# Slashbot: The Guitar Hero Robot – A robotic system capable of autonomously playing the video game Guitar Hero.

Slashbot
Slashbot – mounted guitar and the fingers (solenoid actuators).

How does it work? The brightness of a pixel from the PlayStation2′s video signal is determined by the signal’s voltage amplitude. Since the notes are the brightest images on the screen they can be detected by setting trigger points. Once a detection is made, a control signal is sent to the robot after a specific delay (determined by the tempo of the song).

# Wired.com Exclusive: Watch ‘Wanderlust,’ Björk’s New 3-D Video – Instructions on how to make 3-D glasses included.

# NI Ends Legal Dispute Over Traktor Scratch; Digital Vinyl’s Twisty, Turny History – As of Friday, it seems that the ongoing saga of a dispute over digital vinyl, beginning with the 2006 “divorce” of digital DJ titans Stanton Electronics and Native Instruments, may be over. NI released a statement Friday saying they had not only settled a US civil action patent case over their use of digital vinyl in Traktor Scratch, but had agreed to license the technology from N2IT Holdings, the US patent owners for digital DJing.

# DRUM MACHINE unplugged – YouTube video of a hand crancked drum machine. Matches are activating lever-matches by rotating the cylinder. Levermatches are kicking on several percussions. 4 Tracks.

# Dan McGrath’s Subwoofer Project – Dan writes:

I decided recently that my home cinema system could do with a nice subwoofer, and rather than buy something, I thought I'd build myself one…

# How To Make Your Own Scratchpad – How to make your own scratchpad with a pizza box and a computer mouse.

# TouchPad Midi – Started from a scavenged Cirque Glidepoint resistive touchpad (PS/2 compatible), 2×8 LCD (in 4 bit mode), two buttons and a serial Arduino board.

TouchPad Midi
TouchPad Midi – the Arduino code is available here

The buttons when pressed allow to set the Continuous Controller number by gliding the finger on the touchpad. Left for CC# linked to X and right for Y. The LCD displays the value sent in MIDI. Some custom characters where coded into the CGRAM in order to have a sort of bar graph. The first line is for X and the second for Y.

# Leon Berry’s Beast In The Basement – This organ was once used to accompany silent movies at the Lake Theater in Crystal Lake Illinois.

# Build a Pocket Theremin on the Cheap – Throw together this pint-sized light-sensitive Theremin for spooky sci-fi sound effects on the cheap.

# visual scratch :: turntablism visualized – Visual Scratch is a visualization system designed and implemented by Jesse Kriss.

# Eroktronix MidiTron – A MIDI to real-world interface designed to simplify the process of creating sensor and robotics based electronic art projects. It is easily user configurable and provides 20 terminals of digital and analog inputs and outputs in any combination.

# Hørselstest – Cool interactive hearing test. A few weeks I did a little test of my own with a frequency sweep on my dad’s cellphone. It’s scary to see what the years (and perhaps loud music) do to your ears. My uncle could only hear the sound almost 5 seconds after me and my wife heard it. Eeks!

# Super Genintari – This 4-in-1 Atari 2600/NES/Genesis/Super NES combo system actually began its life sometime circa early 2002, and at the time it only consisted of a Sega Genesis/32X and Super NES.

# Robot that listens then repeats drum beats made from lego NXT! – The program is written in NBC/NXC using BrickCC. A drum pattern is played by the user then after one second of silence the robot repeats the pattern played.

Yellow Drum Machine

Let’s Make Robots! has posted some videos of a cool robot called the Yellow Drum Machine, a Picaxe driven robot that moves around looking for objects to beat on. Whatever is beats on gets recorded and is played again.

I was sitting thinking what I should do for my next robot, what it should do.. Listening to music.. making a rythm with some robot-parts.. Thought; “Hey, I will make a robot that drives around and plays on stuff”

The Yellow Drum Machine will

  • Navigate around, collect some data, avoid obstacles, until it
  • Finds something “worth playing on” (a single isolated object or a wide flat surface that it can find an angle onto)
  • Snakes into place
  • Plays some beats on what it have found, and samples this, checking it has a “good sound”
  • Based on data collected in the area, and sample just made, then compose a little rhythm, and plays this along with the sample.

Watch the videos on the Yellow Drum Machine page to get a better idea of what this all looks like.

HydroBot Mark I – Using water to create sound

Related: , , Posted in random posts on Oct 02, 2007 - comment 0 comments

HydroBot Mark I is a robot that investigates the potential of using water to create sound and mechanical control of this classically fundamental element. Amplified metallic plates pick up the mechanical vibrations of sprayed water which is controlled by HydroBot’s spinning disks.

Future versions of HydroBot will trawl publicly available data sources related to ocean currents, waves and conditions and realize algorithmically generated compositions in water-produced sound. The often distant ocean will be linked to the space that HydroBot occupies through the sympathetic action of the ocean as measured by mechanical sensors at sea and the induced movement of water under HydroBot’s mechanical control.

HydroBot Mark I was designed and fabricated by Michael Ang in association with the League of Electronic Musical Urban Robots (LEMUR) and Eric Singer.
