Meet the Video DJ Machine

Have you ever wanted to perform as a DJ but found the equipment expensive as well as intimidating? Well, your prayers have been answered by [Dror Ayalon] who has designed Nomnom 2. It is an open source, music mixing project that uses up to 16 video clips to give you control of your next hit album.

You are given charge of a physical control panel that has 16 buttons and four knobs. Each button can be used to turn on or off a particular clip while the knobs control the repetition rate, volume, speed and playable length of each track. An Arduino sits under the buttons and is responsible for sending the information to an application that runs in your web browser. The browser app uses the NexusUI library to control playback of the audio clips and bring to life the entire experience.

[Dror Ayalon] has been busy polishing his project and there are some neat videos of him demonstrating it so check out the videos below. The code is available for down from GitHub and the BOM is available at the project page. The web app can be ported to a desktop app using electron and a PCB can be designed for the controller for future versions.

For now, it is incredible to see hardware and software, come together in such a harmonious fashion. This may be the start of something wonderful but if you are just looking for a way to annoy the neighbors, check out the Midi Musical Siren instead.

PC Fan hack lets you scra... scra... scratch analog audio, ah-yeah (video)

Digital DJ controllers let would-be grandmasters get up to all sorts of fancy new tricks, but if you're one of those old dogs who can't be taught, then this PC-fan-come-DJ-turntable might tickle your fancy. Connected to an old-school personal cassette via an Arduino, with a little voltage level smoothing in the mix, moving the fan "scratches" the audio, by controlling the speed of the tape player. The initial plan was to have the fan spinning with the music, like a real turntable, but as you'll know if you've ever caught your finger in one of these things, it's probably best it didn't work out. Despite its home-made charms, one final flourish is VU style LEDs for some mixer-style visual feedback. Alas, there's no built in cross-fader, so don't start work on that DMC routine just yet.
