in the arduino cookbook and fritzing, the basic example of a servo motor seems to have a third cable which receives the PWM signal from arduino. the motor that i have only has positive and minus leads. i was able to get power to it and make it spin, but not sure how to control it?
looking into making something similar to these "virtual turntable" surfaces that have been cropping up in the past few years. a motor spins a lazy-susan around, but if you touch it, it will stop the motor and send a signal back to the computer to stop playing the music (or find a new spot in the song).
here is one by numark that gets the concept across:
well you sir are a wealth of knowledge! yes i am definitely thinking about psychedelic rigs because i know they were low-tech and low-budget. lots of great ideas in your post that i really have to go through and digest. any added photos would be of great help to see exactly what you mean.
i'm looking to aquire some tools that will help build a nice, small, flexible kit for doing visuals in smaller venues. i am not tied to using projectors because they are large and expensive. i am more looking to make use of things that reflect, or create shadows. sorry this is vague but i dont really know where to begin.
one idea i had was putting some paper birds on a string and having a motor move the string. a light source would cast a shadow of the birds on to the wall, and they're moving with the music. stuff like this.
i might going the route of making little felt modules with the ports on them. nothing would be sewed down but i know that the tin can be used this way. would love to know any more ideas from people doing something similar!
thank you. yes i was pointed in this direction of using tin wire and it looks like a great option. i am going to add connectivity using little pin headers and sockets to make the paths a little more modular.
the only problem with tin wire i can see so far is that it can get tangled easily, and bunches up in spots (making mini hooks).
