first 6 Oshpark boards and 200 AMCs arrived yesterday
today a big part of Oshpark boards arrived
just amazing how tiny a 17mm driver looks compard to 46mm
BUT
3 of the 22mm LDO bards came without contact ring on the MCU side
and 3 46mm SRK without the contact ring on the retaining ring side,
just removing the paint with a knife or chemical will work
I will contact Oshpark to get replacements for them,
but it should not be a big deal to use em, only if you got no problem with it
or you got to wait another 3 weeks
I’m a bit lost with HD OTSM, I haven’t spotted its existence until now.
Reading / skimming quickly through its topic I guess that’s what I want, but is there a summary of hardware differences somewhere?
Question for all (not just Lexel). I have ordered a 46mm for a Q8. I requested the temp sensor set to 60°C. I see on the spread sheet the other 46mm orders have selected 70°C. Am I being too conservative (setting too low)? What would you use for a Q8?
Forgive me my noobish question, but what output does this driver give? Is it able to light up an XHP 70 in an 18650 form? If so, i am interested
It’s a FET driver, so whatever the batteries can give.
In my L6 with Liitokalas it pulls 12 amps. If I put some good unprotected 18650 cells in my same light I doubt it would deliver the same amps just because the voltage will sag more under load. I’d guess 10 to 11 amps maybe.
Is that what you were asking?

Exactly Jason!
So basically, if i use 2S you can light up emitters up to 8,4V and lots of current up to a level where the cells or other parts limit the output?

Yeah, pretty much.

So I made some minor changes to the Bistro OTC board using a high quality 0805 capacitor with low temperature shift and only 5% tolerance this should get better than the standard X7R 0603 one when the light gets hot
also on ordering the parts I looked around and checked if there is a better 47uF tantal capacitor and I found that Flintrock pretty much choose the most expensive on market, getting another brand with identical specifications drop the price by 1$
as I got also over 10 of those capacitors price dropped also
the question is if I can use this new capacitor and save almost 1.5$ to the first Bistro OTSM material calculation, getting you a partial refund on the paypal transaction?
OK, I educated myself on Bistro-HD OTSM. Definitely looks like the thing, but I need a clarification. The firmware’s thread mentions that it needs ATtiny85 revision C. It reports that all trial to find it failed. Did you manage to find it?

Bistro HD OTSM runs on Attiny 25V
extra parts price for HD OTSM dropped to 1.5$ as I did change the capacitor brand with same specifications and are above 10 parts Digikey lower prices as well
0.92$ vs original calculation of 2.23$ for the capacitor
Lexel, on the 30mm boards what diameter would they be without the excess material on the edge?
Is the center part basically the same as the 22mm?

the center part is almost identical to 22mm, some parts have a little more space between em like the bleeder
you can reduce it to about 24mm and still got some copper ring around

I think that’s the driver I want, but I changed my mind twice in a week and would rather have it settle in me

Batch is limited to 58 drivers by the SIR800 FET
2 Backup MCUs ordered in case one is faulty like last batch so probably 60 possible with IFR or LF PAK33 (15mm)
43 drivers are taken 2 pending feedback

I’d like 2*17mm. Max number of 7135. It can go without firmware, I want flash my own Bistro-based image anyway.
I will flash it for testing the driver anyway, of course you can send me your custom hex file
Standard TA Bistro or HD OTSM?
OTSM has more expensive parts but no more issues with hot light and OTC timing getting almost unusable
springs?

I’m a bit lost with HD OTSM, I haven’t spotted its existence until now.
Reading / skimming quickly through its topic I guess that’s what I want, but is there a summary of hardware differences somewhere?
I’ll take 1 short spring.
Hi there,
Id like to get in on the fun. Intersted in a narsil driver for Convoy L6
My line on the spread sheet looks good.
Question for all (not just Lexel). I have ordered a 46mm for a Q8. I requested the temp sensor set to 60°C. I see on the spread sheet the other 46mm orders have selected 70°C. Am I being too conservative (setting too low)? What would you use for a Q8?
Lithium Ion Battery Safety
You will have to choose between having low voltage protection and no temperature stepdown (narsil v1.2) or
temperature stepdown, but no LVP (narsil v1.4).
I went with LVP and let my hand control the temperature.
