also in the triple crown units there is a tip 47

http://www.datasheetarchive.com/TIP47-datasheet.html

this is  npn higher voltage ...  should make a  good modulator ...

if we can get the output to its working range and increase current to its working range ...

your set! i think we want to work within the transistor and diode limits ...  so as not to have any problems of things blowing up !

w

i did the pnp... too with MY WJT ... WORKS FINE AS SHOWEN ...  if you want to tap with the 5 feeds from trigger colpase ..  simply flip diodes ..

only mod to the npn is the flip of polarity ...

my next 3055 board will be 9 npn and 9 pnp ..

Hi guys anybody have bought a Ucap cause I'm trying to put a little charge in it and nothing is coming back  I tried a bedini motor to it but still no charge back.
Any help please?
Thanks

A bridge rectifier is used if the output is ac.  I dont believe you have ac coming out of the jt.

All JT circuits I've seen have AC. A bridge rectifier is not going to do it. Pulsed DC has both DC & AC. You'll need a filter to remove most of the AC.

You really need an oscilliscope to look at the type voltage you are putting out.They arent cheap so that is why I suggested the bulbs.  The incandescent bulb actually emits infrared emwave energy that stimulates argon gas into emitting visible light em waves.  But for true power readings you need to measure the magnetic field flux changes around the resistor also.  You can see how complicated this begins to get.  The argon gas doesnt convert all the infrared so now you need to do caloric analyses of the output also.

Or you can simplify it by using a super or ultra cap instead of a bulb, and suddenly your measurements become easy since it becomes all about DC measurements.

did i hear someone say we need a dubble 808 808 .....  OOOOWWWWEEEEE   DOGGGIE!

opposed triggreing ...  yikes ...  UFO!   LOL

IST'S D 808 G

LOVE YA !

H

YOU SEE THE KIDS WANTED ... me to have a ufo for christmas ...  thank you sky ali lauren and logan!

and now a PICTURE TO FIT THE OCCASION .. 

the SUN DISC!

you see i have a FEW POUNDS OF MU METAL...  anyone smelter ?   i need foil ... lol  then ill make MY SUN MIRROR ... LOL 

got the switches for my HOVER BOARD ....  GOT A TONNE OF SUN CIRCLES LOL ; )

I  can't say  I have the answer   but I may have part  if it.

When lighting  LEDs   with a JT  you  can  often light  them will  mostly  voltage  and  little  curent

I would  describe  this  as  " soft "  power.
Soft power  works great for LEDs but not so  good for  Ucaps.
With  soft power  you  light   the  LEDs  with voltage much higher than normal .
I have used up to 250V to light  an array  that   was originally  84V

I would  suggest  that you  you make  a LED array  for  the voltage you want to work with .
Tune  your circuit  to  light  the LED array at full  brightness  at NORMAL voltage ........that way you  will  be working  with normal power  not soft  power.

hope  this helps
