Well, if I had the spare money to buy one I probably would, but I'm also just interested in finally doing something from start to finish with more intimate knowledge of what I'm doing. Opening one up to see what's inside seems like it would take away from that.
Thanks again for all the help! Sounds like I just need to find a DC power supply for determining the coil properties then go for it and troubleshoot as I go. You guys have given me a lot to think about if I encounter problems with the current design or if I want a more refined design in future.
Since they are going to be about an inch away from each other, I don't think the pickup coil will interfere with the drive coil, unless there is some effect from the harmonics of the string causing them to be out of phase.
If direct coupling happens with the guitar pickups, I think I'll just...
Thank you for the help so far. If I am eventually able to construct a driver coil that can deflect the string with a reasonable amount of power, should my input coil be the same as the driver coil?
Thinking about it, if either coil is right above the pickups this might be an issue. All I know is that the Ebow doesn't seem to have this problem and that keeps giving me hope.
You gave me an idea with the DC pulse testing. If I take a coil with known values for N, length, R, and μ then hook...
Right, the purpose of this project is to create a gadget that will essentially "pluck" the guitar string through feedback. Obviously, this will have a very different effect from plucking because the amplitude of the string's vibrations will swell. I'm not worried about the feedback getting out...
I need a little help with a project I'm working on. Here's the gist of it; I am taking two coils, hooking one into the input of an amplifier circuit and the other to the output. Both coils will be over an electric guitar string. The guitar string when vibrated will have a changing induction...
What about the physics class gave you the most trouble? Would you say it was mostly the math involved, or the concepts? Either way, you'd be able to work on what is causing the trouble for you. Solving physics problems just takes practice. In my opinion, if you haven't taken a physics class in...
Just to start off, I'm kind of in a hurry while writing this, but hopefully it will all make sense and if not I should be able to clear up any misunderstandings a little later.
I'm a sophomore majoring in applied physics. I haven't been able to start the general physics (calculus based) until...
