The Secret Society of Lathe Trolls

You are overthinking the audio works, you don't need magic just trim the frequencies you want and have the arduino sample multiple input pins to "hear" the various frequencies. You could have it read a summed voltage to detect the places you need to worry about. I don't understand it, the proof of c...

I too am about to build my own. Everything you basically need outside of amazon https://www.automationtechnologiesinc.com You need a WAY bigger motor, over 1000oz torque to get what you want at full speed. https://www.automationtechnologiesinc.com/products-page/nema-34/nema-34-12-dual-shaft-with-fla...

First thank you for saving me a bunch of time. I was in the process of copying Neumanns old mic designs updated for modern voltages (45B+ on tube and 250vdc in, post war Germany, it was what they had) and more easily available tubes, 6AS6 subbing in for a vf14, when I found his lathe designs and eve...
