Some interesting things I found recently:

# Nudge

Hobnox has launched Nudge, a virtual-instrument widget designed for self-expressive online music making & sharing.

It’s fun and simple to use and you don’t need to know a single thing about producing music to make your own individual songs in minutes!

Brought to you by the developers of the Audiotool, nudge is yet another example of the pioneering work of the team dedicated to creating the best online music production tools.

Nudge features

  • Includes 8 different sounds.
  • 16 Step Matrix allows drawing or selecting notes with your mouse.
  • Adjust each Track Volume & Panorama to correct the mix & set the overall Master volume.
  • Tempo can be adjusted.
  • Get + Share feature sends links and emails to your friends.
  • Embed the widget on your own profile, blog or webpage.

Lots of fun, just try it below.

# Cloudspeaker – What would your music taste look like as an object? Cloudspeaker is a conceptual work to create loudspeakers that reflect the music taste of their owner via 3d printing.

# DSO nano by Seeed Studio.

DSO nano is a pocket size digital storage oscilloscope fulfills basic electronic engineering requirements.

It is based on ARM Cortex™-M3 compatible 32 bit platform, equipped with 320*240 color display, SD card capability, USB connection, and chargeable batteries. Weighs only 60g!

# little-scale: Multiplexing MIDI Output Streams with Arduino

Sebastian Tomczak writes:

Arduino can easily generate MIDI output data for use with external synths and modules or to take physical events and turn them into control data for use with software synths and applications etc.

Although the Arduino only has one Serial output, it is still possible to use a multiplexer to send multiple streams of MIDI data to multiple devices.

The idea is pretty simple. The Arduino still uses its TX pin for sending serial data, but uses an analog multiplexer to choose where that data is going (say, one of two MIDI outputs for example). The analog multiplexer that I have chosen is a 4051 and can 'route' the data to up to eight different places.



Giancarlo Todone of nerds’ headquarter posts introduces to PIC_MIDI, a homebrew solution for converting an old keyboard to MIDI.

An "open" electronic project involving a Microchip PIC 18F452, two simple and cheap de-mux 74hc138, a bunch of passive components and some software to build a MIDI master keyboard controller supporting velocity, continuous controller handling and strict adherence to MIDI protocol. Ease of setup and cheapness of required parts make this project suitable for intermediate hobbists, while technical specs such as low latency and high sensitivity to note-velocity make the device desirable for all musicians and DIY enthusiasts having an old keyboard lying around. EAGLE CAD schematics allow for quick circuit understanding and assisted production of custom PCB, while simple MikroC PIC code provides additional customizability in circuit's behaviour.

Some interesting things I found on June 10th, 2008:

# The Weather Box

Gian Pablo and Lesley Flanigan’s final project for Networked Objects.

Our original idea had been to retrieve weather information from the Internet for different cities, and use this as the basis for a simple melody. This basically what we delivered:

Gian Pablo Weather Box

The Weather Box is built into a tea box. Inside is an Arduino-based polyphonic synthesizer, with an XPort Internet access module. When dialing up one of the 8 cities, the box retrieves the weather information for that city from an NOAA server, and turns it into a simple melody.

Pressing the red button will replay the melody.

# ArcAttack – Home of the Singing Tesla Coils – Creators of the original Singing Tesla Coils, the crew of ArcAttack uses high tech wizardry to present music in a whole new light. ArcAttack employs a unique DJ set up of their own creation (an HVDJ set up) to generate an ‘electrifying’ audio visual performance. The HVDJ pumps music through a PA System while two specially designed DRSSTC’s (Dual-Resonant Solid State Tesla Coils) act as separate synchronized instruments.

# Star Wars music played by a floppy drive – Don't throw out your old floppy drives just yet!

# Evolution2 Contest – Win 3x $30,000 – Due to the overwhelming success of the first Evolution contest in Europe, we are launching a worldwide version: Hobnox Evolution2. Submit a project into one of three categories and compete for one of three Artist Support Packages worth up to $30,000 each.

# Sound Design for Imaginary Instruments: A Kore-Prepared Piano

Peter Kirn writes:

In the last installment of “sound design for imaginary instruments,” we saw some experiments with guitar sounds. This time, I’ll talk about how nice it is to be able to throw together sampled sounds and effects quickly in Kore.

# SUB SUB WOOFER – capable of reproducing sound down to 1Hz – The speaker requires installation into a purpose built attic or basement space which works as an infinite baffle/resonant chamber so you don’t actually get to see the cone of the speaker oscillating at 1Hz, but you’ll feel it.
