I’m not entirely down with the greasy desktop pizza box aesthetic, but here’s a really easy way to make an artificial turntable input for your favorite DJ software. All you need is a pizza box, a laser mouse, some tape and a couple minutes.
A lot of DJ applications have a function that will let you manipulate a virtual turntable or scrub an audio track using a mouse. Flip a laser mouse upside down, position a rotating surface above it, and you can control the mouse input with a more familiar turntable-like interface. If you like the idea, it wouldn’t be very difficult to ditch the pizza box and work this concept into a real turntable deck.
