Where? Radio Shack.
I just received a Eyeclops mini projector and hope that i can use it with my computer(project whats on my computer screen). The only ports on the projector are composite AV inputs, the standard white, red, and yellow. My computer has HDMI, USB, and firewire, S video, and an extra monitor port. What would be the best(or cheapest) way of making this happen?
