Candybox is a magical box for your sweets that helps you keep in shape. During periods of intense study it might be hard to resist the temptation of having a candy-indigestion. After several bellyache we thought it was better to entrust the control of our candy directly to a smart box.

CandyBox is apparently a simple wooden box, made up of laser-cut snap-fit parts of plywood. Yet an Arduino Leonardo board is hidden inside it and represents the brain of the Candybox. A TinkerKit shield is connected to the microcontroller to enable the Candybox to interface with the world outside. If we want a piece of candy, we should not do anything but run our hand in front of the box and voila, she will magically open. A light sensor makes it possible to perceive the shadow of the passage of the hand, causing the actuation of the servomotor which opens the box. We have just  ten seconds to take the piece of candy before the box closes. However it’s a bad idea to eat too many sweets when you are starving while studying. And here the Candybox comes to help us. After ten openings (and ten pieces of candy) the servomotor is switched off and the alarm LED starts blinking. We can make any acrobatic movement of the hand in front of the sensor, but it will be useless. Our inflexible Candybox will not open again for a little time.

Being the first project I’ve ever done in the field of digital fabrication, I wanted to create a simple but playful object, one that can be adapted to different occasions and even user mood.

With these ideas in mind, my object is not just a toy but an object with a practical use, since the top-front part can be opened. Such internal space is a real box that can be used to stock any items.

If the box is open: anyone can store any common objects. If the box is closed: the toy becomes a secret treasury box.

Requirements

  • A wooden plate.
  • An ABS reel, max 0.5 mm in diameter.
  • Two wooden sticks, long enough to become the axis of the car.
  • Glue.
  • Scissors.

Building the object

This project is a box with a simple internal mechanism, so be careful to test it before gluing the box! The car uses a principle very similar to what we find in windmills: the wheels are connected to a first internal sprocket, which is connected to a second vertical sprocket. Moving the wheels makes the mechanism spin, so kinetic energy is transmitted to the blades.
Once you laser-cut all the pieces, you can put together the mechanism. Start by gluing the center stage, where the whole mechanism is going to be placed. Then, you can prepare both sprockets, the four big car wheels and the blades. For both sprockets to touch each other, cut little pieces of ABS wire. Wheels and blades are reinforced by smaller circlets inbetween. Once you’re ready, start by gluing the base with all sides of the car (left-right-top), plus the dividing wall inside. You can proceed to insert the sticks with the horizontal sprocket and the wheels. Test the distances first. Please notice the lower part of the vertical stick must not be glued against the stage. The mechanism must work so that the horizontal sprocket touches and pushes the vertical sprocket. Once the mechanism runs with no glitch, you can glue each sprocket in that precise position.
