Week 2 - 4/16/2012

Gathering Parts

I've been collecting components and some tools to begin construction. - Tactile Transducer - T-amp Lap steel components: - 2x6 hardwood (Red Wood "heart") - tuning pegs

Still need a guitar pickup - there's lots of cheap single coils on ebay which I'll probably go for.

Prototype Construction

I found a cheap electric guitar (plus a bonus amp) on Craigslist for $50. The plan is to begin hacking it up and attach a voice coil to it as close to the bridge as possible.

Once I have the ability to put acoustic energy into the guitar I will start trying various patches. Some ideas I know I want to try:

- direct feedback of the signal coming out of the guitar

- harmonics of what is coming from the guitar

- driving with noise

Week 1 - 4/9/2012 - Initial Project Plan

Ideas and goals

My initial plan was to expand the performance system I developed for 220b which became Pickin' On Chuck. For this the dialog between performer and computer was the area I felt most lacking and hoped to improve upon.

I also am interested in exploring the use of tactile transducers to reproduce sound. I used these some in my 255 intermedia final project with a piece of plywood and sheet-metal mounted in a picture frame. What I really want to do is put these in a musical instrument and explore the possibilities. This concept has been inspired by a couple of instruments created by Dan Overholt:

Overtone Violin

Overtone Fiddle

To complicate matters further, I have been meeting with Bill Verplank to talk about his work with "The Plank", as a small scale, affordable haptic device for musical instruments.

To focus this a little bit I am going to begin by starting with explore possibilities of an actuated instrument using tactile transducers. I have acquired a couple different flavors of these from Parts Express. The puck and the sound exciter. These are basically the same thing except for the weight, and probably coil construction, which give them different frequency responses. These can be driven with a fairly inexpensive digital T-Amp.

Current Plan

My current plan is to build a lap steel guitar based on the plans available from BuildYourGuitar.com. Near the bridge will be mounted a tactile transducer, most likely the "Puck" since it seems to have more weight and I believe will be mounted more sturdily. I would like to be able to use the voice coil to put energy into the strings of the guitar to provide a means for mechanical feedback as well as explore other possibilities such as exciting harmonics. Depending how long the construction takes, I would love to mount a Plank on this instrument for control.

Next Step

Next step is to make a shopping list and start getting all the parts I need for construction of the instrument.
