WORK ACCOMPLISHED:
This week I focused on finding and comparing quantitative measurements for the hardware materials of our device in order to justify our use case requirements in our design presentation. I focused on exploring current/power draw, baud rates, and pinouts to solidify how the wristband mechanism will receive information from the Raspberry Pi wirelessly, and how the wristband will be held together for the user. Also, I spent time building our design presentation.
I spent time researching different specifications for our batteries, sensors, and vibration motors. I started with current draw to make sure our batteries could sufficiently power our circuits for a decent amount of time. Next I fleshed out the pinouts for our components to refresh myself on creating circuits with a breadboard and to know if we had enough space to build our system on a mini breadboard . Additionally, we need to know if he had enough pins on our raspberry pi. Lastly I looked at baud rates for bluetooth module (HC-05) and average transmission times for our other components and they seem to be adequate to meet our latency goals. Between last week and now we decided to make this device only for bicycles that way we can attach our device underneath the bike seat so the rider isn’t blocking the sensors,
PROGRESS:
I’m currently on schedule with my tasks. We ordered parts and hope to see somethings arriving next week.
NEXT WEEK’S DELIVERABLES:
Next week, we hope to make any adjustments based on our design presentation feedback. Additionally, we hope to start tinkering with parts that may come in.
