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

[MrJohnny]

Hi I will take 1x 17mm Bistro long spring.

@Lexel

The 30mm 2S Narsil works with Eswitch and fits the L6

It can be used with Zener Mod, but you need to lock out the light because that has a quite high parasitic drain, the LDO reduces the parasitic drain so no lockout needed

Narsil can be modified so the light gets on at Turbo if you want to use the forward switch tactical, similar to Klarus XT series lights

Forgive my ignorance… I’m not sure what the pros/cons are of the various options. Basically I would like minimal parasitic drain, most efficient low and mid modes, Narsil ramping, and of course FET turbo.

What is your recommendation?

Also, can the tail switch be used for lockout?

Thank you for providing this service.

I’ll be in for two 17mm (short spring) with latest Narsil Triple, looks like Tom E just uploaded v1.4 tonight.

I think the standard mode groups should be fine and 55C sound like a good stepdown.

I plan on putting one in a skilhunt h03 headlight. Would it be possible to operate the indicator led inside the e-switch with this driver?

I did put a 21mm inside my Skilhunt H03
If the driver is configured to enable indicator LED it works adding a 4.7kOhms resistor to pin 7 like this

I can add that resistor already

If you want that I configure the driver add 1$ and instructions

[Tjhosan]

I will take one 30mm LDO 2s with Narsil then

No spring needed

[X31 (-X3-)]

I’d like one Narsil 20mm with short spring (okay for e-switch, right ? )
I plan to put it in my fried HC30, maybe with a triple 219C.

Your right, looks like I’ll need 21mm boards. The second driver is for an older skilhunt H02, looks like 21mm board also.

So I’ll take two 21mm boards and yes, please configure one of them with the resistor and instructions.

Are you using the default mode groups in you headlight? If you have any changes in the mode groups that work better for headlight usage please let me know.

Thank you very much.

[Lexel]

I did modify the modegroups a bit so they fit better to the 7135*5+1 I did put in my skilhunt H03

For a fully equipped 7135*7+1 the standard mode groups will be OK
You can look in the Narsil code and tell me changes if you want

As the light has a DTP star you could also get a higher temperature value when the stepdown kicks in, as it dont get too warm holding in your hands

[MrJohnny]

Hi Lexel I did requested for 1x 17mm bistro with long spring but i don’t see my name in the list.

[Lexel]

Narsil Triple v1.4 got released some bugs are fixed and temperature management got updated

Google Drive: Sign-in

@Tom E

Ok, v1.4 of the triple is up now. Find the files in my google drive share: drive.google - NarsilTriple v1.4 (link is external)

Let me know if you find it all ok. Can’t recall how familiar you are with it, but a notes.txt was updated. Turns out the “bug” wasn’t really so bad in NarsilTriple, but I did update how temp regulation works now - I think it’s better, dropping amps in lower increments, longer delay between drop adjustments.

The V1.3 manual still applies, accept for section describing temperature regulation - I’ll have to update that part.

Also removed the project folder under NarsilTriple (was a NarsilTriple folder under NarsilTriple), now the project is in the same parent folder as the solution file.

I will trust your judgment since your familiar with the host and driver. Please change the stepdown temp to what you feel is best. If you can make improvements on the mode groups I’ll trust your judgment on that as well. Otherwise we can keep them stock. Thanks

I’m a noob with drivers, but I would like to get one driver for my Convoy L6:

30mm, 2S, LDO, Narsil, short spring.

I plan to add a clear side switch with an led to indicate when the rear switch is on.

I would also like the option to have it turn on in turbo with the rear switch.

Are both of those easily done with the normal Narsil or does it require special work?

Thanks

[Tjhosan]

Please add the indicator led option on my driver aswell

[tekwyzrd]

Interested in an attiny 85 narsil in the size closest to fitting a courui d01.

The turbo on rear switch is just a few lines different code.
for the illumination of the sideswitch when rear switch is on I can add a 4.7kOhms resistor to the driver
Just keep in mind that a the driver supports as well a indicator LED you could add a green as power LED and a red indicator LED to the sideswitch
the indicator LED can be wired on Pin 7 with an additional resistor
I can add for both LEDs a resistor to the driver for 1$

Which size has the driver and how much space is in the lights body so parts dont collide with it

It is possible just to piggiback a small driver on the original board

there is a 38.5mm TA driver design that could fit

What about a 30mm size like these in a 1S with Narsil?

30mm Single-Sided FET + 7135 Driver PCB - V1.13 - MTN-30DDm

Could that it be used in utorch ut2?

Made one , 30mm LDO is the right driver .

Ok, great thanks.

Have you measured the result and of course, was it worth it?

Of course , now it’s an awesome light . First , it’s running Narsil and second , it’s making 292kcd with a dedomed xp-g2 .

@KawiBoy1428

@giorgoskok

You don’t need LDO for 1S…… 2-3-4S e-switch of course Zener for mechanical button switch.

Made the driver with LDO for low parasitic drain

More than 2S will burn the 7135 to hell

Yes on this FET-7135 driver, but I don’t run 7135’s only Straight up FET’s 2-4S no worries! Never used a LDO for a 1S 3v either and the Zener in 1S screws with the UI. But thanks!

Yes, please add both resistors. That will help me out.

Will I need to change the firmware code myself? I’ve never done this.

I assume that once the new line of code is added, the rear switch turning on will made the light come on in turbo, then I can press the side switch to turn it off to standby. Then it will function like narsil normally does, ramping up and down and turning off back to standby. Power LED stays lit.

Turning off/on the rear switch resets everything and makes turbo activate again.

Is this correct?
