The second version was for [[OHM2013]]..

It is now located in the space as mood-light

The third version was for [[SHA2017]] but the second midi port (for the second mixer) failed and needs to be looked at for the next revision (H-2021)..

Description Andon light/signal tower
Picture
Andon in the space.jpg

synopsis

Andon live in the studio

An andon light is a color-coded visual display for process state control; in short: On-Air light

The first version is completed, and used in the Binary Voice studio at the CCC2011. The second version was for OHM2013.. The third version was for SHA2017 but the second midi port (for the second mixer) failed and needs to be looked at for the next revision (H-2021)..

implementation

I used a light tower/andon light which a good friend Spert modified to fit 6 leds in it.

prototype

Since the media plugin doesn't work, you have to open the file manually:

andon 1.0

The first version listens on a serial port and change the lights depending on the data it receives. On the PC, an application listens to the midi signals and above certain channel thresholds, it will send out the correct signal data over the serial port.

andon 2.0

Currently being worked on..

It does:

  • do on-board MIDI
  • work stand-alone
  • switch a 220V 2A relay output as well

todo

  • publish both PC c++ midi-to-serial-instructions code as well as the arduino source
  • read values from EEPROM
  • store values to EEPROM
  • add relay that can switch outlet power
