Pneumatic pump and switch using a single motor: Do you need pneumatics on your robot? You want to produce the pressure and you want to switch the valve by motors. With my idea you can do both with a single motor. Have a look at: (URL) for my bad (...) (25 years ago, 23-Oct-00, to lugnet.robotics, lugnet.announce)

I am now using MacNQC 2.2a3. It seems it cannot understand some new syntax than can be used in NQC 2.2r2. (Such as EVENT()...) Can anyone teach me what should I do? Camus Lai (25 years ago, 23-Oct-00, to lugnet.robotics)

(...) If your using the Tower a lot of the time, (Polling etc.) I'd suggest getting a power adapter for 9 volts and use that instead. Saves on power greatly. Dean -- Coin-Op's For Sale!: (URL) Lego Workshop: (URL) Lego Club: (URL) (25 years ago, 23-Oct-00, to lugnet.robotics)

I had a similar problem with the RCX. I use the RCX and it works well with 1,2V NiCd batteries as soon as the tower uses a regular 9V battery. If I use a rechargable 9V battery I have a problem similar to yours. Try using a regular 9V battery and (...) (25 years ago, 23-Oct-00, to lugnet.robotics)
