Hi,
How does the RCX handle things when there are batteries installed
and it is also plugged in via the power jack? Does it use the external
power first? I was curious if it would be possible to make a solar
panel to power the RCX when there is enough light, but then rely on the
batteries kicking in when the amount of light was not sufficient.
Is there any easy way to tell when the RCX is uing the enternal power
supply? I tried using an external power adapter for testing, but
couldn't see and visual display on the LCD to show it was using external
power.
Any ideas?

| (...) No, there is no way to tell as far as I know. I believe the choice of power source is done by circuitry, not logic. I do believe that the external power supply is used in preference to the batteries, but this might not really be the case - you (...) (26 years ago, 9-Nov-98, to lugnet.robotics)

| Along the same line, does anyone have the specs on the co-ax power plug itself? diameter (outside & inside) and the polarity? I dont want to fry my brick through experimentation... Thanks, Tom (determining if there is circuitry involved should have (...) (26 years ago, 10-Nov-98, to lugnet.robotics)
