  1. Project RNG: Radiation-BasedRandom Number Generator • Team Oregon Chub • Ashley Donahoo • Colton Hamm • Alex Brotherston • Matt Johnson • Advisor: • Dr. VanDeGrift, Dr. Hoffbeck, • Dr. Osterberg • Industry Representative: • Mr. John Haner • Bonneville Power Administration University of Portland School of Engineering

  2. Introduction • Our project generates random numbers from radioactivity • Building a radiation sensor, designing a MOSIS chip and using 7-segment displays University of Portland School of Engineering

  3. Scorecard • Received all ordered parts for analog circuitry. • Successfully used .abl file to burn-in the CPLD macromodel. University of Portland School of Engineering

  4. Additional Accomplishments • Completed LabVIEW tutorial • Received BCD-to-7-segment decoders and 7-segment displays from Craig Henry. University of Portland School of Engineering

  5. Plans • Completely test and verify CPLD functionality. • Completely test and verify 7-segment display and decoder functionality. • Meet with Allen about case design. University of Portland School of Engineering

  6. Milestones University of Portland School of Engineering

  7. Concerns/Issues • Inexperience with CPLD’s, 555 timers, 7-segment displays and decoders could lead to delays • Concerned about how much time LabVIEW will take to set up • Various interfacing issues University of Portland School of Engineering

  8. Conclusions • CPLD has been created and is ready for testing before implementation into analog circuitry. • We are now focused on the analog portion and having it interface with the Geiger tube. University of Portland School of Engineering

  9. Questions? University of Portland School of Engineering
