So how do you suggest cutting glass(quartz or pyrex) tubing yourself? If I knew it was easy I would have tried a long time ago

that's a good question... for flat glass we always used a glass cutter(it scored the glass, then you tapped it and it came apart) not sure how that would work with tubes....

these are also only 8mm thick, if we back to back them it would be only 16mm thick, @ 4400mAh, this would be some serious power and using the high C rated safe battery, this is the one, or I should say 2, now to find a wiring schematic seeing how to wire two of these back to back and setting up the USB circuit for this set up. This is purely awesome, this can be done I believe. Even one of these would be fine but 2 x is sick power and over the top, nothing could touch this power and it makes for one helluva APV

. Back to my fuel tank design table

Talk to your electrical buddy about a wiring schematic for this , using 2 of these like the Darwin does with a USB charging circuit see if you can get the schematic draw up for what we want to do, for me please, I will build this unit.

Just got home. Haven't been able to find the C rating of the HTC batt yet, though I emailed the supplier and asked if they had that info. Judging from all the stuff the HTC Evo can do/handle, and how fast the batteries die in those phones, I expect they just may do the trick. Little more research and I'll let you know.

Waiting for my buddy to email me back, but he probably is just getting home as well and doesn't answer non-work related crap when he's there...loser haha. I think those 2200mah batts would work perfectly! But I am unsure onn the safety of putting both in parallel, but placed back to back. I found this picture of how to wire the batts together, with the loose ends soldered to the 5 and 6 spots on the DNA. The page I saw this picture at warns that placing two batts in parallel is unsafe though, although lower down it states that they are safe if they "are assembled by a company that is experienced and certified to test and assemble battery packs. The individual batteries are tested and sorted by machine so that each pack has matching batteries with the same capacity and internal resistance. Individuals do not have this equipment, which is why you should not try to make your own packs."

It could possibly work if you set up the tube on something to allow it to spin but not move side to side, and the glass cutter was stationary (or rigged stationary)
Just my

though, no technical knowledge of cutting glass here, just decorating it.

glass tube cutting - YouTube this is how you cut glass tubing.....

Holy cow....just caught up. I don't see the advantage of a quartz tank...quartz is much more fragile than borosilicate. My dog has tummy troubles so I am off to clean up some surprises he left me while I was at work today :-(

good video Ferris... pretty much exactly the same as flat glass.. I figured it would be harder than that LOL

Be careful, I have seen many a glass blower cut his thumb open doing this, and we practice it every day.

I'll tell you what. If you can all come up with a standard inner diameter I will cut, polish, and anneal a bunch of free tank tubes. Let's vote...what inner diameter would be the most useful? In mm please :-)
