(...) What can I say? Yet another amazing creation. You have a pneumatic control circuit in there somewhere, I think. I know what you mean about the small pneumatic cylinders needing such high pressure to move a switch. The engine I built following (...) (21 years ago, 16-Jun-03, to lugnet.technic, lugnet.robotics)

The other day I was given a challenge to make a small biped using small pneumatic pistons. Normally I don't use small pistons in combinations with switches, because the pressure must be increadibly high for a small piston to flip a pneumatic switch (...)

I just went to the Lego S@H website and there are a number of new Technic sets there. In particular, the ten-piston 8455 Backhoe set is finally out and at $100 for all those pneumatics it is quite a deal too. I'm going to order some of this stuff (...) (21 years ago, 15-Jun-03, to lugnet.technic)

(...) You are doing well Mark. You can use three voltage comparators to detect which voltage level is being output. What you need is three comparators. One for 25%, then 50%, and 75%. If 75% is on, then you'll need to gate off the 25% and 50% (...) (21 years ago, 15-Jun-03, to lugnet.technic, lugnet.robotics)

So for controlling up to four devices from one port, for example, would require that 25% power to (...) (21 years ago, 15-Jun-03, to lugnet.technic, lugnet.robotics)
