Hmm. I just like the Short L2 But I don’t want to use 26350-s. How much is the too much current? I don’t really care about runtime. Just max throw in a compact form. Or the current will be too much for the driver? Or like the XP-G2 the forward voltage going too high? Sorry for lot question but Soon I will be ordering from you some boards or complete drivers. :money_mouth_face:
I think many of us are waiting on the boost drivers… Having said that, I think Lexel is having issues with the firmware (narsil or bistro) working properly with the new drivers and he’s reached out to the driver gurus but they seem to be busy/nonresponsive.
lexel, I finally got around to installing your GT driver in the XHP35 MT09R and WOW! It was only “decent” before but now serious. Stock led, smooth ramp 80% NarsilM v1.2. Got a little chirp on contact charge but good now. I took your suggestion and did not bypass the springs. Great driver! Keep up the super work!!
replacing the at 2S unreliable AMC7135s
DD + small FET and resistors instead
MT03/09R XHP70.2
support of permanent switch LED plus MCU indicator with resistors
30mm for Convoy L6/ Thorfire S70S
support of permanent switch LED plus MCU indicator with resistors
20-22mm with 2 FETs and also 6+1 AMC
here with 1S configuration with 6+1 AMC
I had to drill out one via on the spring side partially that secures the switch pad from lifting if soldered too hot
17mm 2S with 2 FETs
17mm LX v1.0 FET+5+1
more filtering caps for very high drain builds
Not sure where the best place to ask this is, so I’ll give it a try here. I had some boards made using: your ‘new’ 17mm TA layout. I built one in a 1s configuration with an ATTiny25v with no LDO, Zener or bleed resistor using recommended components and resistor values.
I flashed it with the bistro-TAv1-OTSM-HD-attiny25.hex file provided in the Bistro-HD v1.7.1 distribution.
It works great, except for one thing. The voltage readout is wrong. It usually reads out 4.2. I may have seen it go as low as 4.1.
My understanding is that the firmware I am using reads the voltage from Vcc. So I am really at a loss as to what could be wrong. My understanding is that 1.7.1 is pretty well tested for OSTM configs, but should I be using v1.4.1instead?
