David Reyes, aka Tuxbrain, one of the Arduino distributors in Spain, has just brought to life one of the coolest hacks I have seen for some time. He managed to reflash Arduino Uno from a Ben NanoNote. He has implemented a text-based IDE that can reflash the boards directly from the NanoNote without using external power. If you want to have a device to reprogram your ATmega processors without having to bring your computer around, this can be a great solution. Just remember, this is an advanced hack, you should be familiar to the use of CLI (Command Line Interface), but David has promised taking a look at Qt-creator and put together a small text editor with uploading capabilities. Stay tuned at Tuxbrain’s development website!
