Burning man starts on Aug 24th. When we arrive, we must have the following:
- [ ] LEDs along the exterior of the frame
- [ ] LEDs throughout the interior
- [ ] A sound system (with small speakers in the interior)
- [ ] A generator that provides reliable power
We'd like to keep the entire electronics budget below $5k

Quick math for the size of the car
- Height ~3.5m
- Length ~ 6m
- Width ~ 2.5m
This gives us a total perimiter of 17m and a total area of 59.5m^2
I've had several recommendation for waterproof WS2812B strips
Each strip has the following specs:
- $30.00 per strip (plus shipping)
- 150 LEDs per strip
- 5m per strip
- 120 degree emitting angle
- 36 watts per strip
- 2550 lumens (17 lumens/LED)
If we get 70 of them and cut them into 50 LED segments, some napkin math would give us:
- 210 strip segments (each 166 cm long and drawing 12 watts)
- 350 total meters of strips
- 2520 watts
- 10,500 total LEDs
- 178,500 lumens (As bright as about 300 x 60W halogen bulbs)
- ~$2.5k

Purchasable on Adafruit. Each one has the following specs:
- Can control up to 8 strip segments (each up to 64 pixels long, ours are 50)
- $25 (plus shipping)
If we get 26 of them it means:
- We can control 208 segments
- We have to solder 208 segments
- It will cost $720
Seems like there are four main LED sections that need power and control
- Left side
- Right side
- Front & Interior
- Back & DJ booth
In each of those sections, we should have a node. The node will contain a power supply and a USB hub, and should be protected so that it does not get damaged.
We want a powered hub with at least 8 USB ports.
We need 5V power for each of the LED strips. Micah recommends a 200W Genssi.
We should bring an old macbook, which will let us debug things on the fly. If it breaks, it will be replaceable by other macbooks. Uses 85 watts
Kan Bros have a large speaker system, I'd estimate it at 2000W
I'd like to use inverter generators because they're quiet and efficient. We already have one 3100W Champion, I think we should get a second. One will be dedicated lights, and the other dedicated audio.
