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

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?

http://www.mtnelectronics.com/index.php?route=product/product&product_id...

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 .

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 Smile

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?

I will flash your driver set to highest mode instead the 2 low blinks on drivers when you are requesting it.
As well other temperature for stepdown is possible, default will be 55°C depending how the light is build the head gets hotter than this value.

So every time you turn on the light with rear switch you will get a lot of light, so you could morse your SOS on your own,
a short press and the main LED turns off the power LED still on,
long press to ramp down or enter mode selection

I thought about a short video to explain how to operate and enter config mode of Narsil

Basically you can configure Narsil as you wish, ramping or modes, Mode Memory, indicator LED, Monn mode ON/OFF, brightness of moon,
just look in the manual its well written, after done the setup one time you get it, its similar to Bistro but a little different
after configuring 3 drivers for me its quite intuitive UI in the setup mode

This sounds great. Let me know when your ready to order it. If you only have 1 or 2 of this driver instead of 3, I might order one more so your not left with too many unsold drivers. Maybe I will buy another L6 to put it in. Lol

O.P. got updated with some other options
for 20mm and bigger sizes its likely to choose a spring with bigger diameter, that has less height when compressed

The extra boards on the 30mm are pretty cheap, the most comes from parts costs
only on 46mm SRK sizes the PCB price gets close as the parts for it costs, so it makes no sense to sell only one of this size and have 2 boards for 11$ left

I am not planning to stock those drivers in different sizes, just produce what is requested here and order some more of the 17 and 30mm,
as I am sure there will be more requests for those sizes as I wait for the parts

I tested Narsil v1.4 today, seems to work fine

Had a short chat with Tom as there were no clear comments about the new startup configure lines
Seems LVP for 2S configuration will be implemented in Narsil triple,
as Narsil for the Q8 is similar to Triple v1.2 where the LVP for 2S works he can port the part with LVP and temp calibration to the triple easier

Tom E wrote:

Yea, I knew this was confusing… I should have fixed it up.

This is 2 blink on start:

#define STARTUP_LIGHT_OFF

#define STARTUP_2BLINKS

This is max on start:

//#define STARTUP_LIGHT_OFF

//#define STARTUP_2BLINKS

This is off, no blink on start:

#define STARTUP_LIGHT_OFF

//#define STARTUP_2BLINKS

Is this helpful? I’m pretty sure it’s correct.

Ohhh- btw, I’m working on porting temp regulation into 2 channel Narsil, so I’m figuring this stuff out, so adding 2S LVP to 3 channel NarsilTriple should be much easier.

Tom

I forgot to show my old used crappy test bench for drivers

here for temp calibration with hairdryer

Does Oshpark just make the empty circuit boards and you have to buy all the components and solder them on?

I have a couple questions regarding the narsil driver for skilhunt h02.
I want to have the least parasitic drain possible. Do I need LDO? Are there disadvantages to LDO?
Will the e-switch indicator led option increase the parasitic drain.
Since its a 1S light I’m assuming the driver will have low voltage protection. Will I loose LVP by having the indicator option?

Is narsil “fixed” for 2s now? like low voltage warning.

If yes i could be interested in a 30mm one with a LDO

Low voltage warning is quite obvious on a DD light, it will get very dim, like <0.5 Lumens on a XHP70 when the batteries get below 2.8V

LVP shuts down the light in any case, LVWarning just reminds you to switch batteries, both is running in Narsil v1.2 fine for 2S
In 2S configuration the MCU does not see the cells voltage from Vcc of the MCU as it is regulated with the LDO
In Narsil v1.2 the LVP is on Pin 7 with a seperate set of resistors, no problem to flash this, but you loose temperature stepdown and indicator LED

in v1.3 and 1.4 he added there a indicator LED, those also have temperature stepdown

he is working very much on Narsil for the Q8, and will look into getting the 2S LVP
if he releases v1.5 I bet there is an option in the code to switch between indicator LED and LVP on Pin 7

it comes down that the Attiny 85 has a limited amount of IO pins, if it had more he would not have to remove the LVP in v1.3

The first 10 driver I soldered with an iron, took me about 35-40 minutes for each driver

This batch i will order solder paste and reflow em
I hope to get below 20 minutes per driver to assemble the driver reflowing

Bistro:flashing and testing Bistro adds another 10 minutes,
but a faulty one eats easily half an hour or more if you have to unsolder the 7135 for example if one is faulty

Narsil: Configuring code for different setups, flashing, testing, add resistors for Diodes and temperature calibrate the Narsil takes about 20 minutes

In both cases its possible to modify mode groups in source code if requested
or configure the driver as you like
It will add a little fee as it takes time

I calculated the prices above with about 10$ per hour just the time to assemble and test,
the first ones will be slower but with that many drivers I can reduce the time

the raw material costs for a 21mm Narsil are about 8$

there is no more parasitic drain on the 1 cell driver than the original Skilhunt driver
The LDO is only for 6V LEDs like XHP50, XHP70, or MTG2, with it the parasitic drain is also really low

just the 6V driver with Zener mod draws a few mA when off
as there are such nice LDO boards i would not recommens anyone a 2S driver with zener diode
a few hundred uA can be used for lighted sideswitch adding the bleeder resistor mid air and solder the LED wire on it

the indicator LED can be configured in Narsil to act as locator beacon, only this will increase parasitic drain, but the 1S driver got in any case LVP ad shuts down when the voltage drops betwenn 2.8 and 3V

you can read the manual for narsil, to see what a rich set of functions it has
https://drive.google.com/drive/folders/0B1IxYZuk4DjcUERkZGpmdnBsWFk

the main settings are:
Setting # Function Clicks Defaults
1 Ramping Mode 1=disable, 2=enable; 2
2 Choose Mode Set 1-8 (1-7 is # of modes) – see Mode Sets; 4
3 Moon Mode 1=disable, 2=enable; 2
4 Mode ordering 1= sets low-hi, 2=sets hi-low; 1
5 Mode Memory 1=disable, 2=enable; 1
6 Turbo Timeout 1=disable, 2=30 secs, 3=60 secs, 4=90 secs,5=2 mins, 6=3 mins, 7=5 mins, 8=10 mins; 1
7 Blinky mode 1=disable, 2=one strobe, 3=all strobes/beacons; 3

the optional settings are:
1 Set Moonlight Level 1 – 7 (PWM value); 3
2 Active Temperature Regulation 1=disable, 2=enable; 2
3 Locator LED feature 1=disable, 2=enable; 2
4 Batt/Temp/Vers Ind. LED Only 1=disable, 2=enable; 2
5 Indicator LED Enable 1=disable, 2=enable; 2
6 Power switch modes w/mem 1=disable, 2=enable; 1

I also thought about UV hardened glue to fix the position of the SMD parts before reflowing

I have no expirience with it, I guess watch the reflow on my stove and carefully push misaligned parts with a toothpick should work as well

Anyone got expirience with reflowing boards with 0603 parts?
This should make it possible to both sides of the boards reflow in one run

ordered this stuff

It’s really nice to see the driver available from an EU source as Thumbs Up well

I would like :
Two 21mm 1s short spring, with Narsil (for two Skilhunt H02)

What version of Bistro is it ? TA’s version or TK’s version.

Skilhunt H02 needs the Narsil firmware as it is sideswitch only
current release is v1.4 for 1S lights
unless you want switch modes by unscrewing thailcap with Bistro

The Narsil driver will be equipped with an 4.7k resistor for the switch LED
the red wire goes to the LED of a resistor soldered to pin 7

this is my modded H03 with narsil 21mm
first try on reflow soldering with 0.3mm solder wire, definately need paste

Made 22mm (or 21mm) LDO driver with 0603 resistors. Nothing extremely difficult , you just need to be careful placing the 0603 parts because they are tiny .

It is TA bistro with Triple channel.
Mode groups and hidden modes are different from stock Bistro.

This has all the information and link to firmware

Ok skilhunt H02 has no indicator LED, but you could add one

Thanks, can you please put me down for a 20mm 1S Bistro as well,you don’t need to add the resistor to the two 21mm drivers putting a indicator LED in the switch is way beyond my skill set Smile

EDIT : 20mm 1S Bistro long spring

The Narsil driver will be equipped with an 4.7k resistor for the switch LED
the red wire goes to the LED of a resistor soldered to pin 7

It is TA bistro with Triple channel.
Mode groups and hidden modes are different from stock Bistro.

This has all the information and link to firmware

Ok skilhunt H02 has no indicator LED, but you could add one

Thanks, can you please put me down for a 20mm 1S Bistro as well,you don’t need to add the resistor to the two 21mm drivers putting a indicator LED in the switch is way beyond my skill set Smile

EDIT : 20mm 1S Bistro long spring

an easy way to place an indicator LED is drill 2 small holes through the switch PCB
use some epoxy to glue the wires in there so that the insulation is a tiny bit outside so there is no short
the glue helps to cover copper if there is some where you drilled the holes
then solder a SMD LED on the 2 wire ends

Good news for the 2S drivers

For Lexel or anyone interested, I’m figuring out the support for adding R1/R2 LVP (2S cells) to NarsilTriple, but it will mean losing the Indicator LED support, so must be a compile switch then.

I am going to order the parts and boards next Monday

OP updated prices for phodsphor bronze springs and increased costs on Digikey.de due to changed parts costs
