CINs are out, Call Library Function Nodes are in!

Two months ago we documented how to create and use Code Interface Nodes (CINs) for LabVIEW on Mac OS X and Linux. It’s a great way to call C code that uses the Exodriver, but we discovered that LabVIEW 2010 does not support CINs.

LabJack Bartender Phase 3

Mounting Stand and Circuity Complete


On the left is the 24V power supply, in the middle is the U3, and on the right lies the power switching circuit designed during "Phase 2" of this project. 

The mounting stand is comprised of 5/8" threaded rod situated in a PVC base.  There are large threaded nuts at the start of the PVC to allow for height adjustment. 

The solenoid valves are all wired into the power switching circuit, which is controlled through the EIO, CIO, and FIO lines on the U3. Using a python script running on a local PC the valves are opened and closed. The next step is to buy a bunch of alcohol and connect the piping.
