A Cheap but Quality Home Surveillance System

Today as I got into my car I realized that someone had broken into it and ransacked my glovebox and center console. I couldn’t nail down exactly when it happened but I couldn’t help but feel violated.  Someone else in my neighborhood also had a break in. I decided to do something about it. I immediately went to the closest store and grabbed a cheap webcam and prepared to make a motion triggered surveillance system. (Man, I love Linux).

20-ish Must-Have Astronomy Android Apps

I’ve recently gotten into astronomy and astrophotography since I got an 8″ telescope for my birthday in 2010.  Since then I have found that my Android phone is a must have tool! This is a list my favorite and most useful Android apps for astronomy. All of the ones mentioned here are free or have a free version. I suggest donating or upgrading on all of them if you like them to help compensate the programmers for their hard work.

UPDATED with new app (see end of post for the new addition).

First Weather Balloon Launch Video and Google Earth File (Pt. 2)

With the payload tested in a rocket, everything looked ready to go. I took it off the breadboard and built it onto a strip board PCB to make everything sturdy.

The next step was to create the payload box. The professor had done this before so he gave us tips on using foam core poster board, hot glue and HVAC tape. We chose to cover ours in mylar by applying a spray adhesive to the surface, then laying a sheet of mylar on it, and using credit cards to squeegee it flat as best as possible. The mylar was applied to the insides of the box before gluing, and the outside afterward.

First Weather Balloon Payload Testing on a Model Rocket (Pt.1)

Working with a professor at my college and Carolina Edge of Space in May of 2010 I, along with a small group of friends, sent a weather balloon 74,642 feet into the sky.  This post is mainly about the payload I designed, built and tested for the project.

This project was inspired by many seen recently online where students have been sending cheap payloads into the stratosphere. It started around December 2009 when we all met for the first time to discuss the project. It turns out that one of the professors in the Earth Sciences department focuses on remote sensing (gathering data about earth from satellites, etc.) who had done some weather balloon projects in the past. We all got together to discuss a possible launch.

How to Replace XP with Linux

Many people are curious about linux, or maybe have even tried linux at some point. There is a huge difference between people trying linux, and people using linux. Hopefully this article will sort of ease your transition into using linux, either as a full time OS or even just enough to get around if you ever encounter it. Once you are familiar with software on one OS, its tough to move on but with this article I hope to list out some linux software that replaces many of the XP programs I once loved and how to run certain irreplaceable Windows software on linux.

The version of linux used here is Linux Mint, which is built off Ubuntu.
