  1. pbForth MazeWalker on Fun with LEGO Mindstorms Programming · · Score: 1

    I've got a number of comments ranging from "what a stupid idea it is to eliminate cross-platform issues by compiling right on the brick" to "what a great idea it is to eliminate cross-platform issues by compiling right on the brick" Now I don't know what to think anymore...

    Here's a real pbForth application. It's a robot that navigates mazes drawn on paper. No, it's not on wheels, it's really a gantry crane, but it's something that the standard Mindstorms firmware can't do...

    Have fun...

  2. Re:Mindstorms™ is sort of limiting on Fun with LEGO Mindstorms Programming · · Score: 2

    Well, as Markus Noga, author of legOS said during our "Extreme Mindstoms" panel discussion at MindFest 1999, "Form is liberating"

    What he meant was that within the bounds of a fixed set of parts and capabilities, the challenge is to do some thing useful with the exisiting parts, not to wish for parts to build bigger things.

    Just about every LEGO enthusiast goes through a bulk acquisition mode, where the goal is to get as many parts as possible. The resulting time spent sorting severely limits building time :-)

    Check out my pbForth MazeWalker for a bot you can build with just the parts in RIS 1.0 - well I added two rotation sensors and two micromotors, but you could also use touch sensors as shown in Mario Ferrari's TicTacToe Robot

    Have fun...

  3. Re:purple noon on Holiday Movie Thread · · Score: 1

    Yes, I happen to have watched the movie recently on video, and was not sure what was going on until - well, the middle anyways. It's interesting because it is one of Martin Scorcese's first movies, I think. The production values are cheap compared with today's movies, and the colours are somehow washed out, but it has the real feeling of coastal Italy. Go figure, it was filmed there. I am in no rush to see the new release since it looks like another pathetic Hollywood ripoff of an interesting idea which was well-done in the 60's and has the addition of pretty faces and gore for the 90's Cheers
