The ground work for this project started in a senior design project. Our team mates are now looking to expand the idea and continue developing our product so that it can be enjoyed by everyone! Prototyping was done using the Arduino Due and Sparkfun Jamboree boards as seen in one of the figures. There are plenty of pocket size amplifiers on the market, but not many that have Bluetooth, a touchscreen interface, and an SD card interface that still retain their high quality amplifier traits. This one does it all and will really bring out the detail in your music. The Atmel chip is highly programmable so we have lots of headroom to continue designing our interface. This is a work in progress so UI work is still needed.
cool gadget, got my vote. Nat.
