This week I had presented the proposal and rehearsed the speech in order to deliver in an engaging manner and also read through the application notes of several microcontrollers to see what will be the base microcontroller to use for our main pcb. In addition, Zhejia and I researched on inductive vs resonant charging and decided we best make an inductive charging station as that appears to have a more straightforward design. I found a test schematic for Zhejia to then test out to make a proof of concept.

We solidified our plan that the microcontroller be a USB-C that will plug into the computer with ease and that we can just have it run on BLE instead of having the conversion from BLE to Bluetooth, this can reduce latency and switching between too many protocols.

The magnetic charging will require the PCB so it’s debatable on whether we can use that for the hardware component of capstone and or I could focus more on optimizing the space for the key PCBs, I’ll consult with the TAs and faculty on whether this is a good idea. Either way using the NRF52832 will be useful as it’s a small microchip with great specs, speedy and small.

Next week I’ll research harder into how PCB layout works, as that is probably the subject that is of most concern for the keys.

Originally was thinking stacking the key PCB with the SEEED and the magnetic receiver pcb would be enough but I’ll look more into how the connection would work.

This week I did not get as much progress in depth research into the PCB making, but next week shall be full send.

What did you personally accomplish this week on the project?

This week I solidified with my teammates of our project idea and ensuring our project requirements and use case are valid in order to continue. Continuing forward I started researching how Bluetooth Low Energy works in regard to client and server connections. I completed my status report for the week, the team status report, and slides for the proposal

Is your progress on schedule or behind? If you are behind, what actions will be
taken to catch up to the project schedule?

Progress is a bit behind in terms of researching BLE  I plan to do more research on how BLE works and also figure out what other footprints would be necessary for the PCB and if we need one. In terms of assignments, I am doing my part to be on track with assignments.

What deliverables do you hope to complete in the next week?

Completing a picture of logistics is crucial and having a draft of footprints and other parts needed in order to also determine how large our keys will end up being.
