nice, but never use it with battery - the relay and the LEDs will suck it down within a short time. The protective effect is also just working, when there is a very low-ohm fault (shortcut), do not feel too safe because if the fault current does not fall below the tripping threshold of the relay, current will continue to flow into the faulty load. Also, and most importantly, the relay lacks a free-wheeling (fly-back) diode - sensitive loads could be destroyed by the high voltage spikes created when the relay drops out.

Thank you Sir. Note to other geeks, You can buy 12v relays at a auto junk yard, newer cars have several in the same place as the fuses. Small black enclosure under the hood. I bought 40 for 20 bucks American. Some of then have output contacts rated at 30 amps or more.
you should of put them in your pocket and got the five finger discount. hell hang out at the appliance and computer recycling place. I get all kinds of good stuff. thanks John Poodle.
Very nice, except for ONE FATAL FLAW: the "no power" LED (RED) and relay coil will KILL A ** BATTERY ** in Very Short Order. Therefore, it's best used with a "wall wart" or similar AC-powered DC power supply.
Интересная схемка, получается что питание нагрузки является питанием солиноида самого реле, тогда чтоб поставить нормальную нагрузку, надо и реле ВООООТ ТАКОЙ мощности!?
indeed. another bonus feature with using relay is during a short circuit at the output, it would rob off the energizing current to coil, so it will turn-off(cut off output power).
La desventaja que le veo a este circuito es que cada vez que ocurre un cortocircuito franco, se va deteriorando el contacto normalmente abierto del rele (NA) hasta que termina de fundirse cuando de le hallan dado varias operaciones.
Hallo saya pernah membuat alat seperti itu sama persis,tapi untuk pemakaian beban besar sangat merepotkan contoh dynamo 12v saya pakai alat itu dan langsung jeklek ke led merah.. Tidak bisa menyala led hijau,selalu led merah,tapi kalau di beri beban ringan normal lancar lancar saja..
If you added another switch to the other pin on the relay you would then have a on and off buttons on the board. Then you don't need to short it to turn it off. 🤨
@@Inventor_AW You are in fact shorting the power supply to release the relay coil. A crude, brute force approach. A more traditional way to create a SR latch is with two switches and two transistors. The relay output is optional. You can make this using just the relay and two switches but one of the switches needs to be NC (normally closed) and wired in series with the relay coil. A significant limitation of this self-piloted design is that the relay coil voltage must be the same as the load voltage so why not just use a maintained switch instead of a superfluous control circuit. If you're interested in this type of thing, why not build a transistor toggle latch circuit and a transistor SR latch circuit to drive your relay but keep the relay contacts isolated from the control circuit so you can use it for any supply and load voltage the contacts are rated for.

How much of the current capacity of the supply is used up by the relay coil?
sorry ?
If you added another switch to the other pin on the relay you would then have a on and off buttons on the board. Then you don't need to short it to turn it off. 🤨
i don't short it to turn off , I explain : it's Anti short
@@Inventor_AW still using the other pin would be a more practical way to turn off what ever your powering.
If otherwise please explain.
