Why

The metalab needs some new lights.

ART-net is the name of the game.


How

Raspberry Pi 3

Distro based on the QLC+ image (raspbian jessie)

Hostapd for Accesspoint mode

QLC+ X-server less build that renders directly in GL buffers for performance

H801 based clients (ESP8266)

Arduino based firmware that implements ART-net


Costs

One time costs:

  • 1 Switch 3,-
  • 30 meter cable
  • 1 Raspberry Pi 3
  • 1 SD card
  • 1 7" Touch screen
  • Acrylic case


Per umbrella device:

  • 1 umbrella 24,-
  • 1 H801 10,-
  • 1 Power supply 12V 18,-
  • RGB ledstripes 5-20,-
  • COLDWHITE ledstripes 5-20,-
  • WARMWHITE ledstripes 5-20,-
  • 3D-printed parts for mounting
  • Lasercut parts for mounting

TOTAL 70,- to 100,- / umbrella

We need at least 12 at most 20 pcs

The more umbrellas the less leds / umbrella are nedded

A similar setup from a professional light company would cost >10k so this is actually very cheap in comparsion to commercially available solutions.

Hardware

H801 Ledcontroller features:

  • 8 Mbit Storage (1 Mb)
  • 5 channels each 45 watt max (~ 3.5 Ampere @ 12 V / channel)
