156B Week 5

Past week accomplishments:

• Tested out mold prototypes and determined their flaws (Udai)

• Finalized FSR circuit to produce accurate readings (Philip)

• Integrated circuit elements and looked into pressure sensors (Ryan)

• Set up and tested out Arduino scripts and entire system (Karie)

Sponsor Feedback:

• Passed along some medical gauze

• Has a physical barometer that we can use to measure balloon pressure

• Wants us to start looking for future vendors that he can take this product afterwards

Instructor Feedback from last week:

• Tolerance the 3D holes better since they come out smaller

• Look into other types of mold releases

Current Concerns:

• Hope the FSR zero data will be consistent

• Finalize balloon design and test out the new model. Determine the risk of leaks

Next Steps:

• Start on the PCB design (Philip/Ryan)

• CAD up and start 3D printed a housing container (Ryan)

• Get the pressure of the current prototype and write automatic controls (Karie)

• Cure and test out the current mold design (Udai)
