Electronics Online Challenge Sponsored by Texas Instruments
Back by popular demand! Texas Instruments (TI) is one of the largest semiconductor design and manufacturing companies in the world. That means we make amazing technology that is inside many of the most innovative electronic products you use every day. For example, you may not have realized it but TI technology is at the heart of the VEX IQ controller and many TI components are used inside the device. We want to challenge you to look at your world with the eyes of an engineer and explore the inner-workings of an electronic device of your choice. Once you choose a product, you will deconstruct the device, catalog what you find inside, and then submit a final report with your findings on what you discovered.
TI technology is also probably inside many of the electronic products you use every day. For example, TI components are inside the VEX IQ controller, BEATS headphones, GoPro Hero 4 camera, Tesla cars, and the Samsung Galaxy. We challenge you to find a device (we recommend choosing something you don’t mind breaking apart, for example an old phone), and carefully deconstruct the device so you can find out what electronic components are inside. Most semiconductor chips are labeled with the company name and component name. Then conduct online research to discover what the component does and what its role might be within the entire system of the electronic device.
Here are a few ideas to get you started:
- Smart phone, tablet or mobile device
- Camera, voice recorder, video camera, tv remote
- Headphones, speakers, music player
- Watch, Pedometer, GPS navigator, Garage door opener
- Computer components like mouse, monitor, keyboard
SAFETY TIPS: Before starting this challenge, make sure to have your chosen device approved by your team coach/leader/mentor/parent for safety purposes. Also note that some devices contain capacitors that hold a charge and extreme caution should be used. Any electrical device that contains a power source must be disconnected or removed before disassembly (unplug all cords and remove all batteries). You must wear safety glasses during the disassembly process.
Our students worked very hard on this, because we struggled to find conclusive research. Also, there was pressure to do this a fast as possible because we had now idea when or if we were going to get quarintined. In Conclusion, our students worked very hard and poured their heart and soul into this project. Thanks for considering us, 214A, for this challenge.

I chose a Motorola flip phone to tear down. I found it sitting around our house and I had never seen a phone like this before. I thought it would be cool to take it apart.

I selected a Jelly Comb wireless 2.3 GHz mouse to deconstruct because many of us use a mouse every day to navigate the internet, join zoom meetings, and submit assignments, but we hardly think anything of it. The mouse allows us to insert ourselves into the computer and control what it does by just moving our wrists and clicking a few buttons. A wireless mouse, specifically, allows us to do all of this via the mouse and receiver in the computer communicating over a specific radio frequency. And the mouse does all of this by taking thousands of photos a second, analyzing those photos, and...
These days, integrated circuits (ICs) are often dismissed as nothing more than a magic black box. However, the inner workings of these "chips" are a fascinating and under-appreciated part of electronics. Therefore, our team, from Auckland, New Zealand, chose to disassemble (‘decap’) a Texas Instruments SN7404 hex NOT gate to better understand how it worked.
To remove the plastic casing and reveal the silicon die inside, we used sulfuric acid heated to 90˚C (194˚ F). This slowly dissolved it, leaving the die which was inspected under a microscope. We learned...
Sean Covarrubias is a very talented student engineer. He throughly enjoyed deconstructing the Fender amplifier. He learned about many components and their function within the final product. Although he was not able to locate any parts manufactured by Texas Instruments in the amplifier, he has since deconstructed additional products and found TI components. He continues to learn and strive for his goal to become a mechanical engineer for the biomedical industry.
Our team, team 9007A, decided to open a TI-30XIIS calculator. We chose to open a calculator because it is simple to assemble and disassemble. It is also very cheap, unlike a phone, which is expensive. It has less parts which makes it easy to keep track of all the assembled and disassembled parts. It is also easy to know the external and internal components. Finally, the calculator is a very safe device to handle.
We are a team of 3 member middle schoolers from Cumming GA, For this project, we decided to break down a 2007 model Toshiba satellite computer. It has various and very different components such as a motherboard, keyboard circuit, processor, and battery. Each of these components is different and has a multitude of purposes. It was easy to take apart but hard to put back together.
Team 8838E - Energy: An Orchard Hills Robohawks Middle School VEX EDR team. This project consists of the deconstruction of a Texas Instruments calculator: the TI-36X Solar.
This year for the 2020-2021 Texas Instruments online challenge, Katie Hannah from team 8838A Discovery decided to deconstruct a Netgear WiFi range extender. The entry covers the components of the extender and how everything works together.

Our Team PUPR Vex Robotics is composed by a diverse group of students from the Polytechnic University of Puerto Rico. We have students from different branches of engineering such as mechanical, computer, electrical and chemical engineering. We are excited to introduce you to the 2020-2021 Electronics Online Challenge.
We are students from Ridley college, Crest wood and PCA. Two of us (Zachery and Jason) are in grade 10, and two (Bobo and Alex) are in grade 9. This is our first year participating in the VEX EDR challenge. We are team 16610C. Our Online Challenge is Texas instrument and we chose to disassemble a VEX EDR controller. From this, we learned about CPU, RAM, and how the controller sends signals.
For the Electronics Online Challenge, sponsored by Texas Instruments, team 141A decided to reverse engineer a garage door opener remote. We learned how a circuit board works, how to use a multimeter, decoding many parts, and many things besides. We hope you enjoy our essay discussing how a garage door opener remote works, and the many components that make it up.
For this project, we decided to deconstruct a Vex Transmitter and Receiver. Due to the long history of our club, we have a lot of old Vex parts lying around. We ended up taking apart this 2006 version of a controller so we can see the improvements not just visually on the outside, but also for the components on the inside.
We are a team that consists of 5 sophomore members from Michigan. As a team, we are passionate about what we can bring to the competition.
For this challenge, we took apart a laptop to examine its intricate inner workings. Our team learned a lot from this experience.
In this report, the American High School Vex Robotics students explore and examine the interiors and the circuit of a digital multimeter. We disassemble the multimeter and inspect key electronic components in detail and discuss their role in the circuit. We further analyze and gain a broader understanding of the function of each component as well as of electronics in general.
I chose the electronic online challenge sponsored by Texas Instruments. The object I chose to take apart to see what components were inside of it was a Logitech m305 wireless mouse. This seemed like a good choice because mouses are used in everyday life and needed by almost everyone with a computer.
Beneath the right and left buttons on the top of the mouse, there are little boxes that can be pressed and sends a command through the circuit board to the usb wireless receiver and performs the command it was sent on the computer. This device also has a scroll...
