Getting ready to start a new project. The idea is: big, heavy lift drone + laser projector (monochrome or Rgb) must have sandisk preloaded graphix + 12v battery and inverter. The plan: fly drone and project custom light design on specific high elevation target for a minute or so. I'm calling it "aerial laser graffiti". My idea so far is to sling the projector/battery and inverter under the drone. Solenoid controlled shutter so that the projector can remain running as long as the battery lasts. Any ideas for suitable projectors would be great. The lighter weight, the better. Single diode color would work too, probably pull less current as well. I've seen a couple of Chinese models that would work, current draw seems a little high though:
Here is one model:
