(...) Billy, I'm pretty sure you could, but I doubt you'd want to use a piston per bit of memory. (...) Instead you might want to use a 1x10 technic brick, with long pins with friction in them. The idea being that you can slide the pins in the (...) (19 years ago, 19-Nov-05, to lugnet.technic)

Hi Like Tommy Eriksson I have also decided to post a reply to this old thread. I am in the process of trying to make LEGO fly but unlike Tommy, I am going for a small light powered glider that is catapulted from a Technic "ballista-like" affair that (...)

You guys are smart. I get lost reading your posts but can appreciate the genius displayed in them. Could pneumatics be used to pump a liquid? I mean, you know how air pressure is used in spray bottles/soap dispensors? The moving air goes over a gap (...) (19 years ago, 19-Nov-05, to lugnet.technic)

Hi all. I'm sorta new here so, I'm not real familiar with way the forums work. Anyhow, having seen the three position piston control by Kevin L. Clague, and other various pneumatic logic devices using Boolean logic and Boolean gates, I was (...) (19 years ago, 19-Nov-05, to lugnet.technic)

(...) Just so. (...) No, it wouldn't walk backwards. To make it work, you'd only have to interchange the hoses at the switches. That's because a suction force acts in the opposite direction to the traditional compressed air. Your walker will then (...) (19 years ago, 19-Nov-05, to lugnet.technic, FTX)

(...) Thanks, Kevin. Had to break-in as matters seem to be getting outta hand. It appears we're getting a new generation of pneumatic fans. Great! (...) No, you use them the same way. The pneumatic switch is basically a directional control valve. It (...) (19 years ago, 19-Nov-05, to lugnet.technic)

(...) It is possible to combine multiple switches into a release-free switch, but they would probably be more load than a single switch used on dual ported piston. Kevin (...) (19 years ago, 19-Nov-05, to lugnet.technic, FTX)

(...) I'm glad if I saved you some bucks. The fourth exhaust port is a necessity (for the cylinders to work) and a nuisance (being inaccessible). I first learned about it from Erik Brok's site. In real-life pneumatics, this port would be brought out (...) (19 years ago, 19-Nov-05, to lugnet.technic)

(...) Hi Dr. Soh, Nice to hear from you. I've never actually built with the original pneumatics, but my understanding is that the way to use switches in the old pneumatics is different than the way you use them with dual ported pistons. Don't you (...) (19 years ago, 18-Nov-05, to lugnet.technic)
