Lo-Fi reloaded.. Experimenting on cutting / engraving / embossing audio tracks into obsolete CDs. The cutting lathe was built around cigar boxes.
The previous cutter heads were crap - this time i kept it as simple as possible: A Visaton "EX 45 S Exciter" with a sharpend drill glued on it. That loudspeaker doesn't have membrane but a plastic mounting plate which vibrates.
The soundfile was equalized with the Audacity program; high frequencies above 6kHz were cut off, the rest was equalized with an inverted RIAA filter. The feed screw for the cutter head traction is now installed, which brings a better linear motion and more recording time (in the video it was only moved by hand).
The track I used for experimenting is "Try Me", taken from Meena Cryle. Check them out, they're great! www.meenacryle.com
