6. CS-EE 480 Fall 2005 6November, 2005 University of Portland School of Engineering Scorecard Last months plans: Finish designing and begin testing CMOS chip Meet with industry representatives and advisors Research parts to be used Complete: Finished initial design of CMOS chip in B2Logic (may add additional features) Met with industry reps and advisors Incomplete: Research of parts to be used (still in process)

7. CS-EE 480 Fall 2005 7November, 2005 University of Portland School of Engineering Additional Accomplishments Initial testing of B2Logic circuit works well Functional specification 1.0 completed and approved Found out that most expensive parts (DC motor and controller) may be able to be borrowed from UP

8. CS-EE 480 Fall 2005 8November, 2005 University of Portland School of Engineering Plans for Next Month Completely finish designing and begin final testing of simulated CMOS chip Turn in completed B2Logic (.edf) file to Dr. Osterberg to create.tpf file (11/22/06) Find/order parts

10. CS-EE 480 Fall 2005 10November, 2005 University of Portland School of Engineering Concerns/Issues No errors in B2Logic (.edf) design Finding/scavenging cheap DC motor and controller Compatibility of CMOS chip with optical sensor output Creating a “reference” distance for the counter, finding/making the correct wheel

11. CS-EE 480 Fall 2005 11November, 2005 University of Portland School of Engineering Conclusions Project Beaver Marsh is on schedule and will act as an odometer B2Logic circuit is coming along well Biggest concern is with parts
