Tim Laursen combined a power supply, drum machine, mixer, MSA-R MIDI decoder, Darlington drivers, and a collection of individually miked, solenoid-actuated drums. The result is “Double Rainbow”, a complete mobile robot drum system.
Some technical details can be found in
this forum thread. Tim’s work also appears in this video from Sequence of Waves.
Several “makers” at the recent
Maker Faire Detroit demonstrated projects that incorporate Highly Liquid MIDI decoders. For more photos, see the new Highly Liquid Photostream at Flickr.
Chip Flynn (
Apetechnology) brought several robots, including an MSA-R controlled string instrument (background left):
Dana Dolfi demonstrated the
MSA-T controlled Great American Horn Machine:
Dave Kadlitz performed with his MSA-R & MSA-T controlled mechanical drum machine, the “Waits-o-Matic 9000″:
Michael Una performed with an MD24-synced DIY sequencer:
Steve Averill‘s robot drummer first appeared in this blog as a pair of disembodied plywood forearms.
The “Spruce Deuce” has since become
a sophisticated android drummer brought to life by 11 RC servos. Servo control signals are generated by a single MD24 MIDI Decoder:
Steve3PO, an MSA-T driven MIDI robot drummer.
Other MD24-based MIDI percussion projects are underway and
are being discussed at the Highly Liquid Forums. Have you joined the forums yet?

MD24 MIDI decoder accepts MIDI input from a keyboard, sequencer, or other MIDI controller and in response generates up to 24 independent output signals.
Each output can provide either a general-purpose on/off trigger or a PWM servo control signal.
24 x Independent 5V digital logic output
Control via MIDI note, CC, program change, and other messages
User-configurable MIDI response and PWM signal characteristics
Compatibility with RC servos
Standard MIDI IN and MIDI THRU ports
PCB-mount MIDI connectors or optional remote connectors
Output solder terminals with optional solderless terminal blocks
Standard 26-pin output header for connection via ribbon cable
The MD24 is available either as a kit or fully assembled. PDF documentation is available at the
Michael Una documented the creation of MSA-R based MIDI-controlled robotic percussion instruments for an article in the new . “Drumbot Activate!” begins on page 60. Make Volume 15
