This Instructable combines Arduino programming, some simple electronics, carving with hand and power tools, mechanical control and a bit of woodwork. Apart from the Arduino and a few components it is mostly made from reclaimed materials.
I am rather pleased with it.
What's in this instructable
I have included the main circuit and controlling Arduino programme (the sketch), and issues that arose, but I have also tried as much detail of the other (physical) making processes involved, so hopefully some of that stuff may be useful if you are building something in a similar way.
This project includes:
- the Arduino details, such as type of board, file type, the full Arduino sketch that controls the head, etc., and acknowledgement of included code such as the servo.h library.
- how the eyeballs and sockets were developed using prototypes, their construction from roll-on deodorants and the mechanism that controls them
- how the wooden head was developed using crude rapid-prototyping in polystyrene laminate sheets and how they were then used as templates to transfer the 3-d design to MDF boards and create the final casing
- the carving methods using hand and domestic power tools
- some discussion of the use of domestic materials such as garden wire and recycled objects to save on costs
- testing various LEDs for eyeball lamps and overcoming the power limitations of Arduino outputs using a simple transistor amplifier circuit
- more detailed discussion of the Arduino code and how it works to manipulate and translate analog inputs to the positioning servos and eyeball lamps
- details of the construction of the wooden base unit and controls, some simple boxmaking and woodturning without a lathe
- how a plastic power supply was converted into a wooden supply
- handy tips that might be worth considering in similar projects
