The prototype is operational..
Here's a picture.
The rest of the album is here
The sales thread is now open here
A step at a time.. i only made it voltage regulate to 6.8V for starters because it is a bit tedious to get the current limiting working, but voila! it works just as designed!
Some bad news.. the space is exttreeeeemly tight.. i have to find out the length on the cells i'm going to procure but it might mean i can't do the swappable driver board.. i think that adds 1.8mm and that just won't fit.. I do have a backup plan to get another 1-2mm.. if it didn't bother you that the tailcap would not be screwed on as far (still both o-rings would seal and you would not see them, but when 'locked out' you would likely see the o-ring groove.
I have to work on other stuff for a bit, but expect to get the current limiting (so you can swap between HOLA and LOLA w/o changing settings)..
So i need to get some feedback for demand, also interest for the swappable battery pack (one driver, two packs, etc), so please take the poll.. pricing will depend a little bit on demand.. need some quantity discount for the metal machine work.
The pack will run the HOLA lamp for about 35 minutes, God only knows how long on the LOLA..... long.
Oh.. some might not like this.. but the button is FAR easier to operate.. you can have it near 'lockout' and it still takes a good throw and decent effort to turn on, but if you have it nearly locked on.. feather touch will turn on the lamp.
