A Diamond Engraving Tool for Eggbot

Driver board with pen arm

 

What is it? It’s a most useful little thing: a low-cost diamond engraving attachment for the Eggbot.

 

This turns a humble pen-plotting Eggbot into a full-on CNC-driven vibrated-tip diamond-point engraving tool, capable of light-duty marking and engraving on hard materials like glass, stone, and ceramic. Wooo!

Hershey Text: An Inkscape extension for engraving fonts

header-fonts2

Hershey Text is an Inkscape extension that can render a line of text in one of several stroke-based “engraving” fonts. This extension solves a persistent problem, and one which we have come across in many different contexts: How to easily create simple and readable vector representations of text.

Quick start: Download and install the EggBot extensions for Inkscape, which now include Hershey Text. Much more information follows.

Maker Faire and Eggbot on Martha Stewart Show

Egg-Bot

 

If you happen to be into TV and/or Eggbot, you might want to tune into the Martha Stewart Show on Wednesday, Oct. 20. Our collaborator, Bruce Shapiro, inventor of the Eggbot, will be on as a part of a special episode about Maker Faire which will show off some of the cool things that Martha and her colleagues discovered at Maker Faire New York. After the show is broadcast, you should be able to find photos and video from the episode here.

Printing on a strangely shaped egg

One of those questions that keeps coming up about the Egg-Bot is, “Does the surface have to be perfectly smooth?” Or sometimes just, “Can you print on a golf ball?”

While we wouldn’t go so far as to say that you’ll have good luck printing on a tennis ball, it turns out that the surface doesn’t exactly have to be flat either. Golf balls certainly aren’t a challenge. And, as you can see above, you can even plot on strangely shaped “eggs,” so long as the surface is smooth enough that you can drag a marker along. Neat.

Update: We’ve posted some tips on using the Eggbot with pumpkins here.

Maker Faire Detroit Pictures and Highlights

Maker Faire Detroit

Maker Faire Detroit was a blast! It was held at The Henry Ford, which is a museum worth visiting in its own right. It is an amazing place we didn’t get to see nearly enough of and would love to go back and visit again.

In addition to providing a history of American manufacturing and a showcase of amazing vehicles, they have Mold-A-Rama machines!

As usual, one of the most exciting things about Maker Faire for us was meeting and talking with other makers. We got to talk to the participants in an aluminum casting demonstration, who were using foam that was carved onsite with a CNC router.

We also really enjoyed our neighbors at the faire with the Note Grinder, a machine that read player piano rolls optically and used door lock actuators to press the keys on a synth keyboard. We were impressed with how pleasant it was to listen to (even for two days straight!) especially with the rhythm accompaniment provided by the actuator motors.

The fine folks at Context Furniture were passionate about the renaissance of craftsmanship in Detroit and had great stories of reclaimed buildings.

We were tickled to see several Evil Mad Science kits integrated into Maker Faire projects: a Peggy 2 being used as a readerboard, Wes and Don‘s 3D POV display with a Peggy 2LE, and Matt Mets’ Meggy Jr Sr.

Our Eggbots performed like champs, and we even tried out engraving on glass holiday ornaments during the faire. The engraver scratched away the paint on the surface, and as you can see in the top picture, they were beautiful when lit from within by an LED.

We didn’t come close to seeing everything, but we’ve put pictures of some of what we saw in a set on flickr.

We hope to see you at Maker Faire New York!
