Don't forget an appropriately rated fuse, especially if powered directly from a battery.

Good evening Hoppy.

It appears that your advice was perhaps a little too late for dear From other Planet !!

However we need to find out what is basically overloading the drive circuit ?? We now have got two prototypes that have burned out. Do we have, dare I say OVERUNITY ?? A rising out of control event ??
A scope would be of great help whilst testing this circuit so a runaway could be avoided.

Keep up the great work Guy's !!

Cheers Grum.

Hi all,

I've been studying the 494 IC.  Here is a link to the datasheet.

Dear All.

Short video showing how the manipulation of the air gap alters the output waveform.

Let's see if we can improve to a ring up ??

Cheers Grum.

Then I maked this divice for me burned many shotkys and not shotkyes diodes who in schematic is MBR, but I use others. Nothing other are burned. I burn about 5-7 in that places diodes. Burn and UF5404, who 400 volts and if good remeber UF5408, who 1000 volts, then ajusting, maybe, in small frenquency. So can bay many shotkeys diodes 10 amps 35-50 volts.
