@all
I saw on TV a chappy who got hold of a dozen empty 2ltr lemonade clear plastic bottles, filled them with water, drilled holes in his shed roof, and shuved them halfway through the roof.
The sun shone on them, and from inside they lit up very brightly.

Must try this soon. better the power money in my pocket than in others.

hi folks    i'd just like to say great thread and great work everyone. Ive been having a mess about with a jt - i havent got much in the way of torroids except this big one (4.2" outside diameter 2x120v inputs and 2x7.5 volts outputs) a few wires to mess with hehe. ive had over a hundred leds running nearly full brightness on this setup but the draw varies greatly from 120 milliamps and it will run down to 30 milliamps just lighting the leds. currently i have paralelled 2 duracells which have run this rig for 3 days solid near full brightness but heres the twist - on the 3rd day i decided to try and feedback some juice to source so i put a germanium diode from the base of my bd139 tranny back to the negative rail, i got up this morning and there was no light but the current draw showed 12.3 milliamps this morning - ive let it go on to die totally but it seems to be recharging back up slowly by itself (16.7ma currently) i'm waiting to see if it will get back up to light the leds again. maybe not good results just as a basic jt but this feedback thing is interesting. going to keep an eye on this. ill try and get some pics soon - i'm on a light a room on one aa campaign now hehe!

take care guys and gals and keep up the good work - catchya soon - eel

there 2 transformers in every cam unit ... as i have seen


the second is the little one that goes to the flash...

vcr motors ROCK   they are designed from inside out!!!!!   hummm

think it makes a diff???  lol

they could and can be used many ways ...

so you dont think i can top the fugi with a homemade jt...   i know this is wrong ...

AS THE FUGI IS BUILT WRONG 

I HAVE SAID THIS LONG TIME AGO ... IT NEEDS TO BE TUNED ....  MORE THAN JUST CAP RES AND COIL ...

but walk the path you  have choosen

no wonder ...  lol

i only was useing the transfiormer ....   no doubt you can light cfls so bright ... unless i missunderstand you

you are useing BOTH TRANSFORMERS......  LOL

ist!

if it can be done with the cam it can be done on the jt   thing is we wind our jt ... lol it can be wound to SWITCH CURRENT.......  WHERE THE FUGI CANNOT...

what will be if .... you switch current

I thought thats what we are Doing on the MK2
