Build Video: Digital Oscilloscope DIY Kit

Why am I covering Arduino Here?

I have some exciting projects coming up that involve Arduino and BlackBerry and in order to make those happen, I need to help show you how Arduino works first!

About the Kit:

For those of you who know me, I recently ordered a large shipment of PCB boards from a company some of you may have heard called SparkFun. Besides getting a whole bunch of cool boards, I made one additional unnecessary purchase: A DIY Digital Oscilloscope Kit.

See the assembly video here.

My rating: Medium Difficulty - Not for Beginners, and 5/5 for Fun!


JavaScript Functions and Preserving Data

Cascades is a framework built on top of Qt, a C++ application framework. Qt allows for fantastic user interfaces with a custom language based on JavaScript called QML, or Qt Modeling Language. Not only is QML based on the structure of JavaScript, but it allows us to use JavaScript in our code.

Coming from a web design background, I have almost ZERO experience with C++. I'm not saying it's difficult to use or challenging, I'm just personally not use to it. When I learned that I can opt for JavaScript to do simple functions instead of C++ I was ecstatic, I just wasn't sure where to start.

In this tutorial I'm going to walk you through making a random number generator using some JavaScript MATH functions as well as creating our own.


Building an Arduino Temperature Sensor with an LCD Display


As part of my learning curve for open source hardware, and basic electronics.  This project wont take you very long, maybe an hour at most.

What this does is pretty straight forward, it shows the temperature in real time for both Celsius and Fahrenheit.  I’ve added some code to the Nokia, which uses the analogWrite trick (that is, use one of the digital outputs that has a tilde in front of it ( ~ ).  This will let you send a modulating frequency, which means you can make the LED (backlight in this case) brighter and dimmer.  The brightness of this display is controlled using the trimpot (potentiometer).


MockIt! Beta 2: Some Statistics and Release Notes

Recently, the Beta 2 version of MockIt! was released in BlackBerry BetaZone. With this release I was able to implement the most requested features and fixes and refine the UI/UX. Since its release, Beta 2 has been downloaded over 7,000 times by over 5,000 unique BlackBerry IDs. Moreover, over 14,300 testers have enrolled in the MockIt! beta program since launch, and MockIt! (all versions) has been downloaded a grand total of 28,000 times.  Keep reading for all the changes and some details regarding the roadmap.


Meggy Jr RGB

Recently, a friend introduced me to Arduino.  Rather, he’s been trying to introduce me for a while and I’ve just been too darned busy to play with it. 

So, I took on some projects and spent some energy on it this last month.  As a result, I have a handful of posts coming up about open source hardware :)

First up, Meggy Jr from evil mad scientist.

Not really an arduino, it was a great way to warm back up to soldering and electronics.  The entire kit took about two hours to assemble, and requires some hand tools as outlined in the manual.  I went ahead and picked up a tool kit from SparkFun as my old soldering iron has seen better days – which is another interesting (albiet expensive) electronics company I have purchased from in the past.

At the same time, I also purchased an Arduino Esplora + TFT from CanadaRobotix – but more on that later.
