KOLOR - LED pixel strip controller for Eurorack

 These are some teaser videos of the new eurorack module "KOLOR" from Elkelektroik.

What is it?
Its a eurorack module that controls LED light strips, blocks, etc
With it you can syncronise LEDSs to add visuals to live modular performances

The module itself runs on standard euro +/- 12V.
The target LED strip however needs it's own power.
Its DC +5V or +12V depending on what voltage your strip requires.

It's compatible with multiple LED strips.

Control can be either manual (via the knobs) or CV patched into 6 jack inputs.

The controls are:
1. Red /hue
2. Green/saturation
3. Blue/value
4. width
5. pixel number
6. preset pattern











Ed will be releasing this on Kickstarter soon.

I'm changing some of the presets & altering the speed with a LFO

I'm using a Erica Synths Pico system III

the module uses a WS2812 LED strip.
This is a programmable LED strip where the control circuit & the RGB chip are combined into one package.
Each LED is addressable. You can daisy chain the LEDs and control them from a single module.

There are lots of different LED formats.
They can be square, rectangular, circular, strips etc.

...These modules are pixel controllable.
Ie, you can control right down to the pixel level.
A bit of random noise.

A bit about the power source for the LED strip.

Euro power is precious, and LED strips can suck up lots of power.
So to preserve the valuable juice for your other modules, Ed has added a second power input just for the LEDs




The very bottom on the left has the input for the power for the LED strip/circle etc.
This can be +5V DC or +12V DC (depending on your LED strip requirements).

The Green rectangular jack on the bottom right is where you connect the LED strip.
There is also a overload switch.


here is a closeup of the Power section for the LED strip.












You need to connect the 3 wires to the LEDs.

DIN = Data in
+5V & Gnd are self explanatory.









On the other side of this LED tile you will see the Dout , +5V and Gnd connections.

These allow you to chain tiles.
