The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

My guess is that 20 would do it. I will solder them up and work out how to string them nicely. A linear string is interesting but there are potentially a lot more creative ways to arrange fluoros around a TC. Looks like rain this week end though so might be a bit limited in what I can try.

like writing your name in flourescant tubes. that would make a great avatar!

Here's 30 with no problems even with a dead tube. I didn't have very strong rope so it is supported in the middle via a convenient branch. The termination near my sign is fortuitous.

Very cool project. It looks very pretty in all the pictures. Is there a reason why the arc has to travel through air before going through the fluoro string? I also like the sign in the last picture.

The reason is that there is a cetain breakout voltage with the topload, because of the capacitance, and that makes it so that it will have a larger ability to light more tubes. When attaching metal directly to the topload, it works as a breakout point, and lets the electrons out at a lower potential, due to lower capacitance. This means that you would end up with fewer tubes being lit.

From an earlier post...

If you simply connect it to the end of the TC it will be seriously detuned. I have used breakout points for past projects up to perhaps 30 feet long which reaches the limit of my tuning on either coil. Then there is the cumulative corona loss.

OK. No-one has posted but it is 48 hours and I have new info - so I qualify for a legal double post.
A rearrangement of the string using about 19 of the tubes. Sort of dwarfs me and the TC. Note the rounding of the picture at the corners with the limit of my wide angle lens.
ps I have more photos for this and the "Mother of all LED's" thread. Back to the old days going full steam ahead on multiple projects. Ain't antidepressants wonderful.

TC driving Fluoro string. How long?
