Hi, Here is a link on how to hook up the GP2D02 to the RCX (URL) It seems to be overly complicated. Not to put down on Peter's creation as I think it was ingenious, but there must be a easier way to do this instead of compromising an input & an (...) (23 years ago, 11-Jan-01, to lugnet.robotics)

(...) Hi Ram, I don't know an easier way of using GP2D02 but why don't you use the GP2D12 instead ? It has an analog output. You don't have to analyze any serial protocol. And as the lego light-sensor has a driven light source, it should be possible (...) (23 years ago, 11-Jan-01, to lugnet.robotics)

(...) somewhere I read that the lego motors have a power consumptions from 100mA normal up to 450mA stalled. Am I wrong with this ? BTW why not use an external power pack if necessary ?

Adding a power pack to the interface isnt really a problem. How would you connect it if we use an external power supply? Can we just use Michael's GPAI at (URL) Sorry about the basic questions, I am a software engineer not an electrical engineer... (...) (23 years ago, 11-Jan-01, to lugnet.robotics)

Unless I am missing something here, the Sharp range of IR distance sensors all have power consumptions in the 35mA range, which prohibits their use with the RCX unless you resort to using external power packs. How do you propose getting around this (...) (23 years ago, 11-Jan-01, to lugnet.robotics)

(...) Makes no sense for use with GP2D02 (uses serial protocol). Using the more general purpose analog interface (the one with the opamp) should work well with GP2D12 I think (I'm also no electrical engineer). You can adjust the output then (Sharp (...) (23 years ago, 12-Jan-01, to lugnet.robotics)

Hi, I asked this problem a few weeks (or months??? ... I don't know a what time ...) but nobody could help. I got the same following answer ".... the sensor takes 35 mA and this is to much for the RCX ..." but I couldn't understand this at this (...)
