Arduino, iPod and RFID make beautiful, handicapped-accessible music together

Wednesday, October 5th, 2011

Terrence O’Bien posts a clean music interface (no menus / no buttons)  based on RFID, as previously seen some time ago.

There isn’t actually much new about this awesome DIY project, but it’s the way it brings the various parts together that has us impressed. Designed by Instructables user XenonJohn, with help from software developer David Findlay, the Magic Music Table RFID was designed to let a disable child (or other such handicapped user) select albums to play back from an iPod touch playlist. The iPod is connected to anArduino, which tells the device to start playing a particular track based on a selection made with RFIDcards. The whole setup is built into a coffee table and the RFID tags are sandwiched inside clear plastic blocks with the album art. You can see it in action in the video after the break and, if you’ve got the patience and skill, you can build your own using the directions at the source link.

Listening To The Walls’ Whispers

Wednesday, September 7th, 2011

[Pierre] shares an interesting geo-localization project of sound, narration and  culture,  made in  ”plan d’Aou”, a district of Marseilles – France. The project dates back in September 2010, within the framework of the Smala project in order to trace a sound cartography of Islam in the city of Marseilles: the guys at [Echelle Inconnue] took their time to fully document the all project with schematics, codes, fritzing diagrams and so on.

Several mobile systems were distributed to the people to accompany their walk across the district with, by hand, a kind of speaker to be press on the walls which makes it possible to listen to the sound by vibrating the material of the wall.

The materials of urban furniture or buildings become the speakers required for sound diffusion. Each resonant body had its acoustic specificities, the words take shape in metal, wood or glass… Textures of the sound fluctuate from a surface to another and the listener must juggle with these characteristics to obtain a quality of optimal listening, between documentary in the walls and poetic sound creation.

Serenading with Arduino

Tuesday, August 30th, 2011

This is for the uber-cool geeks who want to specially set up a pre-dinner concert for their loved ones.

Using an SRF05 and an Arduino Uno get that beautiful musical effect with the perfect smile!

Also get the code from Github, plug it in, load the sketch and play!

DIY Fabric Speakers

Sunday, February 27th, 2011

Interesting DIY fabric speakers from Hannah Perner-Wilson:

Making a speaker is much easier than you’ve ever imagined, and what you need to prepare is merely: textile (or paper), conductive tape and some strong magnets. Try this one made by Hannah Perner-Wilson and you’ll find it quite impressive.

UPDATE: as Tara commented below, you can have more information about Hannah’s work on her website Kobakant.at

Arduino To Ableton Live Via Pure DataArduino To Ableton Live Via Pure DataArduino To Ableton Live Via Pure Data

Thursday, December 2nd, 2010

 

[Spencer] built a controller sending serial data to Pure Data using Firmata Library. The data is processed and sent to Ableton Live via Midi:

It’s still unfinished here. It’s basically opening the communication between the arduino, scaling everything from 0-127 to be compatible with MIDI, then being routed through various CC’s to mac’s IAC driver, which passes the MIDI CC’s into Ableton Live.

So there you have it. A few things are missing, the LED’s still need to be added and tweaked, a problem with there not being enough power to illuminate the very demanding buttons, although I plan to resolve this with an external DC adapter though.

Cheap Fat and Open RevisedCheap Fat and Open RevisedCheap Fat and Open Revised

Monday, November 8th, 2010

 

As you can read up from [jacob sikker]‘s thesis blog, Cheap Fat and Open project is being revised and updated.

new edition has bugs fixed from 1st version, larger screen (16×2 characters) and i’ve added an op amp with bass boost and distortion feature, design by blushing boy, AKA david cuartielles. taken from his smapler board.

a few extra design goodies have been added, like walkman-like volume control, and a pixel ghost for extra prototyping.

i am only making 25 pcs. some will be sold at piksel, some at MFRU. pre-order yours today!

thanks to david gauthier for helping out with the more tricky parts of eagle CAD.

Arduino and MIDI: AVbrain’s worklog

Wednesday, September 29th, 2010

 

Even if you can find many projects using Arduino and MIDI, not many of them are so well described as [zambari] project. The AVbrain controller was developed to stay on top of a complex AudioVisual Hardware scenario.

Found (and supported from day one) on [vjforums], The AVbrain feautures:

- Following MIDI clock
– Recording and playback of 40 note long MIDI sequence
– Sending custom strings of MIDI messages in sync with MIDI clock including:
– CC information to fade video on Edirol V4 (synced to PAL)
– CC information to fade output on Edirol V4 (synced to PAL)
– CC information to fade video layers on Korg Kaptivator (synced to PAL)
– NoteOn data to trigger light flashes via MIDI-DMX converter
– Triggering audio loops on Korg ESX1 so they could be longer than the pattern played on ESX
– Triggering AR and Filter envelopes on Sherman Filterbank
– OneKnob functionality extending Korg ESX1′s ability to only control one part at time. With AV-Brain you could learn a NRPN message, assign it to a knob and use independently of device’s state.
– Fade up or down relative volume of all the channels on ESX1 – Filtering MIDI messages
– All sequencer tracks can be synced to 1/16, 1/8, 1/4, 1/2, 1, 2, 4, 8, 16 or 32 beats
– All sequencer tracks can be re-synced manually and still follow the tempo (to compensate for video delay)

Daft Punk helmet project recap

Monday, July 26th, 2010

Amazing Daft Punk helmet replica from [Volpin Props]. It took a long time to came around a wonderful replica of the famous iconic helmet used by Daft Punk. The lighting is powered by Arduino.

Its been a long road. Seventeen months, countless hours, multiple dead ends, hundreds of lessons learned, and one helmet made. In the past two installments I’ve discussed sculpting, resin casting, chroming and vacuum forming. This is where the magic happens though… Illumination.

More on Arduino Synth

Thursday, April 29th, 2010

Some time ago we posted an odd video about an arduino-based synth. [DeFex] (arduino forum user) revealed a nice PCB design to get it shielded:

The arduino is a 4 oscillator phase accumulator, and does a few other things.

each oscillator has a separate DAC which are mixed in the analog realm (controlling an 8 bit DAC level with another 8 bit signal gives a lot better resolution than changing its level digitally)

The levels of the DACs are controlled VIA PWM > 4 pole filter > Vref. and then the DAC output is level converted to +- rather then +

Each pair of DACs has another 4 pole filter on the output to eliminate any aliasing.

And yet another 4 pole filter on an aux envelope out.

There are 2 Multiplexers (completely copied from the mux shield) which get the values for 32 potentiometers which control various modulation and wavetable selection etc.

There are no voltage controlled filters on board, but it can output envelopes and triggers for modular synth filters/analog envelope generators

And 2 inputs for external control voltages through a special ADA4091-2 op amp which can take +_25v over the rail input, and being powered by the arduino power, it automagically protects the inputs from the higher voltages existing in a modular synth (+- 15v)

I am planning to make a cut down version which would fit on a proper shield, but i still need to experiment a bit (especially trying to make a nice sounding 5 volt voltage controlled filter!) but it will still have to be a mega.

I will continue posting as it is built and tested along the way.
so far i attached the arduino and made sure the signals and power are going to all the proper places.

Arduino Ant Farm

Wednesday, April 28th, 2010

Amazing project from [Adam Franchino], via [MAKE]

I went to the RobotFest / Mid-Atlantic Mini Maker Faire yesterday. I saw this awesome project and thought you might like to put it on the blog. Basically it’s an ant farm with optointerrupts. When the ants walk through the lightpath, they modify the audio output. The maker’s name is Adam Franchino, and he was there with some of his classmates from the Maryland Institute College of Art (MICA) His website is adamfranchino.net.
