Make a remote controlled paper plane using your TV remote. via instructables

I love everything that flies. In my childhood I made a lot of paper airplanes, but they have a huge problem. After some minutes they fall down. So now I designed a small device that allows you to control the speed and the high of your airplane with a TV remote control. If you press any button on the remote the small motor starts to rotate the propeller and the plane accelerates. This thing can be suited to any paper plane, The weight of the full gadget is 9 gramms.

The power source is a small Li-Poly battery that can power up the circuit for about 10 minutes. It takes some time until you’ll learn to fly, but isn’t so hard. I made a lot of experiences with the circuit. This control unit can be used for others too, can drive LEDs, motors, relays or anything. Can be used for a home-automation project too.

Tools:
soldering iron
cutting tool
glue
crafting tools or rotary tools
Materials:
small Li-Poly battery
a piece of PCB
electric micro motor with propeller
100uF cpacitor
100 ohm resistor
220 ohm resistor
Red LED
BC557 transistor
IR reciever 38kHz
straws
valcro
and a plastic piece
These parts are very cheap so you can build this project from less than 6 bucks. You can replace resistors with another, but the value can’t be higher than 470 ohms. So let start building!
