Update #1: Getting Started with a Prototype

  
  One of the most important parts if not the most important part of the our magnetic resonance guitar is the magnets themselves! So, a simplistic prototype of our model was created with some parts laying around. By wrapping wire around six different steel rods and surrounding them with metal which acts as a sort of heat sync, we have created our first electromagnet that mimics what a magnetic pickup would look like on a guitar.

  Just to start, we are working with one electro-magnet. Since each guitar string resonaces at a different frequency, each of the electro-magnets need a specific amount of voltage. This is somewhat tricky to accomplish without the use of a micro-controller. Our plan is to use a micro-controller along with 6 transistors to regulate the amount of voltage for each magnet thus regulating the frequency for each string. Below is a sample of what we can accomplish sound wise with our design. However, it becomes trickier to deal with multiple magnets. For now, we will stick with one magnet and work on building a general circuit on a prototype board.

                         
Resonating Low E- String: (82.8 Hz)





  As you can see, it is possible to create a loud, distinct sound just with a magnet. Power will definitely be an issue when it comes to supplying the magnets. One of the guitars we will be using will have a built in tuner so it may have to be taken out to place in our circuit or to allow wires from a power supply for said circuit. This will be easier to deal with than creating a mount for the circuit on the outside of the guitar.
