Hi!
This is how I did this.
This is a relay, this is a 9-volt battery
and these two transistors are connected in a Darlington way so that
even the resistance is very high in megaohms
the amplification is great enough to trip this relay to power this.
And the winding powering this is isolated from the power line
so I do not receive any electric shock because they are isolated that even I touch this and then
I don't receive in a shock at all
and I'm gonna show you the diagram on how I did this
but do not repeat what I did in this video and unless you know exactly what you're doing
because playing with electricity is dangerous and can kill.
You must also have a background of electronics to understand the schematic diagram.
This is the input and this is the output
and you're gonna plug the device like this.
And this is the trigger.
