I have a Google Alert set on the term "Practical Arduino", and it often finds me very cool things that people have done using projects described in the book. One of those tidbits was this: batchpcb.com/index.php/Products/31584
I don't know anything much about it other than what's shown on that page, but from what I can deduce it's the circuit from the Virtual USB Keyboard project converted into a nice PCB with a bunch of buttons included for controlling games running under the arcade machine emulator MAME. I love seeing stuff like this, so if you've created anything based on things you've learnt from Practical Arduino please send me an email and tell me all about it!
