The MIDI Biodata Sonification Device v2.1 is based on the MIDI Sprout by DataGarden:
Through sampling pulse widths and identifying fluctuations, MIDI note and control messages are generated. Features include Threshold, Scaling, Control Number, and Control Voltage using PWM through an RC Low Pass filter.
(from MIDI Sprout description by Sam Cusumano)
This device has the same galvanic conductance sensing circuitry, but also features some extras:
A basic set of accessories can be selected in the product options.
By default, the options show a almost ready-to-use configuration - where everything to get started is included. (except 3x1,5V AA batteries!)
Feel free to compile the options for your needs. And let me know if there is something you want that can't be chosen!
These are not available separately yet, but I will add them soon. You can contact me for replacement parts in the meantime.
The enclosure is also available standalone: Enclosure for MIDI Biodata Sonification Device
Check this table for the default color combinations of the 3D printed enclosures:
|Main color||Button color||Light diffuser||Knob color|
Sometimes failed prints of the enclosure are available for free. These have optical defects but will work fine.
Right now: 1x black with a dirty/anthracite surface is available (for free).
If you want another combination or color, let me know and we'll find a solution.
By attaching electrodes to the leaves of a plant, or human skin, fluctuations in galvanic conductance will produce MIDI notes. MIDI notes are transmitted on Channel 1, with a maximum of 5 note polyphony (matching the LEDs).
The MIDI channel as well as the note scale can be changed using the menu:
|Threshold||red||Selectivity of the electrodes. Moving it further away from the OFF-position|
|Note Scale||yellow||Chromatic, Major, Indian and Minor scale are available. The corresponding LED flashes after entering this setting and the scale can be selected using the knob. Press button to apply and leave the menu.|
|MIDI Channel||green||Select MIDI-Channel 1-16 by turning the knob. You’ll need MIDI equipment connected to see changes. No LED effects.|
|LED Brightness||blue||Select LED effects brightness. From zero to full by using the knob. Blue LED is flashing to indicate the selected brightness. Can be used to save some power.|
A control message is transmitted on CC 80, which is also presented as a 'Control Voltage' output via an unpopulated pin headers - to modular synthesizers and equipment.
The CV and MIDI output's are the only ones available!
There is no USB connector, but an ISP header to reprogram the device with an AVR programmer - if you intend to. To connect the device to your PC or Mac, you'll need an USB2MIDI converter.
For more information about the device and usage examples check out the official forum: support.midisprout.com
The device is available as as DIY Kit with only the surface-mount components pre-soldered or fully assembled as selected by default.
These parts have to be soldered in the DIY Kit:

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
13-37.org open hardware shop was founded in 2017 by Manuel J. Domke with the mission to make open-source hardware available for the german and european market.
Luckily many great ideas are made available to the community today, instead of being put under patent laws.
While searching for useful gadgets I often stumbled upon great open-source projects which unfortunately do not get attention they deserve.
This is where we step in by supporting the inventor in finishing, producing and marketing. All the stuff to be done to make it market-ready.
Of course I'm also working on some fully self-made products which will also be released under a free license.
