You might want to add a 1M to 10M gate-source resistor, otherwise the MOSFET's gate can pick up noise, causing the LED to flicker and, to avoid damaging the gate from ESD, always touch the source side first, before the gate.

That's WHY I wrote NO Comment .. Its a Demo ONLY.
Personally I use a full Tester & or Curve Tracer Test :-+

Why post it, if you didn't want anyone to comment?
Another improvement to that circuit would be to replace the finger, with a switch. A small gate resistor, say 1k would also be a good idea, to avoid short circuiting the supply, if the MOSFET's gate is damaged. Also note that the gate-source voltage rating of some small, low gate threshold voltage, MOSFETs is under 12V.

If only you had a Brain and could Read the whole subject you would have realised why I put it there
But I guess you only want to add Stupid remarks that are not only off subject but are not relevant or helpful in any way .
The diagrams that were added are 100% operation and also allow for modification .
and Based on the Original Design . :-+
Have a good life, and go Patent some thing ..

I've merely suggested ways to improve the circuits you've posted, nothing personal. For the benifit of the orignal poster, here are some schematics illustrating them. Have a nice day.
