Greeeg over at the 430h forum has been working on a RGB LED ring clock:
The clock is comprised of 2 rings of 60 LEDs each. the LEDs are WS2812 parts, which include a built-in driver.
The PCB is one of the interesting parts of this clock. I designed the board in altium as a single 6 LED segment. and then left pads at each end to allow them to be soldered onto another segment.
Currently I am using a MSP-EXP430FR5739 board to drive it, using some very in-efficient assembly code that requires a 20MHz clock.
Via 43oh.
Might be off topic, but has anyone seen similar integrated RGB Diodes + Driver ICs in other packages? I’m particularly interested in the standard 5mm style.
8mm through hole WS2812s are on the horizon, apparently.
Those would be convenient. I found these on Alibaba that should meet my needs. Its a bonus that they’re the OEM, and can hopefully provide me some with custom length wiring.
Double ring LED clock is looking nice and innovative. Good thing in this clock is that there are built in drivers include with the device so you need not to install.
