Here is a preview of new version of the multisensory cushion controller box. Unlike the previous version, which used an Arduino Uno and Adafruit Waveshield, this one uses a Lilypad MP3 player and is powered by a LIPO battery (not shown in the images). The battery is plugged into an Adafruit lipo charger, which is permanently connected to the MP3 player. The Lilypad MP3 player has built-in amplification which is loud enough to power the Visaton K50 speaker without needing an external amp. This new controller box is about 20mm thinner than the last version, and shorter. The whole controller box is 140mm x 70mm x 25mm and about 100g with the battery.
