  Re: GP2D12 IR sensor RCX active sensor interface?
 
FYI - I just noticed in the component specs from Sharp that the GP2D12 (and GP2D15 for that matter) have a built-in voltage regulator. See (URL) is an external regulator a necessary precaution? Just curious... - Gareth (24 years ago, 9-Oct-01, to lugnet.robotics.rcx)

  Re: GP2D12 IR sensor RCX active sensor interface?
 
(...) Hi Gareth, I guess the three wire solution won't work. (Not tested it myself) The Sharp GP2D12 have a current consumption of about 35mA-50 mA (at 5V) !!!! Michael Gasperi mentioned that an input of the RCX only give about 15mA. ((URL) techno (...) (24 years ago, 8-Oct-01, to lugnet.robotics.rcx)
