More on the $1.29 diversity controller for FPV RC planes and multirotors...
What is PWM and how does a capacitor turn a digital signal into an analog one?
In this video I look at "integration", a fancy term for simply using a capacitor to smooth out a noisy or digital signal.
The first example is the integration created by adding extra capacitors to the $1.29 diversity controller, the second example talks about turning a PWM RSSI signal into an analog one.
Let me know if you want more of this type of techy videos while I'm waiting for my flight exemption to come through.
