| | | (...) 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 (...) (23 years ago, 8-Oct-01, to lugnet.robotics.rcx)

| | | | 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 (23 years ago, 9-Oct-01, to lugnet.robotics.rcx)

| | | | (...) Hi Gareth, maybe you don't need an external regulator ?!?! But, the specs also say that rating of supply voltage is "-0.3 to +7V". Do you know what happens to the sharp if supply voltage rises above +7V ??? (the mux has a supply voltage of +9V (...) (23 years ago, 9-Oct-01, to lugnet.robotics.rcx)

| | | | Hi all, It seems I missed this thread... (...) As suggested by Rainer, if you use an external battery everything is much simpler, you could even use a 4.5V battery to avoid regulator. (...) I don't think you can improve this circuit with a simple (...) (23 years ago, 10-Oct-01, to lugnet.robotics.rcx)
