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

If you want fully assembled and tested drivers reply here
Flashed and thermal calibrated MCUs are included.

This batch will be reflow soldered

Today 200 AMC7135 arrived and from last drivers I had 2 boards over
so i could fit the rest of parts to them, 21mm fully reflow soldered, 17mm resistors and Attiny25 hand soldered
need to use less paste especially on the FET, and add solder with iron to fets pad, as its not easy to push it down and hold still till the solder gets solid

you can choose soldering paste
recommended
with lead 62% tin, 36% lead, and 2% silver

*or *
lead free 96.5 % tin, 3% silver, and 0.5% copper

Oshpark has all boards from first order shipped, so it wont be long till first drivers go into production
Check the Excel screenshot if the information to your order is right, I keep it up to date dayly

Availiable options:

there are different sizes availiable 15, 17, 20, 21 and 22mm
those are cheap on the PCBs from Oshpark so I may end up with some unused boards
30mm and bigger are possible as well, but add costs depending on size

Information about this driver here
http://budgetlightforum.com/node/48447

There will be a very good SIR800 FET used
You can choose a custom number of 7135 less than the maximum

can be equipped with Attiny 25 or 85
running Bistro
or Narsil Triple v1.4 latest version with fixed bugs

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.

Drivers will be fully tested before shipped

Narsil v1.4 driver will be thermal calibrated as well
you can choose the temperature for stepdown,
the time for stepdowns depends on the lights size/heat, a Pocket rocket off a 14500 high drain will need a shorter time than a Convoy L6
standard will be 55°C
standard time between steps will be 45s

temp calibration with hairdryer

custom mode groups can be programmed for a small price depending how much to modify

ATM there are 2 main options for 2S Narsil for lights like Convoy L6
Narsil v1.2 utilising low voltage protection on pin7
Narsil v1.4 utilizing indicator LED on Pin 7, has some bugfixes and temperature protection
but Tom E is working on v1.5 where it is possible to choose between indicator pin and LVP

For 2S lights that use only a sideswitch or you dont lock out the light all the time a LDO is needed,
the zener mod has a very high parasitic drain

2S LDO is availiable for 17, 21, 22, 26, 30 and 46mm
2S Zener Mod is availiable on all sizes

efficiency advantage over Fet+7135*1

this is just an example, keep in mind that triple hotrods get more gain than a single emitter light

Springs for 15 and 17mm Board will be phosphor bronze
long

OR
short

http://www.kaidomain.com/p/S020404.Silver-Coated-Phosphor-Bronze-Spring-...

For larger boards I recommend those springs
http://www.kaidomain.com/p/S024318.DIY-Gold-Plated-Battery-Driver-Contac...

for 20mm and bigger a larger diameter spring can be used

Prices:

15-22mm
the Bistro Attiny25 12.5$
the Narsil Attiny85 14.5$
spring 0.3$
30mm add 1.5$
Zener mod add 0.7$
LDO 1.5$ 21mm and bigger only
LDO 17mm add 3$ more expensive part
Bigger diameter than 30mm I will build only if more than 3 drivers are requested
SRK size add 4.5$ if full 3 get ordered, if only 2 add 7.25$
SRK Size with more than 7 AMC7135 add 1$

2$ envelope shipping worldwide below 50g
tracking adds 3$
Insurance and tracking adds 6$
1€ Germany below 50g

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

the bigger ones can be used as 1S or with a LDO for more cells

of course other sizes like 26 or 30mm are possible like in TA thread
as you pay for board surface 3 30mm cost 7$, if I only build one I got 2 boards that want to be payed
for SRK each PCB costs 5.5$, so if I make only one 11$ of boards unused

its not the problem to make other sizes as they are done by hand,
just Oshpark send minimum of 3 PCBs, so its a cost factor if I only make one and pay for 3 boards

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

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

Ill ask Tom E,
but as its Narsil triple v1.3 likely fixed
a lot features like temperature stepdown added to the original Fet+1*7135
and those boards come with pad for a LDO

Tom E has fixed the LDO low voltage not yet in Narsil triple
in Narsil 2 channel its already implemented

Tom E wrote:

Hhhmmm. Fixed? Depends on the board/usage. I’m using a fully configured “Narsil” 2 channel version (not 3) with a properly configured LVP support for a 360K r1, 47K R2 for 2S, LDO of course, and it’s working great.
It’s in a v1.3 not yet posted though.

No, sorry, no R1/R2 support yet in the triple version.
Tom

I am sure it will be in triple soon
I will give this batch some time to get enough people in to get enough to get free shipping from Digikey

Ok, great thanks.

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

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

Awesome!! Thank you for doing this!

I would like:

3 × 17mm Bistro

1 × 30mm, 2S, Narsil (is this what I would use for a L6 mod?)

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

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.

Slowly sinking into the dark abyss of addiction...MUST buy lights !

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.

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

Narsil Triple v1.4 got released some bugs are fixed and temperature management got updated
https://drive.google.com/drive/folders/0B1IxYZuk4DjcUERkZGpmdnBsWFk?usp=...

Tom E wrote:
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
