Algae kaleidoscopes were among the many creatively biological ways that Victorian scientists entertained themselves. Using the end of a piece of hair, they moved tiny single-celled algae known as diatoms on a slide, arranging them into beautiful, symmetrical patterns that amused wealthy amateur naturalists at social gatherings.
Now, one artist in England, Klaus Kemp, continues this Victorian art of diatom arrangement.
“The first time I saw a diatom, I was 16,” Kemp says in the video by Matthew Killip. “It was love at first sight.”
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.
