Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   After all the painting and finishing off the One String Electric Guitar has been finished. I re-installed the pickup and wired it directly into the headphones amplifier  as this enabled me to create an untethered system that I could then plug directly into the main music amplifier that I have. It wo ...
Electromagnetism Enter Your Electronics & Design Project for a chance to win a $100 Shopping Cart! Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   Once the final guitar body had been shaped it was time to paint it. I decided to follow a painting strategy of undercoat then top coat of spray paint. The undercoat was just a wood primer and undercoat combined, which I sanded down after the first coat and then undercoated it again and sanded it again to ...
Having created the prototype one string electric guitar body and pickup I wanted to be able to hear the sounds it makes. I don't have a guitar amplifier so I decided to use an ordinary music amplifier instead but this needs a pre-amp to make it work. There didn't seem to be any such thing as a guitar pre-amplifier, all I could find were expensive foot pedal pre-amplifiers which were not for me. Then I stumbled across electric guitar headphone amplifiers, which do exactly what I wanted, so I purc ...
As the prototype body for the one string electric guitar has been completed the next step is to make the pickup coil. I have previously made a 3D printed bobbin to wind the coil on so all I need now is to select the wire to be used and wind it. I have selected the thinnest wire I had, which is 'pretty thin' (that's a technical term for non-mechanical engineers like me) which I think is 32 SWG or 38 SWG. It is so thin I can barely see it, even with my glasses on. It is enamelled so that the coils ...
I thought I would start the building of the guitar body with the pickup itself. As I have a magnet which I think is suitable I decided to 3D print a bobbin that fitted it to hold the winding coil. The magnet is 8 mm in diameter and 15 mm in length so I looked at making a bobbin with these dimensions. I also looked at what wood I might have available as that might have an impact. I found some pine plank that is 22 mm thick and 71 mm wide and about 750 mm long. I don't know how long a guitar shoul ...
I saw the Project14 monthly topic of Electromagnetism and thought about it for a bit and couldn't think of anything that I could do - there didn't seem anyway of involving mobile robots in this, so I had decided not to participate. Some time later it occurred to me that maybe I could make some sort of electric guitar. I am no musician but I can just about plink out Doh-a-deer, a female deer on the piano with one finger. I can just about do the same on a guitar so I thought maybe I could make a o ...
