D.I.Y. Illuminated tailcap

Test it! Perceived brightness vs power draw at different input voltages

Oh I plan to, just like to know I have all the parts I would need ahead of time. I royally hate having to wait for parts in order to finish a project.

Then just get several values to start with.

Yeah, I am going to order some of each color.

No big deal, was just curious on peoples opinions for color and experience with LED models.

Every time this thread gets some attention, I start thinking about something I’d like to change. This time it’s to incorporate the header pins I got to use with the TripleStack.

So here is what I dub Rev5.3, Top and Bottom. The two boards are aligned so you can use header pins to connect them through the vias.

Top has Six LEDs, two channels, and two resistors for balancing colors. It also has a jumper pads to merge the two channels to bypass the resistors.

Bottom should be very familiar: two pots and the mini slide-switch to jump between them.


That feeling when you buy something and the very next day new updated version is released:

Lol sorry. If you actually ordered yesterday you can cancel as long as they haven’t been sent to fab yet.

There weren’t really any features added other than the pins anyways, so I wouldn’t feel too bad

They were assigned to panel in about 20 minutes from my payment and sent to fab. in less than a hour.
No speed limits for OSH park :smiley:

What switch can i use best for the 20mm rev4 ? I want to use them in a solarforce l2p tail, it has big square switch original.

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!

Ok I think I’m done with the OP for now. I tried to organize and simplify……. I think it ended up longer than before. :person_facepalming:

Oh well, at least there shouldn’t be any more dead product links.

Yes, it is much better laid out now and much more understandable. Good job!

The op looks great!

Did I read somewhere that there is a translucent boot for the s2+ metal switch boot?

There were some made, but they aren’t for sale that I know of. I had some I could send people, but I haven’t seen them since we moved.

Alternatively you can use the finger cut from a clear latex glove. It works pretty well.

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.

Wouldn’t be too hard. When I was editing the OP I noticed a few holes in sizes. Give me a couple days.

Thanks in Advance!

Will the following be enough:

Any suggestions for more pcbs (any kind)?

Any other PCBs? Hmm do you want to build drivers? There are a million of them to choose from.
