How-To: Make a solid-state A/V switcher
Engadget has posted a great how-to for building an A/V switch box.
While “solid state” may bring bring to mind electronics from the 60s (or, in some cases, yet-unreleased flash hard drives), but in this case it simply means the actual switching is done with circuitry, not mechanically. Ironically, the circuits are activated with a mechanical switch, but they could be controlled electronically if you were so inclined.
In this How-To we’ll show you how to wire up your own A/V switcher which you can expand and use any way you’d like, for composite, S-Sideo, component, even VGA signals. Sure, you can buy a newer, really expensive TV’s with multiple inputs (even component), but for those of us whose credit cards aren’t quite up to that challenge, more inputs for less cash would be rather desirable. Let’s get started!
