One other interesting thing about this idea-- If it works, not only will you get the optical sensor, but you can probably get up to 5 touch sensors and a rotation sensor at the same time. I'm not sure how the signal is sent, but will the RCX be able (...) (22 years ago, 1-Jul-02, to lugnet.robotics)

This whole thread just caused an interesting thought to pop into my head, although I suspect it would only apply to cases where LegOS were being used. If the mouse serial port output (transmit line) were to be connected to a LMC555 (running at (...) (22 years ago, 1-Jul-02, to lugnet.robotics)

Hi - I posted a letter just before and I don't know If it went thru. I take it again there - Is there some hardware modifications to Mindstorm so it can have more IO ports - like more Motor control ports and more sensor ports? - And a second thougt (...) (22 years ago, 1-Jul-02, to lugnet.robotics)

(...) What about using a cordless mouse? One could fiddle withthe optical problems first and could use the normal IR tower to send position information to the RCX. Michael (22 years ago, 1-Jul-02, to lugnet.robotics)

(...) No, pbForth can easily read arbitrary chars coming in on the IR prot, we'd just need to switch the RCX to 1200 baud... (...) John, If you send me a modified mouse, I'll do the other Forth stuff needed to get this working in a weekend. Cheers, (...) (22 years ago, 1-Jul-02, to lugnet.robotics)

The Ferarri book yalks about some ways to add input or output ports. The option that looks most promising to me is detailed at (URL) that site: "I'm very Pleased to announce that my latest project the '(MS)2 Expander' will expand your RCX's ports (...) (22 years ago, 3-Jul-02, to lugnet.robotics)

I have chased this topic around quite a bit in the last couple of years and built a few prototype devices to perform "I/O expansion". My final conclusion, having gone to the trouble of building a device which permits two of the RCX motor ports and (...) (22 years ago, 5-Jul-02, to lugnet.robotics)
