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 signal 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.
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.

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.
