The AVR Guitar was well documented by both picture and video from start to finish. Use this page to navigate through all our documented multimedia. The order is chronological and all media is described with captions.

Figure 1: Shown is a video introduction of the AVR Guitar project.

Figure 2: Guitar used for design: Fender Stratocaster (Squire) shown with the fret board separated.

Figure 3: Shown is the first few LED cathodes tied to together at a common ground node.

Figure 4: Shown is the first few LEDs tested for sizing on the fret board.

Figure 5: Shown is the fret board after drilling for implementation of the LEDs. The combination of the brittle rosewood neck and an excessively large drill bit that was required damaged the neck beyond repair.

Figure 6: Shown is a video addressing the fret board issue.

Figure 7: Continuing to strand together the LEDs while brainstorming new fret board options.

Figure 8: More stranding...

Figure 9: More stranding...

Figure 10: It was decided that due to cost restraints, purchasing a new guitar with a different kind of fret board wood was not an option. Shown here is a particle board "fret board" construction to simulate the guitar fret board as best as possible.

Figure 11: A more detailed particle board shot.

Figure 12: Shown is the beginning stages of soldering and hardwiring of the LEDs into the new fret board. This side would be embedded into the actual guitar neck and out of site by using a pre-mapped wiring PC board, which wasn't applicable to use based on the simulated particle board model that had to be substituted.

Figure 13: Another shot taken from the side view.

Figure 14: Shown is the frontal view with the embedded LEDs facing outwards on the "fret board" side.

Figure 15: Shown is the completed fret board, 12-position rotary switch, 7-Segement LED, and micro controller wiring.

Figure 16: Shown is a close-up shot of the simulated "body" of the guitar, which would also be embedded inside the guitar body. Houses the micro controller (center), rotary switch (bottom right), and, for this application, a transistor breadboard circuit (left). The transistor circuit can also be simplified to electronic chips or IC (Integrated Circuit).

Figure 17: Another shot taken from the side view.

Figure 18: Shown is the beginning stages of the transistor circuit needed to illuminate multiple LEDs from single output pins on the AVR microprocessor.

Figure 19: Shown is the transistor circuit near completion. At this point the apartment was also starting to become a little less messy.

Figure 20: Another shot taken from the side view.

Figure 21: Behold the final product. Shown is the "front of the guitar" with the fret board (right corner) and body of the guitar (center). The body of the guitar embeds the knob of the 12-position rotary switch and the 7-Segment LED to display the key-signature A-G#.

Figure 23: Ready to rock out. Well... if it were a real guitar anyway:-)

Figure 24: Shown is a video demonstration of the technical aspects for the project by Ryan.

Figure 26: Shown is a video demonstration of how the project is implemented on a real guitar.
