In this video, Tech Tangents reviews the Andonstar AD246S-P digital microscope and uses it to achieve a "world's first" by capturing clear images of video data and text directly from the surface of LaserDiscs and CEDs (Capacitance Electronic Discs).
Microscope Overview and Setup Purpose: The creator purchased the microscope specifically to document the microscopic structures of obsolete media like CEDs for the public domain [00:14].
Features: It features a 1080p sensor, HDMI output, and a flip-down display [02:41]. He notes the importance of the included remote control to prevent camera shake at high magnification [04:10].
Build Quality: He highlights thoughtful design choices, such as captive plastic inserts in the screws to prevent them from biting directly into the metal support tubes [05:51].
Initial Testing and Performance Coins and Wafers: The microscope provides impressive clarity when viewing historical coins and silicon wafers, where individual dies and traces are easily visible [11:30].
Magnification Concerns: He expresses skepticism regarding the "ridiculous magnification claims" often found on these products, finding that the high-magnification lens can sometimes be hazy [13:07].
Visualizing Video Data on Physical Media The core of the video focuses on using light refraction (diffraction grading) to see the physical encoding of video signals.
LaserDisc (CAV): Using a "The Mind's Eye" LaserDisc, he successfully identifies horizontal blanking pulses and color bursts in the disc's pits and lands [16:27].
Reading Text on a LaserDisc: In a major breakthrough, he discovers that by positioning a flashlight at a specific angle, he can actually read the end-credit text (e.g., the word "Keyboard") directly off the disc surface [22:54].
CED (Capacitance Electronic Disc): He examines a damaged CED of the movie True Grit. He manages to capture a remarkably clear image of the film's credits etched into the disc's microscopic grooves [25:57].
Additional Observations Optical Media Tracks: The microscope is used to visualize the distinct data sessions and track separators on a CD and a CDRW [27:00].
Smartphone Sub-pixels: A close-up of a Samsung S24 Ultra display reveals the sub-pixel arrangement of its OLED screen [28:37].
Conclusion: The creator concludes that the Andonstar AD246S-P is highly effective for technical documentation and hobbyist use, especially given its ability to resolve the fine details of analog video media [28:57].
some religious lunatics would deem that worthy
Economically, allying with Russia is stupid, they're poor. The only way they are making it through this war economy is the fact that Russian people are patient and are used to bad economy. The average anual salary in Russia is below $10K.
They are not going to risk their security for Ukraine. They wouldn't risk starting a nuclear war over Ukraine, it's stupid, even for their standards
But we should have the option to choose. Apple is very anti-consumer, making all the choices (often bad ones) for us, giving us none. The court should rule to open Apple more. Android is open enough that you can do whatever you want, yet not complicated enough so people get confused with all the options you have.
