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
- 2012-06-24: LED strips all obtained. Lighting design continues, as does firmware development.
- 2012-06-17: Hardware bring-up and firmware writing continuing. Lightjams is almost certainly going to be the software of choice. Lighting design is coming along.
- 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:
- Theatre-type systems
- 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
- VJ-type systems
- Lightjams
- x86/Windows-only
- Supports up to 16 universes over Art-Net
- File format is XML, so a lot of setup could be programmatically generated
- Sound reactiveness, remote control, Wiimote control, and everything else is included for a low price
- May not be able to switch programs/grids by timer, could possibly implement via macros?
- Patching-type systems
- Max
- Isadora
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
- 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
System Components
- Fit-PC 2i (controller)
- 4-port fanless Ethernet switch
- 3 StrichLux boxes (driver, each with:
- 60m of LED strips
- 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)

Lighting Layout
Random Notes
- Decided on 60m length total (3 StrichLux boxes)
- That's 1920 RGB LEDs and ~600W peak!
- Will need to come up with a lighting layout/design that will fit within this

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
- Will use M12 ethernet connectors (either from L-com or wherever else we're getting connectors) rather than RJ45s as they're cheap and IP67
- Not RJ45-compatible, but an M12->RJ45 cable will be brought for troubleshooting, and they're not expensive
- 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
- Amphenol SINE MotionGrade M23/M40-series connectors look really nice, aren't too badly priced (compared with 5015 connectors anyway) and are weatherproof
- They're really tall though, sticking out would negatively affect durability, so RT360 connectors might be better (but a bit more expensive)
- Pricing is Receptacle, Sockets, Plus, Pins, Grip/Shell (* 4 per box * 3 boxes)
- SINE M23: (6.46 + 0.728*4 + 8.430 + 0.640*4 + 3.61) * 4 = $95.88 * 3 = $287.64
- SINE M40: (8.09 + 1.660*4 + 11.05 + 1.780*4 + 7.83) * 4 = $162.92 * 3 = $488.76
- SINE RT360: (4.85 + 0.351*4 + 12.28 + 0.351*4 + 6.62) * 4 = $106.23 * 3 = $318.69
- Molex MX150L will be used for inter-strip connections
- Reasonably priced
- Tooling is reasonably priced
- Matte sealed

Test Setup
- 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
