I started to experiment with the WS2812 LED, more specifically the WS2812B, which is a better revision in term of connections. These are the very famous individually addressable RGB LED, where tons of sources are available. Mainly due to their low cost, they are spread to the maker scene like a rhinovirus in a primary … Continue reading Experiments in implementing the WS2812B protocol in AVR MCUs without bit-banging

Tiny, robust, low cost, fail-safe LED driver: the Glighter-S project
It has been a while since the last LED related article. Was experimented the linear current source, its pros and cons and the field of application. Now arises the need of a small version, handling the same high power, things that are contrapposed in the linear regulator. I need something that I can bring with … Continue reading Tiny, robust, low cost, fail-safe LED driver: the Glighter-S project
Current sources for LEDs – Glighter: a multichannel LED Driver
A power constant current source, high speed, for power LEDs. Taken all the errors made previously, I tried a new linear based current source which should be kept "simple" and "fast".
