JMRI CONTRIBUTIONS
Although I have done none of the programming for JMRI, I have been a long time user and have made some contributions that can be enjoyed by others.

If you need to find icon resources, check out the pictorial directory I created.  Bob Jacobsen has indexed the directories to show the icons in your favorite browser.
While developing my CTC panels, I created several icons which are now part of the JMRI distribution.  These include the US&S plate, a knockout plug
and a set of wide Red lampsignal levers.  These include a bigger transparent background that is easier to use with a touch screen monitor, mouse or trackball.


In 2006, I did a JMRI clinic at the Philadelphia NMRA National  Convention.  I showed some of the developers the 3 position signal lever I concocted using a pair of "ghost sensors" and the three lever icons.  I needed three positions.  One of the developers took the concept and created the multi sensor icon groups we all can easily use today.

In 2012, I created a JMRI panel tutorial.  This can help guide a new user through the creation of panels using Layout Editor and Panel Editor.

JMRI Panel Tutorial



The set of three pdf files in the tutorial show you step by step how to construct the two panels shown at left and also the Logix to control them. After completing the tutorial you should be equipped to develop similar panels for your own layout.

Virtual signals on a tablet or smart phone



Most recently, I documented the use of virtual signals using the JMRI and Engine Driver technology in an article in the June 2015 Model Railroad Hobbyist online magazine.  I also describe it on the QV web site

Each of these ideas piggy backs on the work of the real developers.  Kudos to all.
