1. Progress Report: 1/26/11 Anna Goncharova Brent Hoover Alex Mendes

2. OpenCV – Progress Hardware – Microcontroller use no longer possible – Pan and tilt mount powered by servo motors instead of mirror galvanometer/laser lightshow

3. Laptop Controller Laser pointer Pan and tilt mount Servo motors Relay Power source

4. Will the controller fit the servos? – We think so How about a pan and tilt unit with a built-in controller? – Most such units cost more than $200 and are used for security cameras What will the speed be? – Assume a distance from the secondary laser to the secondary screen of 6 feet – The proposed pan and tilt system moves at 60 degrees/0.16 second, which translates to 10 feet/second

5. How will the laser be turned on and off? – The laser will be manually connected to an external power supply. A relay will be inserted in this power line. The proposed relay has a USB connection, allowing the laser pointer to be controlled from the laptop. http://www.brighthub.com/engineering/electr ical/articles/83286.aspx?image=103839
