The most significant risk is there not being enough acrylic due to a measurement issue as well as our converter for the strain gauge possibly not being enough/not compatible with it. We plan to do the outer design with wood or another material that is easier to find/procure instead of acrylic if it comes to being not enough. For the strain gauge, we will try to use the 8bit with the alternative and see if there is any difference, worst case we will ensure our motion sensor works well and use the strain gauge as a less accurate but still efficient secondary drop sensor.
The stepper motor is no longer being used due to compatibility issues with the Nano that was not discovered till later, it is now replaced with an extra 20kg servo. We did have an extra cost for the new converter for our strain gauge, but that is more worth it should there be a secondary check to our motion sensor. For now, only one ESP32 is being used for simplicity, but this will be changed once we integrate the software-hardware interfacing after the demo.
Schedule is same as last week.
