Announcing Little Helper!

I decided to focus on these features for my Little Helper.

Small (iPod sized)
Unconnected, i.e. battery powered and rechargeable
Easy to use User Interface, i.e. TFT screen
One handed operation
Support for 3.3V and 5V
DAC output
Fast MCU
Enough RAM for a larger software project
Arduino compatible
One button is enough design

Today, when building mobile devices one might think about touch displays. I decided to not use them because they do not allow for good, precise single handed operation, and I think that is an important feature for my Little Helper. The second best interface for small devices is a click wheel. Hundreds of million sold iPod seem to prove that.
