GADGET!

it is nice to see you
hope you make your way ..  if there is anything i can help you with i will

as you all know my work leads to EL ie HEALING .. 

perhaps ill clue you in ...  if we have growen ...

regards  wish your little one well for me

You could start by an apology ...

all

i bought me some fugi cameras the other day to mod while i wait on my other stuff to get here and it was wasted money..
both cameras have the same layout but will not light the cfl's.. so i will be tearing them down to fix the transformers..
i was giving you guys a heads up if anyone buys them..
so try to find the old ones that have the neon bulbs in them.. the new ones have a small red led..
i draw the schematic of the first half of the new fugi camera circuit if anyone wants it..
hope it helps

Try this Kodak Funsaver mod. Real simple and works like a charm. Just hook the light in where he has his capacitor. 1.5 d.c. volts in. 450 a.c volts out.

Thank you for sharing that video.

Yeah, that is a slick way to get 450V.

has anyone been looking at resonance? i saw a pic of light and its resonance or half lifes. ill break it down.

if you broadcast a 3hz wave you get a half strenght wave at 6hz and a quarter strenght wave at 9 the life diminishes by half of the previous as the frequency doubles.

i compared these waves, the way the peak power over laps you would not want to set a reciever coil to the transmit frequency as that frequency will actually be hindered by its own transmission! and i know were not dealing with radio transmissions on this forum but i believe the same principle my apply to the joule thief although i havent had a osciliscope to test.

what it seems needs to be done then is a tank circuit set up on the joule thief to resonate at this higher 3rd wave the 9hz then the peaks of the 6 and 3 will better overlap in a way to have less cancelation.

of course the transmit wave carries the bulk of the power and thats why we still recieve some of the radio transmission but just think the second wave plus 3rd wave equals 75% and its frequencies are in just such a way that majority of their power acts against the primary wave!

on the other hand longitudinal waves dont suffer this and travel faster with +90% power transferred. i wonder if theres a way to use a solid state longitudinal wave?  back to google!

just wanted to share. if someone finds it interesting and wants to discuss yell at me
