There are a great many ways to celebrate Pi Day, and food is one of our favorites. While pie is obviously appropriate for Pi Day, there are so many other fun ways to explore math and science through cooking. Here are some of our food projects that can be great ways to explore math concepts on Pi Day:

I’m super excited to see the new MythBusters Jr episode tonight, because I’m in it with the AxiDraw!
In their quest to see if a single pencil can write 45,000 words, @valerie_mbj, @NotABombBunkE and @braintwist2112 turn to @1lenore's AMAZING #AxiDraw. But can it substitute for a human? Well … hmm. Don't miss an all-new #MythBustersJr TONIGHT at 8p on @ScienceChannel. pic.twitter.com/YDkOJzF78r

I had a fun time working with Valerie, Rachel, and Elijah, as well as the great crew.
Yesterday I gave a talk at the inaugural Plotter People meetup titled Plotter Projects from Evil Mad Scientist Laboratories. My slides were a series of pictures from our projects, so rather than publish the presentation itself, I’m publishing a list of links to all of the projects I talked about.
The first part of the talk was introductory information about Evil Mad Scientist with some example projects from our blog and our early kits.
- Interactive LED Dining Table
- Interactive LED Coffee Tables: Update and kits!
- Larson Scanner
- Fractal Snowflake Cupcakes
- Bristlebot: A tiny directional vibrobot
- Asteroids (the edible kind)
- Circuitry Snacks
The main part of the talk delved into all of our plotter related projects, including hacking plotters, things we’ve made from plotters, software we’ve made for use with plotters, and plotters we’ve made.
- An AVR-based Analog Plotbot with an E-Paper Display
- Solid freeform fabrication: DIY, on the cheap, and made of pure sugar
- Finally, CNC toast!
- The CandyFab 6000
- The Egg-Bot Kit
- Ostrich Eggbot
- The MarshMallowMatic
- Introducing the EggBot Pro
- A Diamond Engraving Tool for Eggbot
- The Egg-Bot Electro-Kistka
- STEM at the White House Easter Egg Roll
- Vector Snowflake Application
- SymmetriSketch: A simple app for playing with symmetry
- Operation: CNC Snowflake
- CNC halftones with ASCII art
- Hershey Text: An Inkscape extension for engraving fonts
- StippleGen 2
- Introducing The WaterColorBot
- White House Science Fair Roundup
- Introducing WaterColorBot 2.0
- Introducing the AxiDraw
- Introducing the AxiDraw V3
- AxiDraw V3 XLX
- AxiDraw V3/A3
- The AxiDraw SE/A3
- AxiDraw Accessories
- AxiDraw CLI (beta)
- AxiDraw Python API (beta)

There’s a new get-together just for plotter people!
Plotter People is a meetup for creative coders and people interested in collaborating with robots to make art. You’ll get to talk to folks who make generative art in a wide variety of programming languages and software environments, and you’ll get access to pen plotters and the people who make them.
The inaugural Plotter People meetup will be hosted at Github in San Francisco on Monday, January 14 at 6:30 pm. There will be two speakers, including Sher Minn, who will be talking about Recreating Retro Plotter Art, and me, Lenore Edman. I’m excited to have been invited to speak and I’ll be talking about the Plotter Projects of Evil Mad Scientist Laboratories, from the Analog Plotbot pictured above to the AxiDraw. There will also be time to mingle, talk, eat, and even play with plotters.The event is free, but please head over to the invite page to RSVP!
The stroboscopic patterns are designed in MATLAB and drawn by EggBot Pro on colored glass Christmas ornaments. Motion of the balls is controlled by custom mechanism built using components from two Prusa i3 MK3 3D printers, like six stepper motors and two Rambo boards. On top of designing the patterns, which is Jiri’s hobby (when he is not busy with research) and building the whole contraption in a very short time, the team had to deal with issues including non-spherical ornaments, or how to use Rambo board to precisely control the velocity profiles.
We love to see how people make things, and Jiri did not disappoint, sharing process photos of making the rotation mechanisms.
With great help from his colleagues Martin, Krištof, and Filip they took Christmas ornaments to the next level and taught them to dance!
The final setup shot captures how they created such a beautiful video.
Merry Christmas to Jiri and the Advanced Algorithms for Control and Communications group! Thank you for sharing your project!
For Hanukkah this year, Ol Rappaport modified one of our Deluxe LED Menorah kits into a custom fluorescent acrylic body, substituted UV LEDs and used a USB power supply.
He’s also having a give-away for his example basket!
