Human bones make great architectural models, and they could also inspire the next renaissance in sustainable architecture.
If you’re designing a building, a lot depends on the materials you choose. Human bones are made from a composite, a fifty-fifty combination of calcium and collagen. Hydroxyapatite, the calcium compound, is incredibly strong but brittle—alone, it snaps as soon as it reaches its weight limit. Think of a bridge of diamond, another brittle material. “We would never build a bridge out of diamond, not because it’s expensive but because it’s so brittle,” says Ahmed Elbanna, a civil engineer at University of Illinois Urbana-Champaign. “It can carry a tremendous load, but if the load exceeds its strength, it will shatter without warning.” In your bones, the malleable collagen adds a flexible strength to the calcium, protecting your bones from shattering every time you do vigorous physical activity.
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.
