48hour physical prototyping project creates the Knock Clock

first_imgSometimes if you give an individual or group a limited time in which to create something you get surprisingly good results. This is why so many great games appear from the Ludum Dare competition that only allows 48 hours to create a prototype game.The same is true if you apply a similar time limit to a physical design challenge. In this case, groups of students at the Copenhagen Institute of Interaction Design (CIID) were given 48 hours to design something that was a physical prototype. One team, comprised of Giorgio Uboldi, Gijs Huisman, and Michael-Owen Liston, came up with this rather novel Knock Clock prototype.The Knock Clock looks like an ordinary wooden box, but it is both a clock and an alarm. By knocking on the top of the box twice the box responds with the appropriate amount of knocks telling you the time to the nearest 15 minute interval. First you get knocks with a long interval for hours, then shorter intervals for the 15 minute marks (15, 30, 45 minutes). So 3:30 would be 3 long interval knocks followed by 2 short interval knocks.In order to use the alarm function you have to cover a sensor on the top of the box before knocking the number of minutes you want to wait before the alarm goes off. The Knock Clock confirms the alarm being set with a single knock. Then, after the correct amount of time has passed the alarm knocking occurs. We also hope and assume you can set the alarm to go off after several hours, not just minutes.Check out the video below for a demonstration of how it works.This definitely isn’t a clock for those of you in a hurry or who need very accurate time keeping, but it’s certainly different. The fact it doesn’t have a display is going to appeal to some people, and with a little refinement I bet this could be turned into a very popular, and commercial clock.via Adafruit Industrieslast_img
