The twinkling lights dotting the ceiling of this dazzling cave system are the work of arachnocampa luminosa, a bioluminescent gnat larva (also called a glowworm) found throughout the island nation of New Zealand. It is believed that the light, emitted mostly from females, is how the insects find mates. These long-exposure photos by local photographer Joseph Michael capture small communities of worms amongst 30 million-year-old limestone formations on North Island. You can see more shots from the project titled Luminosity, here.
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.
