At SIGGRAPH? Come to our Birds of a Feather Tues Aug 1,10-11 AM

If you are coming to SIGGRAPH in Los Angeles this year, be sure to stop by our Birds of a Feather session:

Best Practices in Making 3D-Printed Math and Science Models

Tuesday, 1 August, 10:00 am - 11:00 am, Los Angeles Convention Center - Room 506
This session is for people who are creating 3D-printed models of math, science, or engineering concepts. Compare tools, techniques, and tips for accurate representations. Bring along a model!
At least "Exhibits Plus" registration is required for Birds of a Feather session. More at

Aug 3-4 (Thurs-Fri) Maker-educator event in West LA!

Maker-educators: awesome two-day event in West Los Angeles. We'll be speaking and exhibiting!  Registration and more info here.

Friday July 14 San Diego: Maker tech to teach science

Three, 3D printed models of surfaces, discretized to varying degrees
Teacher friends in the San Diego area- National University is hosting a workshop about maker tech for science teachers on Friday, July 14.

We have a great lineup!  Rich Cameron and I will be talking about our work creating 3D printed science projects, we'll have two proposed charter schools with a maker focus talking about their plans, case studies from the classroom, an agricultural water-saving Arduino project, and more! Event is free to educators. More:

Hacker Calculus update

Photo of an electronic device, part of which is glowing redWe've added some material to our Hacker Calculus project on Hackaday

Check out the overall project at the link above, or see the directions to build the acceleration sensor shown here in Log #1. It's a great way to start a conversation with students about acceleration, gravity, constant-velocity motion, and more.

Our Hacker Calculus project aims to create a structured set of modules consisting of hands-on 3D printing and electronics projects, with thorough text documentation and minimal supporting algebra. These modules will teach calculus in this hacker style both for self-learners and others, like the visually impaired, who need hands-on learning.

When Isaac Newton developed calculus in the 1600s, he was trying to tie together math and physics in an intuitive, geometrical way. But over time math and physics teaching became heavily weighted toward algebra, and less toward geometrical problem-solving. However, many practicing mathematicians and physicists will get their intuition geometrically first and do the algebra later. We want to let people get to that point directly without passing through (much) algebra, particularly people who learn best by making something.

Follow our project as we continue to add ideas!

Deadline coming 4/23- Scientific Maker exhibit in Hawaii

Share your expertise, creativity, and devices at the American Association for the Advancement of Science (AAAS) Pacific Division’s Second Annual SCIENTIFIC MAKER EXHIBIT at the Pacific Division’s annual meeting, Waimea (on the Big Island of Hawaii) June 19-23, 2017
It is more feasible to create your own lab equipment than ever before with the advent of 3D printing, low-cost Arduino sensors and other “maker” technologies.

It is also possible to have citizen scientist collaborators who cannot only take data for you, but follow open-source plans to create their own equipment. Are you one of the pathfinders that has actually done this? If so, please consider bringing your creation to Waimea on the Big Island of Hawaii for the AAAS Pacific Division’s second Scientific Maker Exhibit. Group exhibits are welcome. Objects that are the subject of work in progress or recent crowdfunding campaigns or equivalent open-source projects are encouraged.

This exhibit area is a “third type” of presentation – not a poster, not a talk, but a chance to show off 3D prints, equipment, etc. There is no provision for hanging a poster at the exhibit – just plan on flat table space and anything you want to put up on a table.

There is no charge for space in this exhibit, but all participants must register for the meeting. Note that display space is limited and acceptance of objects for display will be determined solely by the staff and/or representatives of AAAS, Pacific Division based on quality and scientific merit of the proposed display. Participants take sole responsibility for the safety of their displays, and waivers may be required as detailed in the PDF linked below.

The deadline for submission of an application is 23 April, 2017.

More info about the maker exhibit:…/Flyers/MakerExhibit-Newest.pdf

To apply, fill out the google form at

To apply for a separate poster or oral presentation, to register, or to read about student awards, see the conference's main page at

Hope to see you there!

New book out for preorder

 Our new book (the sixth in collaboration with Rich ("Whosawhatsis) Cameron) is now up for preorder. Some pretty fun models in it!

The cover image is the probability distribution of throwing six-sided dice. The image at the far back is the flat distribution of throwing a one through six with one die. The one in the foreground is what you get when you throw five dice - it approaches a normal distribution.  You can get some very new insights when you have the third dimension to play with!
