I didn't know they existed. 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 itself the mux is not that interesting, so I needed an example to show it off. I'm working on LEGO pneumatic computing mechanisms for projects beyond PneumAddic and PneumAddic II. http://www.users.qwest.net/~kclague/pneumaddic/index.htm http://www.users.qwest.net/~kclague/pneumaddicII/index.htm > > ROSCO Kevin

(...) Very cool Kevin! Have you thought of using a sliding linkage like steam train valves? It would make it less than 100% pneumatic, but might make it somewhat less complex. ROSCO (21 years ago, 1-Jun-03, to lugnet.technic)
