Mid-Phase Project Update
MSD II
P14347
Updated Documentation
• Updated Project Plan
• Updated BOM
Arrow Attachment Designs
Arrow Attachment Designs
Battery Selection
• Panasonic CR2032 (3V)
• Two in series for main
voltage supply, resistor
to bring down to
appropriate level
• 220mAhr
• Cheap, can be sold in
bulk
• Diameter: 20mm,
height: 3mm
Transceiver / Raspberry Pi Update
• Attempted to transmit analog signal using
transceivers with no success. Decided to test digital
signals instead because that relates to our
application.
• Came across a boot error ‘Kernel Panic’ and would
not allow Raspberry Pi to run due to issues with the
boot configuration file. This forced us to restore the
Pi back to it default settings
• Plan to use a code found online which will write the
message ‘Hello’ at the input, RxD, and read it at the
output, TxD.
Adafruit 1115 Blue + White 16 x 2 LCD
+ Keypad Kit ($29.95)
Team Assessment
• Electrically, raspberry pi analysis and debugging
causing problems
• Still questions to be answered: smaller
transceiver, antenna design, etc.
• Some parts have already arrived, others need to
be ordered ASAP
• Mechanically, not much to accomplish
• Arrow attachment PCB layout led to initial
designs
• Slightly behind schedule
Next Steps
• Rechargeable batteries for testing purposes
• Raspberry pi needs to be sorted out ASAP (order
another?)
• After raspberry pi situated, need to send signal
from GPS receiver to transceiver
• Test transceivers
• Refining mechanical arrow attachment design
• PCB discussions
