Supfire S1 small 16340 tube light, fixed BLF-A6 driver with 460 Ohm bleeder, 219C R9050 SM353, switchboard with 50K pot under the spring, lighted ring with 3x 3.3 kOhm and 6x slow colour change 0805 rgb leds from ebay.
Fun is that the leds are not completely autonomous, they slightly influence each other’s timing and actions so that the cyclus becomes partly chaotic.
Hey all, hoping to get some advice. I ordered some of the LEDs djozz linked above and a built a 19mm rev5.1 board with them, but it doesn’t work nearly as well as his does in the video. I first built it using a single 22kohm resistor and it was basically a red flashing board, with the colored emitters just dark the rest of the sequence. So I figured maybe it was a power/voltage issue not allowing certain colors to illuminate, so I lowered my resistor to the same 3.3kohm value djozz said he used above, with the biggest difference being that my board only uses 1 for all 6 emitters; its not the 3-channel board. Now my tail has roughly 3 colors, red > green > blue, with some flashing and pulsing in between (maybe there’s supposed to be other colors in there? it almost looks yellowish sometimes.), but after a cycle or two, just a couple of minutes, the blue and green stop working too and I’m back to a board that pretty much just pulses red. Its really not a bad look, the slowly pulsing, undulating red, but its not what I was expecting. If I use turn on the light, cutting power to the tail, it starts over again with multiple colors, but every time, after just a few minutes of working, its down to just red.
Any thoughts? Should I try even less resistance since all 6 are pulling through the 1 resistor? I don’t really want it brighter, but I may have to. Are these just not as good as his original emitters?
As menrioned in my post above I noticed the influence that leds have on each other too, blue is getting scarce if you let it run for a while. My circuit at least has the 3.3kOhm before 2 of the leds parallel, and that 3 times. My interpretation is that the leds have the most influence on the other led directly parallel and less on the other 4 leds. You can also try a separate resistor before each individual led, that may cause the least influence, or one resistor before all 6leds parallel, in which case they all feel each other. Is that last the case in your build?
Yes right now its just got 1 3.3K resistor with all 6 LEDs in parallel afterwards. But the board does have pads for individual resistors. I’ll try rewiring it with separate resistors to see what effect it has.
My tailcap reads 0.64mA at first “connection”, but it fluctuates between 0.4-0.8 as it runs through its cycles.
