DroidCon 2016

6/26/2016

0 Comments

 
On June 18, the Midwest Astromech Builders had an important, bi-yearly meeting: DroidCon!

DroidCon is a gathering of all of the Midwest Builders from Indiana, Michigan, Ohio and Illinois. We share information, look for interesting new ideas, buy and inspect parts, and listen to speeches on various R2-related subjects. While I was there, I bought some hinges to allow my droid to open its "pie panels" - the blue panels on the top of R2's head. 

All of DroidCon's participants were friendly and helpful, willing to assist beginners, and even talk to members of the public just stopping by to gawk. Most were also very knowledgeable about the best ways to build an R2, how to keep it running, what was and wasn't possible, and anything else you could possibly want to know when building an R2. 

Most people bring their R2s or other droids (such as mouse droids and R9s) to DroidCon. This year doubled the last DroidCon's attendance with over 100 attendees. It also had almost twenty R2-D2s, the most I have ever seen in one place at one time!

Indiana Tech Engineering Camp

Last Sunday, June 12th, I moved into Indiana Tech’s dorms and began my first afternoon of a week-long Engineering Camp for high school students. It marked the beginning of an incredible time and a plethora of knowledge to be found! 
 
All of the engineering courses were combined this year to give campers a multidisciplinary experience. On the first full day, we started with Mechanical Engineering classes. Our very first project was to identify the various parts of a camera that had been created by mechanical engineers. There were dozens of them! Only the circuit board and its code had not been made by MEs. We then moved on to make "Water-Zookas", a giant water cannon to be used in the water fight against Computer Science. After lunch, we formed into groups and tried to build the sturdiest tower. My team won with a pyramidal design that could withstand a more powerful earthquake than any of the other structures by .2 Hertz. As the prize, we were allowed to choose our next project first: one of da Vinci's many designs! I chose the catapult and when building it, I added extra tension to give the projectile more distance.
 
The next day we began the Electrical Engineering course. We were all given 5 circuit kits to complete at our own pace. These included an Infrared LED motion detector, an LED oscillator, a light-sensing robotic insect, voice-activated LEDs, and a voice changer. They were supposed to last us 3 days. I completed mine in 5 hours, so Professor Byers, one of the amazing teachers at the electrical engineering camp, gave me a special project to complete: use a touchscreen shield with an Arduino Uno and put a clock or a chalkboard on it. I spent the next two days working with it and learning how to load new libraries from folders other than in the Arduino's system files. I also learned how to find the most important pieces of code without any comments to guide me, and how to research solutions to coding problems. On Thursday, the second to last day of camp, we finally got it working! We then attempted to build the game of snake on an 8x8 LED Dot Matrix display, but because of the strange pinout on the display and the time constraints, we were unable to complete the project.
 
The opportunities I had to work one-on-one with Professor Byers and Professor Rumsey were the highlights of the camp. They are both amazing teachers and I am looking forward to working with them again next year!
 
On the final day of camp, Professor Byers had me bring in my R2-D2 robot as a demonstration of what can be done with engineering and computer science. The students loved it! None had ever laid eyes on a functional R2 before, and all of them had tons of excellent questions about what went into building it, how long it took, what boards I designed, and many more. It was the perfect way to end a perfect week!

Arduino Shield

R2D2 components can be very hard to come by at times. The center foot, for example, is a special piece that can only be created by a few people who make very few of them. Another now-difficult part to find is the PS2 connector board for an R2.

For R2 builders, there used to be one main source who built the majority of the boards. Recently, the supplier has shut down production of the boards so he can begin outsourcing the entire process to China, which may take years to complete. Now there are very few unused boards left for new builders or builders with R2s who need new boards.

Fortunately, I have made my own board, which you can find in this blog: http://www.alexandraforsythe.com/blog/ps2-adruino-shield
. Since the blog was written, I have created several more boards and I will begin manufacturing and selling them to other builders once I have finished the testing process.
