5 Fun BBC Microbit Project Lessons

As I have reflected on various physical computing activities we tried with our kids, I started reviewing a novel microcontroller from our friends at the BBC, the micro:bit.   In addition to the BBC bringing us awesome stories like Dr. Who, this organization has invested their resources to help students connect to creative computing tools for young makers.   The BBC micro:bit continues this cool tradition by offering inexpensive microcontrollers to empower students to build robots, explore wearable computing, and invent new stuff.  The BBC micro:bit device has an amazing set of features: Bluetooth or radio communication, a compass sensor, shake sensor, a couple of push buttons, a grid of LED lights, compact battery pack and a good number of inputs and outputs.   The input/outputs enable the student to drive servos, drive speakers or connect to other electronics.  I love this platform since novice makers can program the microcontrollers with block programming.  Advanced students will enjoy the ability to program the microcontrollers with languages like JavaScript and Python.  That’s a lot of capability for a low-cost microcontroller under $30.  I believe the BBC micro:bit can be a fine alternative to an Arduino for beginners.

Thank you to LucernaStudios.com and Orlando Unity 3D meetup!

Published on February 10, 2018 by in technology

In the past week, our Google Developer Group of Central Florida teamed up with the Unity 3D meetup of Orlando and LucernaStudios.com to discuss building VR experiences for Google VR.  We shared the fundamentals of building for Google DayDream and Cardboard.   We also explored connecting those game experiences with Google Firebase.

I want to give a shout out to Hunter and Jose from LucernaStudios.com.   Longtime readers of InspiredToEducate.NET know that we believe in playful learning.  (game-based learning or challenge-based learning.)   LucernaStudios.com care about helping kids to learn through engaging game-based learning.   I also appreciate their vision to connect families through game-based learning.   We appreciate them coming out to our meetup to share their story with building a math education game using Google Cardboard SDK.   Beyond that, they also talked about their lessons learned in playtesting their games, exploring the educational technology market and focusing on knowing their audience.  I like the way they’re applying lean startup ideas.

Lucerna at GDG / Unity 3D meetup.

To the Unity 3D meetup group, we appreciate your community and quality content that you organize regularly.   If you’re interested in connecting with other game developers or people interested in VR/AR, you’ll enjoy this community.   You can connect with the Orlando Unity 3D meetup at their meetup page.

To help provide a project-based learning experience around Google VR, our Google developer group drafted a small multi-player block builder experience we call “Block party.”   It provided a solid set of examples to talk about Firebase real-time database, DayDream instant preview, and other Unity 3D fundamentals.

Block Party VR

Block Party VR provides an open source project based learning experience for developers getting started in VR or gaming. In this proof of concept game, we will build a multiplayer “Minecraft” like experience designed for VR. The current implementation leverages Google Firebase for client collaboration.

To maximize the impact of the project, we will focus on building a Google Cardboard app in the beginning.   Google Cardboard VR has the largest VR market share.  The platform can support iOS and Android devices.

https://vr.google.com/cardboard/

We are open to seeing Block Party VR ported to other VR and AR platforms.   While the current implementation leverages Google Firebase, it would be cool to learn other multi-play platforms too.

Check out the following link to get started.

Where is the source code?

All code for block party is released under MIT public license.

What’s new in Google Virtual Reality?

Published on January 13, 2018 by in technology

DayDream

Google DayDream and Google Cardboard seek to make virtual reality experiences broadly accessible leveraging your smartphone and cleverly designed viewers. The initial release of Google Cardboard had a great DIY feel. Developers received a laser cut cardboard structure that you fold into a viewer, lenses, and a magnetic button. Using the sensors on your phone, Google Cardboard applications enable you to direct your view of the virtual world. Since the initial release of Google Cardboard in 2014, Google and their partners have launched an impressive ecosystem of VR applications and headsets. Check out the full history of Google cardboard here.  Today, you can purchase a comfortable Google Cardboard compatible headset from your local toy store, Walmart, or Target at a low cost. It should be noted that Google Cardboard works on Android and iOS.

Building on the experience of Cardboard, Google designed DayDream as a first class VR experience that includes a motion controller. You can think of the motion controller as a “Wii remote” for VR. The elegant design enables you to point and click on elements of your VR world. With the motion controller, users can explore and interact with VR worlds more robustly. You’ll find apps that let you move around a VR space. Click and scrolling through content is much easier using the controller. Unfortunately, the Google DayDream system requires a high performance device like a Google Pixel or Samsung S8. In the coming years, you will see Google release stand-alone Google Daydream headsets that provide the Google DayDream experience, but does not require a smart phone. During the CES conference this week, we got our first glimpse at the first Google DayDream headset by Lenovo priced around $400.

Cool experiences using Google VR

360 Videos on YouTube: For parents and educators, you’ll find YouTube 360 a useful tool for student engagement. Let’s say you’re introducing students to the internals of cells in Biology. You can find 360 videos of cell structure by searching in YouTube. Just include ‘360’ in your search. If a video supports a VR mode of exploration, you simply press the Google Cardboard icon and place your phone into your headset. This feature should exist on Android and iOS. In recent years, major newspapers have started publishing VR experiences to complement news stories. (Washington Post, Discovery, PBS, CNN, etc.)

360 Photos: Over the years, I have started to collect 360 photos of various places on our family trips. Using applications like Google Cardboard camera, it’s easy to take panorama photos and explore them later in VR. This feature should exist on Android and iOS.

Google Street View: I still think it’s crazy and amazing how much of the world has been indexed using Google Street view. Let’s say you want to give your students a tour of Kennedy Space Center in Florida. You can find it on Google street view. On Google DayDream headsets using the Google Street view app, you can tour all snap shots captured in Google Street view. And there’s a lot of them! My kids recently learned that the island in the “Last Jedi” where Rey and Luke meet actually exists in Skellig Michael in Ireland. You can tour this island using Google Street view in Google Daydream!

Arts and culture: Google Daydream has an awesome application for touring museums worldwide entitled “Arts and Culture.” It’s a delightful way to sample great collections of art from the comfort of your device.

Google expeditions: Many at Google have seen the potential of using the engagement factor of VR to inspire curiosity and exploration with their students. To help teachers facilitate “VR field trips” for their classrooms, Google has launched a program and app known as Google expeditions. In the original design of this application, the teacher has a central app for loading different VR scenes and experiences. The control center influences VR headsets used by students in the classroom. Many of these experiences are carefully crafted in collaboration with educators for effective teaching and learning. The collection of VR experiences indexed in this app is amazing. It’s worth checking out. As the class navigate through their “VR field trip”, the teacher can guide and lecture to help focus the students on various parts of their shared experience. In a more recent release of Google expeditions, you can now tour Google expeditions without a teacher guide. To learn more about Google Expeditions, check out the following talk from Google I/O 2017. I really love this application of VR.

In future posts, we will share resources for building Google cardboard and DayDream experiences.

Adventures with Star Wars: Last Jedi AR Stickers

Like many families, we had the opportunity to check out the latest Star Wars movie, the Last Jedi. It seems that Google’s AR team and Disney have cooked up a fun Christmas gift for owners of Google Pixel phones: AR Stickers. We’ve seen sticker augmentations in other photo apps like Snap Chat or Facebook messenger. The AR Stickers feature in Google’s photo app enables you to place 3D content in the context of your environment. Using very advanced surface detection, location, and mapping tech called AR Core, the AR stickers feature does a quick scan of your environment to find surfaces. You can then place Star Wars stickers in your world. The localization and mapping tech has greatly improved.  While it has a few imperfections, it’s still crazy fun to enjoy with your family and friends. Here’s a few pictures my family and I cooked up today. For a good laugh, you should check out the hashtag #arstickers for other Star Wars fan building Star Wars scenes in their homes and public spaces. I can’t wait to see this idea expand broadly to other platforms. This is fun disruption to taking photos and videos. 🙂

Connecting Community Service to Makerspaces and Developer Communities

Team Open Barter

In November 2017, I had the honor of speaking at DevFest Florida, a community organized developer conference focusing on Google technology. I had an amazing time at this conference. You can check out my reflections on this experience at GDGCentralFlorida.org. Readers of InspiredToEducate.NET know that we’re passionate about helping students to love learning through making, tinkering, and engineering. For me, I encountered a talk that impacted me regarding the intersection of community service and maker education. I do believe in Daniel Pink‘s argument that we’re very motivated or driven in situations where we have autonomy,  are growing in mastery, and acting with purpose. The projects that I’ll discuss in this post connect strongly to mastery and purpose motivations. This talk encouraged me to reflect on why I enjoy helping people to learn to code and the culture of a maker space.

Etienne Caron-Petit-Pas shared an amazing story of using mixed reality and maker technologies to create a positive social impact in this community. In OSMOS academy that he helps organize, I appreciated that their community focuses on building stuff that can help enrich people’s lives. It’s not just about the maker tech. For example, their current project focused on building playful VR experiences to support and distract kids who are going through medical procedures in a hospital. Some of the other projects they have attempted feel like citizen science efforts. This talk touches technology ranging from Google Daydream, augmented reality, Android Things and more.

In general, we’ve explored the idea that maker education connects students to the experience of project based learning. Under this paradigm, students engage in learning through the construction of projects or physical stuff. Learning is not centered around a teacher as the center of knowledge. Maker education learning experience always ask students to personalize the learning experience by asking the student: what do you want to make? All other lessons connect into project direction set by the student.

Along a similar theme, I recently encountered a cool podcast interviewing the founder of FreeCodeCamp.com, Quincy Larson. Quincy Larson worked in a traditional k-12 school working as a teacher. Along the way, he became interested in giving his fellow teachers more time by automating administrative computer tasks and creating systems for automatic grading. Through this experience, he became interested in learning to program professionally. After connecting with local makerspaces/hackathons, local meetups, and doing thousand of hours of study of MOOCs, he returned to his “teacher hat” and realized that many others might want to go on this journey too. He helped organize FreeCodeCamp.com to help other “campers” leverage resources and coaching he had gained. I’m very impressed with the scale of curriculum, community and effort to create local meetups in cities near you. While it’s easy to find YouTube videos or Mooc content to learn stuff, their teaching team acknowledges that learning as a local tribe in your local coffee shop or makerspace really helps to drive the learning forward. It’s very easy to get demotivated when you don’t have mentors or fellow students to go on the journey with you.

I do want to give a shout out to “The Change Log” podcast that shared this conversation.  I haven’t been listening to them long, but I enjoy their content.
https://changelog.com/podcast/195

FreeCodeCamp.com connects with the idea of community service learning by engaging real non-profits with real IT needs with their students. It’s a really neat “win-win” situation. The non-profit gets a cost effective solution. The students have a great learning experience addressing a local need while growing their web development skills.

On a personal level, I have enjoyed seeing students(young and old) become engaged with their path of learning through hackathons, makerspaces, and developer community. Why does community service learning matter? This feels like a unique flavor of project based learning since grass root connected learners work together to learn while making a difference in their community. The world needs more of this kind of innovation in education and community service.

Bot Draw : Logo like framework for building VR experiences

Sample AFrame experience

Welcome to Bot Draw!(aka Project Dark Bat)

Looking for a fun way to practice your JavaScript skills and build cool VR experiences? InspiredToEducate.NET designed this code sample to enable you to play with very simple ideas in JavaScript. This sample uses a JavaScript framework called AFrame to build 3D content in your browser or mobile phone browser. The display engine supports major VR platforms including Google Cardboard, Vive, and Oculus. (Thank you AFrame community!)

In Bot Draw, you command a small bot who can travel in 3D space. The robot can place boxes, spheres, images, and other 3D shapes. This tool borrows ideas from popular code education tools like Logo, code.org, ScriptCraft by Walter Higgins.

You can review a sample scene here: https://dark-bat.glitch.me/

You can use the keys WASD to move around the scene.

You can edit and study the code here: https://glitch.com/edit/#!/dark-bat

If you make something cool, please let us know!

Hope you find this fun and helpful!

 

File Overview

  • views/index.html – This file contains HTML and JavaScript for the VR scene. To learn more about AFrame related content, please refer to AFrame.IO. Feel free to remix this glitch sample and start tinkering!!
  • public/demo.js – This file provides other demo functions using bot draw.
  • public/bot_aframe – Interested in enhancing the “Bot” code? This is the file for you!

Bot Draw methods

In order to draw, you start by creating an instance of the bot. The bot object has additional methods for drawing, turning, or moving.

Moving and turning:

  • moveUp(steps) – Move the bot upward a few steps
  • forward(steps) – Move bot forward a few steps
  • moveLeft(steps) – Move bot left
  • moveRight(steps) – Move bot right
  • setAngle(degrees) – Set angle of direction for the robot. Enter direction in degrees
  • getAngle() – Get current angle for the robot.
  • turn(angle) – Turn the robot a few degrees.

Drawing stuff:

  • drawBoxAt(width,height,depth,x,y,z) – Draw box at a particular location.
  • drawBox(width,height,depth) – Draw box at current robot location.
  • drawSphere(radius) – Draw sphere at current robot location.
  • drawSphereAt(radius,x,y,z) – Draw sphere at particular location
  • drawCone(radius,height)
  • drawCylinder(radius,height)
  • drawImageAt(strPath,width, height, x,y,z) – Draw image at particular location. The path should be a fully qualified path to a valid web image.
  • drawImage(strPath,width,height) – Draw image at bot location. The path should be a fully qualified path to a valid web image.

Remember locations, Return to locations

AFrame: Building WebVR experiences with HTML and JavaScript

Sample AFrame experience

Hey, makers and web developers! Looking for a fun weekend coding challenge? In this post, I wanted to introduce you to a simple tool called A-Frame for building VR experiences using HTML and JavaScript.  Originally sponsored by the Mozilla foundation, A-frame enables you to quickly build WebVR scenes, panoramas, games, or data visualizations.  With very basic HTML skills, you can build delightful VR experiences.  I believe you’ll find the declarative or tag based coding style very approachable.  For advanced developers, you can drop to the JavaScript and ThreeJS abstraction layers to customize the experiences in more detail.

Don’t have an expensive VR rig? No problem!  AFrame supports platforms as simple as desktops, mobile phones or Google Cardboard.  I find it impressive that the AFrame platform supports advanced rigs like Vive and Rift.    I’m looking forward to seeing support for Microsoft Mixed Reality too.

Here’s a quick “hello world” experience for you to test drive.

Projects Built with AFrame

How can you get started with AFrame today?

Make sure to check out the impressive community of plugins on the AFrame registry
