Isn’t there some trauma concerning the µCs that Andy won’t run on low-voltage ones?
As far as I understand it, if with the modification Lexel has proposed, the driver proves to be capable of running Anduril, the worry about needing extra time or money to make it 1.5V and 3.7V compatible is moot.
If the desire is to get an Anduril 14500 light as soon as possible, I think that can be accomplished already using a Texas Avenger design (I don’t know if Texas Ace sells them assembled, but Lexel has a variant) if you have a host that accepts a 15mm driver and are comfortable doing a driver swap.
To my recollection, Anduril is designed for the ATTiny microcontrollers, which require a higher voltage to run. The last discussion I saw was that the microcontroller would have to receive boosted voltage from AA/NiMH just to turn on, and then it could do its thing. Implementation of that (or another) solution is over my head
Interested.
Lexel has two coils on his board. It appears one drives the logic circuitry while the other drives the power LED. The coil that drives the logic circuitry can boost independently of the LED coil. Because the logic circuitry requires so much less current to run vs. the primary LED, the microcontroller will have power right up until the very end of the battery life. The primary LED may not be able to run, but the brains of the operation will get the juice it requires.
Count me in. Thanks
I suggest smooth diamond or square knurling for the body instead of currently rought,will be more nice to hold and simple ramping version similar sp36s
I guess it is now a matter of honour and glory to get Andúril in that thing.
Interested. I want that candle mode.
I would be interested in this.
Interested in one please

Interested! A choice for a rich deep blue color (ala C01S) would be esp. appreciated. 
interested as long as its anduril “1”. no anduril “2”
Interested but depends on final version
I’m definitely interested.

Interested. Hope for an update on the project soon!
