On the launch pad. A correctly valued capacitor in parallel with the 12 volt power source.

The "H" bridge cube magnets are too strong. The oscillator started up but I was slow in turning the power down and the magnet stuck to one side and shorted out and nearly started an electrcal fire. I reduced the PM strength on the traveller. You can see the axial magnet traveller stop short of sticking in this short video :

Damage from the "H" bridge short circuit :

The switchs are seperated in this configuration and should reciprocate with the "H" bridge connection. The first design was too clumsy. This one is much more elegant.

This configuration simplyfys the build. The problem is that a sticking magnet will cause a direct short.

I first coupled the switchs back to back. Now they are end to end. Same wireing as the first one. This is a far superior build with the Electro-magnets flat on their backs.

The bottom electrodes soldered together forming a Siamese twin frame fuseing the switchs. This is now a DPDT switch. Pushing one side up then the other is just like toggleing a current reversing DPDT toggle switch.

Here the top electrodes are double wrapped for reinforcement. This switch is now held together very strongly. A length of wire is added for the Potentiometer connection. I plan to wire a 5 amp fuse between the power source and the Potentiometer.

Look at this Capacitor bank used by George Chianotakis to loop his 12 volt Plasma Generator💯 6 of these puppies!

This is the same 2 spst limit switch current reversing "H" bridge circuit:

This is the second time I made the same stupid mistake. The electrodes are in a different place on the SPDT switch? Too much nutmeg.

My builds factor down to the very minimum. Here's another example of 2 complimentary paint stir sticks and 2 tiny but thick rubber bands: I soldered a 7 amp fuse and holder with in and out wires to the Potentiometer.
