Bill,

Your going to have to hook that 5 gallon water bottle to a balloon and set it free. Then watch the news and see how many UFO reports you get.

Yes, that would be fun.  I added a top to it and more leds and then, remembered that I had some fiber optic material and added that to the very top and it looks very cool.  I still have not added the Fuji JT to it yet but, I know it will work and I can set it outside and it will run for hours on a "dead" battery.  It sort of looks like a robot now, ha ha.

   @Bill:
   That jug does look cool.  How long do you think a single AA will keep 200 leds lit? 
    No problem with the waves here in Costa Rica, yet.   Should make it here by 4:40 pm.   I live about one foot above high tide level.
   
     @Mk1:  I belief this 2012 thing to be a Universal event, and not just with a single planet affecting our local solar system. Time will tell.

  The biggest solar flare in years had no affect here. Nor do I suspect that this event today will affect us here. 
   Hopefully there won't be more earthquakes in the next couple of days.

Nick:

I am not totally sure but I believe from experience that a "dead" AA bat. will run this for probably 4 hours or more.

   Bill: 
   What will the jug do with a new AA, in duration.  Using the 5 for a buck toroids?  I'd really like to know. Even a guess will do.
   The reason that I ask is because several people have mentioned that there is little or no additional load when running many leds off of the secondary coil circuit, compared to the primary on a Jtc. 
  My experience shows that there is a much shorter run cycle with an increased number of Leds, even when they are on the secondary coil output. 
  So, what then, would be the best combination when using  a single AA battery as input, for best light intensity (no. of Leds?)  as well as best duration times.

NickZ:

I really don't know if I could make a JT with a 5 for $1 toroid that would run these 200 leds.  I believe Jeanna and some others were able to do this as you said using multiple secondaries, which I think we now refer to as pick-up coils.  I am making a very small Modified Fuji circuit to run this jug and will have it so it can run off a wall socket or any sized 1.5 volt battery.
As we know, the Fuji is not known for its super efficiency so battery life with this device may not be much longer than 6-10 hours with a new batt. (AA)  Of course, a C or D bat. would last longer.

Thank you Wilby and Bill, it seems that I have a Kodak board looking at those pics you sent...will be making a modified JT as soon as time permits, and hope that it will run some decent lighting with my 25v EB's

Thanks Guys
