Thanks for the quick reply. I am a juggler (http://nizer.com
). At the beginning of my show I play a video of me hang gliding and juggling. I drop a ball "by accident", land as fast as I can and run on stage and catch the ball I dropped. It is released from a tin can with the bottom cut out that is attached to the ceiling with a pin thru the bottom and a string. When the string is pulled the ball drops.
I am now using Qlab, DMX and Bluetooth to run all lights, video, sound, midi, video dowser and the only thing left to automate is the ball drop. I want my mac (hopefully via Qlab) to tell a fully wireless device to drop the ball from the ceiling. The computer is about 50' from the ball drop and usually line of site. I want to use a easy to find battery power supply and bluetooth since that is already built into the MacBookPro.
I would be OK with 4 AA batteries. The BT shield looks perfect with a UNO. Can they both be powered via the 4 AA batteries. What else would I need to power the Servo. What else do I need to get to make this work.
I fly for 90% of my jobs and my luggage is already close to the limit. I can only travel with 1 pair of underwear ;-). SIMPLE - LIGHT - RELIABLE.
THANK YOU SO MUCH
