The devil is in the details
After building the Raspberry PI extension board it’s time to do some useful things with it.

This post describes a very simple way to do this as well as how to store the measurement data local as well as in the cloud.

Here I describe a way to connect nearly every R/C transmitter to your PC using an Arduino UNO
board. Why? Because I bought a quadcopter and hat some hard landings and crashes so I started
training on the PC using a flight simulator controlled by my R/C transmitter.
