@all

Interesting effect of neo on joule thief from Kubikup http://www.youtube.com/watch?v=xvJzbcv2nac&feature=channel_page , This guy should be joining us. Ok he uses 12 volts on this one but a really imaginative gentleman .

Great video!  Yes, I hope he does join us.  I used a neo many, many pages ago to increase the output from my JT circuit. (I was just pointing this out for the record.)  I believe IST did this also.  This was how I got my first two 48" tubes to light fully.

@ Jeanna:

Just got back from work a bit ago.  Heck, I bought all of my 400 led Christmas lights for less than $18.00.  If I had waited until after Christmas, I could have obtained all strings of 100 for about $3.00 ea 100.

Now I have to go back and read all of the many posts I missed.

Yup, I know. I almost backed out, but then I looked around and they are really the cheapest around. Buying just the lights is over $1 a piece, and the place where I got the ones I used 30 of in my array doesn't show them anymore, but they were $18 for 50 of them. sheesh (to quote gadgetmall) So, I paid 15 for 70 with diffusers. they will light my house for years. I already have 3 strings in 3 rooms. so, fine.

I have a question about the string.

Do I need to short the plug ends to make it work?

I wasn't able to light my string with the secondary off my regular jt last week, and I am wondering what direction to go.

I have just finished one with 5+11 primary and 120 secondary. I can cut off the 11 down to 5 after the test if it doesn't work well, but I am wondering if the shorting the plug wires is the key to what will make this work? I don't remember if you got your strings to light with a regular jt or just the fuji. I nearly blew my led string with the fuji, so I won't go there again.

I still need to strip the varnish off the secondary. I will  in the morning.

Welcome back.

Jeanna:

I only shorted the plug to perform the one wire experiment.  The Christmas lights are set for ac so, you can hook up your wires without any worry about polarity.  That is what I did in all of my videos.  It made no difference.

Trust me on your led price.  I know what you mean.  I was paying like $2.25/led at my radio shack!!!!!!  So, when I could get 100 for $12.00, I jumped at it.  Then, the price kept going down.  I almost did not buy my last 100 (total of 400) until I saw they were under three bucks!  I love the free market.  I got a thing in the mail today (which I tossed) that said i could buy an led light bulb, for a limited time only, that has 10 superbright leds on it, and replace my incandescent bulb, for only.....$69.95!!!!!!  Holy crap!!!  I can make 10 light bulbs for that much and they will be brighter due to the JT circuits.

@Pirate

Yes ist did , first and must has inspired many to try, This one shows it on a scope http://www.youtube.com/watch?v=vjJ4Pk5OrDU&feature=channel_page.


I only got the idea of adding a Pickup coil, That is my part (page 21), but i don't feel the need to remind everyone, but then bedini did it first like the magnet part, now we just know what we are dealing with.

Everyone is needed !

Thank, again for the great topic!
