This week I continued to work on the schematic for our custom PCB. Due to some design changes I had to switch certain components out and ensure that the ones we maintained were able to work with the rest of our components. This required a lot of overhauling of current work (updating BOM and components list) which occupied the bulk of my work this week. Some of the new components included the external keyboard instead of building one on the PCB so I explored some tradeoffs in that area and looked at previous capstone projects that successfully used both options. The current decision is to work with a keyboard through the ribbon cable as opposed to the USB port which was the original reason why we ruled out the external keyboard option. I also updated our Gantt chart and planning schedule based on our new design so the work was evenly spaced out and accurate to the scope of our project.
Finally, I also worked on our Design Presentation slides and started preparing for the Design presentation in the upcoming week as I’ll be presenting for our group.
This week I plan to source further feedback on my schematic (have previously discussed with a peer and faculty on certain design choices) as well as presenting the Design Presentation. This should keep us on our updated schedule as the removal of the Arduino means I’ll be freed up to work on the external keyboard hardware and test it thoroughly.
