Using A Hammond B3 To Send Coded Messages By Ham Radio

Here’s something Jimmy Smith never tried – using a Hammond B3 organ to send coded message via HAM radio.

Forrest Cook developed Tonewriter – an experimental system that uses an Arduino and a Hammond B3 organ to encode text as a series of audio tones. The messages can then be displayed on a spectrogram – used by ham radio operators to visualize the audio that is received by a radio receiver.  Continue reading

Use A Microsoft Kinect As A MIDI Controller

YouTube Preview Image

Kinect MIDI Controller is an open source project designed to let you use a Microsoft Kinect as a MIDI controller.

The the project uses Microsoft Kinect SDK to track the skeletal data.

The Kinect SDK provides the logic to detect the X and Y Co-ordinates of a user’s hands. The X & Y Co-ordinates are then scaled and converted to MIDI messages. These MIDI messages are then sent to the MIDI output port. The tool contains a .NET Wrapper for the MIDI interfacing methods provided by winmm.dll Win32 API.

Details are available the project site.

KOELSE Documentary – Making Music From Junk

YouTube Preview Image

KOELSE is a documentary is about four young men, who form a group called Association of Experimental Electronics (KOELSE). They gather electronic devices that others throw away and build musical instruments and art installations from this “waste”:

Their opinion of music, fun and the culture of consuming differs from the masses. What others see as a worthless piece of junk is valuable technology for them. Their whole idea is based on the idea of reusing this garbage.

KOELSE is not really a band, it´s also not really an art community. It´s more like a way of life that relies on working together and using the old technology again.

According to the group, their opinion of music, fun and the culture of consuming differs from the masses. What others see as a worthless piece of junk is valuable technology for them. Their whole idea is based on the idea of reusing this ‘garbage’.

Can The $70 Leap Motion Controller Succeed Where The Kinect Failed?

Developers have announced the Leap – a new $70 motion sensor that they say is ‘two hundred times more accurate than any product currently on the market.”

Like the Microsoft Kinect, the Leap is designed to translate your gestures and movement into computer control. But the developers suggest that the Kinect is a toy, compared to the Leap:

This isn’t a game system that roughly maps your hand movements.

The Leap technology is 200 times more accurate than anything else on the market — at any price point. Just about the size of a flash drive, the Leap can distinguish your individual fingers and track your movements down to a 1/100th of a millimeter.

 Here’s a video introduction for the Leap:

Awesome Oscillographic Synthesizer, de/Rastra, Made From Old TV

YouTube Preview Image

Here’s another cool project from Kyle Evans, creator of the electroacoustic didgeridoo.

The de/Rastra oscillographic synthesizer is a real-time audio/video instrument and computer-interfacing device that lets you generate visualizations intrinsic to cathode ray tube technology while simultaneously creating the acoustic analog of the displayed imagery.

Here’s what Evans has to say about the de/Rastra oscillographic synthesizer:

Through hacking and exploiting the capabilities intrinsic to all CRT devices, the technology becomes repurposed as a performative interface, breaking down the device’s ‘consumption only’ nature. The performer is given control over the technology by removing it from the intended application and forcing it into an active state through a combination of physical and mental effort.

Meet Limor Fried – Creator Of The Roland TB-303 Clone x0xb0x

Make Magazine talks to Limor Fried, the creator of the Roland TB-303 clone x0xb0x, in the latest Make: Shorts:

Limor Fried is the founder and engineer behind Adafruit Industries which makes electronics kits that teach soldering, tinkering, and technology exploration.

One of their projects, the Tweet-a-Watt, is a wireless modification to a common off-the-shelf home energy monitor, the Kill-a-Watt. The Tweet-a-Watt not only monitors your energy consumption, it sends the information to Twitter so you can track it online, which reveals usage trends over time. Besides selling a Tweet-a-Watt kit, Adafruit has also put the open source plans online for all to freely build and share, creating a network of makers watching their usage and swapping energy-saving tips.

While the focus is on the Tweet-a-Watt, it’s still an interesting introduction to Fried and her approach to electronics DIY.
