A solution for a large part of e-waste?
This Youtuber presented a very clever hack in which any old Blu-Ray player can be turned into a digital microscope.
Since Blu-Ray drives use lasers to read tiny dots on the surface of a disk, they work similarly to a microscope, so they can be turned into one. The hack doesn’t present a device that can compete with professional microscopes, which retail for thousands, but it’s certainly a good way to repurpose the now-obsolete Blu-Ray drives.
The hacker, the YouTuber Doctor Volt, used a few custom parts as well, but all of them can be had on the cheap.
After watching the video above, which is a fascinating engineering tour, you can also get started on your own project.
Doctor Volt uploaded a walkthrough, including schematics and the source code for controlling the microscope – you can find it here.
