Litecoin Mining Rig - 4 R9 270x GPUs

Cryptocurrency has been a really hot topic in the news for the past few months. Bitcoin and Litecoin are two of the main currencies currently in use. What's special about cryptocurrencies is that they're completely decentralized. There isn't a single entity or company in control like traditional fiat currencies of the world. Everyone has a copy of every transaction that has ever been sent, referred to as the blockchain. Instead of relying on a central server to store these records and carry out the transactions, cryptocurrencies rely on people to lend their computing power to the network. In return, the cryptocurrency network rewards contributors....

Alcohol Bottle Lamp

     Back in college I found a tutorial online on how to light up a glass bottle with some LEDs and crushed glass and started making them for friends and family. I've modified and optimized the original process to make it a bit easier. Here's a list of the required materials:

550 Watt PSU to 12 Volt R/C Charger Power Supply

     Last week I decided to take the plunge into R/C quadcopters. With the help of a friend, I composed a fairly large list of parts to order from hobby stores. One of the initial components of R/C is power. How will it be supplied to your R/C craft? What types of batteries will you use? How are you going to charge these batteries? Instead of trying to get into R/C on a budget, I decided to spend a bit more than I wanted so I wouldn't have to upgrade to new and higher quality equipment later on. In doing so, I purchased a Turnigy Accucel-8 150 Watt 7 Amp Balancer/Charger. This specific charger needs to be supplied with 12 volts and it will do the rest; balancing and discharging the batteries to keep them in perfect condition. There are 12 volt power supplies available but I decided to go the DIY route, save a little money, and have a fun afternoon project.

Rooting my Galaxy S4

    When I originally purchased my S4 almost two months ago, one of the first thing I did was root it. There was a very [easy method] but a recent update from build version VRUAMDK to VRUAME7 wiped out the root access. After a few weeks, a new root method was found. I followed [this guide] on xda-developers.com and I was able to regain root access. Here's what I did:
