DNA20D Tube Mod

[keighles]

Thanks for the thread info. My thought on the Teflon was about the same, but I was thinking of a ring that fits very snugly and would be hammered down into the tube to act as a stop for it.

That could work, I had the teflon so close in size. The cold was enough to shrink the aluminum to not let it fit. So just a slight change in the diameter of the tube should stop it from going anywhere.

Wow, a VV GG of sorts. Nice work.....

Can you shoot me links to the button you used? I'm drawing up the plans for a dual 26650 DNA20 box but I'm having trouble finding a switch that can handle as much current as the DNA20 will output :/

The switch doesn't have to be anything special. It just closes a logic circuit. The power for the atty from the batteries, to the board, then to the atty. The button doesn't take the brunt of it like a mechanical or "simple electrical" mod. From the data sheet:

Switch:
Use a momentary on, normally open type switch or button. A standard pushbutton switch is
appropriate. The switch is a logic function – all power switching is handled with transistors inside the
DNA module, so the switch does not need to be rated for power. A waterproof or processed sealed
switch is recommended.

By the way, love your reviews, keep it up!
