Added info about the springs, to stay below 10mm envelope thickness is 2.2€ cheaper to ship, so they are not soldered to the boards

I will start ordering parts, ask for Narsil configuration and send payment instructions the next days

Quick question: I’m building out 2 jaxman E2L triple hosts (single 18650 cell, nichia 219c leds) with clickie switches. Is there any advantage to having the Bistro HD OTSM in my 17mm drivers?

OK, found the answer & yes, put me down for Bistro HD OTSM

3/26 Flintrock wrote: “OTSM. (I think TA named it that). I think it means off-time sleep mode or something like that. It’s the replacement for OTC in bistro HD. It means that the length of a medium click is as steady as the watchdog timer, which as far as I can tell is about 10% even when hot, which is much better than many caps. It’s also not sensitive to all the resistor tuning that the OTC is, so should eliminate those headaches.”

Yes, the OTSM is by far the better option. The old OTC is the largest complaint I have had with BLF drivers by far.

I highly recommend 2.8 or 3V LED cutoff voltage, down to 2.5V there is almost no capacity and the cell ages a lot more when discharged that low

I am sending out the PM requesting for final information which hard and firmware settings people want

on first PMs there was an error stating Narsil v1.4 has no LVP this is only for 2S configuration

Also Narsil with a tail switch there are different options how the light reacts when the driver gets powered up

Lights like the L6 with tailswitch can be set up to go in turbo when battery power is applied (called “tactical”), or 2 low blinks or nothing at all – Lexel

NarsilM has cut the option in advanced settings to memorize last level, making the settings UI easier

Topic is now change from interest list to making 3. batch

Excel sheet updated
check if the order is listed there correctly

PM are sent to all
requested for detailed information how you like the drivers configured and which shipping service to estimate final pricing

Payment can be done in € as well, with Paypal exchange the currency the fees they charge me are ridiculus high,
makes only sense if you have Euros or not USD as your currency

doing paypal transfers fill the right side out, so it calculates your local currency

Not bad, if you could get the PCB’s printed out as a panel then you could solder paste them all at once and save a ton of time!

I would need one of those sheets, but with the different sizes for TA drivers, also including the AMC7135 side, but I got no clue how to get those Oshpark files into one mask that contains all those sizes on one stencil plate

Then cut out the different sizes into round form to place em on top of the board

Don’t bother trying to get them all in one sheet, that would be WAY harder to deal with then just getting them individually. Just make sure to label them so that you know what is what. You can also reduce the edge clearance to the smallest they allow with this tiny drivers, there is no need for all that extra space.

They charge by the inch, so the total cost would be able the same buying them together or separately. unless you squeezed them together really close, which would make it very hard to handle later when you were actually using it.

on this one sheet you could place all sizes of driver stencils
the cost for one of those frames is always the same in those chineese shops, but I found only pretty expensive ones

Well, if you are ordering from some other stencil manufacture then yes, the pricing could be cheaper. From oshstencils though it would be able the same price due to how they charge by the inch and not by the sheet.

Do you have a 30mm available? You ordered 7 boards and have 7 orders, but it says you have 2 on order? I’m not sure I understand the chart.

I like my first one a lot. Is it possible for me to order a 30mm or is it too late? If too late, will there be a 4th batch?

I was hoping for a 30mm 2S LDO Narsil v1.2 with LVP, large spring, (tail switch – no output)

7 boards 30mm are requested so far
9 boards ordered from Oshpark, 6 last week, 3 yesterday as I got past 6 boards
So I got 2 boards that are left, like the 15,20,21mm that are left from last batch

From Oshpark you have to order 3,6,9 aso.
Thats Why I say big sizes makes no sense if I got only one requested and have to buy 3

Its no problem to make more drivers atm, if needed I will order more PCBs from Oshpark

But
when first Oshpark boards and the AMC7135 arrived here, then I am going to order parts from Digikey which get delivered within 2 working days UPS express

At this point the parts for a few more drivers are within that Digikey order for the case I screw up destroying a component building the ordered drivers.
Thats the phase, where I can add a few more orders and thats it for this batch.

Question regarding LVP in Narsil – can it be calibrated/set through the config settings or just in code before it’s flashed to the board?

My driver is going in a modded T01, so I’m trying to determine specs ahead of time unless it’s possible to do it in config.

Thanks!

EDIT: found the answer – it’s done in the firmware before flashing. I like the default lvp stepdown. Nicely done.

Yeah Tom E changed LVP to 2.8/3V for the Q 8 before it was 3.0/3.2V I can calibrate that to any level you want, 2S needs modified voltage divider And then change the setting before flashing to match 2S LVP

For medium single LED lights or big multi LED lights I recommend Over Temp Protection of 60-70dC

If your light has a tailswitch as well you can choose how the driver reacts to be powered on with a forward clicky tactical with turbo makes sense

more 30mm driver requests come in

I ordered today 6 more 30mm boards, but those drivers ordered lately will be ready a bit later as those boards will be produced almost 2 week later than the first

For Bistro OTSM 2S I got the information it may be running only with LDO properly, I asked flintrock if this is the case
