Parking Attendants Hate This One Trick™

I love it, what is it?

A self-adjusting blue parking disk. They’re used throughout Europe and typically used to show that your car has been parked in a spot for less than an hour. But beware the blue badge, for it is a fairweather friend. On those days you’re a little longer than expected, it becomes a telltale tit! 

There are solutions that constantly update the time, but that’s not quite sneaky enough for us. We’ve made something to simulate you nipping back to the car before the hour is up and resetting the time to give yourself another hour. 

And that’s it, an easy little exercise in giving you one less thing to worry about using a bit of arithmetic and some soldering. We’re obliged to say ‘Don’t do this’ because we do not approve of gas-lighting Traffic Wardens.

Even though we’ve said you shouldn’t, and you shouldn’t, we’ve shared all the code and 3d print files - just in case you find them useful.
