| (...) I have been working on a different project toward the same end-- improved train layout automation, and I have had similar questions as to whether it is worth the effort for the small number of people who might actually benefit from it. Since (...) (22 years ago, 21-Nov-03, to lugnet.trains, lugnet.robotics.rcx.pbforth, FTX)

| (...) Dave, don't take ALL the fun out of driving your trains :-) How about being able to focus on just one train that you control, but automate things so the OTHER trains don't hit yours? Your description was great, except that it involves MANY (...) (22 years ago, 21-Nov-03, to lugnet.trains, lugnet.robotics.rcx.pbforth)

| (...) Actually, this is a common misconception. In Java, there is no guarantee that memory is _ever_ reclaimed. It is perfectly permissible by the specification (and quite common in embedded applications) that garbage collection is _never_ done. At (...) (22 years ago, 21-Nov-03, to lugnet.robotics)

|
| Hi all! I am not in to lego robotics myself, but I want to share this: At the Robotex 2003 ((URL) ) competion, the winner was the Lego robot. I did not follow the show that much, but I did notice how efficient the Lego robot was, how fast it found (...) (22 years ago, 21-Nov-03, to lugnet.robotics, lugnet.general, lugnet.mediawatch)
| | | | | Trains, DCC, and pbForth
|
| All, As I've mentioned before, I have a version of pbForth firmware for the RCX that allows you to control trains modified with DCC controllers. The benefit of pbForth is that you can write, test, and debug your application interactively using (...) (22 years ago, 21-Nov-03, to lugnet.trains, lugnet.robotics.rcx.pbforth)
