tos Posted July 8, 2006 Report Share Posted July 8, 2006 I just roughly tested output of electro-motor from an old SONY Discman.When i spin it with my hand i can get +/- 0.6V. How about using something like this for scratch input [instead of optical mouse reading, encoder input] would anybodey be kind enough to help me develop a circuit between a motor and AIN. As much as I guess it could be done using some sort of comparator circuit and a x15-x20 amplifier. But what it would actually need, I don't hane an idea.conception:-when motor is not moving, the ain is fed with 2.5V (at least I have such need)-when motor starts moving, the voltage on it's output is amplified by 15-20 times (min/max 0V/5V)-since it is a simple discman application, it can simply be used with some cd that is broken.Will someone help me with this? I will assemble a circuit (as long as it is not too expensive or complicated) and test/document this application(if it get's working) once I have circuit on paper that has a chance of doing something.
