Oh no! Our Arduino! It’s Broken!

(almost broken by intentional smashing onto the ground but they’re expensive so I decided not to)

AT&T MicroCell Teardown

The electronic piece that I took for the teardown is the AT&T Microcell. I thought Wi-Fi routers are pretty interesting as I had some prior experience with putting electronics together (I put together my own PC) and I thought the motherboard for the router should be quite similar to the PC ones. Therefore I decided to give it a try. 

Step 1: The first step to take the components apart is to remove sticker from bottom of case to reveal the 2 screws and unscrew them. After taking the screws out, pull the orange part away (initially I thought they were glued together, but then I realized that they were snapped together so I had to pull them apart). 

My naive self was actually trying to cut it in half but then reality has proven me wrong.

Step 2: Once the orange part comes out, check the interior to see which side is screwed together with the motherboard. This is important because this helps identify which part needs to be taken apart first (which is the part that is not screwed with the motherboard).

Step 3: After identifying, unsnap the white siding that was not screwed with the motherboard and unscrew the 4 corners of the PCB.

Step 4: After taking one of the white slidings out, remove the other white sliding.

Tools used: Screwdriver, X-acto knife, plier.

List of components and materials:

The Ralink and the other picoChip are two System-on Chips.

Manufacturing Techniques:

  • SSH port on base-station, Nmap OS, and service versioning reports
  • The router was built like a tower/cell with a bright orange to give a sense of energy while providing network coverage.

I’m Jacey ⸂⸂⸜(രᴗര๑)⸝⸃⸃

Hi! My name is Jacey. I was born in Guangdong, China, and raised in Vancouver, Canada. I went to Parsons School of Design for my undergrad degree, majoring in Communication Design and double minors in Immersive Storytelling (basically a mix of design and technology like 3D, AR/VR, and UIX) and Japanese Studies. I have a background in brand identity design, editorial and typography, UI/UX, and 3D modeling. I graduated in May 2022 (this year!) and was a design apprentice under a digital marketing company named REQ during the summer. I have a very chonky cat named Chimmy (he’s 3!), a rescued cat that I got when he was 3 months old (^-^*)ノ I look forward to the sewing sections of the class because I have barely done it before ( •̀ᴗ•́ )و ̑̑ and I like random weird (dark humor) memes from Reddit so there’s that as well (´∀`)
