Gathering my tweets from the 3rd @construct3dconf hosted at @RiceUniversity this week. #Construct3D #MakerEd #ArtEdTech

Construct3D is a great conference! I’ve been to all three events, and the quality of the keynotes, posters, attendees passion, interesting conversations, networking (and food) is always awesome. I always learn a ton and I leave inspired and truly energized (albeit momentarily exhausted). Per their website’s About page:

Construct3D is a vendor agnostic 3D printing, digital fabrication conference and expo focused on academic use, best practices, and professional development opportunities for faculty, staff, and students from informal, K12 and higher ed contexts. Construct3D is where passionate and curious educators and innovators converge to exchange ideas, build networks, learn new skills, and accelerate the adoption and exploration of 3D printing in education.

Below, I’ve gathered my tweets so that I can refer back to them without having to scroll through my Twitter timeline:

I also gathered photos I took during the conference (however limited and haphazard they ended up being) here:

Gathering my tweets, photos, and notes from #Picademy in Jersey City. Thank you, @Raspberry_Pi for two days of inspiring, exciting, fun, and thought-provoking professional development! #STEMed #STEAM #MakerEd

I felt incredibly fortunate to be in a room of educators on June 21-22 for two days of Picademy hosted at the Liberty Science Center in Jersey City, New Jersey! The workshops were led by Andrew Collins (Educator Training Manager at ) and Raspberry Certified Teachers from previous co-horts (Amanda HaughsChantell Mason, and ). There was a separate Picademy June 18-19 and other networking opportunities throughout the week facilitated by Dana Augustin (Educator Program Coordinator at ). Per Picademy’s website:

Picademy is the Raspberry Pi Foundation’s free face-to-face professional development programme that supports educators throughout their digital making and computing journey. This two-day training event is held at venues around the UK and North America. After completing the programme, educators join a community of passionate digital making practitioners.Interested in attending? Visit our event calendar to find a Picademy near you.

Day 1 consisted of a crash course in setting up the Raspberry Pi (HDMI to a screen, USB to keyboard and mouse, power cord, SD card) and gaining insights into a variety of attachments and HATs (GPIO boards, Sense Hat, Explorer Hat Pro, Piano Hat, Mini Black Hat Hack3r, Camera Module V2, Traffic Light add on).

Day 2 was an opportunity to break into groups and have extended time to develop a project prototype. I partnered with Cathy Knives Chau and Lauren Berrios, and we created PiPix, a portable RaspberryPi powered Polaroid-inspired camera that can be picked up by students at any time to take pictures of class projects or on class trips. Different filters can be applied, and photos would be uploaded to a class Twitter stream. We successfully designed a countdown timer to display on the SenseHat, enabled the SenseHat’s joystick to take the picture, and had a random filter applied to the captured image. We needed more time to have the joystick be used to choose a filter and/or allow the user to choose to capture an image or an animated GIF. We were on the verge of integrating our program with Twitter’s API (Thanks to Cathy!), but didn’t manage this in time. Cathy, Lauren, and I are hoping to gather later in the summer to complete a successful PiPix prototype!

Here’s our code so far…

Making cardboard, #FunkeyFunkey, and @Scratch slot machines starring @brearleynyc’s class mascots for our upcoming Casino Night. #MakerEd #STEAM

Before Thursday’s Upper School performance of Guys and Dolls at The Brearley School, there will be a Supper Club Casino Night for the community with games led by faculty. I offered to help, though I was worried about being responsible for learning and facilitating Poker or Blackjack, so I offered to make some slot machines.

I figured there must be a bunch of programs shared by the awesome Scratch-user community, and they didn’t disappoint. I remixed this project generously offered by Jcg127: https://scratch.mit.edu/projects/23156262/#player

I removed the Yay! and Jackpot! procedures and swapped in nine new costumes representing Brearley’s class mascots (camel, penguin, tiger, owl, duck, buffalo, elephant, bear) and the official school mascot (beaver).  I then found some cardboard in the recycle bin and built some quick yet sturdy casings for three separate laptops.

I knew I’d use some of our FunkeyFunkey boards for the project and was originally considering a physical lever with a tilt sensor. I imagined having a hinge or printing 3D pieces (similar to Makedo parts) to hold a long cardboard tube in place (I have a stockpile of cardboard tubes from wrapping paper rolls). A rubber-band stretched somewhere would allow the lever to pull forward yet return upright for its home position, and the tilt sensor inside the tube would recognize when the arm was lowered and “spin” the rollers in my slot machine.

However, I had four hours today to generate the Scratch program and mock up the cardboard cases, so I used our FunkeyFunkey arcade buttons instead. They are build like a nut and bolt, and they sandwich cardboard beautifully. Easy peasy! Also, Stephen Lewis (creator of the FunkeyFunkey) designed his sensors (tilt, touch, button, infrared, etc.) to work even without being grounded, so they are so much easier to incorporate into projects.

If I had more time, I’d definitely make my slot machines more attractive. These definitely look homemade. 🙂 Here’s a tutorial for a DIY slot machine I belatedly found: http://www.instructables.com/id/HOW-TO-MAKE-SLOT-MACHINE-DIY/
