touch-activated LED driver, or close proximity activated.

you could use this very simple circuit to detect electrostatic charges.


the entire circuit is nothing more than 4 NPN's in a Darlington configuration with the Base attached to the tin.

something interesting im just noticing is that i can walk anywhere in the room and the light will switch on and off whenever i lift or set my shoe to the carpet lol.. so its able to pickup a charge from a good distance..

this is how the SEC works.. it takes the very tiny charge that gets amplified by a transistor and runs it through a HV transformer. when u touch one of the antennas with your hand it switches the tranny and completes a potential circuit through the air.

neat man.. can you post all the parts and values used ?

@nja2015 no need, its just 4 NPN transistors in a Darlington arrangement, thats all.. and as a matter of fact they are 4 different models too.. doesnt matter.. 2n2222 or similar will work fine, some may work better.

the main Base is touching the tin. the transistors work to amplify each other so very little static is needed to switch it. i have one resistor of unknown value limiting current into the circuit but that isnt needed.

nice work magneticitist.

Interesting!
