FT LED Matrices At Noisebridge
[edit | edit source]
- Flaschen_Taschen - Runs fully featured ft-server built out of beer bottles and WS2811 pixels.
- Small LED Square - 64x64. Made from salvaged 64x32 P4 RGB LED modules. Downstairs near the front door, on the wall. Runs fully featured ft-server and rickrolls you! Send packets to led-square.noise.
- Big LED Square - 128x128. Made from salvaged 64x32 P4 RGB LED modules. Currently downstairs on the stage. Runs fully featured ft-server! Send packets to ledwall.noise. Login is pi:noisebridge272!
How to control
[edit | edit source]- Get on Noisebridge wifi and visit http://led-square:4444. Send images or text to any LED display through your browser.
- Send UDP packets per the FT protocol.
- Use a client library for C++ or Python.
Tips:
- Default patterns are set to display on low layers. If you want your pattern override this, display it on a higher layer (FT allows layers 0-15 by default).
- (0,0,0) pixels are transparent. If you want a pixel on a higher layer to be black set it to (1,1,1) or similar.
Power management
[edit | edit source]There's no need to unplug these displays at night, they use very little power. Abrupt power offs can corrupt memory cards on their controllers. When this happens reviving them may involve time-consuming re-flashing. Some displays may have an on/off button.
Many LED displays are setup to go to sleep between the hours of midnight and 8am to save a little power and calm the space.
