| | | Can I put an electric 2x4 plate across output port A and B to increase the current I can draw from the brick? Chris 1. when I ran a few tests with a 1x2 lamp, I would get interesting results. A and B forward - ON A and B Reverse - ON A Forward B (...) (18 years ago, 21-Jul-06, to lugnet.robotics.rcx)

| | | | Hi Chris, (...) I think so (warning, this is based only on theoretical knowledge). (...) That should be ok. Setting the power level might not work correctly, from looking at the ROM code it seems the PWM waveforms are not synchronized. Now comes the (...) (18 years ago, 22-Jul-06, to lugnet.robotics.rcx)

| | | | | (...) If all motor ports are started and stopped together, does that synchronise the PWM waveforms? If not, then I don't recommend paralleling up. If so, then I recommend paralleling up only when motors are started and stopped together and are run (...) (18 years ago, 23-Jul-06, to lugnet.robotics.rcx)

| | | | | | Hi Mark, (...) probably, I guess they would be started within the same millisecond, which would result in synchronized wafeforms. (...) It's not that bad, when the waveform is off the motor is floating. So the power control will be ineffective at (...) (18 years ago, 23-Jul-06, to lugnet.robotics.rcx)

| | | | (...) The flashing is a feature of the 1x2 and 1x4 lamps... if run in one direction, it's solid, but in the other it flashes. This comes from the old light and sound sets, where you might well want a flashing light. You're right that the two outputs (...) (18 years ago, 23-Jul-06, to lugnet.robotics.rcx)
