If you’d like to bulk copy CDs/DVDs without the sticker shock of a $500+ commercial duplicator, this DIY LEGO duplicator is a homebrew solution.

Paul Rea wanted to rip and copy CDs and DVDs without shelling out for a commercial duplicator and without the hassle of being bound to that commercial duplicator’s propriety software. His homebrew solution–a combination of LEGO, a rotating base, an Arduino controller, and little ingenuity–handles his ripping and copying needs with ease. Watch the video above to see it in action then hit up the link below for the build log and Arduino code.
