Used heat shrink to prepare our vibration motor today. We're actuating nicely, but Laura is going to work on refining the algorithm so our actuation is even better on demo day. After letting our LiPo's dry out overnight, they are working as good as ever today! We decided we're going to wrap and seal them in balloons in the future to prevent them from ever getting wet again. That was way too close a call. We removed the right most power rail from our breadboard to give us more space to work with onboard. We're still waiting on our pressure sensor breakout, bluetooth chip, and waterproof switches. Hopefully all that stuff should come in tomorrow.
We need to 3d print at least one more shield before demo day this Friday. With only one working Makerbot in Detkin and a limited number working in the MEAM lab, there is naturally a very long queue to print this time of year. I snatched an SD card and intend to be the very first person in line when Parth comes in at 9:30 tomorrow. We're hoping to watertest again tomorrow, but we're not taking any chances this time. We're sacrificing all style points in favor of safety by wrapping the entire waterproof shield with 5-6 layers of saran wrap, ziploc bags, and duct tape. At this point, good water testing data is far more important to us than having a finished looking product.
Tonight, I need to re-CorrosionX all the tech for tomorrow. Tomorrow we're preparing our final demo shield with working LEDs and buttons, improving our actuation algorithm, presenting some data processing, collecting some more water data, preparing our presentation/video, and potentially interfacing the bluetooth if the chip has arrived. We have our work cut out for us, but with CorrosionX and elbow grease on our side, we're ready for the adrenaline to kick in as we cross the finish line.
