I got my sister an Eggbot for her bday – we got the most amazing presents! What a wonderful experience.
It’s close to the holidays, which means people are pulling out their EggBots and getting creative. Last year, we posted a set of holiday designs and some tips for working with ornaments. Here are a few projects we’ve found this year.
Erin Ruppert made this lovely “First Christmas” ornament. The gold ink looks great on the clear ball.
Erin also made ornaments with ornaments on them, which somehow seems fitting.
Lotte made an ornament for her mom at FABKlas, a maker education program.
The folks at FABsterdam made this Mario ornament.
MAKE Ventura used gold Sharpie markers on a matte finish ornament to great effect. Other makerspaces are playing with their EggBots, too. The Johnson County Library in Kansas is doing Eggbot ornament tutorials in their makerspace.
Chris Lynas took the EggBot to “work and school Christmas fair raising money for charity – result: £200 in under four hours!”
Fran marked up eggs for a family igloo making craft party.
Lastly, our friend Miguel engraved glass ornaments with his EggBot.
The Exploratorium is holding their annual member holiday party and shopping night on Sunday, December 7 from 6-9 p.m. We’re excited to be there to show off some of our kits, including the EggBot, which will be available for sale. You must be a member to attend (need an excuse to become a member?), and RSVP by December 4.
We’ve just released version 2.0 of our Ostrich EggBot kit! This is the giant size EggBot. Like the smaller models, it’s a machine capable of drawing on the surface of all kinds of spherical and egg-shaped objects up to 6.25 inches (15 cm) in diameter, including large ostrich eggs.
This chassis of the new version is CNC machined from melamine-faced MDF, and laser engraved with markings and calibration scales. (The previous version was made of plywood; you can read about it here.) We’ve also updated the graphics, and rolled in a number of subtle improvements based on user suggestions and our own extensive experience with the machine and other members of the EggBot family.
With a relatively large chicken egg chucked into the holders, you can get a better sense of scale. (An ostrich egg is a terrible object to suggest a sense of size!)
The tailstock (the sliding portion of the right hand side) has been slightly redesigned for higher stiffness and better ease of use. The bulk of the stiffness in the directions that we care about (that is, in the directions where the chassis material is not strong) derives from the steel angle brackets, and the new tailstock helps to reinforce that for better overall rigidity.
One of the best things about the new chassis material is that it laser engraves particularly well, giving high-contrast, highly readable adjustment scales on the sides. And that makes it all easier to use in practice. All considered, this has turned out to be quite a nice little upgrade.
A collection of separate eyes, noses and mouths, each set on its own layer, for a customized jack-o-lantern/ghost face to be printed with the Eggbot. These were made to print on ping pong balls. You may need to adjust for eggs and other less regularly shaped items. I have included a “faces menu” PDF so that you can clearly review your choices. This was really helpful in a classroom situation.
We’re excited to be bringing the EggBot back to the East Bay Mini Maker Faire on Sunday, October 19. The schedule of presentations and performances covers everything from “The Importance of Junk” to minestrone making. The list of makers attending covers the gamut as well.

An EggBot is a compact, easy to use art robot that can draw on small spherical and egg-shaped objects. The EggBot was originally invented by motion control artist Bruce Shapiro in 1990. Since then, EggBots have been used as educational and artistic pieces in museums and workshops. We have been working with Bruce since 2010 to design and manufacture EggBot kits, and our well-known Deluxe EggBot kit is a popular favorite at makerspaces and hackerspaces around the world.
The EggBot Pro is as sturdy as can be: Its major components are all solid aluminum, CNC machined in the USA, and powder coated or anodized. (And isn’t it a beauty?)
The most common mechanical adjustments are faster with twin bicycle-style quick releases, and repositioned thumbscrews for easier access.
The frame also has an open front design that gives much better visibility while running, and greatly improved manual access when setting up.
And, it comes built, tested, and ready to use — no assembly required. Assuming that you’ve installed the software first, you can be up and printing within minutes of opening the box.
Jenslabs has published a thoughtful and thorough evaluation of a number of currently available rollerball and gel pens. He tested them using his Circlon machine.
One thing that anyone who as ever built a drawing machine realizes, is that to get quality results you need a quality pen. There are millions of pens out there, but after a little trial and error I realized that rollerball pens or pens with gel ink are the best pen types for my machine. Both rollerball and gel ink pens use a water based ink that is less viscous then the oil based ink used in ballpoint pens. The Circlon machine sometimes move very fast, so the pen has to be able to release enough ink to make solid lines even at high speed.
