that the cfl bulb was not only not hot, it was ice cold...colder than my room temperature.

I would like to see you remove the Neo and see if it has the same effect. This reminds me of Sweets VTA and the tuning of the magnets on his cold electricity experiments.

i have bedinis that use this DIODE XEE#2

YES IT HAS A PORPOUS.... lol

Thanks. If it gets a big enough pulse to damage a 2N3055 then I would think it could be replaced with an LED and provide additional light. I have never used a diode there and I have never blown a 2N3055. But I never run off 12 volt battery or without a base resistor so maybe that is why I have not needed it.

EDIT: I assume it holds the base volt at about the turn on voltage of the transistor to make the transistor switch with lower changes in current through the base coil.

Hi
after night battary drop voltage from 1.274 to 1.271.
Im stoping this test for better adjustment

@all  I made a video last night and finally got it uploaded after 7 hours this is that JT that i built for paul but Gave it to Alex instead . MerryChristmas . This is exactly how i measured it and i have no idea why it put out more than in . Alex will have a good time with this one ! calculated just from My little experiment last night with his JT 5 mW in and 75 mW out, that is a COP = 15  No need to replicate  we have it under control !

@xee2
it is a little trick ...  i do reccomend people try it .. seamed to work well for me ..

i have 5w 1k ohm base resistors in place ...  with out the diode ... BANG POP BOOM ...  go your 3055's  try it ......  lol

i made a flash light mod video for everyone ...  you will enjoy ...  it is simple and will work in ALL LED FLASHLIGHTS as long as button is on bottom and case is alum

this is useing the ist 3 turn mini ...  all mods are contained in the battery holder it turns off and on all of it from the factory button .. in other flashlights i have done they require a wire or a 2nd switch ...   beat that annoying problem ... 

1 aaa and it is really bright ..

thank you
