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:
- The art of transcribing old documents
- 3D Print your own Digi-Comp II
- WRL Technical Note TN-13, April 1, 1989: Characterization of Organic Illumination Systems (139 KB PDF)
- Examples of legal and illegal LEGO assemblies with explanations of why: Stressing The Elements (1 MB PDF)
- Ken Shirriff on Reverse-engineering a hybrid op amp module
- How to make a Super-Hydrophobic Labyrinth Game (YouTube)
- maker.js: A library for creating and sharing modular line drawings for CNC and laser cutters.
- Plotter People #2 is happening on March 13 in San Francisco

Today we are releasing our newest set of “Download and Print” cards for Valentine’s day. This is our seventh year, and seventh 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. The 2016 set featured Pluto’s cold heart, and the perfect card for your robotic expression of love. In 2017 we featured atomic orbitals, exponential growth, and an epsilon delta declaration of love. The 2018 set featured normal force, stable equilibriums, and something about RPN calculators.
This year’s set features geometry, division by zero, batteries, a nod to quantum chromodynamics, and two very bad puns. (Sorry not sorry.)
To the extent that it is important that romance is rational, this is an extremely romantic card.
A proton or neutron is made up of three quarks, but its mass turns out to be dominated by chromodynamic binding energy, not the mass of those quarks. Corollary: By weight, humans are almost entirely binding energy.
Unlike most Valentine’s cards, which neglect the vast majority of your potential paramour, this card will let them know that you appreciate more than a tiny fraction of them.
I tried to compute my love for you but my calculator gave me an error.
Like a LiPo battery charged at the proper rate so that it does not explode.
You had better be positive before you give this card to someone.
You can download the full set here, which includes all 42 designs from all seven years (PDF, 1.8 MB).
As usual, print them out on (or otherwise affix to) card stock, personalize, and [some steps omitted] enjoy the resulting lifelong romance.

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

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.
