We used a serial-to-USB converter to be able to upload images to the computers, each of which has enough space for four different images, allowing us to create animations or just to display a rotating set of images.
For my first go, I tried a portrait of Carl Sagan. Because we only have one color, I had to find a simple portrait that was easy to reduce to a single color. I found this one on Google Images, and turned it into this.
SpokePOV Kit – v1.1 – One single SpokePOV fits in one wheel, you can add as many SpokePOVs to a wheel as you’d like get a better image. With one spoke, persistence at a speedy 15mph. Two spokes for cruising at 10mph. Three for a leisurely 7mph! Read more about specifications, full instructions, usage, etc. at the SpokePOV webpage. (read more)

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
