Hello guys, I need to make an electric fence for my sheeps. Can you please help me and give me an easy method to make it?
Depending on where you are located you can find a lot of products to do this, for example, in the US:
But, in any case, the way to do it is to buy commercial products, the complexity of safety related things and all the details of a successful deployment make homebrew very dodgy unless you didn't have to ask this question.
The thick wool of the sheep likely prevents it from getting a shock.I have one, but it's too weak, that's why I want to make my own with a higher voltage output.
The one I have is also homemade, it uses an ignition coil and a relay. The power is generated from a 12v battery charger. It's pretty weak, my sheeps can play with itThe thick wool of the sheep likely prevents it from getting a shock.
There are a number of fencer designs (here) that use an ignition coil to generate a higher voltage than a typical fence charger.
The are generally safe if powered from a transformer supply or a battery, since an ignition coil can't generate a lethal amount of energy (otherwise there would be a lot of dead car mechanics).
Hello Eric,hi Selve,
Sheep are very difficult to 'shock' , all that wool and Lanolin.
Have you tried different settings for the relay Dwell time.?
I managed to get my design working with sheep OK, on our South African farm
Post you circuit diagram.
Hello Eric, sorry for the late answer and thank you for your diagrams.hi S,
I can see lots of problems with that fencer unit, it will never give you the high voltage required for a good electric fence.
This my circuit diagram.
Added an image of your circuit.
The highest voltage from that circuit is approx 10kVolt
