I want to make a timer device for an outdoors-type game. I need it simple, cheap (should have to build several) and preferably non-powered, which would make an egg timer perfect.Except, there's a complication. The timer is supposed to be set to 1 minute, no less. And in the heat of the moment, making sure it's wound to 1 minute, not 50 seconds, is impractical.So, the solution is an egg timer (or similar) that won't be free to count down until wound to 60 seconds, or can only be wound to that, for whatever reason.Does such a contraption exist? Or (much more to my satisfaction) is there a simple way to build it? via /r/DIY http://bit.ly/2ANaufz
