Decided to make an electric slug fence yesterday, after my new
autumn crocus shoots got eaten for the second night in a row.

No slug damage this morning!

I was going to make a slug/snail electric fence for my new garden.
I already have a 12 volt DC supply nearby so I was intending to run
two bare copper wires about a quarter of an inch apart on the timber
around the garden. After reading this I will put a resistor in the
supply line!

My wife will be interested in this. But please explain to me what the
resistor is for? I'm sure my physics GCSE (grade B, 1988) will
stretch to me actually understanding it, but I can't bring enough pre-
existing knowledge to understand it on my own!! Also, why the LED?

Perhaps a full "how to build an electric slug fence" guide is
required?

THanks

Matt

maybe the design could be "tweaked" to kill the b*ggers rather than
merely put them off? or am i being dangerously over optimistic.....
