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.

A Lego Mosaic Printer

JK Brickworks made this amazing “pick and place” style Lego Mosaic Printer:

It is built entirely using LEGO parts. It first uses the EV3 colour sensor to scan the source image and save the data on the Mindstorms unit. It can then print multiple copies from the saved image data. The 1×1 plates used for ‘printing’ the mosaic are supplied using a gravity feed system and the printing head is simply a 1×1 round plate that can pick up and place the 1×1 plates.

More information about this project can be found at JK Brickworks.

WaterColorBot and BeetleBlocks

The Tinkering Studio posted on twitter:

BeetleBlocks is a system for enabling people to explore algorithmic 3D geometry by snapping together Scratch-like programming blocks.

They posted a picture of the finished painting, which looks awesome.

Fab Academy CNC Workstation Cart

CNC Workstation cart from Fab Academy
Erin posted on the Make blog about large scale CNC projects at Fab Academy, including a CNC workstation cart based on our design made by Lina Monaco. Lina goes into more details in her post here.

To design it I started from the Evil Mad Scientist’s CNC Workstation Cart redrawing to adapted it to our necessity as an horizontal PC, cables space inside, and last but not least without any screw or glue.

No screw no glue drawers

She posts about her design process, including prototyping using a laser cutter to make a scale model. It looks great—we especially like the cutout drawer handle design.

Meggy Jr RGB + WaterColorBot

Our friend Schuyler hooked up our Meggy Jr RGB hand-held video game platform up to control the WaterColorBot. He wrote on twitter:

I got the @EMSL Meggy Jr RGB working with the @MakerSylvia WaterColorBot. My code is here. https://github.com/docprofsky/meggyjr-cncserver.

The output looks great, too. Thanks for sharing your code, Schuyler!
