| | | | | Hi People, I really appretiate the circuits Mark has put up, they are very instructive, and between you you guys are taking Lego pneumatics before I have seen it go before. But - in your diagrams, you do not label the components - which make them (...) (19 years ago, 9-Aug-05, to lugnet.technic)

This reduces the balloon effect in the model, so its use is desirable (...) (19 years ago, 9-Aug-05, to lugnet.technic)

With pistons, I consider them XOR gates. They work very well. Thanks (...) (19 years ago, 3-Oct-05, to lugnet.technic)
