The team has been hard at work after prototype inspection day 2. In terms of accomplishments, we have obtained initial capacitance test data with higher resolution than last semester, thanks to the new electronics and gantry. We have also found the optimum pressure for the capacitance sensor with the screw top in the casing; however, we still need to quantify this value. In addition, we have completed the preliminary inductive sensor code.
After collecting the spring data by manually moving the device on the gantry, we were able to solve the issue with the stepper motor for the gantry. With the issue fixed, the gantry was able to automatically translate around the scanning area.
Moving forward, we have several plans for the upcoming week. We aim to quantify the pressure and speed values for sensing and add filtering hardware and firmware for clearer signals. We will also troubleshoot the inductive sensor function and gather data to refine our results. Lastly, we will continue working on the 3D models for the final prototype casing, which will be a handheld device.
