MATT GIBSON • SENSOR (SCINTILLATOR + PHOTO-DETECTOR) • AMPLIFIER • PULSE STRETCHING • HIGH VOLTAGE
SCINTILLATOR Budget Impact: $0.00 Actual Value: $500.00
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.
PHOTO-DETECTOR S10362-33-025c Budget Impact: $0.00 Actual Value: $344.00
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.
AMPLIFIER AD8000 Budget Impact: $0.00 Actual Cost: $1.83
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.
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.
HIGH VOLTAGE EMCO-A01 Budget Impact: $59.99
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
DON LUNDI • GPS • WIFI
New Approach EM-406A Receiver Trimble Resolution T GPS Receiver
GPS Receiver Module Arduino GPS Shield • LED indicator • Built-in patch antenna • Hot start 1 sec., average • Cold start 42 sec., average • 4.5V-6.5V DC input • 44mA • 1us synchronized to GPS time • Budget Impact: $79.95
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.

Cole Gray Lead Mechanical Engineer • Structure of Cube
Sub-Cube Structure The top compartment will be all Aluminum, but is shown clear to see inside the sub-cube.
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.
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.
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
