This my second TEA laser, and although it isn't the best, it's still pretty cool. I have a video of it firing, and if I shot at a black piece of paper for minute or two, it would actually make a hole! It took me about 30 minutes to build and a couple hours to adjust the spark gap...

Bump, I need help. I changed the di electric to overhead projector film and although it's not arcing through, it has still yet to laze.

Sorry to be pushy, but bump

It began arcing through the di-electric.

bump.

i got it working for about 5 seconds and then it stopped and I can't get it back

FBT driver is a 2n3773. Yeah, I did post on 4hv. It just doesn't seem like anyone knows how to fix this. I have found several people who have had the same problem, but none of them have been able to fix it. I got the firing rate pretty stable using a resistor, but no lazing at all.

The dielectric is 4 sheets of .05millimeter paint-drop cloth, the capacitor plates are aluminum foil, the electrode is a s are aluminum v angle stock, and the power supply is a 2n3773 flyback driver. The electrod rails are readily firing but just not lasing. I have tried just about every rail...
