Okay, nice. The missing resistors are a feature, not a bug.
I don’t know if RMM re-compiled it to use pin 3 for the switch, but the original build used pin 2. It’s easy enough to test though; connect LEDs and power, and ground one pin or the other to see if it responds.
I find it very difficult to get a wire to stick to the tiny pads on pin 3, but the OTC pads are bigger and easier… and the OTC isn’t used by the D4 code so it doesn’t really need to be there. I’ve never tried having a capacitor on the switch pin, but RMM says it works fine.
With those changes the driver will, of course, not be usable for older firmwares which require an OTC or voltage divider. But it sounds like that will be okay.
OTC = offtime capacitor, used for measuring time while power is disconnected, on lights with a power switch instead of e-switch.
It’s required for bistro and blf-a6 and a few others, but has been far less common in newer firmwares because it uses up a pin and is prone to heat-related variation and is no longer required to detect short vs long button presses. (still required for short/med/long though, except in the case of bistro-HD, which requires very specific other hardware)
Also, totally unrelated… oops. I waited too long to order 30Q cells… again. I suppose I should still order without them though, unless they’re expected to come back in stock soon.
I solder the switch lead directly to the MCU pin, very rare for me to reflash an MCU after the light is built. I’ve seen times when it was pin 3, times when it was pin 2, so that get’s confusing to me but a pair of tweezers to “toggle” the switch off either 2 or 3 tells the story pretty quick. [4 is ground, easy to touch tweezers to 2 and 4 or 3 and 4 to act as the switch, just a touch of course, like clicking the e-switch… unless it’s a ramping firmware then hold for ramp]
I was browsing around the site last night and also noticed the SST-40 page. Look forward to seeing what bins/tints you can get your hands on. I really like the SST-40s I have from somewhere else.
Any chance of stocking the Luxeon V in the future? Maybe even get some DTP boards made for it? Djozz did a test on one using an XP board and the performance and tint look really good.
I’m finding the SST-40 to rock! Gained some 3,000 lumens putting 3 of em in my SupFire M6 over the XM-L2. Sweet, I can live with the color at this point, til they come out with better ones.
That’s 5,000+ lumens bumped to 8,866 lumens. The only thing I changed aside from emitters is that I re-flashed the MCU with TK’s ramping firmware.
30Q...in a week or so. Aspire? Who knows. I placed another order right after we received the last one weeks ago...they seem to take a while to ship. My guess is another week or so.
