  Electronics Online Challenge iPod Touch 5th Generation   Created By: Nathan Ramachandran, Shan Ramachandran, Josh Baker, and Caleb Filan.       Throughout the past few weeks, we have been working vigorously on the Texas Instruments Electronics Online Challenge. For this particular STEM Project, we have meticulously deconstructed an iPod Touch 5th Generation. We decided to take this object apart because first, it was one of the few devices we had on hand. Secondly, we have always been wondering what components make up the device that we use so frequently in our daily lives. During this short essay reflecting our findings, you will have the chance to see exquisite pictures of the interesting parts that are inside an iPod Touch. In the iPod Touch, there are multiple key components. There is an A8 chip with a 64-bit architecture and an M8 motion coprocessor. A wifi antenna is hidden within the device. The battery which provides 3.8Wh at 3.7V is a built-in rechargeable lithium-ion battery. The camera is an 8MP iSight camera with a five element lens. There is a 1080p HD video recording device on the back of the device. On the bottom of the iPod, there is a 3.5 mm headphone jack, lightning connector, and a built-in speaker. The operating system is the iOS 10. All of these elements play vital roles in the way that the system functions. To start off with, the M8 motion coprocessor continuously measures data from the accelerometer, compass, gyroscope, and the barometer. The iPod’s battery is so advanced that it is made to squeeze every last second of its battery life out of the Li-ion power source. The HD video recording device can go up to 30 frames per second and it has audio. When you are on any type of app, you can click the home button and it will take you back to the home screen. The volume buttons control the level of noise coming from the device. There is one more button on the top right corner of the iPod Touch and that is the power on/off button. If one would like to listen to some type of audio in headphones they can plug in the wire to the 3.5 mm headphone jack on the bottom left corner of the iPod. Also the iPod features a built in speaker system. All in all, throughout the course of this project we have learned many lessons. One of the lessons we learned were that you have to be careful taking the electronics apart and we have always taken these electronics for granted and never really realized how much work must go into making one of these devices. iPods are very fragile mostly because of the glass screen and a few of the microscopic parts inside.  If you are not careful taking the iPod apart you can risk damaging the iPod's screen and the device not functioning anymore. We have gained so much knowledge about the elements and their roles in how the iPod touch functions. Lastly, we have developed a profound liking towards this area of work.
