What do you get when you combine a laser pointer, pillbox, and an Arduino? If you’re maker Raul Aguaviva, you’ll get an awesome DIY laser projector, of course. In addition to its relatively spartan design, the creative use of a heptagonal pillbox for a polygon greatly reduces the overall cost and complexity of the device.
Well, I finally get to let the cat out of the bag. We’ve got Pixel Qi screens available in the Maker Shed as of today.
Blinking lights are good, right? String enough of them together in a circle and you have a pretty interesting display. Maker Don Roberts builds such a display. It’s called the Novetron Mark I and it’s available in Makers Market.
Inspired by a heating pad they purchased, Windell and Lenore of Evil Mad Scientist Laboratories show how to make a fake seven segment display.
Ian from weezey.com wired up a couple of Peggy2 light emitting pegboard kits to an Arduino and with a couple of tweaks to some existing code managed to get the display to run across both units.

A look inside of the fireworks and how they go about painting the sky with fire, light, and color.
