Jie Qi has been beyond gracious in asking educators like myself and others like David Cole, Jill Dawson, K-Fai Steele, Ryan Jenkins, and Sebastian Martin over at The Tinkering Studio to play with her new circuit board. Everyone has had different ideas of how to learn how to use it. Some have tried a clip, I tried two magnetic strips to try to keep the board flat in my electric notebook. So look at my twitter feed and @chibitronics to see the cool stuff coming out of this exploration. Thank you Jie for the fun opportunity to play, learn, and share what I learned..!
First, when David Cole gave me my board from Jie I tried to pirate another paper circuit in my notebook at Fab Learn 2016 and tried to program it with my iPhone. It seemed to transmit once then nada. Then I saw that Ryan Jenkins was at the conference and I tweeted him to see if he could give me pointers. Several of us were invited to the Exploratorium in San Francisco for a post-conference meet-up to discuss paper circuits and Jie's new board. Ryan and Sebastian had a pile of Jie's new boards so we got down to business trying to learn from them. K-Fai and Ryan had some issues with lining up the board to the circuits and we couldn't get it to run right. He said he could not get it to work with the iPhone but was able to do so with his Mac Air. But K-Fai did say to push down the green programming button the whole time to program it, which I remembered later. She brought more prototyping boards to share with everyone.
Went home and still had issues. I had to plug in to my phone, the board, and the USB in my computer for it all to work. Then the board got hot and I was sure I had fried it and my countenance really fell. Then I saw Jill Dawson had success with hers so we spent some nice chat time getting 'er to work. She reminded me to push the program button down until it turns red. It was good to confide in Jill about my fried chip worry. She confided she had fried one of her boards in her learning. See...we all learn from each other. Now David needs me to walk him through and that's the open source mindset. This is what my teachers and students need too ...just show us how and we are off inventing and creating cool stuff that we love to share.
Thank you Seymour Papert!
I first saw Per-Ivan Koen's work with the #Attiny85 on a Google+ post and I immediately recognized what he had done as significant in making #papercircuit projects easier. He said he used a vinyl cutter with tee-shirt vinyl to create a stencil, which he then used Bare Conductive ink and a credit card to print or silk screen. Amazing! What was even more fun was while tweeting at #fablearn I saw a photo of him and Leah Beuchlely he had tweeted and realizing he was there in the same room all the way from Holland.
I immediately tweeted him and asked if he had brought samples and we hooked up at break. We were joined by Erin Riley and Tracy Rudzitis and discovered all the cool things he was working on. He gave me a stencil and a print I could use. Later at the Tinkering studio he gave me a smaller stencil with a smaller embroidery hoop. I am anxious to try it out and maybe make some directional changes. I love the black layout as graphic art and what is quite fun is he put a pink vinyl stencil on his Fab Learn shirt.
At the Tinkering studio Per-Ivan explained his new idea that you can see in the photo with a round blue Attiny85. Per-Ivan lays down his copper circuit and then bends two pins on each side out and presses the microprocessor through so it makes contact underneath the paper and then bends the pin or leg down to secure it. Brilliant..!
Thank you Sebastian Martin and Ryan Jenkins for inviting us to the Tinkering Studio for a Fab Learn 20165 post-conference to discuss new developments and share our making and tinkering experiences with #papercircuits and the #Attiny85. Bridget Rigby and David Cole of Nexmap were there arlong with Angela Sophia Lombardo from Italy, Per-Ivar Kloen from Holland, K-Fai Steele, and some new FabLearn fellows. We enjoyed the paper circuit cards the Tinkering studio was tinkering with along with investigating Jie Qi's new circuit board. Look in the middle of the table and you will see a pile of Jie's new @Chibitronics boards.
As part of a collaboration between Nexmap, KQED, Educator Innovator, The National Writing Project, and Letters to the Next President I helped design a #papercircuit template for California's Voting Patterns, which was shared August 25, 2016 on the Educator Innovator 3-part webinar hosted by our very own David Cole showing how to integrate engineering into civic literacy and incorporating the #Attiny85 microprocessor into an election year project . You will see a yelllow mini-breadboard with a Sparkfun Tiny Programmer used to test the various fading patterns I designed to show different county voting patterns. The program for the fade is below. Just add more @Chibitronics circuit stickers.
What an amazing trip up to Kodiak Alaska. Words and photos cannot express the beauty of Gods' creation. I had no idea but was up for the adventure thinking we were going to get our geek on for three days straight.Teachers came from all across the state to see their screen buddies from hundreds of miles apart. Because of the long days we did not end the days at 5:00 but stayed up way into the evening when it was still daylight at 11:00 and we could not sleep. That was a treat to just relax with my new friends who were beyond friendly and by the end of the conference I felt like I belonged. I met so many friends in person like Nicole Fuerst and Emmanuela Pokryfki, whom I just loved working with.
David Cole of Nexmap and I came up at the request of Nicole Fuerst of AK Teach and David and I got very ambitious the week before and decided to create an even deeper learning opportunity. We originally were only going to teach the #ATtiny85 programming with #papercircuits and add servos, but we ordered a bunch of electronics to show teachers how to make their own LED test boards and Servo test boards too. Besides this we wanted to teach them how to make their own engineering kit from scratch and to think like an engineer and to solve problems, because they are on a budget too.
Teachers learned how to make the parts for their paper robots and solder leads onto servos, shrink wrap, extend LED's on wires, make their own 9V battery holders with smooth aligator clips, and how to reduce voltage from 9V down to 5V using a 5 volt regulator and capacitors. Because we didn't think of this in time, our half-size breadboards did not come in. One physics teacher set out to solve the problem and shrank everything onto a mini-breadboard. That set everyone off wanting to make their own test LED and Servotest boards and there was a mad dash to get 'er done before we ran out of time.
My most favorite part besides all the innovation and ingenuity of everyone and the beautifully designed #papercircuit projects was coming in the next morning on day 2 and hearing how teachers went back to their bed and breakfast inns and stayed up figuring out and making their paper circuits and finding them already working on their projects when I walked in. We could not have asked for a better crew. I feel that we accomplished more than we set out to do and set up a band of teachers to go out and spread the learning all across Alaska. An incredible experience to say the least working with very adventurous teachers who took their projects way beyond expectations, even connecting two ATtiny85's in tandem with one power source just like Jie Qi did with her Dandelion Painting, an inspiration to us all.
I am so excited to be invited to fly all the way to Kodiak Island, Alaska from California this June to present at the AK Teach 3-day Kodiak Island Borough School District “Make and Play: 2016 Kodiak Island Virtual and STEM Learning Conference. The photos are my paper prototypes as I create a story around the Kodiak Island Alutiiq Eskimo heritage and is about a Kodiak Alutiiq Bear Family. Using simple coding, or programming, microchips, LED's, and servos, I will make the Alutiiq Kodiak Bear robot animate and move. See if you can tell what the story will be about. I would love to hear you share your ideas. My goal is to help educators see how easy it would be to incorporate storytelling and paper circuit engineering, or paper mechatronics, as a means to teach literacy within an electric notebook.
When I land up there my task is to teach educators how to build paper circuits with copper tape, and then program them to blink with an ATtiny85. Before I leave, my workshopee's will all have built robots from scratch and know how programming and robotics fundamentals work.Teachers will have a firm foundation on which to build and grow not only their knowledge but their students.
Of all places that recognize the importance of bringing modern engineering technology such as real programming, and authentic robotics into the classroom it is far away Alaska that has stepped up to this emerging field.
Alaska gets it. What do they get? Nicole Fuerst, Communications Coordinator for Kodiak Island Borough School District has experienced a strong desire to provide this knowledge to her students and teachers in a way that maximizes learning and equips children to research new projects. Nicole has been a strong proponent of paper circuits and organized the conference.
The impact of these beginning and advanced paper circuitry and programming workshops is significant, though only now beginning to be widely researched in K12 Education. I am going to be bold and say paper circuitry is the very foundation of how to start an engineering program for an after-school or in school MakerSpace, or library. I feel we must tie in lifelong learning and self-directed learning in the conversation, which are "buzzwords" being thrown all over the internet along with equity and access. These buzzwords suggest that it is enough that children can be given robotic kits and simple coding exercises and voila! they want to be future computer scientists. Is this what we are seeing happen in our schools?
While I my thoughts are quite open, kits and code sites do serve a purpose, that is to propel the student into deeper thinking about how do all these kits work? Truly the next step after learning logic is learning how things work. These things that are important to know are the separate parts that make up kits. Does a cute kit supply everything? We limit childrens' knowledge to kits when we do this. If we are going to lead ourselves, our students, our teachers along the learning path to a future STEM career we have to take the next step once we understand how kits work. Yes, we can hook them with the kit, but with any kit like my beloved Makey-Makey that my students prototyped for weeks with, there needs to be the next step. That next step is understanding how those proprietary circuit boards work and how to make their own.
So back to Alaska. They get it. They have limited funds. They have long-distance issues. Nicole has students that may be 800 miles away and she has to be able to bring this engineering technology to her students. The best, affordable, and fastest way is through paper circuits. They are immediately accessible, filled with immeasurable opportunities for creativity and artistic self-expression, and when combined with other subjects, literacy flowers. I am saying this from years of experience in literacy teaching self-contained middle school classes where we creatively integrated writing into history and other subjects. Children learn when they make things that express their own experiences and interests.
Alaska here I come...!
I cannot tell you how happy I felt to be asked to come to Alaska to present at The Virtual STEM Conference on Kodiak Island. I did not have any knowledge about Kodiak and began what turned into a journey into the island history of the Alutiiq Eskimo Tribe and their life before the Russians and afterwards. I discovered the rich traditions, native dress, customs, foods, and way of life and it became a PBL, or project based lesson as I asked myself the question, Who are the Alutiiq? By the time I landed on Raven Airlines, I already felt I knew Kodiak.
I was fascinated by the beautiful way of ornamenting their clothing and was able to virtually drop into their local museum and study so many artifacts. I found out about the petroglyphs. I also studied local tribal gatherings and loved the tatoos and the many variations in individual style. I have always loved wildlife and found that the bald eagle lives there too, along with the Kodiak bear, and the Sockeye Salmon among other inhabitants. Salmonberries were all over. I created this #papercircuit electric diorama that I programmed as an example of teachers can incorporate literacy as a way to narrate a story in a literature and social studies class.
Here is another great solution to controlling the 5 volts maximum power your ATtiny85 can handle. Servos need 5 volts themselves and this is a great solution. Yes, you can buy a converter such as snapVCC for $13 or wire it up just as shown using a 5 volt regulator and two ceramic capacitors Jameco #334 0.33uF and a Jameco #104 0.1uF for only $1.77? More importantly now you know how it works and you can use this same 9 volt to 5 volt set up for other projects! We are planning on making these to use as test boards when programming ATtiny85/84's or larger microprocessors to test LED patterns. Plus we can set this same board up to test servo angle patterns. We will use this board over and over again. Amazon and Jameco carry these. See my earlier post "What is a Capacitor for?" for more information on how capacitors and here to how 5 volt regulators work.

A month from now, AKTEACH and Kodiak Island Borough School District will hold “Make and Play: 2016 Kodiak Island Virtual and STEM Learning Conference,” and while statewide registration has closed, AKTEACH still kept registration open for KIBSD educators to attend the conference June 6-8.
KIBSD teachers and staff interested in attending can register at www.akteach.com or contact Nicole Fuerst, Statewide Distance Learning Professional Development Coordinator for AKTEACH and VLC organizer, at 907-942-0537 or via email at email@example.com.
You definitely will not want to miss this VLC.
The keynote speaker and feature workshop presenter for this year’s VLC is the ASTE 2015 Teacher of the Year and Coordinator for the Learning Design and Technology Program at the University of Alaska Southeast Dr. Lee Graham. The conference will feature a three-day Mini-Maker Faire, as well as a number of interesting and informative strands, including STEM in Distance Learning, KIBSD Distance Learning Tools and UAV Piloting.
Additionally, the 2016 VLC will offer two strands on paper circuitry. “Elementary Paper Circuitry” will be taught by Peggy Azuyak, AKTEACH’s grades 7-12 homeschool/correspondence coordinator, and Jeannine Huffman, an adjunct faculty member at the Teachers College of San Joaquin, will present “Advanced Paper Circuitry.” Huffman also has worked for the last several years with a group of educators at the Da Vinci Center for Innovative Education housed at the San Joaquin County Office of Education, tinkering and making — engineering — anything and teaching children and educators how to do the same.
So, what is paper circuitry, you ask, and why the focus on it? Paper circuits are functioning electronic circuits built on a paper surface instead of on a printed circuit board. Because of their simplicity, paper circuits are becoming more and more popular in the hobby electronics world as it is possible to make a wide range of projects from greeting cards to origami to traditional art, such as paintings or drawings.
According to Fuerst, paper circuitry also is finding its way into the classroom through electrical and creative education. “It really is amazing,” she explains. “It is one of the most acceptable ways to integrate a STEM or STEAM activity into the classroom. There is a low-barrier of accessibility. All of the materials are things teachers and students are comfortable with — paper, simple batteries, tape and stickers. The circuit is easy to work with and build, and makes fabrication, engineering and electricity a lot more interesting to the classroom.”
Teachers can use paper circuitry to teach in variety of ways: basics of circuits, the flow of electrons, problem-solving, trouble-shooting (why doesn't the circuit work?). As the assignments and circuits become more advanced, educators are employing the idea of "hard fun,” which requires students to be more persistent and technical and to trouble-shoot their circuit designs.
Don’t let the title of Azuyak’s “Elementary Paper Circuitry” strand fool you. It is not paper circuitry for elementary school students. Instead, the strand encompasses the basics of paper circuitry. If you are a novice interested in implementing paper circuitry into your classroom curriculum, then this is the strand for you. “Participants in my strand will have hands-on practice with building paper circuits and practicing the design process,” Azuyak says. “We will explore and create using all sorts of conductive materials, such as copper tape, conductive paints, conductive thread and conductive Play Dough. Educators will have time to network and collaborate with each other to develop lesson plans incorporating paper circuitry into their content areas.”
Relatively new to paper circuitry herself, Azuyak was introduced to paper circuitry during last summer’s VLC. Her fascination led her to incorporate it into language lessons, specifically the Alutiiq language. “I wanted to draw an airplane and light it up,” she explains. “I was able to incorporate the Alutiiq Language in my drawing. This encouraged me to incorporate it with my elementary Alutiiq Language students. First, they learn how to build paper circuits. Then, they create an image to light up related to something they have been learning in Alutiiq Language class. ”She adds: “Paper circuitry can be incorporated into any content area…It is a perfect addition to science, but can also be integrated into social studies as well. Students can create a dynamic map of an area they have been studying. Educators have beautifully merged paper circuitry with writing to generate meaningful learning experiences.”
“Advanced Paper Circuitry” will build on the basics of paper circuitry, combining it with coding, LED lights, microprocessors, computers and robotics. “This part is liberating for teachers because they begin to build confidence and see all the possibilities once they experience designing and making their own paper circuit themselves,” Huffman states. “After learning how to code and change variables, we will advance even further to learn how to make the microprocessor control a servo and use that knowledge to build a simple one-output robot. This will be exciting for them because now everything they have learned comes together in one project by combining paper circuits, coding and robots, and they can see how this will translate into their classroom practice.”
Huffman stumbled upon paper circuitry while searching for a less expensive way for her pre-engineering students to construct a robot. “Students could make a complete first coding project for about $2.50. In comparison to a $500-per-student LEGO kit, (paper circuits) are the best and easiest way a teacher can teach students how to learn circuits, coding and robotics, by making their own kits from scratch. This removes so much of the equity and access barriers that so many teachers, schools, and districts face when introducing engineering for all grade levels,” she says. In the end, she notes, using paper circuitry in the classroom opens doors to endless educational possibilities for both teachers and students. “The possibilities of adding sensors and complexity to paper circuitry in not only engineering but integrated in other subjects such as English or history are endless and up to the imagination of the student,” says Huffman. “By the time children learn how to build a simple robot, they are able to teach themselves engineering and can design and build whatever they want and learn all along the way.”
I found out about fritzing at FabLearn 2012 and have used it ever since. What is Fritzing? Fritzing is a free cloud based software that is used to document your work for later reference. You have to try it to see why it is so important. It allows you to safe your work as a photo rather than keeping a physical breadboard model. It is that simple. It even provides a schematic and a PCB version should you want to have a circuit board printed.
How do I use it with my students?
1. Students first build a working model, which could be a simple analog circuit using an LED.
2. Students then have to show me their circuit is working.
3. Students open the Fritzing program and recreate their breadboard with detailed notes so they can recreate the circuit.
4. Students save as a jpeg file and download it to their desktop.
5. Students add the fritz to a word document along with any Arduino code used and write up their project.
Your first experience with a capacitor is usually with a 10uF capacitor when learning to use an Arduino Uno. When you look at the Jameco catalog you see all sorts of choices. So how do you choose? At Learning about Electronics they make it easy for the novice to learn plus there are sample analog and digital projects. What do the numbers on a capacitor mean? Look at my first photo on the blue ceramic capacitor with number 104 printed on it. Now look at the General Capacitance Codebreaker Information photo for 104 and you will see the capacitor is a 0.1uF or a much smaller capacitor. Next, look at the ocher color capcitor and you will see 334, which is 0.33uF (MicroFarad). Finally, for practice, try to identify the other two capacitors shown in another photo. You will need to know this when you have a miscellaneous part that needs to be sorted back into the electronic bins. Mike's Arcade explains more about capacitors and metric conversions. Once you identify the code, you can then switch over to the order catalog and choose a part by Farad. Since my Jim Bock buys the cheapest, so do I.
Now that we can identify, you will notice how nicely Jim in the Delphi Robotics lab has organized his different capacitors easy-peasy. What purpose does a capacitor serve? Learning about Electronics says, "This capacitor is there to filter out any noise coming from the voltage source (the battery)." I need to reduce a 9 volt battery down to 5 volts to protect the ATtiny85 microchip and have enough power for the servos. Enter the 5 volt regulator, which "works best and will be most efficient when a clean DC signal is fed into it. We don't want any ac noise (ripple) imposed on the DC line voltage. The capacitor, in essence, acts as a bypass capacitor. It shorts the AC signal of the voltage signal (which is noise on the voltage signal) to ground and only the DC portion of the signal goes into the regulator." When the voltage is regulated properly, you will see visible smooth servo motion. Lastly, to grow smarter read How does a capacitor work? To learn how to calculate capacitor and resistor values, Instructables is a great place to learn and find projects.
I believe we can make engineering more accessible and equitable if we teach children how to make their own electronic components and parts for their own robotic kit. This deepens their understanding and they can interchange parts or connectors depending on the use. Plus students end up with their own kit.
For instance, a battery pack may need to be able to be plugged into a breadboard with header pins, or an Arduino Uno with a barrel jack, or attached to copper paper circuits with smooth alligator clips. This means kids will learn to solder together wires etc. to make what they need and understand how it works. For me, this was an epiphany...knowing that I could make, hack, or adapt what I needed made me think what else can I change to suite my explorations and tinkering?
So far I have had good success with hacking together parts. In these photos you can see I am focusing on this Hobby King ultra micro servo for a project I am developing. I am trying to figure out how to make different kinds of connectors between copper tape and servos to use with #papercircuits. Ultra servos come with a mini connector but no hint on what to plug them into. What I did was cut the connector off and solder on wires and shrink wrap. This works great for prototyping with a breadboard. What I really like are the larger 3-pin connectors on micro servos because you can easily use header pins on a breadboard for testing as they are easy to make.
What I found with the ultras is the wires are so tiny in diameter and they are stranded that they really are almost too difficult for the average child to manipulate, let alone an adult. I struggled with crimping the wire to the alligator clip and soldering to secure it in place. My last attempt you can see in the photo where I laid down a bead of solder first then added the wire..
My next experiment is to try to use the mini connector size that comes with these servos and find the male counterpart and somehow figure out how to attach that to the copper tape. This Reddit article may help.I think this will be a better solution so the servo can be snapped together and reused in another project, and not be permanently soldered down.
I was asked to visit a local school site today to help a fellow teaching team plan how to incorporate circuits, programming, and robotics with an innovation grant they are applying for. This is a serious question and as I drove to the meeting I had several thoughts, one of which was that this would make a good research topic. Everyone knows about Lego Robotics kits, but not many know about Hummingbird Robotics kits. Myself, I am a firm believer of making your own unkits from scratch so students really understand how things work, but how do you help a teacher who may be just starting?
I narrowed my ideas to three main questions to discuss:
1. What is the teacher skill set?
2. What is the population background?
3. What is the budget?
Right away we started with the main teacher, who already has html programming background and has been using code.org with his students. This is good as programming takes a commitment. Learning programming with Arduino is really not that difficult and students easily pick it up. After sharing the several different avenues to approach, I shared several projects and what I thought were a good order to begin. Kits can easily eat up a budget and leave students without deep knowledge.
The population is a nice, manageable smaller size with older middle and high school students with 1:1 computers. I have worked with a wide variety of similar students and they seemed quite able to manage the learning needed. One student sat in on the meeting and I was quite impressed not only with her eagerness but her code background.
Lastly, with a $2500 budget per teacher, they will be able to explore many facets of engineering and we agreed students should first use 1:4 Lego Robotics kits to learn logic. We also thought they should move to the Hummingbird kits to teach them to use individual components like LED's, servos, and sensors. This will deepen their understanding and is a great start and will help the teachers learn along with their students. What the teacher wants most is to have students learn through simple paper circuits, simple programming and simple robots, but that will take a somewhat higher learning curve and training. Whatever way they decide, be it Lego, Hummingbird, or by scratch with the unkit approach, this team is well on their way to introducing a wonderfully innovative program to their very special students.
When programming an ATtiny85 with a Sparkfun Programmer or an Arduino, you can only see one LED blink and cannot be sure your sketch is working properly. When searching for more complex code I found Lynn Bruning at eTextile Lounge had made several breadboard prototypes. In thinking about it, I realized I could make my own tester breadboard for teaching students and teachers during classes. What a time saver for everyone. Be sure to neaten, or flatten your wires so electrical components stay put. To improve efficiency, I would make three more so no one has to wait to test their sketch. Ultimately, this design could be transferred to a permanent PCB board with a removable 8 pin holder for the ATtiny85.
I was privileged to visit East Bay Innovation Academy's Steam Fest this week and see all the wonderful learning students were doing. In this class they were learning about Paper Circuitry with Chibitronics Circuit Sticker Effects and alligator clips to make reusable cardboard tiles. What I saw were so many engaged students being very creative and solving lots of engineering problems! One student figured out how to add four LED's to his circuit by connecting several in parallel.
Carefully open the phone battery cover as we broke the switch on our first one, which you need to turn off the power. The second video shows me testing a servo on a breadboard build and using the lithion ion battery to power it. It works! ;-)
Thank you David Cole of Nexmap and Natalie Freed for allowing me to have the Tide Book overnight to share at Fab Learn 2015 #fablearn for my demo session, which was so much fun. I am fascinated by this book as are everyone else who has seen it. I was able to really examine the structure of the #papercircuits Natalie created and how the circuits were woven inbetween the spine using conductive fabric tape. What was important to me was being able to see how the telephone battery case was hacked and situated within the book and used as a power source for the book itself and it inspired me to try this myself.
I studied Natalie Freed's book, Jie Qi's book, and Jen Dick's book on the nexmap.org and compared all of the different ways the worked out to engineer a solution. While I have not yet decided to add this to my own book because of the lithium ion battery issue, I was able to hack apart some battery phone charges of the same type Jen used and try out the power source. I have created all the stencils to do this and may install it in another test book.
a.s.h. was a project worked on by an ecclectic team of students, interns, engineers, and teachers. Joe Paulus, Nick Hartzler, Jim Bock, Jason Heimbeck, Nathan Ahmed, Bradley Barker, Brandon Salas, Jarod Kinney, Mitchell Gass, and me. We all had a part and together we learned together and shared our knowledge. The idea started with a broken down robot I was in love with for the last several years that sat up on a shelf in Jim Bock's robotics lab next door. I wanted to learn how to make one myself. We disconnected the old circuit board and were left with four servos. Jason designed a new animated head in 3D on Solidworks. Nick took that design and made a 2D design and cut out another one in wood on our Versa Laser. I had the bright idea to add a red mohawk and using the head shape designed one and cut it out in flourescent pink on the laser cutter. I also made a few heads in cardboard. Once I painted the cardboard heads everyone became interested and jumped on board. Really it was the vivid color and creativity that attracted everyone and noticibly more girls to the project. Look on the acrylic animatronic heads shown on each page.
My original plan was to make three blue men as a nod to the Blue Man performing group for Maker Faire 2013 where our SJCOE Da Vinci Center for Innovative Learning students presented a.s.h. as participants of the DARPA Mentor and Make Makerspace grant, which we were one of ten high schools choosen. Nick lasered one in blue laser. Joe worked on the arduino.cc code and merely added four public domaine servo codes together. We could have stopped there and just programmed a.s.h. to move perhaps in a loop. Instead someone had a bright idea to add a joy stick to rotate the head up and down and side to side. Then a potentiometer was added to control the eyes and a button was added to open the mouth. All four were separate programs, which I will share as time permits. Joe made lots of changes to the code and there are several versions.
Maker Faire was a blast and students loved presenting.a.s.h. was a hit and I will add more photos. Our next iterations were to add LED's to the eyes, and hack a game controller to operate it. We didn't get that far but you might. Later we thought of how neat it would be to control it by our phone. So share with us if you do. I will eventually post the .stl file in time.
