Nice idea, probably could but I do prefer set modes as opposed to variable output.
Taking this one apart has given me some ideas for future builds though
I do not understand everything that happens though, your pictures without words always make it quite a tough puzzle to work out eveything that is going on.
I thought pictures spoke a thousand words!
I know, I’m bad for that but it makes people think about it a little
I think I did the MT-G2 mod first then the other emitter swaps and then seeing what I could eventually pack into the tiny host.
I basically swapped resistor values, changed them around so the switch works the opposite way, upgraded everything and built in a lighted side switch.
Then I also added a tiny charger unit into the 10250 cell extension piece which also has the lighted momentary side switch. very useful that one.
So, the longer version ended up with built in charging and a momentary lighted side switch.
The copper version was a repair job & new emitter.
The short Ti version has a shortened rotary switch and GITD coated reflector.
