Conductive Painting

We made a talking poster with Bare Conductive paint and touch board today:

 

The poster on the wall next to Simon’s room:

 

This is how we made it. We taped a stencil to a large sheet of white paper and applied the conductive paint, then waited for the paint to dry.

While waiting, we loaded several mp3 files on to the MicroSD card that came with the touch board. Simon made sure the files were named in the right order, to correspond to the correct electrodes on the touch board. We found the sound files at FreeSound.org:

Simon placed the MiscroSD back into the touch board:

We carefully removed the stencil, this was the result:

We attached the touch board and the speaker to the poster, then cold soldered the holes in the electrodes with conductive paint.

Let it dry and turn the power on!
