Kapanadze Cousin - DALLY FREE ENERGY

   Perhaps Hoppy has run out of fakes to deal with. The asylum is getting low on new fake devices, so he may out of the streets looking for some more to put to the magnifier test.

Hi all. I'm still around taking the medication. The streets are too dangerous for us inmates, so I've stayed in the asylum watching the Punch & Judy show on TV, with those fake BREXIT politicians messing up in the other asylum called Parliament.  Any news of a true self runner on the horizon??

Really?? Better asylum than here??

Yes I understood your point. Sync looks the same as important as everything else in this device.
About arduino, it is just an alternative idea for sync. I will upload sketch if someone is interesting to experiment with, but after testing it first to see that it's working.

Here is a self-oscillating add on driver board with overcurrent protection.
I built it as a test rig add on for obvious reasons
If i was building from scratch I wouldn't do any of it like this.
It does work with excellent driver waveform.
The feedback circuit trips when the Fet Sauce current produces  0.8v to trigger the SCR
some of the fates are used to indicate the Led to show over current trip fed from the UCC
pin 3.

You don't have to use that part of the circuit it will still work

Great job. A circuit diagram would help a lot though.

This should help pin 8 of the 74hc 00 drives the diode as a fast switch
Note I used 1.67mhz here  don't assume that's a relevant frequency.
