3. CS-EE 481 Spring 2007 3 University of Portland School of Engineering Introduction Project Beaver Marsh - digital odometer implemented with a CMOS chip. Tracks the distance that a rotating wheel has moved and displays it on 7-segment LEDs.

4. CS-EE 481 Spring 2007 4 University of Portland School of Engineering Planned Theoretical Layout MOSIS Chip & Circuit Housing LED Display Optical Sensor Electric Motor Wheel

5. CS-EE 481 Spring 2007 5 University of Portland School of Engineering MOSIS Chip Layout

6. CS-EE 481 Spring 2007 6 University of Portland School of Engineering Scorecard Last Months Plans: Complete circuit construction of CPLD to 7-segment decoders and 7-segment displays Continue circuit construction and part integration Continue work on demonstration platform Figure out what is wrong with signal between sensor and CPLD Complete: Circuit for 7-segment decoders and displays completed Construction of platform as well as part integration and circuit construction continued Incomplete: Still having problems with signal between sensor and CPLD CPLD does not count correctly
