About This File
Please see three angles of my item plus one image of the item that inspired me.. I know, what I did kinda pales by comparison, but fear not - I am just getting started. My buddy can cast it into metal for $100. The idea is you clamp a contact mic (the Korg model $15 is the one I'm looking at) and then you stroke it with a violin bow ($17 at Amazon with rosin). and send the contact mic output to a mixer ($50 at Amazon) which sends it over USB to the software (ChucK) that will enhance the sound and send it to the speakers.
So yeah, it's an $80 price tag on gear to run this rig. Still, it's nice because it should produce some exotic sound due to it's unique design. Also many other shapes are possible. Have to stay within a six inch box for the metal pours though. The one shown is in an 8 inch box (the ultimaker) so it must be a touch smaller. Still, a wide variety of designs are possible. This simple one is just for starters.
