After going through photos of Lanthea Cosplay’s striking Little Mermaid costume, I saw she referenced tutorial videos from Phaleure Cosplay. Phaeleure goes over every step of creating a mermaid bracer from Worbla from making the pattern to decorating. You can obviously take the information and apply it to any kind of bracer or watch it for some general advice on working with the versatile material that is Worbla.
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.
