Beacon4 will be the fourth incarnation of the flagpole beacon (after Beacon2 and Beacon3), for Burning Man 2012. This year the plan is to take a different approach, and light the entire scaffold tower rather than just a beacon on top of the flagpole.

Project Status

  • 2012-06-07: Work on StrichLux continues. Evaluated lots of software, Lightjams is looking the best at this point, though would require Windows.
  • 2012-05-27: Completed rev. 1 StrichLux system design of all modules required for this project and sent all boards off for manufacturing.
  • 2012-04-30: Started planning the power architecture for the project.
  • 2012-04-29: Work continuing on IO-DMX module.
  • 2012-04-24: Permission received!
  • 2012-04-23: Requested permission from NeonBunny to attach LEDs to the tower.
  • 2012-04-22: Started putting together idea.

Outstanding Issues

  • Software we were thinking of using was QLC (but it only supports 4 universes) or MagicQ (but it's x86-only which means more power draw)
    • If we go x86, the fit-PC might be a good choice, it's a 6-8W x86 box in a small metal enclosure
  • As of June 2012 the leader in the software investigation is LightJams, which would be Windows on x86

Ideas/Plans

  • Main idea is to cover most of the scaffold tower in addressable LED strips, driven by multiple StrichLux modules
  • Art-Net will be used between the controller and the StrichLux box
    • Backup plan is to have a USB hub and one OpenDMX USB interface per universe, driving the StrichLux boxes via IO-DMX input modules
    • IO-DMX input module could be brought along either way and swapped to manually control the "display"
  • BeagleBone is being looked at to control the whole display
    • <1W idle, 1.75W full load
    • Comes with onboard Ethernet
  • Need to find a fanless very low power 4 or 5 port Ethernet switch
    • Allied Telesis AT-FS705LE V5 might work, it's rugged, low power (1.5-2.5W), and cheap
      • But it takes 7.5V which would be another regulator and is a potential point of failure that would bring the entire system down
    • Alternative option is the GarrettCom S14H-Hi, it takes 8-15V in via screw terminals and is ruggedized, but $140 and draws 4W
    • Best option may be the Sixnet SL-5ES-1, it's $100, rugged, takes 10-30VDC via screw terminals, and only draws 2W

System Components (out of date as of 2012-06)

  • BeagleBone (controller)
  • 4-port fanless Ethernet switch
  • 1 or 2 StrichLux boxes (transform engine/protocol converter)
  • Many LED strips (need to work out dimensions)
  • Power setup (need to work out power details)
  • Debugging terminal (XO-1?)

Power Details

  • Power requirements (peak)
    • BeagleBone - 1.75W
    • Ethernet Switch - 1.7W (assuming AT-FS705LE V5)
    • StrichLux box(es) - ???
    • LEDs - 10W/m (need to measure to confirm)

LED Details

  • Length required (very roughly until I get real numbers from Skibit)
    • Main vertical bars: 4 * 20ft = 80ft
    • Ladder vertical bars: 10 * 3ft = 30ft (but 2 of those are near ground level)
    • Rigid guys: 4 * 6ft = 24ft
    • Ladder rungs: 8 * 4 * 1.5ft = 36ft
    • Total: 170ft (plus probably want a bit extra just in case, so 11 strips or 180ft)
    • That's 1760 LEDs and 550W peak!

StrichLux Enclosures

  • Each StrichLux controller with its 4 output modules, 1 input module, and 1 power module will need an enclosure of some kind.
    • Pelican case? Could do one larger one with all 3 controllers in it, or 3 smaller ones
    • Assuming each StrichLux box has its own enclosure, would need a bunch of connections made through it:
      • Power - 2x12V @ 20A each - 4 20A power pins
      • Ethernet input - RJ45 - 1 RJ45
      • Strip outputs - SPI+5V - 2 signal pins, 2 10A power pins each x 4
        • JAE SRCN2A16-7S/7P would be good and extremely rugged, but the cost may be too high

Test Equipment

  • Want to be able to power the whole setup from AC power for configuration/testing/programming
    • ATX power supplies provide plenty of +12V which could feed the PWR-DC5 modules
      • A modular supply like the OCX ZT-series would be cleanest, could modify the cables with Sabre connectors on the ends
      • Need 100W per channel, 200W per board, 600W total @ 12V
      • 100W per channel @ 12V means 8.33A
      • PCI-E and 8-pin CPU power connectors on ATX PSUs provide 6 amps per pin
        • PCI-E connectors have 3 pin pairs each
        • 8-pin CPU power connectors have 4 pin pairs each
      • Need four pins per board
        • Two boards get 8-pin CPU power -> Sabre connectors
        • The last board gets a 2xPCI-E power -> Sabre connector
      • OCZ ZT-series 750W power supply has all the required connectors
