When the can is closed with the cap, the Cyborg Heart is off. But, when you remove the cap, the switch is released closing the circuit and the Cyborg Heart start to light and move.
Step 1: Materials and Tips
1 heart shaped thing (I found a heart made of wood. It's Valentine's Time, so don't tell me you can't find a plastic or wood heart)
1 toy motor
1 Playstation joystick motor eccentric weight (or you can make your own eccentric weight using a plastic or metallic piece)
1 Big LED.
1 industrial switch (I dismantled it for the centre of the heart)
1 release switch
1 AAA 2 batteries holder
gears, scratch (for decorating)
red and black wire
screws and bolts
Dremel Rotary Tool
And don't forget the classic building rules (plus one):
1. If you don't have it, replace it!
2. Use protective equipment (dust mask and goggles)
3. Beware of drilled and soldered hot surfaces
4. Work in a good ventilated area.
5. Always have junk in stock.
Step 2: The Centre of the Heart
Step 3: The Circuit
Step 4: The LED
Step 5: The Motor
Connect the motor wires to the LED (remember: red wire = +, black wire = -)
Step 6: The Spring
Step 7: Decorating the Heart
Step 8: The Can
Make a hole in the back of the can, for passing the wires to the outer part.
Step 9: Final Touches
Glue the batteries box to the outside and connect all the wires according to the circuit diagram of the step 3.
Adjust the cap to the can and put a beautiful bow in the top. Put the batteries and... give your Cyborg Heart to somebody special!!!
