Steve Davee, whose Maker’s Notebook hacks we’ve covered before, sent us a progress video. Here, he shows the LED binary indexing cover he introduced in the Maker Faire video, and a second project, to put a membrane keypad and LEDs in a cover that will eventually hook up to a microcontroller and will respond to various environmental variables, button presses, etc. He also teases a third Notebook that’s been hacked by one of his students (he’s a grade school teacher).
