This plotter was built using parts from cd disc drives. The parts that actually control the motion are the steppers in the cd drives. The steppers are normally used to move a laser diode back and forth over the disc to read it. For this project, a separate disc drive was attached perpendicular to the…
Sound triangulation is a method of determining where a sound originated from. Triangulation can give the location of a sound source in 2-d space. A sound wave travels out from its point of origin as a sphere. Trilateration is another method a locating the source of a sound. It is modeled around the fact that…

This is what a strip encoder looks like: They are used to add position feedback to things that move in a linear way. For example, printers and scanners. Some printers use DC motors with strip encoders as opposed to stepper motors. The reason for this likely because DC motors are cheaper than steppers.
