Glad I read the article, this is fascinating:
> In 2012, a LightScribe optical drive was successfully used by Maher El-Kady, a graduate of UCLA, to turn a specially prepared graphite oxide layer coated onto a DVD into graphene.[10] El-Kady and Richard Kaner, his lab professor, used an unmodified LightScribe drive. The disc was prepared by coating the disc with an aqueous solution of graphite oxide and allowing it to dry. Areas of the coating illuminated by the LightScribe laser were turned into graphene. Various shapes can be drawn, which allowed the scientist duo essentially to laser-print an ultracapacitor on graphene using consumer-grade technology.
Sun used to say “the network is the computer”.
Now you are telling me we could potentially have “the DVD is the computer”. Imagine printing not just a capacitor but a whole PCB and soldered components, putting the innards of like a Raspberry Pi on top of a specially crafted DVD that has said single-board on one side and a readable DVD surface on the opposite side! :D
