RGB LED Ring V2 — sequels don’t have to be bad @ My 2µF.

This is the successor to my old (and lame) RGB LED Ring project.

Version ’2.0 alpha’ – an intermediate step to true enlightenment – uses one LED driver IC and 3 P-channel MOSFETs cycling through the primary colors. This requires special attention in the code to attempt color balancing (forced dot correction at all times).

As of ’2.0 beta’ (likely to become the final version) it comes with 3 dedicated constant current LED driver chips (MBI5168), which completely avoids multiplexing the LEDs and boosts brightness again. Color balancing is done entirely in hardware using 3 potentiometers. The hardware differences should be taken care of in the core part of the demo code, ‘User-land’ code is mostly the same.

Lovely!

  1. Thanks for featuring my little project.

    If anybody wants a go, I have a couple of circuit boards left over. They’re small and cheap. If you need all parts, that can be arranged too 😉
