A NEW REVISED PCB & PICTURE OVERLAY.

A Simple design based on a 555 to Drive a Car Ignition Coil.


I Designed this for a Small Electric Fence to Protect my
Vegitable Garden from some Small Animal called a Marmots.
Last year they ate one of my crops entirely before I could
install this device.
A Few Shocks and No More Probem.

My Garden is on Raised beds and the High Voltage wire is just
3 inches above the wood frames on homemade PVC Pipe Insulators.

Could be Quite useful for persons that have Rabbit Problems also,
with the wire raised a bit higher, But Read Warning Below.

Definately Makes a STRONG Electric Fence.

However, because it is a Continuous pulse output,
WARNING: This can Kill Smaller animals,
such as cats and rabbits, And Probably Even Small Children!


For a Much Safer Electric Fence,
PLEASE consider making the  "C-Mos Fencer" Project.

However this Car coil design can have many other uses as a HV Supply.

Not much else I can say now, maybe more later.


An Etched and drilled PCB's is available.
