Last year we released a set of six equation-heavy ”Download and Print” cards for Valentine’s day. This year, we’re doubling the size of the collection (to twelve!) by adding six more cards, this time heavy in symbols, not equations:
“You turn me on” …with an SPST switch.
“I can hardly resist you.”
There is room for a future superconductivity joke here, involving a phrase like “I can’t resist you (below a certain temperature).”
You can download the full set — including the 2013 cards — here, a 500 kB pdf document.
As with last year’s set, print them out on (or otherwise affix to) card stock, and [some steps omitted] enjoy the resulting lifelong romance.
As part of the documentation for the WaterColorBot project, we’ve put together a compendium of information about commonly available watercolor paint palette sets. For each of the sets, we’ve tested to see how well they work in the WaterColorBot— in terms of physical size, color order, paint quality, brush quality, and so forth.
You can find the complete list on our documentation wiki site, here.
Our friend Doc Pop is running a kickstarter campaign for his new album Destroy All Presets to release it on a special edition Gameboy Advance cartridge. Even if you don’t back his campaign, the video, with its retro-style album ad, is definitely worth watching!
Over on the Wolfram Blog, they’ve posted the winners to the Wolfram Technology Conference Egg-Bot Challenge:
We have a programming competition every year at the Wolfram Technology Conference, which in past years was the Mathematica One-Liner Competition. This year we held the Egg-Bot Challenge, a change of pace to give attendees a chance to exercise their graphics skills. The idea of the competition was to use Mathematica to generate designs that could be plotted on spheres…
Above is first place winner Jan Říha’s composition of sinusoidal motifs, and below is second place winner Michael Sollami’s spirograph designs. Head over to see the rest of the entries.
Ann posted instructions in our forums for creating an electric kistka (wax pen) for the Eggbot for traditional Pysanky egg dying techniques. She used nichrome wire, krylon tape, a modified kistka, and a 2xAA battery holder with a switch and described how to mount it in the Eggbot. She posted a couple of designs to Thingiverse demonstrating the technique including the rose design pictured above.
Here’s a little project that we’ve been working towards for a long time: a custom-painted leather flight jacket (“bomber jacket”) featuring the “Classic Lego Space” logo. (Yes, I totally spent years serving in the Lego space corps!) And, if you’ve ever wanted to make your own painted leather jacket — whatever the theme — here’s how to do it.
Ryan Lane posted a couple of short videos of the WaterColorBot drawing a Storm Trooper and Seattle with markers. He traced a photo of the Storm Trooper and applied a half-tone filter before plotting with the WaterColorBot.
