I suppose your herd of incontinent goats helps a lot there.

Neat idea,Sir Cumference wrote:A door electromagnet connected to daisy chained timers would be the safest option I think.
I would think if you could not lift 180kg which I guess would roughly be the weight of two average sized people then you wouldn't be able to pull a mag lock rated at 180kg apart. But if you are supergirl type, then you might need something stronger. but I think you should be ok with 180kg.Annabel wrote:I like the idea of stocks with a mag lock. You wouldn't need to go crazy with the mag lock strength. Do you think a 180kg holding force should be enough?
I think being able to pull the cable out is a bit of a double edged sword, It might make a good safety escape route, but it might also be dangerous. You might not pull the wires clear of the connection and this could cause a short and a fire or a shock. Even if you tied pulling the plug out the socket by pulling on the cable it might only pull the wires from the plugs connections. To prevent that you could fix the cable fast in the stocks with a cable clamp like you see in a UK plug. At the plug end you could have two hooks mounted somewhere on the wall or a solid object and then wrap the cable around these hooks, only once, giving a secure fixing, if you want to be double sure its secure use cable ties, zip ties, to hold it in place. This would stop the cables being pulled out but you have to have some form of safety escape somewhere.Annabel wrote:The drawback to this would be the weak point to where the power is delivered to the stocks. I imagine you could just hop away until the power was yanked out.
there's no problem getting a suitable battery. Best bet is a 12volt gel cell, you can get these in capacities from about 1Amp-Hour to 100AH plus ! and you can use a cheap car battery charger provided it is suitable for gel cells (they have different charging requirements to the usual car battery with open cells)Annabel wrote:

You'd have to secure the stocks to something. I'm working on a design for some mag lock operated stocks. Using a 180kg holding force mag lock powered by 12 volts 360ma supply. It will be likely mains powered but if I can power this using a battery I could incorporate it into the stock housing.
Not sure if I can get this battery power though nor how long it would keep it powered. Not to familiar with that kind of stuff. Waiting for the battery to flatten before release does sound kinda fun though but going from that Duracell bunny advert I'd be in them till doomsday
If you are trying to work out how long a battery will last for a certain circuit it is not so easy. To calculate it, as far as I remember, you need to use an equation called the Peukerts formula you also need to know the amp-hours Ah rating of your battery, the battery voltage and the amount of power (watts) being drawn by your circuit.Annabel wrote:As mentioned my understanding of batteries isn't too great. For a 12v 360 ma mag lock, could I use a battery that delivers 12v but more than the listed milliamps. For example it says 360ma but could I use a 12 v battery with 2300ma and the lock would only draw 360ma or is that not the way it works?
