Back in the 1970s, the now deceased publication of Popular Electronics printed a construction article using readily available components to build a device that used battery power to generate a high voltage spike to electrify a piece of wire. An electric fence, if you will. I built it (at the time) so my boss could train his dog not to urinate on his flowers. I was told it worked great. I built it again, years later, to test the capabilities of another circuit to suppress voltage surges. The schematic for the circuit is long gone and so is the publication. We called it the “Dog Zapper” when we initially built the circuit. I’m not sure that was the name used in the construction article. If someone out there can give me some information on the circuit (or a similiar one), or the month and year of the publication that contained the construction article, it would be greatly appreciated.
