2011 was a Great Year for Harris Educational

2011 was a fairly trying year for the world as a whole with man-made problems of economic turmoil and political strife, as well as natural disasters and bad weather. But in spite of the environment Harris Educational had a wonderful year in 2011. I’m attributing this to hard work and dumb luck on our part but I know the biggest reason for our success was due to our readers, our fans, our customers, the good folks at ShopBot, Make Magazine, and all the wonderful resellers of our Reinventing Science kits.

Our year started out with an upgrade to our science kit production capabilities in the form of a new CNC Router. Our goal was to automate the production of some of the parts of our Reinventing Science kits and also to allow for new product development of parts that would not be easy to achieve using other more traditional methods. To learn how to use the new router my first project was to build a custom computer case and a new computer that we could use to edit and produce more video. The Ingenematic Visitron was born and I’m proud to say that the story was picked up by Hack-a-day sending quite a few visitors to our blog and making us a few new fans.

2011 saw my first trip to Maker Faire in California. In May my nephew Brian and I traveled to California to exhibit the Reinventing Science kits to throngs of people at the Maker Shed inside Maker Faire. We met a lot of interesting people, made some new friends, and caught the attention of Popular Mechanics who mentioned Harris Educational and the Reinventing Edison kit by name as one of the reasons that the Maker Shed was one of the top ten coolest things to do at Maker Faire! (TONS of photos from Maker Faire are on our fan page here, here, here, and don’t forget the video we posted “The Motion of Maker Faire” below)

One of the big events at Maker Faire in California was the Hackerspace Challenge, and I met a lot of interesting people from different maker spaces from around the country. On my flight back to North Carolina I kept thinking how great it would be to have such a place here in my home town of Burlington. I started brainstorming for ways to make this happen by expanding Harris Educational (a project I’m still working on)

In June my nephew Brian helped me again and we exhibited Harris Educational and the Reinventing Science kits at Maker Faire NC in Raleigh. (Tons of Photographs Here, Here, and Here) Maker Faire NC was in its second year and it was great to meet and become involved with all of the folks responsible for making this faire a reality. Two other great things came out of this mini maker faire. Thanks to a sign in our booth asking Alamance County people to say hey to us I met a couple of folks who have become founding members of our new Alamance Makers Guild. The second thing to come out of MFNC is our new relationship with ShopBot tools of Durham NC. Harris Educational is now working with ShopBot to create STEM based curriculum materials around Digital Fabrication technologies such as their CNC Routers. The second half of our year has seen quite a bit of development on this project, not to mention the addition of a ShopBot desktop CNC Router to our list of tools.

In July and August more people learned about Harris Educational thanks to some local news stories. The first was a full page article written about us in the Burlington Newspaper, “The Times News.” This story then got the attention of WGHP Fox 8 news out of Greensboro NC who interviewed me for the evening news segment “Made in NC” You can see the video above.

In August I set up a “Meeting of the NC Makers” including the folks from ShopBot Tools, Roy Underhill from PBS’s Longest Running DIY Show “The Woodwright’s Shop”, the folks from Maker Faire NC, and some others for a fun day of woodworking in high tech and in historical contexts. In the morning Roy Underhill visited ShopBot tools to see CNC Routers in action, and after a great lunch at Ted Hall’s house in Durham, everyone visited Roy Underhill’s Woodworking School in Pittsboro NC. While there I shot put together the following videos.

With support from the folks I met at Maker Faire NC I’ve officially launched “The Alamance Makers Guild” through a group, a fan page on facebook, and a twitter feed. We’re now holding regular monthly meetings and members have shared their talents and their creations including some really cool wood turnings, steam punk art pieces, and even a home made tesla coil! Much more with the Alamance Makers guild in 2012.

This year also saw our first international sale of Reinventing Science kits with the addition of a new reseller in the Republic of Korea.  The year also saw the addition of Pasco Scientific as a dealer, and Educational Innovations adding our Reinventing Morse kit.  We’ve also laid some groundwork for the setup of some more new resellers for 2012. Sales for the kits continue to increase, a great accomplishment for such a flat economy.

The year finished out with some very positive recognition of our Reinventing Science kits! The Surprising Science blog at the Smithsonian picked our Reinventing Edison: Build your own Light Bulb science kit as one of the top 10 best gifts for Science lovers. We were also highly honored to have been picked by Make Magazine as one of 12 Science Kits reviewed in their “Ultimate Kit Guide” special edition. We received a 5 out of 5 for the quality of our instructions and our materials! I was also very happy to read all of the comments about the kit when they gave one away at their blog.

2011 was a great year for Harris Educational and I’m sure 2012 will bring all new challenges and opportunities.  Thanks to everyone who supports us!



Harris Educational and Reinventing Science Kits in the News!

Thanks to my involvement with Maker Faire, my efforts in Social Media, and some other projects I am starting to get a little attention from the local news media for Harris Educational and the Reinventing Science kits.

On July 10th I was featured in a full page article in the “Accent” section of the Sunday edition of “The Times News” here in Burlington NC. The article “A Science Hobby becomes a career” by reporter Molly McGowan tells some of the story behind how and why I started Harris Educational and how I make the Reinventing Science kits here in Burlington (proudly hand made in the USA!). The article is online and can be found at the Times News website HERE.

That article lead to an interview with Brad Jones of WGHP Fox 8 News (of Greensboro NC) for their “Made in NC” segment. “Made in NC” features new, innovative, and interesting companies in North Carolina that make products here in NC. It was an honor to be included in this segment and I’m glad to be able to get the word out about what I’m doing. I’m very happy at how the interview turned out and feel it was a good mix of my philosophy behind Reinventing Science kits, a look at the kits themselves in action, and some good footage of me making parts for the kits. They even managed to get some focus for my new ShopBot Desktop CNC router.

The interview aired on the evening news on August 26th. I’ve uploaded my off-air recording of the interview to YouTube (see above) but a higher quality version can be found at the Fox 8 “Made in NC” site HERE (along with links to all of the other interesting companies and products they’ve featured).

They say everyone gets fifteen minutes of fame. By my calculations I’ve now used up about three of mine. I wonder where my adventures with Harris Educational, Maker Faire, ShopBot, and my other projects will lead me next? Its always great to make more people aware of the kits and help improve sales a little, but really I’ll be happiest if these stories (and hopefully future ones) lead to more fans for the community I’ve been developing on Facebook on the Harris Educational fan page.

Announcing a New Partnership between Harris Educational and ShopBot Tools

It is with great pleasure that I announce a new partnership between Harris Educational and ShopBot tools of Durham NC. I will be applying my skills and experience in instructional design, educational development, and K-12 science and technology education to help ShopBot create a unified, modular STEM curriculum about Digital Fabrication related to their popular and successful CNC routers and other tools.

ShopBot Desktop CNC Router Digital Fabrication Tool

The New ShopBot Desktop CNC Router Digital Fabrication Tool

ShopBot Tools of Durham NC designs, manufactures, and supplies digital fabrication tools such as 2D/3D CNC Routers, 5-axis CNC routers, and related equipment. They are committed to making these tools at a very high quality but also at a very affordable price. I’ve met the folks from ShopBot, toured their facilities, sat in on some of their training, and observed them at two Maker Faires and I can tell you they are a different kind of company! I’ve found them to be very open and very forward thinking. Every employee is enthusiastic and committed to what they are doing. As one of their motto’s says, they build the tools for building the future!

Digital Fabrication covers a wide range of technologies that have evolved from expensive specialized industrial machines and processes to affordable and flexible solutions that are now well within the reach of individuals, students, schools, and small businesses. These tools and techniques allow a person to go from a digital design created on a computer and translate that it into a real working physical object.

Digital Fabrication tools can be subtractive (like CNC routers, milling machines, or laser cutters) or additive (like plastic extruders and deposition printers) or even a combination of the two. Just as the PC and then the Internet have revolutionized how we create and share information digital fabrication technologies are revolutionizing how we create and distribute physical objects and products. To translate an idea into reality in the past would have require a workshop full of tools as well as a great deal of experience, skill, and patience. These new tools such as ShopBot’s CNC machines free anyone to focus on design while the machine does the work.

Maintaining our leadership in research and technology is crucial to America’s success. But if we want to win the future—if we want innovation to produce jobs in America… then we also have to win the race to educate our kids.”              … President Obama (State of the Union Address, January 2011)

STEM stands for “Science, Technology, Engineering, and Mathematics” and is a new way of looking at education. Instead of teaching concepts like science and math separately in a vacuum or without real world application or reference STEM seeks to integrate other disciplines including Engineering and Technology with Science and Math. STEM tends to be more hands-on and draws from other areas to create learning experiences that are closer to what a person might expect to find in the real world.

The U.S. now ranks 60th in the world in producing scientist and engineers; it has fallen 22% in just the last decade. Our high school students rank 23rd in science and 30th in math. To continue to thrive in a modern world and to prepare our children for lives, jobs, and a culture which increasingly depend on an understanding of science and math, we need to be making a stronger investment in education in Science, Technology, Engineering, and Math (STEM)” … Quoted from the ShopBot Website (ShopBot in Education)

Harris Educational shares ShopBot’s views on Education and the need to improve skills and knowledge, and make more young people aware of and enthusiastic about STEM related career paths. Every person does not necessarily have talents in any given area, but every human being is creative! We are all innate problem solvers and we all invent and create the world around us every day. Digital Fabrication is a great platform to unleash the creative side of every person. Through their ideas and designs young people can build a desire to go a bit further and investigate “how does that work?” and “how can I improve that?” and “how can I share that?” To go further they can learn the geometry and science and other “hard stuff” that helps them get to their goals.

ShopBot Tools are already in use in schools around the world serving a wide range of rolls from educational platforms to job training to tools for art and architecture projects. Many teachers, students, and others have already shared lesson plans, information, instructions, projects, and designs with each other and with ShopBot. ShopBot’s and Harris Educational’s goal is to leverage this material and add to it in order to create a complete modular curriculum that meets the needs of STEM educators for students in Middle School, High School, and College.

Harris Educational will be producing educational materials and publishing them through ShopBot for free distribution and use by anyone that desires to teach Digital Fabrication as part of their STEM educational program. At first we’ll be producing PDF materials that educators can download and use. As time goes on we’ll be producing videos, animations, e-learning modules, and other materials. I’ll be creating teach-the-teacher materials, teacher classroom materials, and student materials. We’ll also leverage the extensive training materials and actual projects that are available through ShopBot for users of their tools.

Work on this project is beginning now and we’ll be publishing materials as they are available so that teachers can begin working with them as soon as possible. This is an ongoing, evolving, and living project! We’ll be working with educators for suggestions, peer review, and feedback. We’ll then improve and add to the content as time goes on. If you use a ShopBot in your school (or are considering it) you can contact us to help with our project! You can contact Harris Educational at or through our website at You can contact ShopBot tools at (for questions about ShopBots or Purchasing a ShopBot please contact them, to be a part of the curriculum project please contact Harris Educational)

Stay tuned to our blog for further information and updates. We’ll make announcements as we publish and make new materials available.

If you are a STEM educator reading this blog, then please also consider “liking” us on Facebook (… we are building a community of people who are interested in STEM including students, teachers, and every day people including some leading figures in the worlds of Science and Technology. We also have a LOT of free resources for educators available at our website at:

My Visit to the FREEDM Systems Center (part 1)

My Visit to the FREEDM Systems Center (part 1) and the answer to our Identify It Challenge from 7-7-2010

On July 7th 2010 I was the guest of the FREEDM Systems Center at North Carolina State University where I gave a presentation to a group of high school students and teachers about “Engineering, Energy, and Edison.” The presentation included a demonstration of my Reinventing Edison: Build your own Light Bulb kit that was very well received. After the presentation I was treated to a guided tour behind the scenes at the center.

This is the first of a two part article about my visit focusing on my educational presentation. It will also reveal the answer to my “Identify It Challenge” from 7-7-10 that by design was integrated into my presentation. The second part of this article will be posted soon and will focus on my tour of the FREEDM center.

Light Socket Electrical Adapters (Circa 1930's/1940's)

Light Socket Electrical Adapters (Circa 1930's/1940's)

The above picture was the “Identify It Challenge” from our fan page on Facebook ( from 7-7-2010. After introducing myself, sumarizing what I was going to be talking about in the presentation, and teasing the audience with a few vocabulary words to look out for I passed these objects around the room and asked everyone to think about what they were, what they were made of, how old they might be, and what they were used for.

The items are (from left to right):

1) A light socket adapter (with standard Edison style screw base and two non polarized non grounded electrical outlets) This adapter allows a bulb to be used simultaneously while other electrical items are plugged into the adapter.

2) A light socket adapter (with standard Edison style screw base and one non polarized non grounded electrical outlet) This adapter does not allow for the simultaneous use of a bulb while an electrical item is plugged in.

3) An electrical outlet multiplier (makes one plug into three) non polarized and non grounded.

All three of these items are made of Bakelite plastic and were manufactured at some point in the late 1930’s or early 1940’s. Bakelite was one of the first natural plastics and was used to replace wood, paper, and other less suitable materials as an electrical insulator in early electrical devices.

So why did I include these items as the opening of my presentation about energy and Edison and why did I also choose them as the Identify It item for the same week? The answer lies in the use for these items and the circumstances that lead to the need for that use. That need also exists today, simply in a different form.

So why were these items needed? Edison created a demand for electricity to be brought into homes because his light bulbs demanded a D.C. Supply from HIS electrical power stations. Before the light bulb there were no electrical appliances or devices in peoples homes. So houses and buildings were retrofit for wiring. Later, after A.C. Power won out over D.C. in the “War of the Currents” homes were still being retrofit.

The first wiring was simply for electrical lighting, the only electrical device you could buy for a home. Each room may have had a single light switch leading to an overhead light fixture and no other connections. Soon the commercialization of electric motors and heating elements spawned hundreds of devices that people wanted to use. Later in the 1930’s and 1940’s people added electronic devices like radios to the growing list of electrical items they needed to plug in.

So a home owner found themselves with a hand full of gadgets and only one electrical outlet in a room, and that was taken up by a light bulb! As a result these adapters were invented. With them you could plug a device into the overhead light fixture and the miracles of modern conveniences were at peoples fingertips. Miracle at least until many home owners suffered from electrical fires by plugging in too many items and drawing much more current than the simple lighting circuits were designed for!

There are two points to be made here (the reason for my picking these items, including them in the lecture and in the Identify It)…

The first point is one of infrastructure. Edison is not actually the inventor of the incandescent light bulb. He’s credited with the invention but he was not the first. He did make it to the patent office faster than most (even before he had working examples) which is one reason he is hailed as the inventor of the bulb. But the real reason he is considered the father of electrical lighting is because he didn’t just make the bulbs, he created the entire infrastructure needed to manufacture, market, supply, add wiring, supply electricity, and bill for that electricity. He wasn’t selling bulbs, he was selling devices that used electricity. The profit was in selling electricity! In the process he (and his muckers) created fuses, junction boxes, conduits, the light bulb’s screw base, switches, dynamos, power meters and hundreds of other items needed before you could ever see white light stream out of a heated cotton thread.

The second point is about being able to foresee the future and forecast future demand. Edison created a need for electricity and the addition of electrical wiring to homes and buildings. His business model was similar to that of gas lighting companies (early light fixtures were even made of brass and mimicked the gas light fixtures). Edison for all his brilliance did not really foresee the hundreds of electrical devices that people would also want to buy and use. As a result wiring went from a single bulb fixture mounted to the ceiling of a room, to a bulb adapter crowded with cords hanging from that fixture posing a fire hazard, to expanded more modern wiring and the addition of more circuits. Even so we still use power strips (more modern safer ones) to keep all of our stuff going. But with every new device we add more load to the system.

The folks at the FREEDM center that asked me to give the presentation wanted me to focus on energy and on innovation and this is where things all tie together. If you buy a home today that was built in the 1960’s or early 1970’s its not uncommon for a room to have one electrical outlet on each wall (or perhaps not even on each wall). Designers and code makers then assumed you might have a lamp or two, maybe a TV or Radio, and may plug and unplug other gadgets as needed. Today it would be great to have six outlets on every wall because of all of our gadgets. Computers, cell phones, mp3 players, fax machines, phones all the things that need power. Most devices actually run on D.C. power converted from A.C. by an internal power supply or a power brick plugged into the wall. All of this was not foreseen in the 1960’s and 1970’s.

Flash forward and ask yourself… what will electricity supply and use look like in the future? If we do move away from gasoline powered vehicles to electrically powered vehicles then we’ll need to recharge those vehicles (another kind of electrical supply, more outlets… how many? 1? 2? what will the plug look like? Will it be D.C. or A.C.? Will folks have dangerous Y-adapters to split their charging output so that they can charge their own two cars and then also Juniors new car at the same time?)

Its impossible for anyone to fully predict the future. Changes in technology, availability of resources, and millions of other factors make futurism impossible to get right. But the high school students sitting in my demonstration and lecture are going to be the next wave of electricity consumers, inventors and engineers, technicians and educators and so its important for them to try to foresee the implications of their ideas and be prepared for the future in order to prevent the need for things like quick/cheap/possibly unsafe adapters like those pictured above or their equivalent in future technology.

The electrical grid we use today is the legacy of over 100 years of almost organic growth and expansion. Its not to say that reasoning and planning did not go into the design of the components of that grid because in reality it represents a monumental engineering feat that most of the time we can take for granted as we switch on our latest gadget and have that gadget “just work”. But its important to think about energy related issues in our day to day lives. How can we cut down on energy use. How can we stop energy waste? How can we safely and economically expand and create a new smart grid that will adjust to demand. How can we comfortably switch from non renewable centralized generation of energy by burning coal and fossil fuels and move to a distributed system where every home or device might produce as well as consume electricity. All of these questions are being researched at the FREEDM center, and the curriculum taught to students in their program on innovation reflects these questions.

An Engaging Demonstration for Reinventing Edison: Build your own Light Bulb

It never fails.  I get the same reaction, whether I present to seasoned physicists, grade level science teachers or even from the most discerning audience I’ve had; a group of fifty – fourth grade students, jaws gape and sounds ofoohsaahs and wows issue forth.

Lee Walker Demonstrates Reinventing Edison to Educators

Lee Walker Demonstrates Reinventing Edison to Educators

I’ve been in rooms surrounded by hundreds of artificial light sources, from the simplest incandescent bulbs to the most advanced OLED displays, and even so, when a person closes that knife switch and current begins to flow and a simple piece of pencil lead held suspended inside a partially evacuated chamber starts to glow brighter, brighter, and finally white light illuminates the chamber, something happens in the person’s brain.  At once they are connected with the wonders that Sir Humphry Davy, Swan, and Edison felt when they experimented with the world’s first electrical light sources.  Questions start to form; How does that work? How could we make it last longer? What would happen if we changed the carbon for some other material?  All at once, the passive viewer is thinking scientifically, asking questions, and yearning to do more.

I’m talking about “Reinventing Edison: Build your own Light Bulb, a science kit that I am proud to have designed…..
