Clocks Made From Vinyl Records

In 1877, Thomas Edison developed the phonautograph into a machine, the phonograph, that was capable of replaying the recordings made. The recordings were made on tinfoil, and were initially intended to be used as a voice recording medium, typically for office dictation.
In the early days of compact discs, vinyl records were still prized by audiophiles because of better reproduction of analog recordings; however, the drawback was greater sensitivity to scratches and dust. Early compact discs were perceived by many as thin and sharp—distorting sounds on the high end. In some cases, this was the result of record companies issuing CDs produced from master recordings that were compressed and equalized for cutting. Early consumer compact disc players sometimes contained 14-bit digital-to-analog converters, instead of the correct 16-bit type, as a cost-cutting measure. Some players were only linear to 10 or 12 bits.
