Here is an easy to duplicate circuit without bifilar coils that will light a fluorescent tube for 4 min and 20 sec from 20,000 uF capacitor charged to 12 volts. It should light tube for about 9 minutes with a 40,000 uF capacitor. Tube is not full bright, but is bright enough that it can be seen without turning off all the lights. This is just a basic Joule thief circuit with the resistor and capacitor values selected for run time. I am still not sure how LaserSaber is getting the bifilar coils to work so I am looking forward to his next video. Current drain of this circuit is 0.53 mA when 20,000 uF capacitor is at 6 volts.

EDIT: I have tried using 2N2219 and MPSA06 and neither of them worked in this circuit. It may be that it will only work with the components specified.
Also, oscilation may not start if input voltage is increased slowly, charge capacitor before connecting to circuit.

I went back to the germaniun diodes and I should have a true replication as soon as I get the 10,000 uf caps. This things works like an "Exciter" now and is great fun. I don't think that my run time will ever be very long but this was an enjoyable project and worth doing.
(sorry, lame sense of humor) We received our germaniums yesterday. That was it for the self-run on our build, we had a nice light going for 15 minutes. When powered w/ 6 volts, and an even brighter light when started w/ 12 volts – so heck why not – we slapped it w/ 24 and poof – let the smoke out
That was our last fuji transistor. Could not get it going w/ anything else we had lying around. May have shorted the fuji transformer as well. We were using the cap resister in place of the germaniums and could get it to run nicely, but no self run.
