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.
After a recent conversation we had on twitter about edible hot glue possibilities for gingerbread houses, Ben Krasnow modified a hot glue gun to melt chocolate, adding PID temperature control. He also made a mold for making chocolate sticks of the right size for the modified glue gun.
Darren posted pictures of his UV erasable coffee table which was inspired by our 555 footstool.
The top lifts to reveal the compartment inside and to provide a taller table surface.
There are lots of build photos in the imgur set, and more details in the reddit discussion.
From @fabsterdam on twitter:
We are also setting up the Christmas tree. Painting balls with the eggbot.
The file is available on Thingiverse.
We were sent a picture of handsome cat Gandalf with an array of green Octolively kits all built up.
Mr. Pumpernickel also looks great in the green glow. Both Gandalf and Mr. Pumpernickel are continuing in a longstanding tradition of cats and interactive LEDs.
Harley Cat (who passed away a few years ago) helped test our very first interactive LED project: our Interactive LED Dining Table.
Jellybean helped demonstrate a later project: our interactive LED coffee table. She is featured at about 48 seconds into this video.
Joyce wrote in this year with her latest Pez Menorah (using our Deluxe LED Menorah kit), featuring a Star Wars theme.
She also wrote up a thorough set of instructions on tumblr, which looks like a remarkably easy way to publish a step-by-step tutorial without using a platform like instructables. It may take some getting used to reading chronologically, but it is effective.

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.
After seeing our Larson Scanner kit, Martin shared this LED metronome project with us. Martin says:
It was designed as a “Visual Metronome” So a learning music student could help see the timing by watching the green light. There was to be an optional clicking sound by using a small solenoid for the ticking – I chose that in place of a speaker for a more authentic sound.
The timing is a standard 555 timer which is fed to 7442 BCD to DECIMAL counter. Next chip is a 74193 UP/DOWN counter. When the count hits the last number, it sends a pulse to reverse the count or start over – depending on the toggle switch on the side.
There is also a pot on the 555 to control the speed. All this was made in one night while I was working the graveyard shift.
The entire LED display was hand wired using a manual wire-wrap tool.
The chip pin labels on the back of the perf board are a particularly awesome relic of a different era of electronics assembly. Thanks for sharing your project photos and video with us!
