The Luma Controller takes any audio input, calculates and analyzes a FFT of the spectrum, and sends commands out to a network of Luma nodes. This board duplicates the functionality of our music analysis software, but with greater flexibility and…

Next-Generation Luma Nodes – Build Timelapse
The next iteration of the Luma node has been fabricated and assembled! The new node incorporates 3 10W RGBW LEDs, controlled with constant-current buck drivers and an ATTINY2313 microcontroller. Like all Luma nodes, up to 32 nodes can be daisy-chaned…
Open Hardware USB to RS485 Adapter
While developing the Luma RS485-networked LED driver we discovered a need for a small and inexpensive USB to RS485 adapter. We designed an adapter with a FTDI basic UART chip (FT230XS) and an inexpensive TI differential receiver (SN75176). Our small…
Luma Node Development
Development has started on the next version of the Luma RS485 high-power RGB LED driver node. The new Luma node will include a constant-current buck LED driver, PCB-mount LED, temperature sensor, 16MHz crystal, and many other new hardware features–all in…
MNL Updates
Luma Node Revision 3 Luma high-power RGB controller boards just got back from the fab, and we’ve populated and tested the first of the boards. The new boards include a 3-pin fan connector (power, ground, and tach) as well as…
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…
