Firstly, has anyone ordered LED’s from digikey? Any recommendations?
I am thinking I will grab these in a few colors to start out with, they have the highest MCD rating for the price/size so I figure they should net more light at low currents as well.
Next is color, I am thinking I would focus on green or blue/green combo as they should be the brightest for the least amount of power used since our eveys are more sensitive to those colors. Or is red just too good looking to pass up?
On the newer boards the power is so infinitesimal, just go with what color you want. Having said that, you could look at it from the angle that reds and oranges have a lower Vf, so they need less power to be as bright as the greens
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.
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.
