 +The enclosing box was built out of scrap wood. The components were mounted to the base, and the motor was hooked up to the circuit board. A switch was added to turn the power on and off. Hyperterminal was utilized to communicate with the micro controller. Sevceral tests were run to detrmine the spectrums, and the microcontroller was programmed to scan the spectrum while gathering data, and then rewind. A light enclosure was built to allow no ambient light into the system.

-We began mounting the optical components onto the base. The construction of a better slit is being tested. The programming part is being improved. The physical diode translation unit has been tested with the existing circuit: the result is that there is enough torque. Also, the diode has been mounted to the fly nut. Wires have been chosen to be long enough to not interfere with the motion. +We began mounting the optical components onto the base. The construction of a better slit is being tested. A small change to the program was made: the stepping rate of the motor was increased. The physical diode translation unit has been tested with the existing circuit: the result is that there is enough torque. Also, the diode has been mounted to the fly nut. Wires have been chosen to be long enough to not interfere with the motion. During testing it was demonstrated that the diode does translate down the bolt as the motor rotates. An enclosure is still required to prevent ambient light from saturating the photodiode.
