Hello, Oztules.
Congratulations to you for sharing so much with so many with generous passion, and to David, Dario, and tskamath for documenting your fence drivers for the benefit of many of others around the globe.
I have spent the last few nights reading this whole thread hoping to find the schematic for your original 12V DC board. Although I did find the 12V, DC, board PCB lay-out, unfortunately, it appears the schematic, with components names and values has not been posted (There is, of course, the 12V light version you kindly adjusted for Madlabs, which, in turn, was painstakinly documented and reproduced by David), but I have been unable to find the one corresponding to your original 12V, DC board, at full power. I've tried to draw it from the board lay-out, but I am not really good at it.
I am writing to you from Central Mexico, where crime rates are skyrocketing. Entire cities where a few years back was a pleasure living, are now becoming very unsafe, to say the least. I protect our home with a commercial electric wall top fence, 555 timer driven and car ingnition coil type powered. This is what you get here from dealers and installers. But robbers, rapists and other type of criminals are not stopped by these fences. These high impedance-powered fences are not a deterrent anymore. It appears to me that your 12V, DC driver is perfect for wall top, home protection. I don't think a robber would want to continue messing with a fence like this after a first shock from your "bull stopper", hanging from a ladder or jumping from roof to roof, especially if he has been properly warned with explicit high voltage signs, etc.
I would very much appreciate it if you would find a moment to scribble and post the schematic with components and values. I believe that is the only information missing, as you have explicitly and generously detailed the rest. Thanks a million in advance for your appreciated help.
Vic.
