A new study of Rembrandt’s self-portraits provides more evidence to theories that the 17th-century artist, among other Old Master painters, used optics to produce his remarkably accurate works. Researchers Francis O’Neill and Sofia Palazzo Corner recently published their paper in the Journal of Optics that explains how various setups of flat and concave mirrors, all widely available during Rembrandt’s time, may have created projections the artist could precisely trace.
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.
