Prototyping a wall mount for alligator clips to hang in the @BrearleyNYC #CoLab. #MakerEd @ultimaker @thingiverse @tinkercad

In the CoLaboratory, we have a large bin marked ALLIGATOR CLIPS that was becoming a bit of an organizational nightmare with 5th graders struggling to free a wire from a tangle of metal-tipped tumbleweeds. I figured a wall-mounted solution might be helpful, and I asked my 5th graders for their opinions and suggestions.

My first physical prototype was a scrap of cardboard affixed to the side of a shelving unit with a large binder clip. Then, I mocked up a simple comb-inspired design with Tinkercad and later added perpendicular bits to the edges of the tines (like a rake) to keep the wires from slipping out. I belatedly noticed we have alligator clips of different thicknesses, so I also made another version with wider spaces between the tines.

I couldn’t find a satisfactory wall mount for a mini glue gun, so I made one with @Tinkercad and an @Ultimaker. You can find it on the @thingiverse… @BrearleyNYC #MakerEd #STEAM

Problem Finding begat Problem Solving!

It troubled me that students would plop the glue gun on the counter top in between squirts, leaking glue and causing a burn/fire hazard. After searching for a wall-mounted solution, I ended up making my own design in @Tinkercad and printing on one of our @Ultimaker printers.

After several incarnations (and a small pile of plastic), I settled on a relatively simple model that will hold a mini glue gun against the wall during use or while cooling. I posted my design to @Thingiverse here: https://www.thingiverse.com/thing:5377878

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

Notes from @STEMteachersNYC’s “Design, Engineering, and Maker Cultures” workshop at @CUSEAS this week. #MakerEd #STEAM #STEMed

IMG_4934

I attended Design, Engineering and Maker Cultures this week which was hosted at Columbia University’s School of Engineering, organized by STEMteachersNYC, and led by Michael Katz and Frances Hidalgo (two volunteer teachers from the STEMteachersNYC community).

Here is the workshop’s description as per their registration page:

Interested in learning more about the engineering and design process, and how to incorporate it into your classroom? This workshop is designed to show how you can infuse engineering and design thinking into your curriculum. Drawing from the NGSS Engineering Design standards we’ll explore how students can use design and affordable makerspace technologies to ask questions and define problems; to formulate, refine, and evaluate testable questions; and design problems using models and simulations.

Throughout the workshop, participants will explore easy-to-deploy design experiences for a range of grade levels. Participants will have the chance to experience several hands-on projects like making paper circuits, while also troubleshooting strategies for setting up a Makerspace in your school and using this as a platform for curricular integration and development. Attendees will also spend time identifying areas within their curriculum that naturally lead to incorporating more creativity, innovation and collaboration. So whether you teach elementary or high school students, come learn and experience how fun and easy it can be to incorporate engineering and design in your classroom.

This was the first time this workshop has ever been offered, and I imagine the next manifestation might have less pre-activity lead-up discussions and more time for hands-on learning, group activities, and collaborative lesson brainstorming.  Here are some of my highlights from the three days:

    1. I loved meeting awesome educators from public and private schools who all have a shared interest in expanding their skillset, innovating, and sharing ideas.
    2. I worked with a group to build a prototype of a machine inspired by nature. Biomimicry is defined by the Biomimicry Institute as “an approach to innovation that seeks sustainable solutions to human challenges by emulating nature’s time-tested patterns and strategies.” My team considered how the blue whale’s baleen might inspire an amphibious coastal Roomba-like cleaning mechanism. Our design, Blue Whale Blue Crab (or Beach Clean Baleen) also included crab-influenced claws. Ideally, this amphibious machine will travel on land and sea, filtering inorganic material and sorting it into onboard containers. Metal could be further sorted by using a magnet on the claw and a more powerful magnet onboard near the sorting bins. I was really happy with our teamwork and proud of our protoype!
    3. Gail Sestito (aka @TheRobotFairy) totally blew my mind when she shared how a student of hers demonstrated how to merge two words into a fascinating mathematical parametric 3D shape using Onshape. She then took this idea and collaborated with an English teacher for a project that physically illustrates the concept of Doublespeak from George Orwell’s 1984. For example, they made word sculptures where one view of the piece reads Truth and one view reads Lies. Or War/Peace. Or Love/Turture. Such a great project!

      Here is Gail’s awesome merging of her name and my name!

    4. Bill Miller is the Makerspace manager, and he showed us two fascinating innovation centers. First we went on a tour of the Department of Mechanical Engineering’s extensive fabrication spaces. After, Bill showed us where the new community Makerspace will be — it is transitioning from a decent sized room on the 12th floor (which I visited many moons ago) to a huge facility on the 2nd floor. The budget to revamp and outfit this newer facility was $400,000!. 💰😳 Here are some photos:

After seeing their bank of Ultimaker 3D printers, I offered to connect Bill to @LizArum, Ultimaker’s Community Manager and an incredibly knowledgeable, generous, and brilliant friend. Yay for connecting people who may end up further collaborating in some capacity! Here are two upcoming and worthwhile events Liz is organizing:
