Raindrop VI

NI engineer Christian Lowe created this simple and fun VI that simulats rain drops rippling across a surface wherever the mouse is clicked.  Download it today!


This example VI is a variant on the old Tic Tac Toe game and includes low level computer intelligence to allow you to play against yourself or a friend.


Download this flight simulator VI library from community member Torbjorn Tjellden. His code is based on his 3D-script viewer, which has three inputs: the script with leaves and variable names, the definition of leaves, and the variable array.  For the airplane, those variables control the wing, flaps, roll, etc.  Torbjorn is currently working on an editor for the landscape and additional features.  Visit this wiki collaborate on his code, comment on the functionality, or just have some fun.


LabVIEW - Snap to It

Posted by Deirdre Walsh May 2, 2008

  Download Mark Ridgley's SnapToPanel VI, which allows LabVIEW developers to position a target VI window relative to a reference VI window. Click here to get the code or comment on the functionality. 



Check out this cool YouTube video from NI AE Evan Dozier. He found an old robotic arm with a broken controller and revamped it using NI hardware, LabVIEW and the Nintendo Wiimote.  Evan uses special Bluetooth LabVIEW VIs to control the robot. 


Visit the VI Roadshow  video blog for more zany applications.

Almost everyone using LabVIEW understands that a wire carries its data type as well as its data. What many people do not seem to know is that there is an easy interface to view the data type (other than the color and shape of the wire, which are only indicative up to a certain level). This interface is the context help window, most easily opened by pressing Ctrl+H or clicking the yellow question mark near the VI's icon.  Look at the following image. See how hovering the cursor over different wires shows the information about the wire. This information includes the type and name of the wire. The name is determined by the source of the data.
