A custom-designed speed board — those radar-equipped digital signs that tell drivers how fast they are moving — will be unveiled this summer that sends a spooky message to lead-footed New Yorkers: a gaunt LED skeleton appears whenever it detects a car exceeding the 30 m.p.h. limit on city streets.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

A minor downside – some drivers will speed in order to trigger the hidden image…
Some 15 years ago the local authorities here had an idea for a /brilliant/ system. A board telling you how much you exceeded the speed limit to warn you and to make you slow down. The local youth quickly made use of it to figure out who’s pimped car was going the fastest.
They /fixed/ that by adding a separate speed trap with camera not to far behind the board. The local youth moved on. Then someone argued what good the warning display was when you got fined in any event. So, to save some maintenance cost they replaced the electronic board with a simple traffic sign, showing the speed limit and they kept the speed trap.
Later someone figured the traffic sign didn’t make much sense, because normal traffic regulations already dictated the same maximum speed. They removed the sign.
In the end they ended up with what they should have started with in the first place, a speed trap.
