QLab serial projector control with AppleScript

If you are using QLab for video cues, I suggest having it triggered by the light board as most projections need to be synchronized with lighting. That way projected scenery will fade in and out with area lighting during scene changes. It is fairly easy to connect a USB MIDI interface between the Mac and the "MIDI OUT" of your light board.

Pneumatic Jack in the Box, Part 3

To support the mask I built a frame out of perforated metal tape. I basically fit each piece into the mask from the inside, then attached the pieces together with small nuts and bolts. The frame was then screwed into a stand made of three pieces of 1x2 wood left over from the torsion box coffin lid project.

Make sure you view all the videos posted in Part 1 before continuing.

The ELK-120 sound board can pull up to 2A@12VDC and the mouth servo may require more current @5VDC than the Arduino's voltage regulator can support, so I went with a dual-output power supply that provides 12VDC and 5VDC outputs.

However, the Arduino and the DF Robot Relay boards all need 9VDC.
