WaterColorBot experiments: moss+yogurt and algae+iron paint. With William Jennings.
We’ll be looking forward to seeing followups on these experiments!
In the 1870s, Eadweard Muybridge, using brand new photographic techniques, helped settle a bet about whether horses lifted all their feet off the ground at once. His iconic pictures of horses in motion are frequently used in arts and crafts. (Aside: we even ran into them at Maker Faire in a FlipBooKit animation.)
Amanda found a file on thingiverse of outlines of the Muybridge horses that were intended for use for laser cutting (for animation purposes). She remixed it for use with the Eggbot to make the horses go around the egg and published her Muybridge Carousel design on thingiverse.
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.
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
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.
For a Humpty Dumpty design, she wrote up how she made it:
Using eggbot and custom electric kistka, plotted the Humpty Dumpty picture and text on an egg. First plotted outline, dyed brick, colored in bricks by hand with kistka, dyed blue.
You can check out her other designs for the Eggbot on Thingiverse.
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.
