I’m not exactly sure what stream of thoughts lead to this idea. I had been looking for an interesting way to use optics or lenses on a ring or necklace. Days of searching early thoughts lead me to other ideas and still other ideas. I tested various lenses I had lying around trying to make something cool happen until I gave up and decided to create something that works with natural optics. A pinhole camera requires only an aperture (pinhole) and light. I found an old cheap pocket watch I had lying around and set to work trying to make everything fit within.
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.
