EggBot in Budapest

Kitti in Budapest has a thoughtful blog about her EggBot. She’s posting her experiences, modifications, and challenges. She is putting up designs on Thingiverse, starting with the Hungarian Folk design shown above.

My first design was inspired by my Mom. I told her about my plans to draw something in Inkscape to be printed on an egg later. She immediately ask if I am planning to do a Hungarian folk pattern.

We’ll be looking forward to seeing what comes next!

GeekDad on the EggBot

Mark has posted a nice writeup at GeekDad about receiving an EggBot as a birthday present:

It was the perfect gift for a GeekDad–something I wasn’t expecting and might not have bought for myself, but is so much fun that I wish I’d bought one years ago.

30 valentine ping pong balls

He used it for his daughter’s preschool:

In almost no time, I had a box of 30 Valentine’s ping pong balls for her to take to school. Her teachers were fascinated when they saw them and I was told had been debating whether we had somehow hand-drawn them all. The head teacher asked my daughter how we made them and she naturally replied: “No, a robot drew them!”

EggBot holiday project roundup

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.

Ostrich EggBot 2.0

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.

Ostrich EggBot

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.

Pumpkin Faces for EggBot

Pumpkin Face

renegade_geek posted a set of Pumpkin Faces on thingiverse for the EggBot. They’re cleverly arranged in layers so that you can hide and show the different eye, nose and mouth options.

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.
