Add basic scale/voltmeter to TK35

[Artem]

Hi all,

I am thinking of modding my TK35 by adding a sort of smallish scale/indication of current charge level/voltage.

Something along the lines of those small strips on the side of Duracell AA primaries which you can press and see the approx charge level.

Preferably has to be waterproof and simple as.

Has anyone done anything like it or maybe can point out some components I could use?

Thanks!

Your volt meter is built in.

When the light drops out of turbo mode, not the 25 min safety mode it is time to change the battery. Or you go from high to turbo and the light immediately drops back to high it is time to change the battery.

Wow I didn't know it has this elaborate logic built-in, thanks!
