WaterColorBot + littleBits by Super Awesome Sylvia. She’ll be demonstrating it at Maker Faire this weekend!
Code for the project is here.

Fab Academy CNC Workstation Cart
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.
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.
Blinky AVR Earrings
Look what just arrived in the mail– Blinky AVR Earrings!
Not long ago, Rick posted on twitter about the ATtiny84 blinky earrings he had made, inspired by my voltage regulator earrings (which I now fasten on with the appropriate phillips screw).
Four blue LEDs blink in sequence, powered by a CR1220 battery. The board is traditional OSHPark purple, with an ISP header for convenient reprogramming. They’re lighter than they look and quite comfortable.
Thank you, Rick! I know what I’ll be wearing to Maker Faire!
RoboGames Wrap-up
We had a great time at RoboGames demonstrating the EggBot over Easter weekend. Thanks to the contestants in both Combat and Bartending Art Bots categories that we were privileged to judge.
Congratulations to our friend RobotGrrl, who took home a gold medal in the Best of Show category.
Congratulations also to our collaborators on the WaterColorBot project, Schuyler and Roger who won gold in Art Bots in the Painting category.
STEM at the White House Easter Egg Roll
From the White House Office of Science and Technology Policy blog post, An Egg-straordinary Day of Science and Technology:
Interacting with EggBot, an art robot that can paint very intricate and precise designs on eggs. EggBot taught students about digital design, computer numerically controlled machines and robotics. This was also a fun way to celebrate National Robotics Week!
Pattern Generator for EggBot
Kitti wrote:
My husband made something amazing for the eggers again! He programmed a pattern generator that enables you to create triangle or square-based patterns. The output is an svg file that can be plotted on an egg.
What a great way to play with the EggBot!
From the Mailbag: Interactive Game of Life
Forrest shared these pictures of his Interactive Game of Life build.
I bought the project to help expose my two grandsons to electronics and learn how to build circuit boards. Dan my 10 year old did one board all by himself just using your instructions. Josh my 14 year old did more than half of the boards and I finished them up because I only have the kids for limited time periods. I am so proud of them. Josh complete understands how the Game Of Life works…I don’t HA! We are planning on adding a instruction board to the bottom of the display so other kids can have fun.
I have a CNC router and built the frame. The boards are screwed onto a piece of 1/4″ plywood which floats in the frame. Not glue in. I machined a loose slot around the inside frame pieces. That way I can take the frame apart and easily change out of a board if necessary. It has been so much fun to build and you have SUPER service.
We thank you so much and would like to build more projects that you may come up with. As soon as I get more time with Dan we are going to build the clock.
He also shared his case design (105 kb dxf). Thank you for sharing your time and skills with your grandkids, and for sharing your pictures and design with the rest of us!
Floral egg by Kellbot
Kellbot posted this video of the EggBot drawing the lovely Paisley Flower Egg design she has up on Thingiverse.
It turned out great!
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!
St. Patrick’s Day EggBotting
Happy St. Patrick’s Day! Thanks to A.Z. for sharing these photos of ornaments decorated with shamrocks using the EggBot.
