We’re big fans of Voronoi diagrams, and use them in StippleGen so it’s awesome to see them in 3D printed pumpkins this Halloween season. Voronoi Pumpkin #1 shown above is available through Shapeways, along with the equally creatively named Voronoi Pumpkin #2. There’s also a Voronoi Jack-o-Lantern on Ponoko, and more even more Voronoi Pumpkins on Thingiverse.
We just got an advance copy of The Art of Tinkering, by our friends at the Tinkering Studio at the Exploratorium.
On their own, science, art, and technology all make for interesting, fun, and rewarding explorations. But when you mix them together, you get a veritable tinkering trifecta in which technological tools and scientific principles let you express your own artistic vision.
We flipped through the wonderful pictures and projects before we took it to the bench for some quick pictures. In the spirit of the book, we put it among a few tools and parts from recently photographed projects that were still on the table.
We found projects by some of our friends, including Ken Murphy, Jie Qi and AnnMarie Thomas. We’re excited that we have a few projects in the book, including our Circuitry Snacks, in a section on Surprising Circuits. The book itself incorporates some circuitry on the cover, which we hope to play with soon!
The book launch party will be at the Exploratorium Afterdark (ages 18+) event on November 7.
BarBot, the premier cocktail robotics event, is this weekend, October 25-26 at the Odd Fellows Hall in San Francisco. Tickets are on sale now (ages 21+ only).
We’ll be bringing Drink Making Unit 2.1, with its new vodka switch and peristaltic pump.
Peter wrote in to share his build based on our Tennis for Two video game project.
He has more pictures up in his post.
For Lady Ada Lovelace Day, we are once again celebrating women in open source hardware. Pictured above are three key women from the 2013 Open Hardware Summit: Catarina Mota, from the Open Source Business panel and OSHWA board member; Addie Wagenknecht, Open Hardware Summit co-Chair; and Alicia Gibb, conference organizer and OSHWA president.
A number of women also presented talks during the summit:
In addition, the following women presented posters or demos:
Toni Klopfenstein, Erin “RobotGrrl” Kennedy, Gabriella Levine, Analisa Russo, Amelia Marzec, Anuja Apte, Nadya Peek, Tania Morimoto, Ayah Bdeir, Linda Karina Duran Bautista, Aisen Caro Chacin, Pilar Zaragoza, Alexandra Shuey, Christalee Bieber.
All of these presenters build on a history of excellent content within this vibrant community.

Just in time for Halloween, we’re launching a Snap-O-Lantern kit. You can still build this robotic snapping pumpkin from scratch using our original instructions, or you can do it the easy way with this kit, which uses one of our ATtiny2313 target boards and has all the parts you’ll need— except the mini-pumpkin and three AA batteries.
We’re putting the full documentation for the kit on our wiki.
Pumpkins are being featured today on a special Halloween edition of Maker Camp, and I’ll be there, showing our Snap-O-Lantern project. Tune in at 5 pm (Pacific), today, Thursday, October 10.
Dan at Maniacal Labs posted a review of our Three Fives kit:
… yay for creative kits that cause you to go out and (re)learn stuff! The cool thing about the 555 chip is that it is very much a building block to bigger things. There are plenty of resources out there for 555 applications and project ideas. I’d like to thank Eric Schlaepfer for his awesome kit idea and Evil Mad Scientist for helping make it available to the masses!
dinofizz posted in the forums about the LED display based on the Peggy 2 he installed on his vertical blinds:
I had custom PCBs made to help daisy chain the vertical blinds (they’re sitting on top of the horizontal beam from which the blinds hang). 300 ft spool of 16-way ribbon cable completely used up. Around ~4000 individual solder joints, and I’m still using breadboard to hold things together at the moment! Took me forever.
He linked to a few more build photos over in the forum post, and he even posted some video of it in action:
One of the treats at Maker Faire New York was watching kids playing Michael Newman‘s mechanical Video Sans-Video Game. The play field is a scroll of paper with drawn-on caves and channels through which you must navigate (via joy-stick) your little paper space craft on an X-Y stage. If your craft collides with a wall or an asteroid, an infrared detector sees the darkened part of the paper, and it is game over!
Michael brought two versions— a large arcade style one with a belt driven stage, and a smaller one modeled after the WaterColorBot cord and windlass system.
One interesting thing about the young kids playing the game is that none of them had ever seen a media system that required rewinding to restart. Michael drew a new game Sunday morning to replace the slightly tattered roll after a full day of play at Maker Faire on Saturday.
