Umbrella

infos zum metalights projekt.

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

• 8 Mbit Storage (1 Mb)
