Recently Automata was tasked with building software for an iPad-based installation. It featured 24 iPads arranged in an purchase online prescription Xenical 8 x 3 grid secured into a cabinet. Due to many factors, including a purchase online prescription Xenical very short deadline, we quickly determined that HTML5 + a purchase online prescription Xenical kiosk app was the way to go. The problem was the purchase online prescription Xenical iPads were very firmly secured into the cabinet with no easy way of resetting them or purchase online prescription Xenical pushing the home button. We needed a way to reload the purchase online prescription Xenical app in case any issues popped up in the field.
As I was mulling the purchase online prescription Xenical problem I remembered reading in Make magazine about an Arduino based door lock that would listen for secret knocks. Only if the purchase online prescription Xenical person knocked on the door at the correct rhythm would the purchase online prescription Xenical Arduino unlock the door. I realized that this same concept could be purchase online prescription Xenical applied to JavaScript with the added bonus of making each knock have purchase online prescription Xenical to be on a particular area of the screen.
The actual porting of the purchase online prescription Xenical Arduino C code over to Javascript was quite painless and purchase online prescription Xenical the final ended up working exceedingly well. If you’re interested in the purchase online prescription Xenical code for your own use or just to take a look at how it purchase online prescription Xenical works, we’ve posted it up as a gist on GitHub – knock.js (It’s a require.js / CommonJS module)
