I am really intrigued at the application of pneumatics, especially for small-scale automated processes. Realistically, how small are the components of such a system? -- Ioneill 08:45, 27 November 2007 (UTC)

There is no limit in size, neither in small nor in big scales. It depends on the use case. The resistors I have worked with are about 2 cm long, which is a good size for easy handling. The capacitors were about 4 cm high with a 3 cm diameter. I have built for example a pneumatic astable multivibrator with optical signal output. I will add a pneumatic optical signal output element to the pneumatics page, soon. For sure, it is even possible to make integrated circuits. I have seen a high sophisticated PID controller the size of a foot, made of pure pneumatics.
Yes, it is an amazing technology. Do you remember the flux capacitor in "Back to the future"? Doc Brown announced, the principle is universal, and it works with steam as well. In the year 1885 he had no electronics, but he managed to do it with steam. Okay, this is science fiction. But the functioning of pneumatics is true. It has been widely used in automation in the 1980, especially in factories with dangerous explosive gases. -- Rfc 10:14, 27 November 2007 (UTC)
Wow. That is very cool. I took electronics in college and I am really interested in how circuit function can be replicated by pneumatics, it's a big conceptual step to make! I'll look forward to hearing about more applications :) -- Ioneill 19:24, 27 November 2007 (UTC)
