The Rose of Jericho (Selaginella lepidophylla) is a species of desert moss that has the amazing ability to ‘resurrect’ itself after bouts of extreme dehydration lasting months or even years. After just a few hours of exposure to moisture the plants burst to life, uncurling from a tight ball of dry leaves to a green flower-like shape. Videographer Sean Steininger shot this timelapse of several plants as he exposed them to water.
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.
