Building the Guitar
Setting it up in the dark
The Finished Ultimate Guitar
Complete menu systems that allows the user to select a desired scale and key (ex. Penatonic Blues in G) and then display it on the Fretboard. A metronome can also be used to help keep tempo.
Guitar with fretboard in the key of E Major.

None the less, the idea is still kind of interesting. Take a look at the models below that I created with Autodesk Inventor.
The Lightning Photography device worked by telling a camera to take a picture as soon as it sensed an increase in the amount of light in a certain field of view. To sense the light, 4 CdS photocells were used. IR sensors may have been a slightly faster approach, but since the camera takes pictures in the visible spectrum I wanted the sensors to do the same. In other words, there are different "thumbprints" that lightning produces depending on the time of day, the clouds, etc. and I wanted the device to only get triggered when the light it was receiving was of the same type that the camera could see. I then used an Op-Amp as a comparator to make a cut-off point. The user could then select the sensitivity / cut-off point with a series of potentiometers (used similarly to the way a voltage bias would be implemented in an AC circuit). An LED was also implemented for quick setup during a thunderstorm. When the signal from the CdS Photocells was greater than that of the comparators reference voltage, a relay was triggered. This closed a circuit to the camera that took the picture.
A prototype was built, and after many hours of soldering / trying / re-soldering, the device was successful. I used it during a few thunderstorms and the results were incredible!
