Last I checked, farming existed in all of the parts
of the UK, why not just buy a small fence charger?

They can be had for $50USD or so for a cheapy that will
easily do the job.

Anybody any design ideas for a high-voltage generator for an electric fence

garden and digging up the lawns?

I've toyed with adapting either a boiler/gas oven ignition system or a car
ignition system ...? But I'm lost as to determining what would be safe and
how to measure the voltage (kV), current (mA) and energy (Joules) available.

Any ideas or experience welcome...
