Introduction: Remote Controlled Paper Airplane-TV Remote
Create a remote controlled paper airplane controlled by your average tv remote. Super fun and cheap to make!
For step 1, you must obtain all the materials: a small li-poly battery (3.7 volt), a piece of PCB, electric micro motor with propeller, 100 uF capacitor, 100 ohm resistor, 220 ohm resistor, red LED, BC557 transistor, IR receiver, straws, velcro, a plastic piece.
For step 2, you are going to want to make a good paper airplane. A good paper airplane to make is a glider.
For step three you are going to want to find the center of gravity. To fins the center of gravity, you are going to want to hang the paper airplane by a string and keep moving the string until the plane completely levels out.
For step 4, you want to start to build the circuits.
For step 5 you want to start soldering everything together by putting the piece against the parts.
Step 6: Connect
For step 6, you want to connect the circuits to the motor. You can do this by connecting the limply battery to the motor.
Step 7: Testing
For step 7, test to see if all components are working correctly. Press any button on the remote control, and the motor should start spinning. This should give off a slight breeze from the propellor.
How it works?
The IR reciever accepts the signals from the remote control. The capacitor filters the frequency of the 38kHz signal so your LED won't blink. This is very important. The BC557 transistor amplifies the current of the output then drives the motor and the LED.
Step 8: Connect to Paper Airplane
Place the control unit where the center of gravity on the plane is located. Cut a piece of the plane for the propellor to be.
Step 9: Let It Fly!
Hold the plane by the control center. Throw the plane lightly in the air. Let is fly for a couple of seconds, then press any button on the remote control to start the propellor.
