MNL: Networked LED Lighting

MNL is a multi-node high-power RGB lighting system. It consists of a controller (PC or embedded system) and multiple light nodes networked with RS485. The first prototype nodes are up and running, and we will be developing the second revision of prototypes in the coming months. Read on past the break for more information.

tinyRGB – an i2c LED driver


tinyRGB is a minimalist blinkM-compatible high-current i2c RGB LED controller consisting of only 10 basic components. The board is small and inexpensive, can be fabricated for as little as $1/board, and can easily be assembled by hand with a total component cost of around $3.

The OSRAM SLG2016 and AVR

I happened to scavenge a couple of SLG2016′s from some old workstation debug displays. After finally locating a datasheet, I realized that they used the standard ASCII charset, so they are extremely easy to drive. Note: The SLG2016 differs from the SLR2016, SLO2016, and SLY2016 only by LED color.

Arduino Leonardo - Interrupts

Arduino Leonardo – Interrupts

As of Arduino 1.0, interrupts are not supported on the Arduino Leonardo. I’m working on a project using the atmega32u4
