While the 3D renderings look like something more appropriate for this month’s Halloween coverage, the idea of a customized 3D toothbrush is pretty interesting– Blizzident is just that (via Quartz):
All Blizzident-bristles are tailored to your own teeth. They are placed on the surface of your teeth in a 45 degree angle. They are also aligned exactly along your gumline in a 45 degree angle.
Additionally there are interdental bristles between all your teeth.
For tailoring we use a 3D model of your teeth (created from an impression or scan of your teeth by your dentist).
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.
