J  what diode do u use ?

xee#@ diode ?   

this plays a large roll 

USE THE DB 107 BRIDGE ...  1000V 1 A

I BOUGHT 500 OF EM ....

i have had super results ...  i will try them on the cam boards ... 

1 cam i get 350v plus ac ...  at 7ma

2 14 ma

12 

over 800v 150 ma + ac ontop of it !!!!!!!! 

: )

In your quest to charge caps...

Actually my quest is really to get some warmth happening in the cfl so it can glow as bright as when it is plugged into the wall.

I have gathered that pushing the charge by means of the cap will get the cfl going when still unmodified. If I can get it to work unmodified, I believe it will glow brighter.

And, as far as the filament bulbs go, xee2 and wilby are the only ones I remember doing this with a jt.
xee2 has used kooler's circuit, and wilby did not answer when I asked him, but heairbear was over that evening so...

thanks; any ideas on this?
Have you managed to light a filament bulb or a cfl unmodified with your jtc's?

Please share if so.

thank you,

jeanna

I used a 1000v 1A 1N4007
and a
Hi voltage ceramic cap 105 = 1uF

I did not use a bridge.

I do not believe xee2 was telling me to use a bridge.

thank you,

first off your useing your ring right ... from the secondary ? 

if so use a bridge and cap and your cap sux

lol

try the ones i showed rectangle   ac ~ caps

my cam boards are neg flyback cap tapped  and rectified fly back .. ...   ring is INDEPENDENT! 

some common ground some common pos .... 

i have many boards wired many ways ...


hope this helps ... 

there better diodes too  try a switching one ... 914 i think    or a crystal one ...  i dont know the part # 

but there weird looking ones

those gave best results ...  also ... your making your ring SING ....  you will never get it to work properly ...

you must tune it just after you can no longer hear it ...  for best cap chargeing results ... 

i fear your coil is not tuned for such use ... 

the wjt  is like your singing coil ...  but better results for caps are atained when it is silent!!



scope it ...  you will see ...

loggie does a surprise visit .. says dont forget thermal escape pod too ! 


that little fella!   

lol

love the magic...
