Rain and Electric Fences

Due to poor weather we couldn't work outdoors so I used this 'opportunity' to assemble the circuit board for our soon to be electric fence. I am building the electric fence from scratch as the commercial systems are just too expensive considering what they contain and do.
I am using a 12V car battery with the circuit board pictured above(tiny isn't it?) to drive an old car ignition coil. It has a variable pulse rate and costs in total around 15% the cost of a commercial energiser. You can obtain plans for this and other handy circuits at Chemelec. The plans are all free and as an additional service Gary provides kits for most of his designs.
