MAKE pal Todbot posted up his slides from Sketching with Hardware, it’s good stuff, he writes – “My talk was “USB on Rails”. The USB HID standard enables the sending and receiving of arbitrary data-structures (“objects”) between a host PC and a device. All without any additional device drivers, since the HID driver is built in to all OSs. Many sketching tools or demos use USB, but introducing them to the unintiated means lots of reboots for driver installs. The title is a silly, but half-serious, take of applying the philosophy of Rails to hardware-to-computer interfacing: solve the common case simply, but allow deviations. More on this later, for now, here’s my talk’s slides”Link.
