This week was the in-lab demo before the final presentation. The demo went well, all of the functionality we designed in the revised project was working properly. The remainder of the week has been spent working on the final presentation and poster, as well as preparing for the final presentation Read more…

This week I assembled the PCBs for the TX/RX boards and the TP Sensor. There was an issue with the TP Sensor where the pinout of the 3.3V regulator was not correct in the footprint of the design, so I ended up needing to use jumper wires to connect the Read more…

This week I worked on finalizing the TP load sensor, began designing the TP rotation sensor, door latch sensor, and working out plans for the overall TP sensor PCB. The sensors are progressing well, and I should have a finalized design shortly. Looking into the PCB costs, the parts needed Read more…

This week I worked on ordering parts for the final prototype of the load sensor, as well as critical RFID components (tags, reader, and raspberry pi control module). Due to Spring Break, there is a bit of a reduced timescale this week, I, as well as my groupmates, will be unavailable starting either Read more…

This week I worked on the design review report, as well as prototyping the TP load sensor, and prototyping the initial functions of the reader. The group all worked together on the design review report, which took up a fair amount of time. Now that the load sensor parts had arrived, I Read more…

This week I worked on the design review slides, as well as further specifying components, ordering, and creating backup plans. The first parts order was placed earlier this week, consisting of the microcontroller, load cell amplifier, and load cells. This will allow us to prototype the load sensor early next week once Read more…
