Electronics Technology II: Digital Final Project Week 4

Project Proposal:

Project Title: BE5 Multi

Project Description: 
   My project is an on-board 5-sample looper for the guitar. It will be built onto the interchangeable pickguard that most guitars utilize so that it can be easily dropped in to any guitar. It will include 5 switches to control the loops and an one switch to control all the loops together.

Parts List:

• 6 SPDT panel mount switch *
• 6 normal-off panel mount buttons *
• 6 green panel mount LEDs from Mouser Electronics http://www.mouser.com/Search/m_ProductDetail.aspx?Lumex%2fSSI-LXR3612GD%2f&qs=sGAEpiMZZMsUguuR3b6UZi3FgsitOqB%252b7rKl%2fpAndtg%3d

Weekly Goals:

1. Learn Ableton and build Loop session to accept teensy Midi and
applicable controls and write Arduino code

2. Build prototype circuit on breadboard and begin debugging/troubleshooting

3. Finish debugging/troubleshooting and begin to finalize circuit on blank PCB

4. Mount circuit on PCB and mount project on the guitar.

5. Finalize aesthetics and practice performing

   There is a similar device to mine called the Guitar Wing by Livid Instruments. I clips onto the bottom horn of the guitar and is a fully programmable MIDI controller tethered to the computer. My project has some of the functionality of this device but is more streamlined and built in to the instrument. In addition, my project has the potential to be DSP controlled and break its tether with the computer. Here is a link to Livid Instruments' website: http://shop.lividinstruments.com/guitar-wing/
   In the same way, my project will be similar to the ET II final projects of Travis Fodor and Malakai Linden, but as with the Livid device, my project is currently only loop-focused and has potential to be powered by internal DSP rather than MIDI and computer connectivity.
