Beta of the electron eater!

This is (I think) the final design to be made into the production model. Everything in flouro green (including the red and purple count wheels) has been altered because of design shortcomings discovered with the 1st prototype!
The red and purple count wheels went to the dentist to have their teeth reshaped so that the the backstop and pulling arm (respectively) fell into the wheels, not leaving a recess for backlash to occur. (see top right and bottom left yellow bits)

The face no longer supports the centre shafts, as it created too much friction of there was a small amount of twist in the clocks chassis. The new face design looks better too!

There have been 2 lobes added to the cam wheel (above), to make a total of 3 lobes. This will make the impulsing circuit energise the coil every 10 seconds, instead of every 30 seconds. I think that should be enough to keep it running. Only a long run like for an hour or 2 will tell, and I am yet to install the 3 lobe cam into the 1st prototype to see how it goes. Here is what the 1st proto type currently looks like...

I don't like the all black, it was just easier to cut all of the pieces in one cut. When this was first assembled, I wasn't feeling that is was going to all that successful. With the new mods made to the design, I am really confident that its going to run well! Fingers crossed.

LATEST UPDATE...
I think I am going to try a Mercury Switch!

Here is a design that could work. The mercury switch is the spaceship looking thing mid left. The long arm on the lever is to amplify the small lobe on the on the cam. We'll see
