LEDs

  • LED strips
    • 60 LEDs / meter
    • 30x30 LEDs / panel
    • 15 meter / panel
  • ICs
    • WS2811 or similar once...
    • LED-Pixel
    • WS2812 or WS2812b (full color LED + WS2811 IC)

controller

power supply

  • 1.8 to 2.0 amps for 1 meter LED strips full white

software

first try

first experiments are done with simple light library to control LED strips by Raspberry Pi and build a demo mobile app to detect sound meter and blinken the LEDs by sound.

light library

first experimental library to control LED strips with WS2801 ICs by PWM.

  • 15m of WS2812b LED strips with 60 LEDs / m
  • 2 fadecandy boards (synced by software)
  • everything mount on one 50x50 cm aluminium plate
  • on front one 50x50 cm plexiglas plate to diffuse the light
  • 1 300 Watt (5V 60A) power supply (needed for full bright = 218 Watt)
