How To: Samsung Galaxy S7 Battery Replacement
Batteries in the top of the line cell phones typically only last 2-3 years, yet those phones cost nearly a thousand dollars (or more). The battery in my wife’s Samsung Galaxy S7 was not holding a charge. Our decision: do we buy a new phone or simply replace the battery? As it turns out, it only cost $15 to replace the battery ourselves vs. $700+ for a new phone. This video will show you how to do it yourself! This video is NOT for the S7 Edge.
Warning: Repairs will void the warranty with your service provider and manufacturer of the phone. Also, a few cautions: Don't use metal tools when prying the battery up, use the plastic guitar pick/prying tool instead. Use proper eye protection and follow all manufacturers recommendations above all else. Adding additional sealant is up to you, I reused what was there but keep in mind it will not be as water resistant.

Building a single-panel JUMBOTRON using HACKERBOXES 0036
This month’s Hackerbox #0036 I found very interesting. In the box was a single RGB LED Matrix with 64×32 pixels! It’s one of the panels that is used for making those massive retro arcade classics that you see at Dave & Busters, Stars and Strikes, etc. I’ve always wanted to see what these panels look like and work with one, Hackerbox delivered! Let’s check it out!
