The writing's on the (water) wall: this week's LabVIEW demo unites art and science, and it is a match made in heaven. Imagine shimmering sprays of water against a backdrop of colorful light. With just the click of a mouse, the streams speed up, slow down, spell out names, trace intricate patterns, and draw beautiful things like hearts, smiling faces, and the initials NI. The engineers at Optimation Technology designed this über cool writing waterfall for trade shows and conferences, and it's currently making a splashy appearance at NIWeek 2011.


The waterfall uses NI CompactRIO (cRIO-9073), and its user interface was written with NI LabVIEW software. The power of LabVIEW allows its user to transform input data into liquid art by simply drawing his cursor on the computer interface. CompactRIO has much more capacity than the current application requires, so the team has a ton of room for future innovations. If you're currently at NIWeek, be sure to check out this cool demo in the Embedded Control Product Showcase on the NIWeek expo floor!

NI has announced new 1-slot NI CompactDAQ chassis that support wireless, USB and Ethernet buses, giving you the portability of a data logger with the performance and flexibility of modular measurements. The new chassis support all NI C Series Modules for NI CompactDAQ and can be used in conjunction with the existing 4- and 8-slot chassis.




New metal enclosures make the chassis more resistant to environmental damage as compared to the previous plastic sleeves. The chassis operate in a temperature range of 0 to 55 degrees Celsius and can withstand up to 30 g shock and 3 g vibration.


More than 50 measurement-specific modules featuring multiple electrical and sensor connectivity options can be combined with any chassis to create customized systems. NI Signal Streaming technology delivers high-bandwidth capabilities for achieving sustained high-speed and bidirectional data streams over USB, Ethernet and wireless buses. Zero configuration networking technology simplifies initial setup, eliminating the need for IT involvement in network setup and integration.


Each NI CompactDAQ chassis includes NI-DAQmx software to help you log data for simple experiments or develop a complete test system in NI LabVIEW, NI LabWindows/CVI, ANSI C/C++ or Microsoft Visual Studio .NET.

I am having trouble reading multiple analog inputs through an Arduino. It seems like the signals are leaking into eachother. I get very similar readings across each each of the pins and readouts.
