Koi Fish swim gracefully underwater but, unfortunately for them, their view of the outside world is just out of reach. The Floating Fish Dome by Dutch company Velda solves this issue and allows the privileged fish to swim a bit higher than the pond’s surface.
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.
