[SML] Looking to build a dowser for an office projector, simple and cheap

[PJ Veltri]

You can also easily adapt the servo/DMX method to be a Servo/Raspberry Pi
that can parse OSC fairly easily so you can control your douser in your
projection control (Qlab in my case). I rigged one up for a show that I was
doing last year for about 60 bucks but we ended up scrapping it due to no
need for blackouts in the show.

If you're interested I can forward on my code for the pi.
