| | | Besides bipeds, I also love LEGO pneumatics. Doug Carlson and I have been trying to work on techniques for making single piston pneumatic engine with little or no flywheel. Doug has been having better luck than I but neither of us have acheived the (...) (21 years ago, 1-Jun-03, to lugnet.technic) !

That is the problem with a computer engineer designing a reversible pneumatic engine ;^) To be honest, the reversible engine was used as an example to show off the multiplexer. By (...)

This is not the first reversible engine. I will soon upload photos to Brickshelf. My version is (...) (21 years ago, 1-Jun-03, to lugnet.technic)

With longer tubes, I could have easily hooked the two multiplexers to the same (...) (21 years ago, 1-Jun-03, to lugnet.technic)

That is why it looks so different than yours. I'm sure that if you build one of the (...) (21 years ago, 2-Jun-03, to lugnet.technic)
