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 Schuyler St. Leger added a vintage telephone bell to his Alpha Clock Five to make an alarm clock that could wake the dead— or at least a teenage boy who’s been watching late night TV.
While talking about egg sizes in the context of the Eggbot project, we realized that while we have access to a few samples, we do not have a good understanding of the normal variation in the sizes of various bird eggs.
The sizes of chicken eggs are well understood and well regulated, but for other types of bird eggs (like the emu egg above) the sizes are not necessarily so standard. If you have access to other types of eggs or eggshells, we’d like your help in gathering data about the size and variation in these other types of eggs.
We’ve set up a survey form to collect egg size data and we plan to post about our results once we have collected enough data.
We’re very pleased to announce some updates on the WaterColorBot project— the watercolor-painting pen plotter that we designed in collaboration with Super-Awesome Sylvia. First and foremost: kits are (finally!) available from stock at our store, now that we’ve finished shipping the rewards from our Kickstarter campaign and our other pre-orders.
We’ve also been working on a host of new applications and accessories that we’ll be writing about in the near future. The first new accessory is the Buddha Board holder pictured above, which indexes a Buddha Board (overly-interactive website link / Amazon.com link), that lets you make temporary paintings with just water. We’ve found the Buddha board not only to be one of the best tools for trying out new things on the ‘bot (without using up paint and paper) but also to be great for live demos of the WaterColorBot, so that you don’t need to provide a fresh sheet of paper for everyone that tries it out. You can find it in our new index of WaterColorBot accessories.
This newly minted (date code: 1403) 555 footstool comes to us via Martin on Twitter, who writes:
My 555 footstools arrived. Build by my father-in-law, based on design files from @EMSL
Here are our original project post and our design. This is the first time that we’ve seen someone else build one based on our design. Nice!
Via @programmer1200 on twitter, “…adding a microswitch and an
@arduino in preparation for a laser addition.” We’ll be keeping our eyes on this WaterColorBot!

From the Lenoir News-Topic, middle school students got to build Egg-Bot derivatives at their local hackerspace:
“I think this is one of the best field trips I’ve ever been on,” one of the sixth-graders said, unprompted by any of the adults (or reporters) in the room. “This one, you actually build something.”
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…
