(...) No, it's way simpler than that. The text files on the Palm are source code for Quartus Forth on the Palm. The idea is that the *same* source gets sent to the RCX via the IR link - you can do it now with a serial link, a terminal emulator, and (...)

(...) Well, actually, the idea was to be able to write Forth source on the Palm and upload it using a terminal emulator from the Palm. If we can integrate the IR into Quartus Forth, then it would indeed be cool to upload firmwarwe and code from the (...) (24 years ago, 7-Feb-01, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

(...) The light sensor doesn't actually "see" colors, it only distiguishes between dark and light. Therefore I have found that using different grey scales is a good way to make distinguishable "colors". Different grey scales can be made by printing (...)

(...) My card reader 2 reliably reads cards built with yellow, grey and black plates ((URL) problem in brick sorters is that slight modifications of brick positions can cause more variation in reflected light than color.

|

I'm a not an electrical engineer and I couldn't even play one on TV : Ok. That being said, would it be possible to amplify the PWM output from the RCX to run multiple (2-4) motors off a single output connector using an external nicad battery ? Can (...)

Just a thought: Couldn't one make a "rosetta stone" wheel of the various LEGO(R) colors that uses an angle sensor for indexing them and then just compare the brick being "measured" to the known bricks on the wheel ? It'd be cumbersome, but not very (...) (24 years ago, 7-Feb-01, to lugnet.robotics.rcx)
