LabVIEW Example For Younger Crowd.

Hello,
I am giving a presentation for a group of younger kids this friday, June 29th and I need a LabVIEW example that I can show them and talk about. So I need something that younger kids, ages 5-13 can understand. Its ok if its too boring for the older kids and too confusing for the younger and vise versa. I can adjust how I talk to compensate. So far I have a bouncing cube demo, but that is not complex enough to talk about for a length of time. I would also like the example to relate to engineering as much as possible and is not just a game like Tic Tac Toe. Thank you for your suggestions.

It is always good to do something where the students can be involved during execution. For example you could fill two parallel tanks with random numbers and take bets which one fills first. (learn about loops, shift registers, comparison (see if it is full), decision, etc.)
You might also do some real DAQ with the soundcard. Again do a "race" where the two tanks fill according to sound volume. Do a FFT and tie one to the high frequency (girls!) and one to a lower frequency (boys!) and let the class scream their heart out to advance each tank/slider.
Other soundcard things would be a simple voice scrambler or changer (doesn't work that well without RT). SImply record some sentences, do some digital signal processing, then play it back. See how the sound changes depending on settings (double/half the frequency, low-pass, hi-pass, etc.)
If you have more time, you could also e.g. test batteries and see what brand is best. See:

Labview example for data capture using 5102 scope card

How can I program a Labview Vi to control, and capture a waveform using the 5102 scope card. I need to be able to set it up to continually capture a waveform (Channel 1 and Channel 2) when triggered on a rising edge of channel 1 and then store the data on disk automatically, then wait for the next trigger.
Any help or tips as to how I could do it would be helpful.
Thanks
Allan

Allan,

Where can I get LabView examples for PXI-6551 or 6552? Thanks

We are thinking of buying a 655x and wanted to see sample code to get an idea of its capabilities.
Does anyone know where I could find LabView examples?
Any other information related to the PXI-655x would be appreciated too!
Thanks,
-KP

Hi KP,
Thanks for your interest in the NI 655X. These products use a brand new driver, NI-HSDIO, which is based on DAQmx. We are still working on a more bandwidth-efficient web installer for the driver, but for now I have placed it on our temporary ftp site. You can find it at ftp://ftp.ni.com/incoming/HSDIO.zip
This driver contains a full set of example programs for both LabVIEW and CVI, and the help files are a great way to learn about the physical capability of the board.
Do you have any other questions about these products?

Labview examples for an "http transponder"

I’m looking for Labview examples (LabView 5.1 or 6i) to make an “http transponder” between an intranet and internet networks.
I’ve a “system” configured with a TCP-IP address in the local intranet network, it isn’t a PC but its behaviour is like a local “web server” without external access, so it is possible to send it URLs from an every PC (with internet explorer) inside the local network, to get the “system” status.
I’d like to monitor that “system” in the internet network also, so I need to make an “http transponder” on a PC connected in the local intranet network, but with external access permission.
So it can be possible to s
end URLs to the transponder by a PC in the internet network, and the transponder can redirect them to the “system” in the intranet area.
The “system” can send his status along the inverse route.
Thank you in advance.
Natalino.

Thank you, it would be useful, but I haven't an "Internet Toolkit" at the moment.
I made some attempts with low level Tcp-ip functions, and I obtained good results by loading static html pages, bad ones by loading dynamic pages.
I think is an integration problem (timeout, waiting times, etc..), so some "previously tested" examples with Tcp-ip function would be very useful.

Looking for Labview Examples for At-MIO-16DE-10 and AMUX-64T

looking for examples to record:
Load vs strain and temperature using these two.
Also a quick guide to how to get started. I hav Labview 6i and the card and board. No experience yet.

Greetings,
There are a variety of documents on our website that contain information about using the AMUX-64T with an MIO device. There are also example programs that show how to acquire readings using an MIO device with the AMUX-64T. I have linked to some of better documents below as well as the AT-MIO-16DE-10 and AMUX-64T User Manuals.

http://digital.ni.com/public.nsf/websearch/9D8232DFFE50108F86256DCD005A319B?OpenDocument
I would start with making sure the AT-MIO-16DE-10 is installed and configured correctly. You can used Measurement and Automation Explorer (MAX), which is software that is installed with NI-DAQ, to configure and test the AT-MIO-16DE-10. The AT-MIO-16DE-10 user manual goes through the installation and configuration steps for the device. Then I would attach the AMUX-64T and try to acquire signals. You can use the AMUX-64T user manual and the other linked documents to help you determine how to acquire signals when the AMUX-64T is connected to the AT-MIO-16DE-10.
I hope this helps.

Hi Holger,
just take a look in the example finder in the folder
DAQmx/analogin/Acq&Graph Voltage-Int Clk-Dig Ref.vi.
This answer asumes that you use DAQmx under LabVIEW 7.0 (or 7.1) for acquiring voltage.

Where can I find example LabVIEW VIs for the NI-USRP?

There are several sources of example LabVIEW VIs for the NI USRP:
We have established a NI Community "NI USRP Example LabVIEW VIs" where you can find example VIs from us (NI) and the community.
The NI-USRP driver installs a variety of example VIs to the to the following folder on your PC:
<LabVIEW Installation path>\examples\instr\niUSRP
where you should replace <LabVIEW Installation path> with the root folder of your local LabVIEW installation. For instance, my Windows 7 32-bit PC here has LabVIEW 2011 installed and the examples can be found here: C:\Program Files\National Instruments\LabVIEW 2011\examples\instr\niUSRP
I've installed the NI-USRP driver, but I can't seem to find the new examples in the LabVIEW Example Finder. Where are the example LabVIEW VIs installed by the NI-USRP driver?
Although the NI-USRP driver does indeed install examples, the current NI-USRP 1.1 release does not update the LabVIEW Example Finder with entries for these examples. To find the examples, you can navigate the Windows Start Menu to the following location:
Start Menu\Programs\National Instruments\NI-USRP\Examples
This Start Menu entry includes several Shortcuts that point to folders that are the home to example VIs.

Hello,
It looks like Agilent/HP makes the 8990A, but I was not able to find a driver for it that we or Agilent has written for this device.
Since I am not familiar with the 8990A, I cannot recommend which drivers might be similar, but you are pointed in the right direction. Agilent themselves might know more about which models use similar command sets so that you can modify a driver easily.
Hope this helps.

Examples for labview having sub vis

I am making some examples for labview adding to labview example directory (..\LabVIEW xxxx\examples\my own examples).
My examples contains some sub vis. As i copy example files and sub vis to (..\LabVIEW xxxx\examples\my own examples) then i see all files in example finder example files and sub vis. Is there any method that doesnot show sub vis in wxample finder. I will be very thank full to you NI. Sorry if i am duplicating post.
regards

I have a couple of thoughts about your questions:
1) When browsing by Directory, yes you will see subVIs. A common practice is to put all your subVIs in a separate folder labeled 'subVIs'. That way they don't look mixed among your examples.
2) Darren is correct that the bin3 file format is the same for all versions of LabVIEW, and that the bin3 file you created for LV 2010 will work in 2011. Notice he mentioned to put your bin3 file in [LabVIEW 20xx]\examples\exbins. This is important for LabVIEW 2011 and beyond. In LabVIEW 2010 and prior we would look anywhere in the examples folder for bin3 files. To speed up the launch time of the NI Example Finder, starting in LabVIEW 2011, you must put your bin3 file in the \examples\exbins, instr.lib, or user.lib folder. You can find this information if you click the Help button from within the Prepare Example VIs for NI Example Finder.

Where can I download LabVIEW example codes for NI PCI-6014

I bought an PCI-6014 DAQ device, please tell me where I can download the LabVIEW codes for this device.

Hi,
If you have labview package, you can find lot of examples there.
Start Labview -> Help Menu -> Find Examples-> Hardware input and output -> DAQ -> Here you either you can go to analog input -> then general -> search vi as per your requirement.
Or you can use timer/counter/digital input & output example vi from here.
Hope it helps. Your feedbacks are welcome.

Labview player for linux?

I have a Labview VI running on my Windows platform. I developed it using the Windows version of Labview 7.1. I used the Web Publishing tool to make the display available online. I have verified that I can see the display running in real time using IE on a Windows machine.
Other machines in our LAN are running Linux, and cannot view the site in real time. For example, Mozilla asks for a plugin, but I can not find Labview Player for Linux anywhere. Can anyone help me get the Linux machines to see the real time site that is being hosted from a Windows machine?
Thanks

I don't think that there is a plug-in for a linux system to be able to view the published LabVIEW front panel.
Wait! Try looking at this link:
