OpenPipe Breakout

OpenPipe Breakout

Have you ever dreamed to make your own electronics flutes or bagpipes with Arduino? The OpenPipe Breakout is the first capacitive sensors interface with flute/bagpipes layout to help your dreams come true.

  • 12 capacitive finger sensors available (7 in the front & 5 in the back)
  • Black plastic pipe & aluminium finger sensors
  • Four wires I2C connection cable (VCC, GND, SDA & SCL)
  • MOLEX 4pin female connector
  • 240 mm length & 13 mm diameter
  • Arduino library & examples available
  • Based MPR121 touch sensor controller

Examples

iPhone 4S  and ThumbJam

In this example we connect the OpenPipe Breakout to iPhone 4 using our MIDI-USB Shield and a Camera Connection Kit. The Arduino send MIDI commands to the iPhone running ThumbJam, a great synthesizer for iOS.

Arduino Musical Shield

In this example we connect the OpenPipe Breakout to Arduino using Arduino Musical Shield for MIDI synthesis.  Just send send MIDI notes from the Arduino to the shield, connect headphones or speakers to the shield jack audio output and  enjoy!. Code here.

Audio Codec Shield

In this example we connect the OpenPipe Breakout to Arduino using Audio Codec Shield for high quality audio output. GHB and Säckpipa samples are used to demonstrate Arduino sampling skills. You can find detailed information on this example in this blog post. Code here.

PWM output

In this example we demonstrate basic audio output from Arduino using PWM. You can find detailed information on this example in this blog post. Code here.

 

Connections

The OpenPipe Breakout I2C/Wire interface allows connection with any microcontroller with I2C interface.

Development

Attribution

This work could not be done without the work from others: Arduino for such great creation and SparkFun for the inspiration.

I want one!!!

    I will buy this for my fluxamasynth!!!!!!!!

    hi, i made your openpipe, but the sound is a little different from yours. it’s less realistic. the drone is almost inaudible. i have it connected to an amplified speaker. if i make a low pass filter could i fix the openpipe to have more realistic note tones and drone?

    Does anyone know if there is a source for the OpenPipe Breakout (or at least the breakout board) in the US?

    • OpenPipe Labs.

      Hi FIsk!
      We have sent several OpenPipe Breaout from Spain to several places in US without problems.
      There is no source apart from us 🙁

    Has anybody tried to build it using a stm32 with dds?

    Hi, Does anyone make Openpipe?

    What is the use of this instrument? Contacts, configuration of sounds and fingering?

  • James Darrah

    I’m trying to get the openpipe breakout working with a teensy 3.x and am getting an endTransmission error that I’m told may be related to the pull-up resistors you use on SDA and SCL. I found a schematic on your old site that said they should be 10K. When I measure with my ohm meter they read around 1.7m when I check between the connector VCC & SDA / SCL. Does the new model still have internal pull-up resistors? Should I see 10K at the connector?

    • Hi James. As you already know 🙂 the SDA and SCL colours were wrong in this page. Now its fixed.
      SCL is GREEN and SDA is WHITE in the last breakouts batch (v2). The new model has still internal pull ups. Sorry for the inconvenience.
