Hi,
This is my first post here. I am an artist and i do a lot of work with old formats, such cassette tape, VHS, video 8 etc. Recently i have started to have an interest in trying to further manipulate these formats and to experiment with the properties of the machinery itself. I was hoping someone may be able to shed some light on a problem i'm having.
I'm currently working on an interactive art installation and my goal is to alter a series of old walkman cassette players so that as people move around them, the speed of the motor changes, and in turn so does the pitch of the tape.
I know that when walkman batteries become weak, the motor, and in turn the tape gradually slows down. This is the effect i would like, but so far i've only been able to shut the motor down entirely.
Essentially i would like it so that the closer someone is to the walkman/sensor(s) the speed slows down, and when they move further away, it returns to normal.
I thought that using a motion sensitive potentiometer of some kind may work, but i'm really lost as to what components might be available for this, and whether this could create a slowing down effect, or whether it would just again, switch it off.
I did already try an LDR, but i wasn't able to cause any effect. I also fear, that since the installation is in a light space, an LDR won't be able to discern the very slight changes in light, particularly if people aren't very close. I feel motion detection, is the way forward, but i'm really lost there. I'm really not very experienced in electronics.
The walkman runs off two AA batteries.
It seems like a simple idea, but perhaps it's something that's actually quite complex to achieve. Either way, any light anyone could shed on this would be a real help to me.
Thank you!
