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…

David This week I worked ordered the PCBs for the TP sensor and TX/RX boards. Given that it is Carnival and we are waiting on parts, that is the extent of what is productive for my tasks. I have also begun to think about the TP sensor demo mounting. It Read more…

David This week I worked designed the PCBs for the TP sensor and TX/RX boards. First, the PCB for the TP Sensor had to accommodate the Arduino Pro Mini, as well as the socketed HX711 Load Cell Amplifier board, and the NRF24L01 RF Communication Board. Due to the 5V nature Read more…

This week I worked finalized the TP load sensor integration with the rotation sensor. The system uses an acrylic piece mounted inside the TP tube to trigger a contact switch mounted on the end of the TP axis. This triggers the start of a “wiping session” in the code, telling 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…

David Murray (Week of 3/4)
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…
