Everything went smooth, very nice electronic documentation, easy to follow tutorial content. Clearly, it sounds the same as Arduino - but once you already worked with Arduino it is nice to try something "more hardware" where you build actually everything from single components. Inspiring!
P.S.: To tell you the truth, I got inspired by an article I just read on Make magazine about some guys teaching hardware and software Arduino development starting from bare components, no soldering - just breadboard. Amazing!!!
