Thiago Avila and I are building a Smart Projector for our final mechatronics project. We are going to measure with a web cam where the screen is using image detection techniques. Then, use a PSoC controller, RS232, the Cypress CY3210-EVAL1, a servo, some motors, some fans, a laptop, a fresnel, a very bright light & ballast, a special lens, and a LCD monitor he tore apart to build an auto-focusing, auto-keystone correcting, home made theatre system.
We named it Hector, The Projector. Stay tuned.
