Thanks to @jumekubo for inspiring my design for a more universal “pocket document camera” that can be affixed to most any device and mirror your hands, drawings, pen marks… #MakerEd #ArtEdTech

I came across a tweet from John Umekubo where he shared a 3D printed design for a pocket document camera that can be used to help a teacher display or record hand motions, sketches, images, or written actions or explanations without needing a second device, an external document camera, or an elaborate setup to balance a camera above your work space! The pocket document camera acts as a sort of periscope to reflect anything being done on top of his keyboard to anyone in his Google Meet. 

John’s post went a bit viral on social media, and he compiled a comprehensive blog post where he listed a bunch of ideas/prototypes created by himself and other like-minded makers. I used our 3D printers in The CoLaboratory (Room 8L in the 610 building) to make two 3D printouts of these pocket document cameras — one that fit my MacBook Air and one that fit the Class III/IV Chromebook. I reached out to our colleagues in the Lower School who are teaching remote pods and told them about this little helper and shared ideas for how it might be used. Joy Barbosa (Class III) asked for a class set, and I printed 13 of these to be sent home to her students. Luckily, materials were already being gathered to send home to the remote Class III learners, and I was able to include this tool in the boxes.

Ju Yeon Kim (Class K) also liked the idea of having her remote Kindergarten students prop their iPad vertically and project whatever they are drawing or manipulating with their hands. Since I didn’t find any existing models for an iPad, It occurred to me that it would be much more helpful to have a universal device-agnostic mirror holder. I used Tinkercad to modify John’s design and created a model which can lay flat against any laptop or tablet (Macbook, Chromebook, iPad) and requires tape, clothespins, or binder clips to affix to the device!

Here’s a link to my most recent design on Thingiverse: https://www.thingiverse.com/thing:4635969

I ordered a bunch of 2″ square mirrors from Amazon (recommended by John in his blog post) and affixed them to the plastic holder with a hot glue gun. Now to make a few dozen more…

Also, here are some mirrors/holders you can purchase:

  1. MirrorMeThis from BrightFingers
  2. iPEVO Mirror-Cam
  3. Hudoo base for iPad
  4. Clip version of Hudoo base for iPad

Making diverse hairstyles and heads of famous people to fit on @LEGO_Group Minifig bodies at the “0 Things” Hackathon facilitated by @DesignMakeTeach. @construct3dconf #construct3d2018 #MakerEd #STEAM

At the first Construct3D conference, Josh Ajima offered a Pecha Kucha talk entitled, 0 Things. Josh “shared his and his students’ experiences of being able to find a multitude of Yoda imagery online, but no 3D models that represented his or his students’ culture or heritage. Josh pointed out that when he searched Thingiverse, a popular 3D printing repository with over 2 million things, he found 0 relevant models for instructional topics. He then challenged the audience to view each empty search as an opportunity, and to use the power of 0 things as inspiration to create powerful, engaging designs and projects.” Here’s a video of Josh’s explaining 0 Things:

At this year’s Construct3D conference, Josh announced a 0 Things Hackathon where attendees gathered to determine searches which yielded no results. Some suggested topics included: Historical figures, Ojibwa Tribe, Monterey Bay wildlife, e-scooter accessories, Jade Museum artifacts (Costa Rica), CS concept manipulations, Virginia peoples, Madres de Plaza de Mayo, female artists, Indus River Valley stamps, “Engineer as Identity”, Women’s issues, Afro centric images, and more.

My first idea for the “0 Things” Hackathon was to create diverse hairstyles and accessories for Minifig heads — braids, dreadlocks, hijab, different curls — so everyone can feel like they’re represented when assembling LEGO figures. I was inspired by an 8th grade student last year. A paper doll outline in the shape of a girl with straight hair was meant to be decorated/personalized by every girl at our school to celebrate our community. This student noticed the lack of diverse hairstyles and quickly made adaptations on her iPad with many options of hair textures and styles to more accurately reflect our population.

A Google search for LEGO Minifig hair confirmed my expectations, and I believe this would be a great project for a class to explore. However, it’s a challenge to draw hair, and we had limited time last night, so my second idea was to gather 3D files of heads of influential figures that could top LEGO Minifig bodies. I located a 3D file of Harriet Tubman’s head and adapted it in Tinkercad, erasing the shoulders, adding a neck column, and inserting a hole at the base that should fit upon the neck peg of a LEGO Minifig torso. My published adaptation is here:

Thanks to @wagongrrl @openblackboard @gravescolleen @morrill_rob (and others!) for sharing 3D designs for coin cell battery holders! #MakerEd #STEAM #STEMed

Thanks to the generous makers below for designing and sharing these helpful 3D templates that hold a coin cell battery in place while allowing wires, conductive thread, and/or copper tape to conduct electricity:

What’s in the box from @FredBartels @Kickstarter project?

Six months ago, I back Fred Bartels Kickstarter project to develop a 21st Century Open-Source Building Toy. I have a ton of respect for Fred, and I was curious about his attempt to encourage people to “Let Go of Your Lego.” The parts combine to be a Tin Toy — TIN being an acronym for Triangulated Irregular Network Toy.

My package arrived this morning, and I realize that the building possibilities are endless…with enough pieces. Here are some helpful links:
