Episode 2 of the continuing story of the Dulcimer powered b Littlebits.
See episode 1 for the making of the 3-string dulcimer that is used in this project.http://littlebits.cc/projects/bits-on-a-string
a strange sound ! In this episode the dulcimer strumming is done with the
vibration motor, pulsed by the trigger output of the micro sequencer. It is
motion controlled with a dimmer. The vibration motor moves back and forth,
driven by a servo to be able to touch all three strings. The servo is also
motion controlled with a dimmer and pulsed by the same micro sequencer (with
only pulse 1 and 3 ON) and a latch. The sound signal from the pickup elements
is amplified via the echo delay bit and sent to the synth speaker (done for a
nicer sound) and it also triggers the MP3 player with a second synth speaker,
loaded with many different short percussion sounds.
