Bastian sez, "Tinkerforge offers open source electronic building blocks. There are sensing-, motor controlling- and wireless building blocks. You can select the modules you need for your project, plug them together and with only a few lines of code you can program your system. You can control it from your PC/Mac, tablet or smartphone."
Tinkerforge (Thanks, Bastian!)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
