Accomplishments
Whole Team – Long Ethics Assignment!
Anirud
– Enhanced PCB design, incorporating an op-amp and feedback resistors, crucial for improved sensor accuracy. Shifted all components to the top layer to eliminate interference with the wireless charger.
Luca
– Collaborated on revising the sensor array circuit diagram, integrating Op-Amps for better signal detection.
– Managed unexpected hardware issues: resolved a machining flaw in linear slides and dealt with a sudden laptop breakdown.
Callum
– Developed a half-row prototype of the sensing array, focusing on fine-tuning device sensitivity.
– Implemented non-inverting amplifiers to the array to clearly distinguish Android device signals from background noise.
Risk Management
– Supply Chain Delays: Actively monitoring supplier communications and exploring alternate component sources to minimize impact.
– Hardware Issues (Luca’s laptop, linear slide defect): Quickly addressing problems as they arise with practical solutions.
Design Modifications
– Op-Amps in Sensor Array: Added to increase the fidelity of device detection, especially for Android devices.
– PCB Layout Redesign: All components moved to the top layer to facilitate seamless integration with the wireless charging system.
Revised Schedule
In response to the recent challenges, we’ve adjusted our timeline to prioritize completing CAD work and assembling the full sensor array.
Project Highlights
– PCB Design: Anirud’s work on the PCB layout shows thoughtful problem-solving in response to integration challenges. https://drive.google.com/drive/folders/1UKzUN_nZ_kdPh8fONkxHx-t0Cf490zzb?usp=sharing
