  16. SCINTILLATOR Budget Impact: $0.00 Actual Value: $500.00

  17. Budget, Schedule, & Technical Risks • Technical Risks • The scintillator isn't polished and coated properly. • Budget Risks • The scintillator material costs more than the budget allows for. • Schedule Risks • Ordering more material and preparing it would take weeks.

  18. PHOTO-DETECTOR S10362-33-025c Budget Impact: $0.00 Actual Value: $344.00

  19. Budget, Schedule, & Technical Risks • Technical Risks • The photo-detector isn't sensitive enough or the output pulse is too small. • Budget Risks • The photo-detector costs more than the budget allows for or requires more costly amplification. • Schedule Risks • If the photo-detector doesn't produce a large enough pulse, then a new method of photo-detection will require more time to develop.

  20. AMPLIFIER AD8000 Budget Impact: $0.00 Actual Cost: $1.83

  21. Budget, Schedule, & Technical Risks • Technical Risks • The amplifier cannot amplify the signal enough for the Arduino, or the circuit is too noisy. • Budget Risks • The amplifier requires a more sophisticated service that costs more than the budget allows. • Schedule Risks • Designing a new circuit will take extra time for design and manufacture.

  22. PULSE STRETCH

  23. Budget, Schedule, & Technical Risks • Technical Risks • The pulse stretcher cannot lengthen the pulse enough for the Arduino to properly sample. • Budget Risks • The pulse stretcher requires a more sophisticated circuit that is more costly. • Schedule Risks • Designing a new circuit will take extra time for design and manufacture.

  24. HIGH VOLTAGE EMCO-A01 Budget Impact: $59.99

  25. Budget, Schedule, & Technical Risks • Technical Risks • The power supply cannot be controlled properly for the photo-detector. • Budget Risks • A more precise power supply is more costly. • Schedule Risks • Finding or having to build a proper power supply will take extra time

  26. DON LUNDI • GPS • WIFI

  29. Flow Chart

  30. Budget, Schedule, & Technical Risks • Technical Risks • The GPS receiver provides times that are lagging that of the signal received by the GPS satellites • Budget Risks • Having to purchase dedicate timing GPS receiver • Schedule Risks • If the EM-406A does not allow for the timing resolution needed replacing the receiver will take time.

  31. WI-FI • Arduino WIFI Shield • Protocol: 802.11b/g • Clock Speed: 16MHz = 63ns • Operating Voltages: 3.3 • Ease of Interface: Minimal Programming Required • Budget Impact: $84.95

  44. Cole Gray Lead Mechanical Engineer • Structure of Cube

  45. Sub-Cube Structure The top compartment will be all Aluminum, but is shown clear to see inside the sub-cube.

  46. Sub-Cube Structure • The sub-cube will be 11.5” on a side. • It will have a top compartment and bottom compartment. • The top compartment will house the scintillator. • The bottom compartment will contain the electronics. • Once the size of the electronics are known, shelves will be designed in the bottom compartment to hold the electronics securely.

  47. Top Compartment

  48. Top Compartment • All six sides will be made out of 3/16” Aluminum • The sides will be bolted together using #2-56 bolts 5/8” in length. • The bottom side will have a small hole in the center, that allows the sensor lens to slightly fit through. • Angle Aluminum will be used to securely hold the scintillator and the ecomassmaterial in place.

  49. Bottom Compartment

  50. Bottom Compartment • The four walls, and the bottom side will be made out of 3/16” Plexiglass. • The sides will be bolted together using #2-56 bolts 5/8” in length. • This will allow light through, but will allow the consumer to see the “brains” of the cube, and will be more appealing. • A rubber gasket will be added to all edges to improve water resistance
