@Jeanna

I only have 2 types of diodes for use. they are
4001 - (I made a full bridge out of these.)
and 4007 -(just got them)

L jeanna

Here is some info for you and I'm sure the others here will be interrested and jot this down.

I bought 100 x 1N5408 diodes, from Jaycar cat number ZR1017. (came in a plastic bag)
These are rated at 1Kv at 3Amps, it cost me $16.95 australian, so they should be about $8 USA.

EDIT I should have included these are the same type as the 1N4004 x 1kv diodes which are rated as 1Amp, if you put 3 1N4004's in parallel, you get a 1N5408.


I want these later on when we manage to get further along the track when our EB or JT are putting out grunt.

@All

Problems with slow connections and Videos
Gary I know exactly where you are coming from, I still have slow dialup.

I  have not seen  the  video  of your  bedini .......or any of the other  videos here  lately

I have to make  do  with a very slow connection  right now .
It is so slow that  this site  usually times out  once or twice  before I get a page to load .
Videos are out of the  question .

I do  know that I am missing alot  because  I can't  watch the videos .
That is just the way it is .

Gary, to make my part more enjoyable here I make a small videos with my mobile phone, I put it to the smallest 640x??? image it can go, then make a video, but I have to stop recording the file when it size gets to about 240kb. So 12seconds is my limit.
This is because Stefan has only alowed 250 Kb as an image file Max size.
To post the video file, I click on the Browse button, tell it to go fetch and click on the post button.

I also find it difficult to download these big video files from YouTube, so this was my way to help those who have slow download speeds.

Hope this helped you

Gary i have Dial up also . It sucks . BUT one thinkg i do have is a Moto q Cell phone with unlimited web on it . I simply bluetooth  it to the big computer and have high speed that way without all the extra cost . Its only 10 dollars extra for unlimited web access on my carrier . I use the cell phone for high speed dialup . Its better . you got a bluetooth phone . all you need is unlimited web and 20 dollar bluetooth dongle for your computer . and a little bit of hacking I love the old moto q . there is every application out there for free . It runs windows mobil and has internet explorer and opera browsers . email Tv radio video camera . all the messengers like yahoo chat and voice .  It does everything . I did buy a few programs and i recommend a program called kinoma . . has tv and radio and audio books and lots of media  including youtube ,orb and about 15 other services all rolled up into one nice app . It nice to watch The Invaders while your waiting at the doctors office or just doing nothing . . or better yet log on the forum or watch youtube 
@NOp i don't get free energy from My Tv or phone line . I thought this is conversation was about undiscovered uses for ac to produce power . Yes ? not a known multiplexing and known radio or microwave signal. what happens when you mix several signals on a tpu ? I'll tell ya  . It frys your TV and your phone! Why ? HOW ?  This is what i'm talking about that they don't teach you , you have to do it outside the Box and learn it . I hope i never know it all . I love learning about the Unknown and there is plenty left .

I had dial-up for years and years.  I finally found that I could get DSL (the slowest speed) for $10/month and I was paying $12/month for dial-up!!!!!!!  I got it and, watched a bunch of videos on youtube and learned a little bit.  I can now download at 950 kpbs!!!!!!!  This is faster than a friend of mine's DSL and he is paying for high speed at $50/month.  I run speed tests every now and then and it is still doing well.  if I ever had to go back to dial-up, i would probably throw my computer out of the window.

Great info Gadget!!!  It just proves, where there is a will, there is a way.

Bill      PS  I am not doing anything illegal, I only tweaked some things on my computer and browser to allow them to work together better.

OK here is what helps.

Now I understand those among us who seem to always have the 104k cap in parallel to the base resistor.

I wound another primary and got the BJTL to go on with
4TB,11TC,(I have a temporary pickup of 10 turns.)

So, the toroid needs 4T,11T to turn on the led and have it be bright enough. I started to remove some of the 11T from the collector coil and the amps draw started up and the light got dimmer. egads! I started with 11T of each and went down; maybe I should add more than 11 to the collector coil.

The 10T pickup is producing 2.12V but ONLY if I have the 104k cap parallel to the base resistor and the light is in there.
If I pull out the BJTLed, the volts off the secondary go DOWN to 1.8v !!

The frequency is 1.4MHz

I guess I got my high frequency.
