Talking about tiny amber smd leds, has anyone found a version yet that is a phosfor-converted amber? (so more efficient than direct amber leds) I have several PC-amber leds in powerled version but have not seen them in tiny format.
Good question. If not though, I should have Anduril working on the ROT66 soon, and it can run aux LEDs in four different modes if compiled with that option.
I think there’s a good chance of Anduril or something Anduril-like on a Fireflies light, since they’re looking for something like NarsilM but simpler.
I’ve got it running on a ROT66, as of about an hour ago, but I’m not done calibrating things yet. Gotta get the ramp shape fixed and the voltage calibrated, etc.
However, with a 3-channel driver and a switch LED, Anduril compiles just a few bytes too big to fit when I have all the options enabled. So for now I turned off the option for a blinking switch LED. It’s a little awkward anyway, with the arrangement of two always-on LEDs and two which can turn off.
Long-term though, I hope I can reduce the base code size a little bit so it’ll fit.
Okay, I just wanted to make sure you didn’t add a special circuit to the D4S driver or something. I don’t follow that thread so I’m not sure. (It’s growing too fast)
I got ya. The D4S does not have switch lights so you ran it’s aux board to the “switch light” output. Then, the fact it’s 2 channel (instead of 3 channel on the ROT66) means you have one leftover pin free.
As I do not have a ROT66 myself I can only post that I have first Aux board in my GEN3 tail setup finished and limited supply of LEDs and PCBs to make more as it was just first prototype of theese board design
basically the same as usual each LED has its own balance resistor so any combinations are possible
here just 2 rings in same color (ice blue and pink) that are dimable indipendantly with two trimmers,
the central 4 LEDs show low battery warning, the threshold voltage can be set as you wish with a resistor value swap
red for low battery has also its own brightness adjust trimmer, also any other color combination possible if you dont want red for low battery indication
right next to it my new D4S board also in Generation 3 here no circular pattern the trimmers are making a cross around the 4 LEDs
LVP shuts down all LEDs at the 2. threshold level, tested down to 3V, below that the LDO falls out of regulation and it stayes off until battery gets high enough above the hysteresis
Fireflies should have its own first prototypes tested right now but will very likely only bring only a blue and red for low battery variant with next batch
Fireflies is a new company but with some (they mentioned to me) experienced guys who worked for other flashlight companies before (they will not:say which). Before releasing their first flashlight they contacted several people on BLF for advice (they asked me about leds), which is a clever move, but they also have a good nose themselves for what are wanted features and are especially keen on high CRI. That is about what I know. Their first runs of their first flashlight, ROT66, show some teething problems but is seems sofar that they are very willing to solve that for the customers.
Finally got my Nichia version from the group buy.
First I thought they forgot the switch but then I noticed it was only the underdesigned lanyard mount :person_facepalming: .
But there was something black visible on the center LED, after removing the bezel it turned out as a solder clump. Removed it and light is ok now. Glad I checked before running the LED on full for a while which might have have burned the LEDs dome.
End control could be better though.
Bezel was very tight btw. and made a terrible squeaking noise when turning. I added some grease to the threads since I have to open the bezel again in future for a planned mod.
Did a rough lumen measurement with my Nicha version and got about 4800 to 5000 lumens at start, checked my last unmodified Q8 against and they showed almost the same values (within one or two percent), both with 30Q. Very nice tint, Q8 is green in direct comparison. But it gets hot very fast - much, much faster than the Q8. Temperature sensor doesn’t seem to be adjusted yet, after a couple of seconds the light is too hot to touch.
Anyway, I’m pretty impressed with this light!
