He answered but as I mentioned before it’s better to discuss some questions directly because the key point is always lie in details. I just dont know it all. Fonarevka is opened for everyone
“The most suitable driver for such purpose based on STM32F050 or something else. It has usb loader, can be coded on C. ADC and PWM works faster and that must be enought for such purposes (there’s no hardware division, C in a few times slower than assembler but microcontroller has advantage on 48Mhz and 32bit). 3V LDO is needed (ACS711 for example), also a normal thermal sensor that does’t requere callibration. The rest scheme part is the same. Thus people could easily develop, flash and configure driver through the usb. The existed scheme is based on AVR, code is unclear and sensitive to edits. Here it is in open access, if someone need it they’re using it as is…” http://forum.fonarevka.ru/showthread.php?p=1035146#post1035146
Personal contact is important. It’s not even necessary to get a licence in some cases. For example, I got a permission to use a non commercial driver firmware in my project that I want to finish this year. So it’s all up to you, hope I’ve assisted a little bit.
I’ve considered using STM32 controllers, but for now even a tiny85 feels huge. Normally I have been using only tiny13 and tiny25, which work pretty well with C. Tiny841 also looks nice, with extra pins and some newer hardware. But if that becomes too small, STM32 is the next step up.
I don’t think that “50% battery” is a valid comparison. If you arrived at 50%, you used it for X minutes. Weaker flashlight after the same runtime will have more energy left and after long enough X it will surely outshine a DD light.
Yes I do and should weight the same as all of them, very little weight difference in the weight of emitters and frankly IMO it’s a bit much for this light, cold to blazing hot in 30 seconds or less so if your just wanting to shock and awe someone well that will do it, but if looking for working light at higher levels this might not be it, sort of depends and I don’t have a box yet to do any OTF testing, I think TK might have specs for that, or soon anyhow as she’s in the groove for furthering development now. Sorry I couldn’t be of more help, just a mention, I also have the Nichia and S4 2B which are cheaper than XP-L HI 3A and more usable so not sure really if I would spend the extra $$$$ again, working on toning it down some, different emitters.
Edit: May have misunderstood your weight/heavy question, ha ha, duh…
D1, will be coming first which is going to be available in 18650 18500 and 18350
Very small size, throws around 40Kcd.
Probably in the middle of the month towards the end of the month, D1S will follow soon.
Hank, have you thought about selling Emisar hosts? There was some discussion about people disappointed with the driver. Now I got in a position where I’d like some D1 with XHP 50.2 which I guess will not be available….
Hank, big fan of your lights here man! Could you possibly lay out what emitters options will be in the D1, D1S, and D7? For the record I own one of your earlier C8s and I own 3 D4s, and have another one on order from Richard. My brother owns a CW version of the M-34. Each flashlight that I own that you produced has had no problems I have encountered. That is an excellent track record indeed.
