Camera crane control

In my first English post I want to present you a control circuit I made for a camera crane. At present this circuit drives 2 stepper motors, has USB interface for bootloader and communicates with a radio module - making the control wireless.

The circuit in the above can be controlled by the remote controller. Both of them are based on PIC18F4450 microcontroller. Remote control is allowed by the radio modules - RFM23B. The power supply is a 12V battery. Two motion is realized: pitch and yaw.
The remote controller is a joystick. The transmitter circuit is built in it's body.

The red LED indicates the battery state, the green lights, when there is a received signal.

Soon we will make a video about the operation, then you can see what kind of footage can be made with the help of a camera crane.
