Podcast Notes Trey German is back to give an update on completing the epic Icarus Trophy race. See Figure 1,2,3,4. Trey was previously on MEP EP#10: IoT's Cloudy Future. The Icarus Trophy race is a 1000 mile, unsupported, cross-country paramotor race that starts in Montana and finishes in Nevada. Trey is working on a Bluetooth connected device that fits in the wing of the paramotor. Using this he can get more flight information and data about pilot control input. It connects up to his phone which runs a custom app. See Figure 5. Trey's paramotor motor causes RF interference that disrupts the Bluetooth connection. He is working on shielding the ignition system with should solve the problem. The Scariac is a water based resistor built by Grant Thompson a.k.a. "The King of Random". Grant needed a way to adjust the power to this homemade stick welding system but couldn't find an easy or inexpensive way to control the voltage. The idea is to use water as the medium of the resistor and by adjusting the distance
