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

I did some changes for 2S Narsil lights

the shut down voltage should be highter if the cells are not perfectly matched
not going below 3V per cell here

in a 1S light lower is no problem, but 2S needs some buffer

all SIR800 FETs are used now

:+1:

Great news! Thanks!

Pleasant surprise but if given the choice I’d rather you had kept it and had a :beer: as thanks for the time and work on these drivers. That said, I respect the decision and would do the same in a similar situation. You have my respect and appreciation and I look forward to the possibility of future offerings.

good news Kaidomain delivered 10 short and 10 long 6mm diameter springs today

here a pic, why 15mm Bistro OTSM is a bad idea as the driver has no C2, R1 and R2 pad
R1 and R2 are soldered together with the red wire in the middle and soldered under the Attiny25V to pin4 of the MCU
C2 sits on the indicator LED resistor with cut trace on one end
solder bridge from diode to C2
looks a bit messy as I had also to change C1 from 10 to 1uF

and my 38.5mm Cuoroi LDO piggyback 2S/3P
driver needs to be cleaned from solder paste and flux residue which got there getting it on the LDO legs and C2 soldered

today springs came from Kaidomain, so I soldered them for the people who dont think they can do it, it adds 2.5$ shipping costs and 0.5$ for soldering
on the 17mm driver with long springs its a tight fit

One thing discovered with Bistro OTSM 2S

2S LDO setup does not support LVP as it uses the internal voltage reference compared to MCU voltage
problem is the LDO gives the MCO constant 5V

Have you tried out the lvp on the LDO Narsil M yet? I hope it’s working well.

Btw, on my order I just want the long spring loose. I can solder it on.

so did the Bistro drivers I assembled so far
and the Narsil v1.4

I had 2 drivers where in 2S operation one AMC7135 had this parasitic drain issue when the driver is in sleep mode
they are oficially not build for 8.4V

still waiting on boards from Oshpark that I have ordered later as more were requested than originaly planned

I printed the shiping addresses with information which drivers and export declaration
then used residue tape to fix the drivers where they belong
also wrote on the tape the drivers specs

just amazing that big order from Kawiboy

cant compile NarsilM there are bugs in the firmware Tom E needs to check

If it’s giving you trouble, then you can revert my order back to the original v1.2 with lvp. I’m fine with that.

very bad news I got here a lot faulty Atmel Attin85s

all on the last reflowed boards can be flashed only once,
after correcting temperature offset I want to flash em again,
but they all get me an error

I even took a brand new one out of the cut tape and flashed em, same problem
this affects one 22mm, 3 46mm and all the chips I have in the cut tape

Are you sure it’s the chips that are bad? Maybe there’s a problem occurring in the first flashing process that makes the chip not able to be re-flashed?

I did flash the other chips of that cut tape with identical settings with Narsil v1.4
I tested 3 chips of the new ones with the same error

I even did flash one of the ones I flashed before with temperature setting and it worked without any problem

I ordered 10 Attiny85 chips from another source here in Germany

NarsilM is also now ready to be flashed so I can do 6 30mm boards as well

so a lot orders are shipped
the first 2 or 3 ones were done shipping today, but then the rest will picked up Tuesday,
because the driver came who picks up the stuff from that post office came when I did the first envelops and filled out stuff for the othen ones

tracking numbers can be seen here

date of today 03. June 2017
and your RR tracking number
the tracking most likely will start when they get picked up Tuesday


Thanks, Lexel! This is the second positive event today. The fwd clicky switch was finally delivered and now I see the drivers shipped… excellent!

Ok, sorry to be a bother. I haven’t followed every post here. I was trying to figure out if it’s possible I could get a driver for the Courui D01. I looked at the OP, but I’m not sure I’m understanding all the options and how they add up together. I guess it would be the 38.5mm driver, so that costs a bit extra for being a larger size. I want NarsilM if you’ve got it worked out, or whatever is the latest working version. I will do temp calibration myself. I want the standard amount of 7135’s on board. And it will be used with the normal 1S3P set-up of the Courui, with a ~3V LED, so I don’t need LDO and the LVP should be set for 1S operation with the standard values. I also don’t need a spring provided because I have springs of my own.

So, first, can I order one, or is it too late? Secondly, if it’s okay to order, what is the total price with shipping to the US? I tried to calculate it myself, but I’m not sure if I got it right. Please check and let me know.

  1. NarsilM with LVP calibration …… $15.00
  2. Extra cost for 38.5mm board …… $2.85
  3. Envelope Shipping Worldwide …. $2.00
  4. Add for tracking and insurance … $3.00

Total would be $22.85 - is that correct?

Oh, just looked again at post #2 and it appears that three 38.5mm drivers have already been ordered. I don’t need 3x of those myself. If any more get made, I’d like to get one.

yeah for this batch all 38.5mm boards are sold

vinte77 got his order reduced to one Narsil

so one Bistro HD OTSM is availiable again

Hi,

my drivers came in today. Looks very good.

Can someone tell me where to connect the eSwitch on the 17mm Driver?

Regards

Kenjii

the pads on 17mm size are marked OTC
