Great timing. I just bought a PICkit2 to play with the other day. Any chance you already have the I2C slave interface for the NXT for the PIC? That way I can only concentrate on the specific code for a custom input/output device. (18 years ago, 30-May-07, to lugnet.robotics)

We added a special programming environment for a series of PICs to the Ultimate ROBOLAB site www.ultimaterobolab.com. To distinguish it from RCX-Ultimate Robolab, we called it PICLab. This is a powerful tool for PIC programming. The result is .asm (...) (18 years ago, 30-May-07, to lugnet.robotics)

(...) It's not ideal for stock LEGO sensors I think, but it might be good to point out to them that the reason it blinks is to make things *easier*. With a source pulsing near a known frequency, ambient conditions are much easier to cancel out. (...) (18 years ago, 29-May-07, to lugnet.robotics.edu)

(...) Well, if by "more qualified" you mean "have abused their hardware harder than average, yes :-). Since day 1 I've back-driven the NXT motors by hand, including the magic motor demo (not as efficient with the NXT motors, but it does work), using (...)

(...) Well, I don't want to claim to be an expert, but I'll tell you what I've done. I have a couple remotes that I've been using for over a year, and I haven't had problems with them. One not only uses the rotation sensors, but also uses the motors (...) (18 years ago, 29-May-07, to lugnet.robotics.nxt)

Hand crank it alone should be find. As a matter of fact, that's how we demonstrate to kids a generator. However, just to be on the safe side, I would recommend you not to hand crank it when it is hooked onto to the power source, especially when it (...) (18 years ago, 28-May-07, to lugnet.robotics.nxt)

(...) John, there are a lot of people using the NXT motors this way, just to get the feedback from the built-in rotation sensors. The best example would be the MDPers who built one joystick with a NXT kit to control a moving vehicle made with (...) (18 years ago, 28-May-07, to lugnet.robotics.nxt)

Hi John, I would not think so, as the NXT's own construction guide has a pick and place (blue ball, red ball) robot, that has hand cranks to move it into position. Danny (...) (18 years ago, 28-May-07, to lugnet.robotics.nxt)

Hi: Sometimes my son and I move the NXT motors by hand, for instance, by attaching something to the holes in the orange hubs to act as a crank. We wonder if that's bad for the motors. Does anyone have an opinion? Regards, John and Will (18 years ago, 28-May-07, to lugnet.robotics.nxt)
