    ...I just built myself a theremin based partly on this [oldtemecula.com]. It transmits a pair of RF signals at around 1MHz. As you move your hand around it varies the inductance of the coils so that the coils transmit at slightly different frequencies. As a result you get a signal at the average of the two frequencies modulated by the beat frequency. Tune an AM receiver to the average frequency and you get to listen to just the beats. It took a couple of hours to build. (The project I linked to above has an AM receiver built into the circuit but I didn't bother with that as I already had a spare radio.)

    Yet again we see a slashdot article that mentions something neat that people did with a PC with a general purpose operating system. Does the operating system matter or is the choice of OS even interesting? Probably not more than and possibly much less than the programming language that the thing was written in.. but does that get mentioned?

    Face it, folks. Linux is a general purpose operating system on which you can do all of the expected things that one can do with such. We are WELL past the time where you can do basic things, like program and use webcams, on Linux, and nobody reading slashdot really needs to be fluffed further in this respect.

    As far as this story goes, unless the inventors did something that could more or less only have been done on linux, then the linux aspect of this story is irrelevant.

    • No, I disagree. Perhaps maybe not the Slashdot crowd, but in general, the non Linux users still see Linux as a server OS. I once showed someone a video on Linux and the reaction was "Huh, that's weird. I have a hard time imagining a video running on Linux". He said this as he was _watching_ the video and as if he couldn't believe his own eyes (no it wasn't pr0n).

    As a musician and computer geek, I'm really fascinated by how they do this. There are so many nuances to guitar playing that it will be intriguing to see how they can pull this off.

    For example, does it analyze the angle/arc of the left hand to determine which strings are being stuck? That would suck to slightly arc your hand and suddenly you're playing the wrong string.

    How does it determine where your left hand is in relation to the position of the neck? There are various neck sizes, after all.

    The article implies that this is meant to simulate an electric guitar. With acoustic, you can strum on just about any position on the string and it will sound the same. With electric, the sound varies on the position due to the different pickups, each with its own tonal qualities, but each pickup is only an inch or so apart. Can this differentiate such minute details?

    Don't get me wrong. I'm not looking at this as an "all or nothing" deal like a lot of people do on Slashdot. Oh, well, it can't do everything so it's teh suck! This is a very interesting start. I'm pondering more for what its potential could be more than what it can do right now. The whole cliché of taking baby steps first comes to mind.

    Personally, I'd rather play the real thing. But at least this method could get people interested in guitar playing if they are too intimidated to buy a real one. And this won't result in painful calluses at the finger tips. :)
    • Heh I asked the same question. See the answer here [slashdot.org].
      • Realistically, they *could* do it. Set a position for the strumming hand, press a pedal to set the position, set a position with the other hand for farthest fret, press a pedal to set the position, set a position for the innermost fret, press a pedal to set the position. Now the system has a way of determining the distance from the strumming hand and could simulate chords based on how far away the chord hand is from the strumming hand. For example, the farthest is C Maj, the next step in is D Maj, etc.
