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)
  • shop

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.

t.b.d.

prototype panel with 15x15 LEDs

first test panel is ready and working great:

  • 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)
