A resourceful YouTuber shows he could turn said player into a cheap, laser-based microscope, for instance. <\/p>\n<p>Designed by German YouTuber Doctor Volt, a recent DIY project uses parts of a defective Samsung BD-J5900 Blu-ray player to put a laser-scanning microscope together. Compared to optical microscopes, laser-based microscopes can capture <a href=\"https:\/\/www.hackster.io\/news\/diy-laser-scanning-microscope-built-using-an-old-blu-ray-laser-fdb54bcf3384\">much more details<\/a> \u2013 and with a higher magnification level \u2013 by focusing on a single point at a time to remove interference.<\/p>\n<p>Blu-ray players work in a similar way: the &#8220;blue&#8221; diode beams a 405 nm laser onto a Blu-ray disc surface, and then an optical sensor converts the reflected light into a binary digit (&#8220;1&#8221; or &#8220;0&#8221;) depending on the intensity of the reflection. &#8220;By running that same process and recording each intensity measurement,&#8221; the hacker explains, it is possible to &#8220;create an image of the surface of whatever the laser scans. The resolution is a function of the physical movement of the laser as it scans.&#8221;<\/p>\n<p><picture style=\"padding-bottom: calc(100% * 1125 \/ 2000)\"><source type=\"image\/webp\" data-srcset=\"https:\/\/static.techspot.com\/images2\/news\/bigimage\/2022\/12\/2022-12-23-image-10-j_500.webp 500w, https:\/\/static.techspot.com\/images2\/news\/bigimage\/2022\/12\/2022-12-23-image-10-j_1100.webp 1100w, https:\/\/static.techspot.com\/images2\/news\/bigimage\/2022\/12\/2022-12-23-image-10-j.webp 2000w\" data-sizes=\"(max-width: 960px) 100vw, 680px\"\/><img loading=\"lazy\" decoding=\"async\" height=\"1125\" width=\"2000\" alt=\"\" class=\"b-lazy\" src=\"https:\/\/static.techspot.com\/images2\/news\/bigimage\/2022\/12\/2022-12-23-image-10.jpg\" srcset=\"https:\/\/static.techspot.com\/images2\/news\/bigimage\/2022\/12\/2022-12-23-image-10-j_500.webp 500w, https:\/\/static.techspot.com\/images2\/news\/bigimage\/2022\/12\/2022-12-23-image-10-j_1100.webp 1100w, https:\/\/static.techspot.com\/images2\/news\/bigimage\/2022\/12\/2022-12-23-image-10-j.webp 2000w\" sizes=\"auto, (max-width: 960px) 100vw, 680px\"\/><\/picture><\/p>\n<p>As explained on his YouTube channel, Doctor Volt used several components of his Blu-ray player together with additional plastic parts to create a proper scanning device. The final design can produce images using 16,129 measurements, one 127\u00d7127-pixel image at a time \u2013 which the hacker scaled to 512\u00d7512 pixels for easier reading.<\/p>\n<p><iframe loading=\"lazy\" title=\"DIY Blu-Ray Laser Scanning Microscope Part 2: Shooting Images\" width=\"720\" height=\"405\" src=\"https:\/\/www.youtube.com\/embed\/Hkialty_8K4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p class=\"tsadinc\">Doctor Volt tried to scan different kind of surfaces with his DIY scanner, including a piece of fabric, a sheet of millimeter paper, tiny grooves of a vinyl record. Rendering the final image through a Java-based browser interface takes time and patience, but the alternative is much more expensive than the few tens of dollars spent to create the DIY scanner.<\/p>\n<p class=\"tsadinc\">Doctor Volt estimates his laser scanner can resolve &#8220;structures of roundabout 5 micrometers,&#8221; an incomparably better result than the maximum magnification power of optical microscopes which is typically limited to around 1000x. A DIY solution may be slow and cumbersome, but a commercial laser scanner used in a lab environment can cost tens of thousands of dollars so there&#8217;s nothing to complain about here.<\/p>\n<p class=\"tsadinc\">Besides recording the entire building process and posting it on YouTube, Doctor Volt put together everything that&#8217;s needed to <a href=\"https:\/\/www.hackster.io\/michalin70\/laser-scanning-microscope-from-blu-ray-player-856f06\">replicate his project<\/a> on the Hackster online community. He describes the parts and the story behind the DIY laser scanner, sharing the schematics, and the software source code as well.<\/p>\n<\/p><\/div>\n<iframe src=\"https:\/\/www.fiverr.com\/gig_widgets?id=U2FsdGVkX18x7XQvttUTrv1oEqmGNGTgvvCUiUoJ\/AP4z\/UyMz8lXGOLpu15jIMxBbTR0gmD5uBoFvhC4KWeALQRp3h\/X\/AwcVD0K8Wj9H\/ZzYKzcCNHosB9oS4SCJJFWiN85P9ICAc4OgCoE\/wHKIY7CDkf2\/DQ1vqGvk4smVe5cRDEmrLPCWi4FC8p40VUhSmWQ5udCm0zoJtorgWv3vbDQw0kKYkwn39ozAnQXDe+YvWMxkLFWA+O3TFwkJvdkIK+\/AUSnRssPKt5WHY0FhNOxnSPcLslEL4G4\/RfP95ve99U+kRnDy3X+KtzdQLY+u935ghON\/o3UE4IMv9oN6JX9RnxzL\/LRcOgnHigxStSGPKsZYtnz8RWNVT\/rOLAibqiWJadC5MYHRbekF3eg6FOGrQGkXYbsn0+a5aovnlLCbLwIqY9fcS17UX8J235iQ6cdmHNbrPeS84CMm34RA==&affiliate_id=1052423&strip_google_tagmanager=true\" loading=\"lazy\" data-with-title=\"true\" class=\"fiverr_nga_frame\" frameborder=\"0\" height=\"350\" width=\"100%\" referrerpolicy=\"no-referrer-when-downgrade\" data-mode=\"random_gigs\" onload=\" var frame = this; var script = document.createElement('script'); script.addEventListener('load', function() { window.FW_SDK.register(frame); }); script.setAttribute('src', 'https:\/\/www.fiverr.com\/gig_widgets\/sdk'); document.body.appendChild(script); \" ><\/iframe>\n<br \/><a href=\"https:\/\/www.techspot.com\/news\/97066-turning-blu-ray-player-parts-cheap-laser-scanning.html\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In brief: Even though Blu-ray players have been mostly replaced by streaming and video-on-demand services, they can still serve a purpose.
