When the the little one has all the toys in world but insists in playing with thing that they shouldn't be playing with just make a busy board.

All the things on this board are mostly things that the family and I had laying around except the Raspberry Pi 3, the Adafruit Capacitive Touch HAT, and the conductive paint.

What it does

It has things that spin turn and flick but using the capacitive touch you can customize the sounds it can make by uploading .wav files to the Pi and directing the script to use the files. So when the any part of the stencil or drawing is touched it makes a sound.

Step 1: Supplies and Setup

Supplies

  • Raspberry Pi 3 (I tried to set this up on a Raspberry zero but had issues with outputting Python audio over a USB sound card)
  • Knobs / mirrors / door stoppers / buttons / fans / ect... Just make sure its not sharp or can harm your little one
  • Bare Conductive Paint or Pen
  • Paint brush
  • Single strand solid wire
  • Adafruit Capacitive Touch HAT for Raspberry Pi - Mini Kit - MPR121
  • Wood boards I used Medium Density Fiberboard 1/4 in. x 2 ft. x 4 ft for the front and back and extra 1/2x1/2 wood scraps to make spacing between them.
  • short wood screws
  • Copper plated nails
  • wood glue
  • Tape
  • Stencils because I am not much of a painter.
  • USB rechargable battery and usb powered speaker

Tools

  • Drill
  • Hammer
  • Saw

Assembling the front

  1. Cut your board in half to get 2 equal 2 foot boards and cut your 1/2 in boards to place between the front and back boards
  2. Lay out your board to get an estimate of placement leaving enough room around the outer edge for the 1/2 inch spacers
  3. Using the wood glue and a couple wood screws to mount the front board and 1/2 inch wood around the outer edge clamp it down and let dry.
  4. Mount your Items to the board just to make sure that its not going to protrude through the back board and not so short that it can be torn off.
  5. lay out stencils, use tape to help keep them on there and prevent paint from going where you don't want it.
  6. After letting it dry. Remove stencils then make sure to touch it up and connect spaces between them with a line . This is done to let the whole image become compacitive instead just a small part.
  7. Take your copper plated nails and lightly tape them into spots of each image giving you a connection from the front of the board to the back end of the front.
<p>Does the conductive paint images set off the sound by touching a single image? Or do you need to touch two items simulatneously to close a circuit?</p>
<p>it is set off by just tapping a single image. there are 12 different sounds that can be programmed on that hat.</p>
