  To find the best place to connect the outside earth ground, just try it on different point on the circuit, and watch which point gives the best increased output brightness on the bulb. I place my ground connection on the transistor metal body on both the 2n3055, or the MJE 3055T (TIP 3055).

Try putting the earth ground at the Anode of the LED / coil connection!! Then touch this with your fingers and also touch the case (collector) of the 2n2222 !!
But I'm still not finding HV, and wherever I hook up the scope ground lead it messes up the behaviour and it acts very differently if I hook up the earth ground or not. Maybe my coil isn't right.

Great, neat, tidy little package and presentation. No Birds nests there! (think rose LOL)

Thanks.... There seem to be two things all electronic FE circuits need: batteries, and alligator clipleads.

Hi,

I did test a diode bridge in my circuit today. The circuit did use 3 Volt @ 0,02 Ampere before I soldered the bridge in the circuit.
After I soldered the bridge in the circuit, the circuit did use 3 Volt @ 0,12 Ampere and the LED lamp was dimmer. First test was
from a mains power supply. When I did connect the earth ground, then the current went down to 0,02 Ampere again and the display
on the power supply did start to flicker some random numbers. The light in the LED lamp was dim but did flicker. I then did run
the circuit from a 3 Volt battery (two AA in series). The lamp was dim and it was no effect to be seen when I put earth ground
on the output wires. I did try both wires. So there was no effect when run on batteries but some strange coupling effect between
the mains ground at the power supply and the earth ground at the circuit. I was not able to duplicate the effect LaserSaber did
show in his video.

Wow, things are moving so fast here, its hard to keep up.

I really like the idea of lighting an LED with your hands though, now how about lighting a CFL from a potato?

Alex ,I noticed something strange with the original circuit . if i take the base/secondary connection of the bulb and jump that connection to one of the primary side the out put increases . Mine is so strong i used my neon screwin base bulb and a cfl on that connection ..  . Warning i used only 1.2 volts ..My e core buzzes when i do that .i am uploading that short demo .. batt was 1.290 
i am pretty sure he has more that a 20/200 ratio more like 70/700 because as think as that transformer is he is using there has got to be a lot of windings. we found that to be true on teh ls3 rod projects . Also my ecore has 5 layers of #36 tesla wire about 3000 turns and 15 turns of bell wire or hook up wire and it's core is smaller . I do not think that is an ecore he is using . The transformer is the Variable here
