Joule Thief

[Cap-Z-ro]

If you don't have any clothes pins, then I wouldn't advise hanging the clothes out on the line...especially if its real windy.

Alternatively I would recommend using a dryer and some smog scented fabric sheets...and your clothes will smell like they dried outdoors.

Hope this helps.

Regerds...

If you put the tubes next to each other in a U maybe you could get by with shorter jumper wires.

Made some tests on base of joule thief and coil oscillator to get up 20V from 1.5V.
To get a real results needa find a way to increase a current.

@ Light:

Nice work there.  Great pics.  I agree, More power is always good.


@ xee2:

That's a good idea but I have plenty of wire, the length is not my problem, I just don't have enough alligator clips.  I am thinking about using some aluminum foil rolled up to make small connectors.

@ Cap:

I have found that if you hook your car's exhaust to the dryer vent you can get that "outdoor" smell into your clothes easily.  I don't do it very often, only for special occasions.

Well, I gave it a go with the three tubes, 2, 48" and 1, 18".  I made some connectors out of solid copper wire that seemed to work ok.  This attempt failed.  I got the 2 48's lit but could only get the far end of the 18 to light up, and this would only happen when my hand was on the tube.  I used two strong neos to "pull" the light but, I could not get it to light the last tube more than about 25% of the length.

I have not given up, but will have to think of something else to try.  As Freezer said, maybe we hit the limit of these circuits as they are now.  If this turns out to be true I still think it is impressive to light these long tubes with a single AA.  The good news is that even after about 10 minutes of run time while I was attempting different configurations, the transistor and the transformer did not even get warm.  Oh well, some more things to think about.
