In my iOS app I implemented a slide menu for easy navigation.

This blog post is written because of the LITEC LEDs.

I may, or may not, have "borrowed" some to be used in this project.

While I was setting up the LED, I tried measuring the characteristics of the LED using a multi-meter because LITEC doesn't have any datasheets for these LEDs that I know of currently.

More accurate data will be provided once I get it, but I noticed from my testing that: Forward voltage was equal to 2.1 V Forward current was equal to 10 mA

Which means that the ideal resistor connected for the LED is 290 Ohms at 5 V.

This was, by no means, a rigorous test, but it was the best analysis that I could do at that point in time.

The Auduino project itself came from my (mis)adventures during Hack RPI 2014.

I wanted to use the Arduino to create some type of project where I could send data from my laptop to the Arduino and have it spit out relevant information using a TFT color screen. At first, I tried to code PONG using C#. Unfortunately, there seems to be some type of bug in C# that somehow skips code at the most inopportune moments (i.e. when the ball is supposed to bounce away from the bottom of the screen.)

This bug was so frequent, yet random that I simply gave up on the idea out of frustration.

Near me, a friend of mine (who I will name if he wants me to) wanted to do an audio project for his Raspberry Pi. (I can't really remember the specifics of the project.)

After putting two and two together and asking this friend for some spare hardware, I made a simple project that sends data through serial to the Arduino and have that Arduino react to the data.

This project will definitely not be some full-scale project that leads to groundbreaking progress. This will be more of an exploratory project to see how to solve problems involving the Arduino, serial communication, and audio data. If this project doesn't change the world, at the very least, I can change how I see the world.

This project kinda goes with the theme of "I want to make this project because it interests me and I think I'll use it" projects that I have seemingly been chasing around.

This project involves music/sound and hardware, two of the things that I love the most.

Here's to a brand new start and another development project!

The program currently monitors CPU, Memory, Network, and Disk I/O usage. It graphs this data based on user input using WPF (Windows Presentation Foundation). We've also implemented python scripting for custom monitoring. One of the biggest enhancements we've developed is background monitoring. The user can have Check Up run in the background and it logs the data it collects to a .csv file so the user can later analyze, graph, or use the data for whatever he/she may need to. This program utilizes the .NET framework performance counters so it uses 0% CPU while running in the background after the initial CPU load of loading the performance counters.

Currently, the background monitoring only logs information about specific processes. In the future we hope to implement OS level monitoring in the background. Another addition we hope to implement is an even better looking GUI. Since we started using WPF, the GUI has definitely improved a lot, but adding Custom skins/color palettes could take that to the next level. Lastly, we'd like to make some performance improvements during the loading screen. Currently it takes around 10 seconds to load the performance counters so we want to find a way to cut down on that time.
