Isn't this the same timer as on miscjunk.org?

Yes, this is the same timer, resources and person behind miscjunk.org timer. I am moving all of the miscjunk.org content to this website.

Can the Adafruit 1.2" displays be used with the PDT?

Yes, with a little extra work they can be used.  Please refer to Timer Construction page for more information.

When compiling the sketch (after installing the Adafruit libraries) I get errors about an 'ArduinoRobot'.

This is an old issue from when the Adafruit libraries were installed manually.  Current versions of the Arduino IDE have a library manager to handle library installs and this should not be an issue.

This is caused by a conflict between different versions of the Adafruit libraries.  The simplest solution is to delete (or move) the Robot_Motor and Robot_Control directories out of the libraries directory.

The PDT3 program (or one of the windows) is stuck minimized.  The lane place/time display is small and will not resize.

Hold the Ctrl key down while opening the main program (or the window).  This will force the program (window) to open normally, discarding the previous size and position.
