= Project: RC Boat Replacement Guts
Removed RC boat's control system from the transmiter and receiver and replaced them with a pair of Adafruit Feathers with built-in 900 MHz LoRa radios. Also replaced the old 9v battery and AA batteries with rechargable LiPo batteries and dedicated chargers for the transmiter and receiver.
== Steps Cut out old boat's receiver's guts. Install Feather in boat and connect H-bridge chip to propeller and rudder motors. Stuff LiPo battery, charger, and extra USB-micro female port to the boat. Remove old transmiter's guts. Install feather into transmitter's body. Install new potentiometers and power switch. Install LiPo battery, charging circuit, and USB-micro female port. Using Arduino's IDE push firmware to both Feathers. Find water to play in. Play in the water.
