Hello bitsters --
I've been trying to come up with a way to trigger bits (lights in particular; sequencer bit, bright LED, long LED and bar graph) whenever I hit a conga drum.
My first attempt was using the sound trigger bit - but that gives an 'on' signal for a couple of seconds - so not responsive enough.
Second attempt is with the microphone bit -- I'm gonna mount it up underneath the conga head. I had to make my own wire bits to have enough length to go from the powerbit to the lights bits (mounted on a mount board outside the drum shell near the top of the head). I had to experiment with the length of the homemade wire bit because I was getting signal loss. So far it's working and sensitive enough ... but I'm thinking there's a better way using:
a modified pressure sensor (with a piezo vibration sensor soldered in instead of the sensor):
or the new makey makey sensor taped to the drum head and my ankle or other exposed skin (not my arms or hands cuz I need them to play).
Any thoughts? In particular if there's a better way to sense the vibration of the drum head to trigger lights bits?
I may go another route and try a highly focused motion sensor to sense when the drum is hit by hand ...
