Phase II Review

MSD IIP14347

•Size is too big and not comparable with original testing

•Hinge is not possible with rapid prototyping, metal hinge would need to be added

•Moment is generated along wrong axis, attachment must open from impact force

•Four parts with a lateral break are required to install circuit boards

•Exposed wires between both boards

Mechanical Issues

Mechanical Solutions• Tether (Fishing Line, Kevlar Thread, Key Ring)

▫Eliminates the need for hinge▫Smaller moment required to open; Foam tape

for testing to hold together• 1 PCB?

▫No exposed wires▫Reduces risk of damage to PCB by separating

the PCB from impact site▫Barbed hook will now have a sturdier design▫Printed parts would reduce down to three

instead of four

Electrical Accomplishments

•Able to successfully log into Raspberry Pi•Using Matlab to send digital signal•LCD Screen assembled

▫Able to display inputted latitude/longitude•Design with minimal PCB?

▫GPS antennas need to be surface-mount

Transceiver / Raspberry Pi Update

Team Assessment•Still several key items to be addressed•PCB design and GPS receiver ->

Transceiver highest priorities•Raspberry Pi working after this past week•Need to seek guidance from Linx

Next Steps

•Purchase more parts•Contact Linx, sort out issues•Update MSD I documentation•GPS receiver interfacing with transceiver•Hold tight for smaller transceivers•Final PCB decisions
