Only recently, just 2-3 years ago, I discovered Mechanical TV, Mechanical amplifier. I was pleasantly surprised. Mechanical TV was invented by Beard. Mechanical amplifier uses air pump to amplify the sound, completely avoiding any electronics. Also, it seems there exists mechanical frequency filters such as low-pass filters or band pass filters. Edison's phonograph was a mechanical equivalent of today's audio-recording and player machine. Music box that employs camshaft also may be thought of as a mechanical equivalent of an music producing machine from ROM.
I was wondering are there any other such Mechanical equivalents of electronic devices ?
