making a small batch of Texas Avenger "TA" Drivers fully tested running Bistro or Narsil, Clicky or E-switch, SIR800

Just little more Narsil update news -

  • no further progress yet - project juggling
  • looks like the new BLF GT buck driver that's in the design/proto phase will be a perfect fit for this combined Narsil version - I'm calling it NarsilM for now: Multi-channel configuration
  • the GT buck driver will just be another channel configuration, but with some special needs. Two I/O PWM pins, but slightly different behavior
  • I'm a big fan of the TA triple drivers, so I want/need to get this done!! (as I hit myself over the head...)

You will need to add a resistor inline with the LED in this case or it will drain the battery very quickly. A normal through hole resistor could be used easy enough. Something around 30k-50k ohms generally works out ok.

Are you guys talk'n bout a tail bleeder LED (Bistro - clicky) or locator LED w/Narsil? For Narsil I use somewhere between 2K and 15K, depends on the LED(s) and visibility of the LED.

Well, it sounds like he is talking about installing an indicator LED using the tailcap bleeder pads.

So it would remain on 24/7 and drain the battery continually. 50k ohm resistor tends to have the final output be around ~0.050ma from my testing, so a little over 1ma per day of drain.

I want to use the Narsil option to activate/desactivate the locator LED, not simply use a bleeder resistor + LED :slight_smile:

This makes more sense and it also means you don’t need a resistor, or at least as big of one. But in this case you can’t use the bleeder resistor pads. I am not sure what pads you need to use but I think the voltage divider pads. Never used an indicator LED with narsil before myself.

Ooops, removed this post. Lexel is using an older version of NarsilTriple, so not sure about the Indicator LED support.

What would you recommend for a broken thorfire s70s driver?

The TA30 was designed for the L6 and S70. I love it in my L6 although it can get really hot if you run it on turbo.

I’m not sure what aplication X3 is using.

I was talking about a side switch led for the L6, not tail switch.

I don’t know much about the “indicator” or “locator” led. My plan was simply to have the side switch light up whenever the tail switch was turned on.

When not using the light I will click the tail switch off which cuts all power.

I want LVP, so I got Lexel to install Narsil v1.2.

BTW, I have a 1.45 milliamp drain on one of my drivers. Is that considered high? It has had zero effect on battery life so it doesn’t seem to be a big deal.

Narsil is wayyyy lower, after you wait 10 secs or so from turn OFF. Did you wait long enough? In the newer versions it's reduced to 5 seconds or so.

It should be 0.021 mA without R1/R2. If you are using R1/R2, depends on what values you use. I typically use 192K and 47K - 10X less drain for the old resistor values, so resulting drain is 0.038 mA.

1.45 mA is like 38X greater.

I was asking about an FX-30 driver I’m using.

Also, what kind of drain do you get from a zener modded driver?

the locator LED/sideswitch LED can be used with tailswitch lights without a problem, that was its main purpose

for lights with no tailswitch a locator LED should have a pretty high resistor, like Texas_Ace wrote to get low parasitic drain, you can still get brighter that trits with parasitic drain af a few 100uA

My drivers arrived today, they look very nice.

Thank you for doing this, can’t wait to put them in to use.

EDIT : Just finished putting one of the drivers in a Skilhunt H02, re-flowed the original emitter to a Noctigon MCPCB, the UI is great with lots of options and the ramping is fast and smooth.

It get very hot very fast :smiley:

My driver arrived today, and is already in his pretty host : Nitecore HC30
What a wonderful UI ! I love the ramping, really intuitive, and fast at the same time !
Thank you very much once again Lexel !

Received mine today, as well, that was quicker than expected, thanks.

Thank you Lexel, received the drivers Tuesday!

Excellent work :slight_smile:

Got mine installed & working. Convoy L6, inspite of discovering my led is in backwards (reverse polarity).

Still trying to figure out how to get ramping to continue in the same direction. It seems to want to change directions.

Edit: nevermind about ramp direction, got it now.

Also, can I switch it from initially coming on at turbo with rear clicky, to the 2 blinks?

Thanks

Is this normal?
