Attiny 25V running Bistro HD OTSM
OTSM works perfectly with lighted tail cap and hot light no more OTC timing issues
2S Bistro OTSM now on all sizes but 15mm available, 15mm 1S OTSM implemented with design change
or
Attiny 85 running NarsilM v1.2 with latest version with fixed bugs
Narsil manual , a lot options to configure this one
NarsilM driver can be thermal calibrated as well
you can choose the temperature for step-down, but change it later in User Settings

how it began can be read here
each generation adds more features
Generation 1 is now available for D4, High/low capability but then LEDs dim to about 50% between full and empty battery
LVP can be added for 0.7€
Generation 2 2 groups of LEDs or rainbow added voltage stabilisation
2.8V 18uA LDO used to keep brightness stable down to about 3V battery voltage
trimmer optional
Generation 3 2 groups and low battery LED (s) added low battery warning and LVP
lights up with constant brightness

Annoyed with the low output with remote pressure switches for flashlight?

I did a board with a MOSFET to eliminate the extra resistance from the external switch
size 16-17mm, for 16mm the battery holder fins need to be cut a bit

If you want just one mode in direct drive you don’t need a driver in the head

I use a MOSFET with a low gate voltage which gets full output down to 1.8V

The MOSFET is powered by a CR1225 Lithium battery with 36mAh should r…
Based on Generation 1 2 channels with optional trimmer for D1, D1S can’t fit trimmers
[image] [image]
any color combinations are possible each LED could have a different color
D1(S) based on 20mm Noctigon board
2 options
direct light here the LEDs get placed next to the main LED
board is best to sand as thin as possible, and sand the LED gasket the same amount to stay in focus
[Emisar D1 with D4S genes]
- indirect light shining on the Gasket (not tested yet)
LEDs as you wis…
if you found a fitting board just PM me
its designed to fit the original charging board
