Also if the RCX is NOT directly powering the trains then the RCX 1.0 (with AC jack) isn't manditory. I would love to see the IR train be controled by the RCX. Is reverse engineering the IR codes for the IR train hard to do? Should I try to get the IR control codes spec and post it on ILTCO web site? Who knows how to program the RCX with new IR codes? (Is it that easy???) SteveB The biggest news to me at BrickFest on this was IR control - the RCX can transmit IR, and we've already got it running things like Manas (that may use a very similar protocol). So multiple, RCX-controled (but not powered) trains become a possibility, with the RCX inputs and outputs dedicated to just controling layout features (points, animation, train sensing). And this requires no modification whatsoever, just careful coding of the RCX for IR control. One RCX, controling multiple trains, switching tracks, and loading & unloading stations. If the train folks don't enjoy this, I assure you there's some mindstorms types that are chomping at the bit.

(...) The problem you're gonna find is that the RCX can only point in 1 direction at once. Unless you have many spaced around your layout, you're not gonna be able to control the trains at every point on the layout. That may not be a problem - if (...)

(...) I cracked the Manas codes in ten minutes with a photodiode and an oscilloscope. Turned out they were very easy to transmit from the RCX. I suppose TLG could go to the trouble of inventing an entirely new scheme, but why? The only scary thing (...) (18 years ago, 13-Jan-06, to lugnet.trains, lugnet.dear-lego)

(...) Note that for the strong of heart, this might still allow smaller trolleys... with some ABS shavings. But hacking the motor to allow RP and IR controlability seems a likely direction in any event. (...) Or even when you aren't. The biggest (...)
