Here's my latest pneumatic logic gate with differential inputs and outputs. This one has 4-switch reversers to make it configurable for almost any combination of inputs. Replace the reversers with permanently swapped hoses when you have the function (...) (19 years ago, 6-Sep-05, to lugnet.technic)

(...) Hi Mark, It sounds like the swiss army knives of pneumatic logic gates! Seriously though, it is going to take some serious study on my part to understand what all is going on here. Are you putting polarity reversors on all inputs and outputs? (...) (19 years ago, 6-Sep-05, to lugnet.technic)

(...) Mark, Aren't Reversor R1 and Reversor R4 redundant? R1 can reverse the A input, which drives a piston which controls a switch, who's output is reversed by R4. I see no reason for the piston and switch between R1 and R4, unless you are just (...) (19 years ago, 6-Sep-05, to lugnet.technic)

(...) I am really getting the feeling that between you guys, you are really pushing pneumatic logic generally, not just in terms of Lego. Have you thought of taking some of your Lego logic designs, and miniaturising them into blocks? Even better is (...) (19 years ago, 6-Sep-05, to lugnet.technic)

(...) Yes, R1 and R4 are redundant as shown in the table notes :-) The idea was to start with A, B and C all being either differential inputs or switch positions. The use of a switch for A means that its input is buffered to the gate output, (...) (19 years ago, 6-Sep-05, to lugnet.technic)

(...) Yes, for the moment, as a demo of how versatile the circuit can be. The idea is that you find your chosen function and put permanent hose swaps in the places where you no longer need to change polarity. Then just keep reversers in the places (...) (19 years ago, 6-Sep-05, to lugnet.technic)
