Our team (Pigmice 2733) is hoping to make ~35 feet shots using a JeVois for vision tracking, and to do so you need a pretty bright LED ring. We’ve been working on a ring similar to the superbrightleds.com and Andymark ones, but much brighter.
Our current design is 58mm OD, 42mm ID and uses 24x 3.2v @ 30mA LEDs. It draws about 2.81 W and produces approximately 160 lumens of luminous flux. By comparison, the 60mm green LED ring from superbrightleds.com daws 1.2 W and produces 69 lumens (with the same apex angle of 120deg).
It runs off 12v which means it’s trivial to use a Spike relay connected to the PDP to only turn on LED ring when we’re vision tracking (see R8 m.), and if it’s still too bright we can easily swap out the resistors.
You can find the KiCAD files, BOM, and Gerber files (under releases) here: https://github.com/Pigmice2733/led-ring (DISCLAIMER: we have yet to test this design. I’ll update the thread in ~5 days with whether it’s confirmed functional).
