Joule Thief

@ Gadgetmall:

Thank you for the info.  I will try to get some readings in about a week or so.

I agree 100% with what you are saying here.  As far as "competition" goes, I like to look at things that way as it spurs me on to try to do better, or bigger, or more...or like you...with less.  It is all friendly anyway.  We are all on the same team here as far as I am concerned.

Now that I know how to check the power draw, I will also go back and replicate my breadboard JT's (I have 4 versions as of this time) and see what they are pulling also.  And yes, if someone lights a tube with a "standard" JT circuit, that would be something for sure.  Thanks again.


@ Freezer:

Nice video and great job!!! (5 stars)  If you can light a neon, do you think it will light a 4 watt tube?

@ IST:

Good job on your video as well.  (I gave you 5 stars as well)  Keep up your great work here.

Any one try running two joule thiefs on one transistor?

I tried it and it seems to run twice as fast.
As they both trigger each other.

Here's a circuit for it.

Another great video. Thanks. Is the coil air core? If the fluorescent tube won't light with 1.5 volts try 3.0 volts. It looks like your components will take 3 volts and that would show how close you are (I think tube will light with 3 volts).

How many turns on coil?
