Team status report 4/10
This week was focused around getting the demo ready for Wednesday. The shell was printed and tested with the buttons and LCD components. While the shell was designed around the PCB, it also fits an arduino uno which will be used for the purposes of the demo on Wednesday. The app is ready to integrate data from the scale but needs to incorporate the BTE connectivity. The appropriate hardware for that was ordered so that that work can begin. Lastly, the load cell interface is being worked on with an arduino uno substitute as well. While this doesn’t involve the MCU we originally designed around, using an arduino for all the components will make the seperate sub-system integration more seamless.

This week the team made progress in researching a new load cell and using it with our amplifier. We also made progress with the firmware and ordered all the parts that won’t be assembled on the PCBs when they arrive.
Team Status Report for 3/20
This week the team focused on the design review report making sure to incorporate any details that would clarify the questions asked after our presentation. Next week we hope to make headway on the firmware and will continue to push forward on the firebase/app development.
Team Status Report for 3/13
This week the team did the design presentation. We put the PCB Cad into the shell design as well as go through the integration of the components into the shell. We set up upload and download with cloud storage and made progress on the dashboard of the app. This week we have to work on finishing up the physical design report.
Team Status Report for 3/6
This week we created a a shell for the scale keeping in mind the physical spacing of the PCB in the overall design. We added the PCB model to the design and were able to flesh out a rough housing for the scale. We discussed different materials that we would be able to use. . We started working on the firmware for the PCB and will continue working throughout the next week. We got the app started and began progress with storage. We worked on more schedule and task breakdowns for the design review.
Team Status Report for 2/27
This week, the team worked on finishing up the schematic and board of the PCB. Several different components were added including Load cell, connectors, bluetooth trace + driver. In addition, research into using flutter for our specific application purposes was done. At the end of the week, the team was able to confirm the design of the PCB and sent it for checking before manufacturing. Flutter documentation for the app was looked into, as well.
Team Status Report for 2/20
This week we worked on the design proposal, created a list of requirements, and started on PCB design. We did research on the best and most cost effective components for our design and created a Bill of Materials. The materials included a load cell, load cell amplifier, load cell connector and terminal block, voltage supervisor, JTAG, STM32, and others. We did some research on various cross platform app frameworks and decided on Flutter. We also created a Gantt chart and divided tasks between the three of us. In terms of PCB design: .
