Waving the Flag with Raspberry PI.

Bill of Materials
* Raspberry Pi
* Adafruit PWM driver PCA9685
* Power Supply
* 9V to 5V and 3.3V voltage regulator
* Micro 9g servo motor
* Packaging tape
* A Flag
* Wires
* A radioshack breadboard
* Software written in python Flag Waiver on github

Result:

My first soldering job on a PCB:

And second one on the voltage regulator:

You can’t beat the packaging tape:

RPi + breadboard (transistors and lamps are part of gpio project):
