Engineers are constantly being frustrated by the inability to conveniently draw circuit diagrams, but the iSketchnote digitizing iPad cover is the perfect add-on since it allows plain-paper sketches to be automatically uploaded to any iPad. The iSketchnote is enabled by an array of 32 STMicroelectronic magnetometers which locate a passive pen with a ring magnet attached: R. Colin Johnson @NextGenLog
