Wired remote volume control for ClearOne Gentner AP800 matrix mixer

How to use the Arduino microcontroller to remotely control this matrix mixer.

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.

Pneumatic Jack in the Box, Part 1

This year's new prop is a large Jack in the Box - a two foot cube, powered by the Arduino microcontroller. It will have an Insteon InlineLinc relay module inside so that the prop can be controlled with a hand-held remote or an Insteon motion sensor. When the Arduino sees that the InlineLinc has been activated, it will execute the following sequence of actions:

1. Turn on a spotlight aimed at the prop so people pay attention to it
2. Spin crank handle (powered by motor) while playing a sound effect
3. Open the top lid
4. Pop up a large scary clown head
5. Play a sound effect while moving the clown's lips with a servo
6. Lower the head
7. Close the lid
8. Turn off the light
