Mains to 12 volt supply needed, but what type?

[GRW]

L

But keep in mind it is DC not AC.

That doesn't stop those with pacemakers being advised not to work on car HT Lead Ignitions in case of shock.
You do get one hell of a belt off a modern ignition coil.

Connect it to the battery. Trickle charge battery.

I'd do the above but id buy a electric fence driver. Not worth the fallout if it hurts someone.

Whatever source of 12-ish volts DC you use, it will not make an ignition coil produce high voltage without something that is going to periodically interrupt the current flow in the primary - i.e. a contact breaker thingy.
EDIT
Yes, adding a capacitor across the contact breaker will increase the output voltage, just like it does on a car engine.

I am aprecuating your guidence.
Not just in the wiring of the circuit? What is meant by across the contact breaker?

I can recall the kick from one of the HT leads on my car late 70s early 80s. Just the hand. Points in them days were common, as opposed to electronic ignitions.

This thread describes how to rig up an ignition coil when you don't have an actual distributor & contact breaker:

ignition coil driver

for the radial, i need a booster boil as the on starting the impulse mags dont generate a strong enough spark to start the engine. you can get dedicated booster coil set ups for around 100 quid, but you can also use an ignition coil off a car. now im no electrical genius, all i know is i need...

See post #34 for the capacitor wired in parallel across the contact points.

A old school one will, a tickle charger will not have the amps you need for that project.
Many of us use chargers to power our rust removal tanks.
I have a few old school battey chargers here actually, I now use a PC PSU to power my rust removal tank

I use an old school charger but it only draws about 1/2 amp. What does your psu manage to draw. I use the rusty water to kill the moss on my drive and my neighbour’s flat roofs instead of pouring it away. It usually kills it for a couple of years.

The draw for me depends on how strong I make the solution. I have had it up to 6 amps before with a strongish solution and bake calipers in the tank.

Great idea about using the rusty water as a moss killer, I would not have thought of that now I know what I will be doing next time.

6 amp! I’ve got an old PSU so I’ll be trying that. I’ll post a picture up of how it kills the moss, before and after.

My tank is a old CWST with 6 brake discs init as the sacrifical anode or wait is it cathode I forget! I take it the moss turns black and dies like with the lawn teatment stuff that contains some kind of iron.

I think it's been mentioned but you would need something to interrupt the 12v supply to the coil for it to produce an HT spark (like a set of points does in an old car). Bear in mind also that your intended victim would need to provide a path to earth in order to get a belt off the fence and a squirrel would soon learn to jump up over (or straight on to) any fence or cage.

That would be very entertaining to watch from the house. I cannot tell if it was real

Same as that but northernly cheaper lad. (I’m from the south but it must have rubbed off when driving through Birmingham at some point.

Make it a bit of a challenge for them, some ideas here ..

@aesmith
Thank you for putting that clip up-interesting.

I got the impression that this guy is very creative and never still. Hence, here is the link to his other stuff. Thank you.

I had a very nasty kick off an electric fence many years ago. In the Brecon Beacons. No signs up. Not a normal looking electric fence either. My mate grabbed it and couldn't let go. I had to kick him off it. Reported it and the farmer was prosecuted. Turns out he had taken a feed straight off a 10,000v transmission line Only reason we weren't killed is that the fence was miles and miles long and had so many leaks to Earth. I think he actually went to jail as we weren't the only people who had been zapped.

 

[mart]

Good job you were there, to save your mate. Farmer sounds like lunatic.

A lot of them are.
Living on their own too long.
One of the highest suicide rates apparently.

If it was connected to an 11kV line (How did he connect it there in the first place?) then its verrrrry unlikely you would be here typing this now....and I'd also be surprised there was any fence wire left if it was down to earth anywhere
