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.
Contents
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 evaluation:
- QLC
- Max of only 4 universes, which rules it out
- MagicQ
- Very complex and more geared toward theatre setups than VJ setups
- Supports up to 16 universes over Art-Net
- x86-only
- Advanced features like sound-reactiveness or remote control require a very expensive license dongle
- Lightjams
- x86/Windows-only
- Supports up to 16 universes over Art-Net
- Sound reactiveness, remote control, Wiimote control, and everything else is included for a low price
- QLC
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
- Fit-PC 2i is being looked at to control the whole thing
- As nice as ARM would be power-wise, x86 will be much more flexible software-wise
- Need to make sure it will be powerful enough before we order
- 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
- Allied Telesis AT-FS705LE V5 might work, it's rugged, low power (1.5-2.5W), and cheap
System Components
- Fit-PC 2i (controller)
- 4-port fanless Ethernet switch
- 3 StrichLux boxes (driver, each with:
- 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)
- Fit-PC 2i - ???
- Ethernet Switch - ???
- StrichLux box(es) - ???
- LEDs - 10W/m (~1.8A/m at 5V measured, so 10W/m after losses is reasonable)

LED Details (out of date, being replaced with below section)
- Length required (very out of date, need to update w/ 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!

- Top-Middle Rail: C * 2 = 14ft
- Toe Board: B * 4 = 10ft
- Total: 202ft? / 61.5m?
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
- Connec has plastic bayonet-style IP67 industrial Ethernet connectors which are somewhat reasonably priced, so far this looks like the best option even though it is a lot more expensive than regular non-weatherproof Ethernet
- Strip outputs - SPI+5V - 2 signal pins, 2 10A power pins each x 4
- JAE SRCN2A16-7S / SRCN6A16-7P would be good and extremely rugged, but the cost may be too high
- Need inter-strip connectors too
- Molex MX150 or Amphenol ATP connectors look good, sealed high-current automotive connectors that aren't too expensive
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
- ATX power supplies provide plenty of +12V which could feed the PWR-DC5 modules
