Today we are releasing our newest set of “Download and Print” cards for Valentine’s day. This is our fifth year, and fifth 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.
This year’s set features relativity, atomic orbitals, exponential growth, an LC resonator, and an epsilon delta declaration of love.
“You put me in an excited state.”
Roses are red. Which does suggest that they’re moving away from us, quickly.
While this sounds much like an “epsilon delta proof,” it lacks the logical rigor that we would normally associate with one. It’s more of a postulate, really.
“You make my heart feel like sin(1/x)….” If your heart isn’t jumping yet, you’ve probably never tried to graph that.
The original title for this one was “my love for you grows exponentially.” But hey, your valentine is smart (or you wouldn’t be sending these kinds of valentines): Let them do the math.
You can download the full set here, which includes all 30 designs from all five years (a 1.5 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.
Update: New cards have been released! Please check out the 2018 set, which contains all 36 cards from 2013 through 2018.

We are pleased to introduce the AxiDraw V3, a new generation of our flagship writing and drawing machine.
This new AxiDraw has been redesigned from the ground up for high performance. It features smooth rolling wheels on custom aluminum extrusions, specially designed for high stiffness and light weight. Its sturdy, rigid construction gives it finer quality output and in most applications allows it to operate at up to twice the speed of the previous AxiDraw, which it replaces.
As with the previous version, AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with 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 body of the machine, making it possible to draw on objects bigger than the machine itself.AxiDraw V3 is available to order today, and begins shipping next week. See it in action and learn more on the product page.
