Halloween Props: Talking skeleton in reaper robes

Mike Szczys — Wed, 27 Oct 2010 17:00:44 +0000

Here’s a great way to guard your front door on Halloween. [Sam Seide] built a motion controlled talking skeleton. The electronics are fairly straight forward, consisting of an Arduino, WAV shield, PIR motion sensor, servo motor for the jaw, and a couple of red LEDs for the eyes. But [Sam] did some really neat things in the design of the skeleton itself. As we saw with the puking pirate, he built the body out of PVC so that he can take it apart for easy storage. Under the reaper robe you’ll find a set of powered computer speakers that connect to the WAV shield. The servo motor is mounted in the skull and moves the jaw using a small wire arm. Since the whole thing is a bit flexible (thanks to the PVC), the torque of the motor causes the skeleton to move around, adding a touch of life. Don’t miss the well-made video walkthrough after the break.

New Nintendo DS homebrew music apps

The Nintendo DS homebrew scene is heading into a heavily musical interlude with a few new apps. This is good news for anyone who liked Protein DScratch but wanted more options and functionality. More information after the break.

The second is a program called dsmcu; it doesn’t make music itself, but is designed to control an external MIDI program or device via WiFi. As the name implies, it uses the mcu protocol to send and receive fader data, display live VU meters, control tracks and volume, and scrub. It is currently in beta and only works with Reaper and DSMI, but the developers are confident that they’ll get Logic and Pro Tools working with it soon.

We don’t expect you to use these as a substitute for Korg DS-10, the commercial Korg synth emulator for the DS. Rather, when used in along with it, these programs make the DS into a surprisingly potent tool for making and mixing music.
