LabJack and educational programs

Submitted by LabJack Support on Tue, 06/16/2015 - 16:16

LabJack recently donated a few U3s to Stern MASS High School in LA, California, and their setup is a good example of how data acquisition hardware can be used in the classroom. Professor Peter Halverson organized a wonderful electronics lab for his STEM students, which they use to learn about programming, hard-core electrical engineering, and realistic scientific experimentation.

U3 experimentation fixtures on desks

16 experimentation setups, so students form pairs of 2 for the projects.

New Java LJUD Wrapper and Examples for the Windows UD Library

Submitted by LabJack Support on Tue, 06/16/2015 - 14:06

Now available for download is the new Java LJUD wrapper and examples for the Windows UD library (LabJack U3, U6 and UE9 driver). Using JNA it provides 32 and 64-bit Java support. This replaces the old Java LJUD wrapper which used a JNI dll and only supported 32-bit Java. For full details refer to the Java LJUD download's README.txt file.

Here is a simple code demonstration to read the voltage from AIN1 on the U6 ...

Improvements to Digit Firmware and Software

Submitted by LabJack Support on Tue, 02/03/2015 - 21:37

We released new firmware and software for the Digit-TL/H series data loggers which has some nice improvements.

New zoom tools. Starting in Otero version 1.53, there is a tool which enables zoom selection, zoom in on point, zoom extent, and a few other options to help users view their data.
Starting in firmware version 1.21, the Digit-TL/H recovers from replacing the battery, without having to re-connect it to the computer to begin a new logging session. When the new battery is inserted, firmware will remember where it left off, and continue logging data. The downloaded data will contain a flag indicating when the power failure occurred. You can see this feature in action if you set the log interval to 10s, let it log a few data points, then un-plug the battery for a minute or two, and plug the battery back in, and then download the data.
Non-critical settings are auto-saved. That is, it's not necessary to begin a new logging session when only settings such as the Device Name are changed.

Kipling received a version number increment to put it inline with our latest (windows only) version of Kipling that is released in our main installer and is considered to be in a public beta phase. This version of Kipling may have a few bugs, however it is a big improvement to the currently distributed version of Kipling and is recommended to almost all customers using a T7/T7-Pro.

More information about Kipling and how to get the latest version can be found on the Kipling Support page.

Digit with replaceable CR1632 battery!

Submitted by LabJack Support on Fri, 02/07/2014 - 18:19

The popular Digit-(TL/THL) series loggers now has a replaceable CR1632 battery! Another key improvement is the addition of a clear plastic enclosure so that light readings can operate while inside. If customers prefer the rugged aluminum enclosure, it can be purchased as an add-on item. See the Digit-TL/TLH product page for more information.

1 Year in the pond - Digit-TL reliability test

Submitted by LabJack Support on Mon, 01/13/2014 - 17:11

When we first started selling Digit-TL devices, we decided to stow one outside under a rock, and another in the pond to see how they'd hold up. After 6 months we downloaded the results to verify operation, and everything looked good, so we threw them back out. Now, after a full year, they're still going strong. See the data and photos below.

Each day is a small spike, and the yearly trend is shown by the overall shape of the graph. The two curves on the graph demonstrate how the water acts as a thermal buffer by regulating fluctuations in daily temperature. If you look carefully, you can tell when there is snow covering the Digit-TL on land, because the temperature fluctuation is minimal (like the Digit-TL in the water).
