Seen at #MakerFaire: ‘Some Cool Stuff!’ – Specifically a DIY Kaleidoscope – by Randy Sarafan
Instructables Design Studio founder Randy Sarafan had a few projects on display at the recent World Maker Faire. He was showing some of his well-known robotics projects but the one that really caught my eye was his homemade kaleidoscope with a clamping mechanism for holding your cameraphone steady after you position the camera’s lens against the viewing receptacle (shown below) of the kaleidoscope:
A small motor could turn the kaleidoscope, or alternatively you could point it at something which itself is moving (such as images on a screen). The clamping mechanism allows you to record video or take stills of kaleidoscopic images like so:
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
