since a few days)and I have finished a smaller project as well:the industrial looking one with a valve and gauge.
The valve I found at work,the gauge came from my favourite antique place,add to that some copper pipe,old brass fittings and various metal pieces I saved in the past.
