making 3. Batch Texas Avenger "TA" / Bistro HD OTSM drivers fully tested running Bistro or Narsil, Clicky or E-switch, SIR800

As the deamnd for those driver is still there and my 2. batch is already sold out before I have shipped the first driver,
I am going to do another batch if enough BLF-lers are interested, you may spread the availibility of those drivers on other forums,
but I am not planning to go into mass production

Bistro-HD OTSM can be ordered in next batch, as it needs special parts and is hopefully bug free

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

This batch will be reflow soldered by hand, got enough expirience in 2. batch




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, 38.5mm and 46mm SRK are possible as well, but add costs depending on size

Information about this driver series 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
running Bistro
or Attiny 85
running Narsil Triple v1.4 latest version with fixed bugs
Narsil manual, a lot options to configure this one
http://www.metronixlaser.de/bilder/flashlight/Narsil_Triple_Manual_v1-3.pdf

NarsilM availiable for this batch
http://budgetlightforum.com/node/54635

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 60°C
standard time between steps will be 45s

temp calibration with heat gun

there are 3 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
NarsilM it is possible to choose between indicator pin and LVP the whole settings are reduced for an easier handling for the Q8

For 2S lights that use only a sideswitch or you dont lock out the light a LDO is needed,
the zener mod has a very high parasitic drain so this is only suitable for Bistro drivers

2S LDO is availiable for 17, 21, 22, 26, 30 and 46mm
2S Zener Mod is availiable on all sizes
Piggyback LDO on other sizes possible adds 1.5$

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 17mm Board will be phosphor bronze in 2 lenghs
for 15mm board the short spring fits or the long upside down
All drivers come without soldered springs, to stay below 10mm envelope thickness which is 2.2€ cheaper to ship

long spring

OR
short spring

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

you can choose soldering paste
recommendedn with lead
on request lead free 96.5 % tin, 3% silver, and 0.5% copper

Prices:

15-22mm
12.5$ TA Bistro / Bistro HD Attiny25
14$ Bistro HD OTSM changed capacitor brand and volume discount >10

14.5$ Narsil v1.4 Attiny85 with temperature calibration

NarsilM Attiny85
13$ flashed no settings,
14.5$ with temp calibration and max temperature preset,
15$ with calibrated 1S or 2S LVP / temp calibration and max temperature preset, this version has no indicator LED

per spring add 0.3$
soldered springs are possible, but it adds 2.5$ shippin costs
30mm add 1.5$
38.5mm add 2.85$ if 3 boards come together
46mm add 4.5$ if 3 boards come together
Zener mod add 0.7$
LDO 1.2$ 21mm and bigger only
LDO 17mm add 3$ more expensive parts

or you suply a hex add 0.5$

Bistro 2S Zener mods or Narsil v1.2 2S LVP needs to be adjusted with a customized voltage divider to the MCU add 1.5$

Bigger diameter than 30mm I will build only if multiples of 3 drivers are requested or the board price goes up to compensate the unused
38.5mm add 2.85$ if 3 get ordered, if only 2 add 4.3$
SRK size add 4.5$ if full 3 get ordered
SRK Size with more than 7 AMC7135 Bank add 1$ For 16 AMCs

I will buy two 17mm drivers w/Bistro Attiny25 & the longer spring. Right now I’m thinking the BLF A6 UI.. The full compliment of 7135s has no downside that I am aware so would go with that. I’m sure to be missing something.

The more complete this is the better as this is my first attempt at modding.

Will be running this is Jaxman E2l hosts with 219Bs & 219Cs in triples. Any suggestions appreciated.

Awesome! I’d love to be in for 3× 17mm and 1× 15mm bistro HD OTSM when the time comes. Smile

EDIT:

Long spring if they fit, please. Temp at 50C, and please use this hexfile:

https://1drv.ms/u/s!Ar2B1Lm23GEAgfADOdsuhjPw7cRGMg

and these fuses:

low: D2
high: DE
ext: FF

The customizations in that hexfile are moonlight defaulted to off, and the reverse groups have been modified to ultra low, then turbo/FET, then battcheck.

Thanks!

Basically I will ask people that had replied here as there is interest for at least 25 drivers, to give me a final number how many they take and send the payment instruction
When I have confirmation of people with the final number of drivers they take,
Then I will start ordering parts, and also as last time more for people who join in later

So if you tell me as early as possible a number you take for sure its better than a number higher than you take in the end

Interested in a 22mm ldo bistro or possibly bistro hd to replace the LD-29 in my Convoy L5. Single tube with 2× 26350 or double tube with 2× 26650 lii cells powering a xhp50.2 would probably be a good combination for this light. I like the light itself but the driver… not so much.

2S4P 18650 host to 4x xhp

for unfinished contest entry – can’t incorporate costs into budget…
another $80 on a light that lost…

Next entry: 4 lens zoomie…

next contest will be …

I’m thinking (2) 38.5mm drivers for a 2S3P Courui D01 – make it dual button – (E-switch/ tail cap) capable, Narsil.

(2) 22mm 2S Zener Mod Bistro.

(2) 22mm 2S E-Switch LDO Narsil.

Ok, no spring on the 22mm. I have some be-cu springs I can cut down and bend a bit to fit.

I got some Be-Cu springs as well, dont need to be cut and bend, they simply fit
but as you solder the positive wire to the top of the spring there is no need for low resistance spring, you can use thin steel springs
The Be-Cu springs are not nearly as flexible as steel springs, first time compressed they get shorter

Correct, the pass-through in the TA drivers means that spring resistance is a non-issue. All that matters is that the spring holds the battery in place and keeps it from hitting the 7135’s.

The potential problem is the length of the springs in the op. I’d have to measure but the original spring on the L5’s driver looks like 6 or 7 mm uncompressed.

We got interest on 30 drivers

a lot more information needed on Narsil version, Temperature and configuration as well if you want springs

When I am ready with it I will send out payment instructions and will order boards and parts

Manual for Narsil v1.4
http://www.metronixlaser.de/bilder/flashlight/Narsil_Triple_Manual_v1-3.pdf

NarsilM got released, it is a bit different with temp. calibration in User settings
The only improvement I see in LVP for 2S lights, but it lost some setings to get the UI Settings easier

Ok we met the minimum number of driver to start ordering parts and boards
I will order from digikey this time later when the first Oshpark boards arrive, so the number of drivers is not limited by an early order from digikey parts

Priced for Bistro HD OTSM and NarsilM updated

Option for customized modespacing/modegroups added or you give mne a customized HEX file

For the lights 60-70°C for single LED should be OK

for Triples in small hosts it should be less as the head can get hot fast while the LED driver is relatively cold

Lights like the L6 with tailswitch can be set up to go in turbo when battery power is applied, or 2 low blinks or nothing at all
It might be also possible over the advanced setting interface to get the light come up at last memorized level

No clue how fast it would reach that temp. Say 70.

Well startup should be memory or low.

For the temperature setting I would like 50 C on both of mine along with the standard mode spacing. I like starting on low

Thank you.

Thank you.

I am trying to figure out how to get the code working to start at low, when the light gets powered on with tailswitch
I hope those settings can be achieved
tailswitch PO: moon (M) low (L) Turbo (T) 2 blinks (2B) mode memory (MM) no output (NO)

On last batch when people did not specify a temperature for protection I set 60°C, not too aggresive but also a temperature where Triples on a Host like Eagle Eye X6 does not overheat
Its a protection if the light gets turned on unattended, lowering the output of the light, not a temperature control keeping the light on that temperatue

50°C is quite low for temperature protection, my nitecore P12 gets to 60°C and it is still comfortable to hold on the tube
Lights with DTP star have no problem to survive over 70°C head temperature,
there should be enough time that a good portion of that heat gets to the driver, of course the driver will always stay a big cooler than the head if its not potted to the shelf of the emitters
so the longer the light needs to heat up the more heat the driver will get as well, so the temperature can be set high

on Convoy S2+ Triles that draw like 12-14A the head gets very fast very hot, while the driver is still on a moderate temperature, there I would go for 50-55°C

Thank you for all that Lexel. Okay, I’ll go for standard 60 C for the temperature. I’m headed in the triple X6 direction. What you say makes sense to me. Thanks again!
