After seeing this Instructable about controlling the Eggbot with a Raspberry Pi, it seemed like a great thing to bring to MakerFaire. I had a small LCD screen handy (although it’s pretty low res) so it should work perfect for computerless demos and not take up too much space.
Starting with an EggBot built from the Evil Mad Science Laboratories kit, we embed a Raspberry Pi Linux board into the EggBot. This required that we installed Inkscape, the eggbot extensions and VNC server software; next we installed VNC client app onto an iPad and an iPhone (only the iPad is shown in this video); We connect the USB from the Pi to the EggBot board and connect power to both boards; now we have an autonomous EggBot which needs no external computer, keyboard, mouse or monitor — all controlled wirelessly from iPad or iPhone.
The Original Egg-Bot! – Deluxe Kit! – The Eggbot is an open-source art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball to that of a small grapefruit– roughly 1.25 to 4.25 inches in diameter (3 – 10 cm).
The Eggbot is super adjustable, and is designed to draw on all kinds of things that are normally “impossible” to print on. Not just eggs but ping pong balls, light bulbs, mini pumpkins, and even things like wine glasses– with a bit of work. See the photos above for some examples of personalized golf balls, christmas ornaments, light bulbs, and (yes) eggs. (read more)

John did a nice job! Glad my instructable & youtube videos were helpful. Just a note: using eggs in the eggbot is not necessarily wasteful — just blow them out and enjoy scrambled eggbot eggs after you print on them. Thanks Adafruit for great Rpi and eggbot products and tutorials.
