Desert projector enclosure (courtesy of Sam):

- plastic storage bin
- clear plexiglas
- hot wire to cut hole out of storage bin for light to exit
- screwed plexiglas onto bin with nut and bolt
- another hole in plastic storage tub (slightly smaller)
  • flexible vinyl dryer tubing through this hole
  • clean air source (very high flow rate)
    • cracks in top of box is where air exits

Idea: - creates positive pressure clean air environment - keeps cool - filter and fan assembly is far from projector

Box with air filter: - HEPA furnace filter - taped trash compactor bag on one side, another bag on other side - squirrel cage blower to force air through - inflates like horrible monster - blower is loud, but tolerates lots of backpressure
