I initially set out with the intention of building a speaker into an electric guitar in order to allow the user to have the guitar’s sound amplified to listenable levels without the use of a typical amplifier.  This problem is often solved using mini battery powered amps that can clip to the users belt.  I…

If you haven’t been following along, in my last update I had just gotten the amplifier circuitry working but with just noise coming out when the guitar is plugged in.  Through a bit of finagling I was able to get a clean signal coming through the power amplifier and to the speaker.  The speaker was…

I spent a fair amount of time working on this project over the break.  I currently have both amplifier circuits wired and functioning with an input from the waveform generator so we are off to a good start. Pre-Amplifier For the pre-amplifier I simply copied a popular design seen a lot in guitar forums originally…

I’ve made good progress this week like getting the pre-amplifier working which I will detail in a future post.  Today I want to discuss the constraints I’m placing on the project with the intention of making it as close as possible to what I want. Amplifier circuit must allow for overdrive While, it is not…

I have been working on playing my guitar more often this semester.  One thing that has helped with this is having my acoustic guitar on a stand in the living room of my house making it easy to pick up for a few minutes here every day as I walk through that room.  While I…

My goal for this semester is to try to expand my artistic side.  As I finish up my 5th year of engineering school I feel like my technical knowledge base is pretty solid and well rounded.  Despite this we have seen time and time again that design is more than just the technical side of…

Last year for Christmas a friend gave me an unloaded grenade as a gift.  Since getting a chance to play with it, the triggering system has fascinated me.  The system is very simple.  The pin holds the lever (or spoon) which holds back a spring loaded striker.  When the pin is pulled and the spoon…
