I have built another pneumatic compressor and pressure switch; I believe both are improvements on the previous designs. The compressor is full-stroke, double-pump, uses the new 9v motor and is rather small; the pressure switch is similar to Ralph Hempel's one but is more compact. Both compressor and switch designs adhere to exact LEGO geometry, so I expect them to perform well in real models. http://www.malgil.com/esl/lego/pneumatics.html Any comments/suggestions/test results are appreciated...

		Re: Another pneumatic compressor and pressure switch designs
I've seen lots of designs but none have enough power, air-wise. I need pressure and volume! I made a good one once using two of the large spring loaded pumps. But that was using really old technic motors.... the mindstorms motors are much to weak to (...) (24 years ago, 22-Jun-00, to lugnet.build, lugnet.robotics, lugnet.technic)

		USB IR tower?
Does anybody know if a USB version of the Mindstorms' IR tower has been seriously considered, and/or if one would happen to be in the works? One would normally use a USB-serial converter if stuck using only USB, but I'm also stuck in an environment (...) (24 years ago, 3-Jul-00, to lugnet.robotics)

(...) I'm almost certain that the upcoming RCX 2.0 's IR-Tower is USB. (...) A RF comms would be even nicer, like my Cybermaster :) The only advantage of a USB-PBrick instead of a RF-PBrick(+IR to inter-PBrick comms) would be that the PBrick could (...) (24 years ago, 4-Jul-00, to lugnet.robotics)
