Reading the patent document of Thomas Edison’s tin foil phonograph of 1878, we were fascinated to see that it encompassed electrical recording, via an electromagnet (solenoid).
Also, magnetic recording on a strip of ferrous metal!
We had no choice but to attempt a working model of Edison’s electric cylinder phonograph. 😀
We tinkered with it for 2 or 3 months. Some progress was made, but it was very much an uphill task.
So eventually we gave up, simply turning it into a youtube video, so that other people doing this sort of thing would know that they were not alone. 😊
Hope you like it!
Cheers
