Liberty University Jerry Falwell Library Tour

Posted by Nathan House, 25 October 2013 · 3,561 views

Liberty University is building a new $50M library and the Liberty University Robotics Club had the opportunity to tour the new library and see it's robotic book retrieval system today.

I forgot to bring a camera and used my cell to take the pictures and video below, so they're not the best quality, but hopefully you get the idea of how cool it was!

Arduino maze solving robot

Posted by Nathan House, in Completed Projects 04 October 2013 · 7,682 views

Last semester my robotic's club's goal was to build small robots that could navigate through mazes. I was able to complete the challenge, but I just realized I never posted about it on here!

Averaging HC-SR04 ultrasonic distance sensor readings in a non-blocking manner

Posted by Nathan House, in Programming 08 July 2013 · 2,575 views

This is a reply to a facebook post. It would have been difficult to read in facebook's narrow layout, so I'm posting it here.

In order to average three readings from a sensor in a non-blocking manner, you could either have three variables like this:int ultrasonicReading0 = 0;int ultrasonicReading1 = 0;int ultrasonicReading2 = 0;
A variable to store the...


Measuring RPMs with Arduino

Posted by Nathan House, in Programming, Electronics 12 June 2013 · 7,833 views

I was asked whether an Arduino would be capable of measuring a device that is rotating at 100,000 RPM. Assuming that there is 1 interrupt per rotation, that gives us the following:

100k\:rpm = \frac{100k}{60} \frac{rotations}{sec}

Therefore, \frac{60}{100k} \frac{sec}{rotation}

So the period is \frac{60}{100k} sec and the frequency = \frac{1}{\frac{...


Why I no longer buy books at Barnes & Noble

Posted by Nathan House, in Books 24 February 2013 · 1,705 views

Bookstores have a special place in my heart. I love the atmosphere, the smell of thousands of books, and the opportunity to peruse the literature. But despite that, I no longer purchase books from my local Barnes & Noble. I still go to the store every once and a while - as I said, I love the atmosphere - but I no longer buy anything, except perhaps fr...


Looking back - a year without TV

Posted by Nathan House, 26 December 2012 · 3,264 views

On January 1st I will have gone one year without watching a single television show or movie. In anticipation of this landmark, I thought Iā€™d write why I did it and reflect on what a TV free year ā€“ something many people will never experience ā€“ was like.


Why I did it

Most people will admit that TV is overall a bad influence and a waste of time, but tha...


Notepad++ FAIL

Posted by Nathan House, 17 March 2012 · 2,536 views

I've used Notepad++ for several years now and have yet to find it's equal. Sure, there are full blown PHP IDEs available, but those are more advanced than what I need and are slow. Notepad++ is very lightweight and starts up almost instantly, has great syntax highlighting, and works for many different languages. In short, it's great. Today however, it fai...

I recently purchased a My Weigh iBALANCE 601 precision scale for measurements and parts counting. This scale rocks so hard, I just had to write a short review.!

Small things in big packages

Posted by Nathan House, 13 February 2012 · 2,759 views

There's a saying, "Big things come in small packages." So, what comes in big packages? Small things of little value, of course. Take this package I received, for example:

A fairly large package, right? I wonder what could be...
