well

i finally found some fine turn pots... 15 turn 1k and 20k 15 turn also i found some trimmer caps 0-50pf 95-420   lol

so i may be able  to tune in the gadget mod now i sure hope so ...   

i only have 270ohm resistors for the invertor unit ...  i will build it with those first see how it works  out


ist

a few pics .....   tiny jt 6 pac

and  the invertor  2n3055 and  270 ohm resistor 5w

ok good all done the invertor now back to work on the solar light ...   the light stick ....  and the solar powered jt battery charger / cap charger ...


more pics as i finish the next units..   then the gadget mod .... 

oh i have a set of unfinished mag amps too lol   always a thing or 2 to do

on the light stick ... i was going to have the second transistor switch the aux cells and batteries on and for the cfl unit ...

and use the solar units as is  only to recharge the batteries the unit on the top will control both jt and cfl ...   but there is a problem where the transistor does not supply enough juice for the cam unit to operate ... there is lots of juce in the battery but  the transistor will not supply it

i think all i need to do to compleate that unit is find 1 that will handle the power ....

or finally get gadgets mod to work  ......  i have not had good luck with his mod as of yet ..  but im sure it is because i do not have the same transformer and switch ..

Heres an idea for your Switch using the circuit that comes with it plus an SCR
http://www.freepatentsonline.com/4581542.html

Also is this what you want ?12 ma Draw ?CFL ? CHEAP AA POWER ?? Look Close there is a Switch ! I use a lot of Switcheds this is just like My Kicker Switch on the SCR bedini . its a monetary push kicker. Adj lower than lit then FIRE ! .. Haha . I sound like you now been hanging around here too long . GEEEZZZ  .. i don't know what up with youtube but when the new video comes online have Close look at that FuGi .

wheres the video.... ??

didnt upload ?

@IST
maybe you already found yourself a switch transistor, but just in case.

3904 = 330 miliwatt
13001 = 600 miliwatt     <--in sunbeam 9 watt neon light

you might be lucky with some computer PS power transistor.
e13007, 2sc2625, both are 80 watts
c4242 is 40 watt
but i don't know the min trigger voltage for them.

i am still trying to find a 1 ~ 3 watts transistor, but have not got any lucky yet.



B.T.W. i think i previously took the wrong reading...
the circuit in the garden lights, both kind  = ~ 55 miliamp X 1.2 volts = 66 miliwatt
55 miliamps, not 270 miliamps as i previously stated.
sorry for any inconvenients that might have caused.

thank you

THENOP

that will help me and everyone for sure!!!!

here is the transistor number i found in the photo sencer unit at ramma..

xl 1225 08 d    it comes with a photo cell  for 1 buck i have not tested it yet or looked up the specks...
