Blinky Light Combination Lock Keeps Aliens out of Your Quarters

When I see scifi picture show from the sixties and 70s , I always love the blocky , blinky lights on all the computers . Though they were obviously considered “ futuristic ” at some level before we all started fetishize miniaturisation and motion - base computers . But now the DiY geeks over at Hackaday have found a manner to make those blinky blocks into something useful : a computer keyboard combining lock . rather of keying a number sequence into it , you could distinguish a people of colour sequence . It ’s a bang-up base electronics project , and it make your front threshold look like it should afford with that Star Trek “ fffwwp ! ” noise .

Here ’s how it works : When you press each key , it cycles through three colors . You press the color you desire . When you ’ve got your color pattern set , all the lights show off light-green and the room access opens . Obviously , if you require to be safe , you ’ll need to figure out a direction to harbor the keypad while you ’re unlock it ( this is a good idea with routine - based computer keyboard too ) .

you’re able to go through all the steps to make this lock , from circuit boards to LEDs , or you’re able to buya pre - made keypad here . You ’ll still have to program it , though !
