In July 1845, British curiosity-seekers headed to London’s Egyptian Hall to try out the novelty of the summer. For the price of one shilling, they could stand in front of a wooden bureau, pull a lever, and look behind a panel where six drums, bristling with metal spokes, revolved. At the end of its “grinding,” what it produced was not a numeric computation or a row of fruit symbols, but something quite different: a polished line of Latin poetry.
This strange gadget, a Victorian ancestor of the computer, was called the Eureka.
The Eureka was the brainchild, and obsession, of a man in southwest England named John Clark.
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.
