Here is a list of all the basic NI TestStand documents I can find online. I attended this TestStand 3hr. course a few times. It's only useful if you do all the exercises in the book, then try making your own.

I just found an excellent way to invest money and receive more than a bank could ever offer as interest.
Have you ever felt jealous of the credit card companies that charge over 10% to their customers. Imagine if you could invest money like a credit card company. Imagine if you could choose who gets your money based on their credit history. And you can limit how much you invest in each person, usually only $25.
Now you can by signing up with Lending Club and find out how to invest like a credit card company.
You can also get a loan at Lending Club. Request a loan today and you can get funded in just a few days from people who joined Lending Club for the investment.
This new combination of people with money to invest by loaning it to people in need is called P2P Lending (peer to peer). Several investors pool their money together and loan it to one person. No one invests all their money in one person, usually your money is spread out with multiple loans each earning you interest. You can also sell your positions in the loan if the persons credit history starts to go negative.
Lending Club respects the privacy of its members. Your personal information, whether you borrow or invest will always be kept totally confidential from other members -- including me.

Here is my latest video. It's an overview of National Instruments TestStand test automation software used with LabVIEW to create a PCB testing system.
This video shows how easy TestStand and LabVIEW can be used to create a powerful test automation platform.
I couldn't find a lot of information on how to start using NI TestStand and LabVIEW together to create a PCB test sequence program.
I knew it was easy to do but I didn't realize it was this easy to get started. After one afternoon playing I was able to do this video.
My next video will be a little more advanced.

I attended my first day of NIWEEK.
It was lot's of fun. I registered my attendance first thing in the morning and the lady accidently gave me a Certified Developer tag for my badge. So I was a CLD for only a day. It was my lucky day. Hopefully it's a sign of the future. Maybe I will truly be a CLD soon.
I attended a LabVIEW seminar on file management in the morning after the keynote speeches.
I skipped lunch and walked around the Exhibit Hall to see all the neat things people have created using LabVIEW and NI products.

Here was one of those tricking CLAD questions that I've never come across until I was taking the test.
The question was like this example:
If this vi was run, what would the output be?
At first glance it looks easy. With the selector terminal input being 'clad' and the case selector label being Clad, it should run the one button dialog box and print "This
is Clad". But look again. The string input to the case structure is
lowercase "clad". Yes the case structure IS CASE SENSITIVE.
When I hit run on this vi, it doesn't recognize the "clad" and runs the
default case instead.
Here is what it looks like when I correct the lower case string input.
By correcting the string input to "Clad", it now matches the wording and case of the case structure and runs the "Clad" case which gives the one button dialog box output of "This is Clad".
Yes, the case structure IS case sensitive. Try it before you take the CLAD test.

I just received a wonderful device that defies logic. I now have a Kindle Keyboard 3G, Free 3G + Wi-Fi, 6" E Ink Display - includes Special Offers & Sponsored Screensavers
The reason it defies logic is because it has FREE 3G. Who provides FREE 3G these days? That's unheard of...
This Kindle Keyboard is so awesome. Sure it's black and white and a little slow, but did I mention it has a web browser and FREE 3G. That means I can check email anywhere without paying for the airtime. I can check my Yahoo and Gmail. I can read TheDrudgereport.com, Wikipedia, update my Facebook and Twitter and anything in real time from anywhere without a charge. This just blows my mind. Here is a pic of this website on the Kindle Keyboard..

I just passed the CLAD LabVIEW certification exam. It was a bit tricky. I studied everything I could find.
In my opinion, the test consisted of half of the standard questions you find on the online practice exams. The other 50% I have never seen before except for in the Core 1,2, and 3 classroom exercises.
It was 40 multiple choice questions. I finished in less than 30 minutes and used the rest of the time to review my answers.
My advice to anyone taking this test is to study the practice exams, but also methodically go through all the exercises of the Core 1 through 3 classes. If I would have reviewed those examples in the classroom exercise book, it would have greatly improved my final score.
For those who have not taken Core 1 through 3, I'll try to give a few examples in the next few weeks.
Stay tuned.

Just like a programmer starts off printing "HELLO WORLD" on the screen, in LabVIEW you can start off by learning to count to three. It's not easy or intuitive to find a way to count between two numbers. The key words are "Quotient & Remainder." On the Block Diagram hit CTRL and then SPACEBAR at the same time to pull up the Quick Drop dialog box. Type in Quotient & Remainder. It should find it by just typing in Quo....
Now add a While Loop around the Quotient & Remainder.
We will use the iteration (i) terminal from the while loop to show the current loop count. The iteration terminal starts with zero on the first sequence. We connect a wire from the iteration (i) terminal to the X input of the Quotient& Remainder.
We need to add an upper limit number to the Y input of the Quotient & Remainder. So Right-Click your mouse over the Y input and Create a Constant. We want this vi to count from 0 to 3. Put a 4 in the constant box. The output will count from 0 to 3 because the first count will be the zero and the fourth count will be the number 3.
Right-click on the upper right output connector of the Quotient & Remainder and create an Indicator. This numeric indicator will be shown on the Front Panel. This is where the numbers will be seen. If you want to use this number for another operation, just add a wire and connect to another vi, or a graph, etc.
You will need to add a Stop button to the front panel for this example and wire it to the Stop if True function of the While Loop at the lower right hand corner. Let's also slow it down a little so we can see the operation working. Add a Wait Until Next ms Multiple icon with 500 as a constant wait time.
Hit run and watch the numeric indicator count from 0 to 3 on the Front Panel. Hit the Stop button to end the process.
Thanks for learning how to Count To Three using LabVIEW with me. Feel free to leave a comment.

Scrape or retrieve data from a website using LabVIEW. This is also called data harvesting or data extraction from websites.
One difficulty is finding good HTML data to scrape. Most data like stock quotes have been replaced with dynamic data that doesn't have a clear and consistent text strings that can be searched.
Here is an example that opens a URL website, reads the HTML, picks out a string keyword and displays the data after that keyword. I've chosen a weather site that has a consistent keyword like "temp"> and the page is dedicated to only one city. So the number after "temp"> will be that city's temperature.
This vi will be great for any instrument attached to a network with a web-page to access.

LabVIEW Web UI Builder is a Web-Based LabVIEW programming Environment that gives you the ability to develop lightweight VI's without needing to purchase LabVIEW.
Practice creating and programming VI's now. Try It Now Create your account to start programming with LabVIEW.
LabVIEW Web UI Builder is free to try out for an unlimited amount of time. Anyone can create an account and develop an application that runs inside the editor. Users can save their work to cloud storage or, if the editor is installed locally, to a local hard drive. The only feature that is not available for free is the ability to build and deploy standalone web applications that no longer require the editor.
I loaded it on my computer and tried it out… It’s awkward to use but it works.
Here are some screen prints and the example vi…

So you've completed STEP #1 Get LabVIEW and you've worked through the examples given in the tutorials. Then you followed STEP #2 Get an Arduino. You checked out your Arduino and now you are ready to program the LIFA files onto the Arduino with STEP #3 Load LIFA.
You need some way to test that everything is connected and working. You also need to get familiar with both LabVIEW and Arduino together.
Your first LabVIEW project needs to be something very simple and easy to understand. Most programming languages and starter circuits always have a "HELLO WORLD" to learn from.
Controlling an LED with an on-screen switch would be an easy way you can interface the on-screen controls of the LabVIEW Front Panel with the real-world LED connected to an output of the Arduino.
You can start by adding a switch, a stop button and an indicator LED to your first front panel. You can also add these items from the Block Diagram.

The Block Diagram shows the connection details of my Arduino Clone. Your settings may very depending on what Arduino device you have connected. You can always find the com port in your control panel, Hardware manager of Windows. Plug your Arduino into the USB jack and see what com port is listed when it connects.
LabVIEW has a free 30-day evaluation copy you can download at National Instruments or you can purchase the LabVIEW 2009 Student Edition
Once you install LabVIEW on your computer, you can go through the "Getting Started with LabVIEW" tutorials which help you get familiar with the inner workings of LabVIEW. You can learn how to convert degrees C to F by using only mathematical terms and the front panel controls. I've seen on YouTube video on building a calculator using LabVIEW. It's a bit long and tedious to build but it's a valuable learning experience if you work through it.
