Most of these are designed for the Omten 1288. Others may fit but you’ll just have to try it. The BIG SWITCH version might be best. It will be added to the OP soon.
I am currently editing the OP over the course of the day, so don’t be alarmed if parts are missing.
Jumpers on the top ring are a great addition. For single-color tailcaps I’ve been relying on the pot’s resistance and just jumping all of the resistor pads together with a piece of copper braid, but had to be careful with the placement so it still stacked flush. A thin solder connect over such a small jumper will be much thinner. Thanks!
Read thru the post carefully and have ordered some Rev4 & pyro1son 16mm boards. I have also ordered my LEDs, pots, resisters and translucent tail caps. I will need to hunt down or create a transparent/translucent washers. Just waiting on the slow boat at this point. I have constructed 18 Convoy C8s so far. 14 of them I gave away as gifts. The Convoy C8 hosts I used were the version 3s with the integrated aluminum shelf. The tail switch uses a Omten 1288 type switch. The switch board is 16mm x 1mm. The ring/washer is 18mm x 1.4mm. I will share my results when I have some. I would also like to appeal to pilotdog68 on the creation of a 18mm Rev 5.2.
I still have a hundred or so translucent silicon thingies for the S2+ which I can sent out for shipping costs. Even to the US it is just $1.70 from here (long live postnl!).
(that reminds me there was a request for them that I never sent, I’ll look that up :person_facepalming: )
Stretching out a board to a larger size is usually pretty easy. I’m doing that to Rev5.2, and we already have the BIG version of 5.1. Any other sizes I should do? Most of them are purposely a little small because I don’t like having to sand off the little nubs Oshpark leaves on stuff. I account for them adding some size so I can still just drop it in the light.
I just built a lighted tailcap in my S2+ with rev 5.1 board. I had a problem with channel 3. I want to put green leds on channel 1 and 2 and red on 3. 4,7K resistors worked fine for channel 1 and 2 but on channel 3 the red was very bright. I tried to raise the resistor to 47K but nothing changed and the current stayed the same. I started searching for shorts and found that the ring positive connection is shorted to channel 3’s trace on bottom side so the resistor is shorted.
Cutted the short with an X-acto knife and it was OK.
Then I found the result with two green and one red led not really nice, and changed to six green leds.
The final version is barely visible at daylight but in dark it’s good and not disturbing. Overall current is 1,06mA. I needed the low current cause I use it in the 18350 version S2+
