This Week:
- Found optimal distances for the wireless charger
- Created a half-row model of the sensing array on a breadboard to test
- Tested breadboard array with Android/Apple Phones and wireless earbuds
- Sensitivity was weak for Androids – Added non-inverting amplifiers
- Procured Opamps, Resistors, and Capacitors
- Updated PCB model to reflect Opamp additions
- Wrote sensor polling code and began device map code for the Arduino
Current Schedule:
Additions to circuit and supply chain problems still have our schedule somewhat behind. Still tons of slack in the schedule that we can use to catch up if we do not return to schedule by the end of the semester
Next Week:
- Assemble PCBs (if they arrive)
- Finish Arduino device map
