A quick look at a Convoy switch shows me definately polarity reversed
If you got only one sort of LEDs there is no need for a balancing resistor, but thinking of it some balance resistors would be useful to even out small differences of the LEDs like in the first batch of Q8s with uneven LEDs
I liked having a low and high “setting” I could easily toggle by flipping a switch. Being able to vary different colors with the pots sounds cool too. Feel free to continue development in my absence. I make no claims on the designs.
You would have to experiment with bleeder values and tail resistor values to find a set that works for the biscotti driver without messing with the UI timings too much. I have not tried that for biscotti, I just know that the BLF-A6 driver works with all kinds of values and that the BLF X5/X6 driver is very choosy.
When doing mine, I’ve always just added the bleeder. I’ve never even tried without. Figured it would just take less time to add it rather than to monkey around and try without.
I always just drop in a 680 - 750 ohm resistor and haven’t ever run into any issues. But I usually only use the nanjg105c, BLF A6, and Mtn Fet+1. Then again, I also use PD’s Rev5.3 boards - not those with the LEDs down by the switch’s PCB. Those configs use significantly different resistors on the tailcap boards.
Very nice find and a great price! I like that it also comes with an Omten switch. Too bad that it doesn’t have a double spring like the Astrolux switch, but doing a spring bypass isn’t too hard.
Cool find XXX-man.
Spring looks like its the same one used on the Convoy store 16mm Sw assemblies with Omten. Those springs are pretty stout for compression.
Anyone catch the LED color? I missed it if listed.
Washer is kinda different with the outer wall or recess. Great price for including washer and cap.
This is my first try at this Mod and need lil help, i have the Rev5.1 version with the leds soldered onto the board with the resistors and leads, from PD first post he has a bottom board ? can someone tell me what board i need and for the bleeder resistor where do u guys buy them in different mixtures
While they can be more convenient, you don’t need a special bottom board. Just solder the leads from your top board onto your switch PCB.
You’ll need to identify the polarity of your switch board. Put your DMM in continuity check mode and make sure the switch is in the “off” position (no continuity when touching each side of the switch). Now put one lead on the spring and see which leg of the switch it goes to - this is the negative leg of your switch. Solder the negative lead from your LED board to that leg of the switch, then hook up the positive lead.
As far as bleeder resistors, I just bought a just pack of SMD resistors (from ebay? banggood?). For most of my setups, a 680 or 750 ohm bleeder has worked out just fine. Regarding placement of the bleeder, just let us know what driver you’re using and we’ll take a stab at where to put it. It needs to go from positive to ground, but that varies from driver to driver.
