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?
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.
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?
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?
