Meeting Date 04/18/2009
Workshop Seminar meeting, 4 bar and adding sound
Meeting Location Elk Grove
Taught by Dan
Dan went through all the elements of a 4-bar linkage prop. Simply using a pneumatic cylinder with
a stroke of say 6-inches, your prop would move 24-inches. Dan also talked about the sound for it, the controller to control the sound and pneumatics, the trigger ( in this case a PIR sensor) and how to mount your prop and the space needed. Dan gave us a sneek peek at the controller-audio board he is building for us and he did a short welding demo. There was also some really good food. Guest writeup by Dean, pics by Shelley
