Nice, good work.
What driver we are you using?
I tried it on a stock 105c and whatever driver is in the Kronos X6…ATTiny25 FET maybe? Same results on both. The tailcap lights work, but they are just much dimmer.
I believe they will work on a lot of drivers, without a bleeder. However: They tend to influence mode changes, and mode timing, without one. Only you can confirm. I have one using a 105c, and it works fine. Others have had to add a bleeder for timing issues.
The resistors that measure voltage for low voltage protection bleed some current themselves. On drivers that do not use an Off-time capacitor to do mode changes (like the 105c), that might be enough to work without an extra bleeder.
The Kronos X6 drivers from BG come with a bleeder pre-installed since the groupbuy lights had basic illuminated tails from the factory.
Yes I can confirm it. With Astrolux S41S and LEDs on tailcap, you are not able to switch back the modes without bleeder resistor.
Thanks for the replies. Ok, so the modes work fine. I was able to lower the resistance on the blue channel and brighten them up. I think it’s just the purple leds that may not get any brighter. Going to switch those out with a different color.
My suspicion is that there is an effect from the led side too: you are more likely to get a messed-up UI when the new low-voltage leds (219BV1, 219C, XP-G3, 3rdgen.OslonSquare) are used, or triples/quads. A lighted tail in the combination: a lowvoltageledtriple/quad, is really hopeless, I have not managed to get that working in any mod.
I have used purple leds too (very appropriate: in a UV-light), and they are just very dim, not much you can do about it: 400nm is the very edge of the visible spectrum, the output is there but you will not see it, the same radiometric output in green would appear 100 times as bright.
Now I can’t stop doing this, and I’m gonna have to place another order to that Osh Kosh or whatever place.
Looks good Willy. :+1:
Hello everyone. I’ve just read this entire thread and signed up just so I could ask one question… Anyone have any spare parts they want to sell? I have 2 BLF A6’s and I’m interested in a couple clear tailcaps, 2 6 led boards (17mm dumb) and a few leds (red and blue) to populate them. I’m trying to avoid buying 5 tailcaps and hundreds of leds that I won’t need. I’m in the US and have PayPal if someone has spares they would like to part with.
Maybe someone could offer kits… :money_mouth_face:
TexasAce was selling completed boards. Not sure if he still has any or not. Its a bit more complicated than that though since many drivers need a minor modification too.
Honestly I’d recommend you just break down and buy the parts. 5 boards won’t last you long, cause you’ll be putting these in everything you can. And you can find multi-packs of 0805 LEDs pretty easily — 10 each of 8 different colors or something like that. Not a lot of waste and/or leftovers, really.
But if you really just want a few parts maybe someone can help.
I have all the parts except the PCB’s currently. Although I do have a fully assembled purple tailcap.
I should be getting some PCB’s in the next week or so and I should have an extra if you just want the parts but like was said the driver will need a bleeder installed to work properly.
Thanks Texas Ace. I understand the mods and tuning required I just don’t need 5 tailcaps and hundreds of leds. I changed the leds in the switches and dash of my pickup and still have a few dozen 3528 and 1206 leds left over with nothing to use them on. I will have to buy a resistor assortment to tune the lights. Maybe I should buy more lights… I could sell them at work.
the pot will take care of the adjustment, the only resistor you really need is the bleeder. I also like to install fixed bleeders on the tailcaps to limit max current to ~.5ma or so to reduce issues but it is not a must.
I put one of the rev5 ring boards in an Astrolux S41S. Nothing revolutionary here; I just wanted to share some photos:
There you go, just make more of them, flashlight addiction solves all of your problems!
I’ve ordered 6 sets of Pilotdog boards from Oshpark, 5 tailcaps from KD, 0805 resistors and leds assortment from BG, solder paste, and various other items. Now I need to order a few more lights and I’ll be all set. 
:+1:
Has anybody considered using a pot for the bleeder?
