Instructables Egg Contest

We’re excited to be partnering with Instructables for the Egg Contest 2016.

It’s springtime, the season when eggs traditionally get their moment of glory. In the Egg Contest we want to see what happens when you scramble up your creativity with this theme. Any and all entries highlighting or featuring eggs (or egg-like creations) are eligible.

Prizes include the EggBot Pro and Deluxe EggBots. We’re looking forward to seeing your entries!

Stroboscopic patterns for Easter eggs

Jiri Zemanek from Prague sent in this fabulous video of eggs decorated using the EggBot, some with markers, and some with the Electro-Kistka.

Various patterns are generated in Matlab using mathematical equations similar to ones describing Spirograph (or harmonograph) and Phyllotaxis. The patterns are calculated in such a way that when rotated under a stroboscopic light of suitable frequency or when recorded by a camera, they start to animate. It is kind of zoetrope— early device for animation. … Eggs are rotated at a constant speed, special for each pattern, by a brushless motor. No computer graphics tricks are used in the video.

Additional information is available at their site.

Introducing the AxiDraw

AxiDraw drawing machine

We are very pleased to introduce our newest art robot: the AxiDraw.

The AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with your favorite fountain pens, permanent markers, and other writing implements to handle an endless variety of applications. Its unique design features a writing head that extends beyond the machine, making it possible to draw on objects bigger than the machine itself.

The AxiDraw is a fantastic machine for making art — along with all those other things that you might use a pen-wielding robot for: Making “hand written” invitations, signing forms, or making neater whiteboard art than one might otherwise be able to.

AxiDraw is available to order today, and begins shipping next week. See it in action and learn more on the product page.

Evil Mad Scientist Valentines: 2016 Edition

2016 valentines

Today we are releasing our newest set of “Download and Print” cards for Valentine’s day. This is our fourth year, and fourth set of cards: The 2013 set had six equation-heavy cards, the 2014 set was a set of six symbol-heavy cards, and the 2015 set included love, hearts, and arrows.

This year’s set of six new cards features a note about warming Pluto’s cold heart, at least one embarrassingly bad pun, and the perfect card for your robotic expression of love.

Solve for x
“I was supposed to solve for x. So glad I found u instead.”

Pluto heart

And, from the distant reaches of our solar system:
“Just knowing you’re out there warms my heart.”


“ROSES ARE RED
VIOLETS ARE BLUE
THIS VALENTINE AUTOMATICALLY
GENERATED FOR YOU”

2016 valentines

You can download the full set here, which includes all 24 designs from all four years (a 1 MB PDF document).

As usual, print them out on (or otherwise affix to) card stock, personalize, and [some steps omitted] enjoy the resulting lifelong romance.

EggBots in Library Makerspaces

The New Sarepta Library in Alberta, Canada posted this video on twitter saying:

Our new EggBot is up and running! Come check it out!

We’re super happy to see libraries including our tools in their makerspaces.

Stippled Utah Teapot

Untitled

A Utah Teapot is an ideal design for a geeky ornament. For this one, I generated a vector stipple drawing from a photograph of the source object for this digital design icon. There are certainly many other ways to create a Utah Teapot ornament, including, of course, 3D printing.

In this case, I took our photo of our teapot, adjusted it to give it slightly higher contrast, and loaded it into StippleGen 2.

I removed any background stipples and plotted it on an ornament. The ornament is 2.6 inches in diameter and I used a 0.2 tip Copic Multiliner SP. I have posted the design on thingiverse.

Star Wars Holiday Ornaments

Imperial crest & Rebel Alliance Ornaments

We’re getting into the spirit with a couple of seasonally appropriate decorations. The Rebel Alliance Ornament and the Imperial Crest Ornament for EggBot are both available on thingiverse. Our guide to printing ornaments with the EggBot may be helpful, too.

Both designs are derived from a set of silhouettes from vecteezy.com.

EggBotting with Metallic Pens

Our friend Fran has been making holiday ornaments with the EggBot and writes:

I just wanted to let everyone know that I have finally gotten to be able to use the Pilot Gold/Silver Markers.

She suggests dividing the drawing into layers so that after each layer you can take the pen out to shake it to keep the ink flowing. We’ve added her tips to the wiki page about choosing pens for the EggBot.

If you have other tips for which pens you like to use or for working with ornaments, we’d love to hear about them!
