You will need:
- gear box kit
- 2 mm wire
- 0.2 mm wire
- 9 V battery
- used 1.5 V battery or adjustable power supply (not over used because you still need some power)
- 9 V DPDT relay (12 V relay can work with 9 V if it is new)
- two 2N2222 or BC327 transistors
- two 2N2907A or BC337 transistors (you can use a TIP41C power transistor to drive the relay instead of 2N2907A/BC337)
- two 2.2 kohm resistors
- four 22 kohm resistors
- one 220 kohm resistor
- one1N4002 diode
- soldering iron
- wires (many colours)
Step 1: Assemble to Gearbox
Step 2: Creat the Stand for the Bird
Step 3: Create the Body of the Bird
After you make the bird you attach it to the gears from 0.2 mm wire.
Step 4: Attach the Bird to the Stand
Step 5: Attach Electronic Terminals
Then attach the 2 mm wire to complete to front terminal.
Step 6: Make the Circuit
The "bird front" is the front terminal.
The "bird stand" is the back terminal connection.
Step 7: Attach the Relay
Step 8: Connect Power
Keep in mind that the voltage must be 1 V when connected to motor. When you connect the battery to voltmeter without the motor you will see a higher voltage because of internal resistance of the battery.
This is how the bird should look like in video:
