Its key aspects are:-
- Touch sensitive (like a tablet)
- Pictures easily changes
- Sound files easily changes
- No programming skill needed.
| Pictures and sound files can be changed with minimal or low cost resources. The board uses capacitive sensing (like a tablet screen). It has up to 12 "hotspots" that will trigger any kind of sound (MP3 file). It could be a single note, a song or a single word or a poem. Associated pictures can be hand drawn and laid on top of the sensors. Sound files and pictures can easily be changed. It's aimed at supporting the development of speech skills in children with autism. |

The eBoard has 12 "Hot Spots". They are made of "EMI" copper tape overlaid with with gaffer tape. Touching any one of these hot spots will trigger a sound. Touch it again whilst the sound is playing makes the sound stop. A template helps to match sounds and images together. |

Bare Conductive: This is a multifunction board that combines.
|
 |
Amplifier Almost any amplifier can be used. This one has the advantage of small size, volume control and can run off 6-15v. It is worth checking that the voltage range fits in with the other components used (I have been caught out this way a couple of times). This is a "Class D" stereo amplifier that will happily run on 9v. |
 |
Voltage Regulator. As the eBoard is powered by a single 9v battery, an onboard 5v regulator was required to provide the 5 volts for the "Bare Conductive Board". This regulator can source up to 2.5 Amps so it is useful if a 9 volt amplifier is used. |
