An excellent example of a voltage regulator in use is on the Arduino Uno board. The Arduino Uno has a 5-volt linear voltage regulator on its circuit board, allowing you to use its coaxial power connector to connect a power supply of 8 to 20 volts DC. The regulator reduces this to the ...
We have covered many cool drones here. None of them are powered wirelessly. Sam M’s idea looks brilliant though. It involves using wireless power to get a drone to fly. This particular quadrotor “consumes anywhere between 5-10W when it hovers with a shield on.” As the developer explains...
