This video demonstrates building a "faux infinity mirror" effect around a TV screen using recycled materials. The creator utilizes a broken LCD monitor, extracting its backlight and diffuser panel. These are then combined with a one-way mirror film applied to a picture frame and strategically placed LED strips to create the illusion of depth and infinite reflections behind the TV. The project highlights a resourceful way to enhance a standard television's aesthetic using readily available, discarded electronics.
The post details an exploit targeting the Xbox 360's hypervisor, specifically through a vulnerability in the console's update process. By manipulating the order of CB/CD images on a specially crafted USB drive during a system update, the exploit triggers a buffer overflow in the hypervisor's handling of image metadata. This overflow overwrites critical data, allowing the attacker to gain code execution within the hypervisor itself, effectively bypassing the console's security mechanisms and gaining full control of the system. The post specifically focuses on the practical implementation of the exploit, describing the meticulous process of crafting the malicious update package and the challenges encountered in triggering the vulnerability reliably.

HN commenters largely praised the ingenuity and DIY spirit of the project, with several expressing admiration for the creator's resourcefulness in using recycled materials. Some discussed the technical aspects, questioning the actual contrast ratio achieved and pointing out that "infinity contrast" is a misnomer as true black is impossible without individually controllable pixels like OLED. Others debated the practicality and image quality compared to commercially available projectors, noting potential issues with brightness and resolution. A few users shared similar DIY projection projects they had undertaken or considered. Overall, the sentiment was positive, viewing the project as a fun experiment even if not a practical replacement for a standard TV.
The Hacker News post linking to the YouTube video about a DIY "infinity contrast" TV built with recycled parts generated a moderate number of comments, mostly focusing on the technical aspects and feasibility of the project.
Several commenters questioned the use of the term "infinity contrast," pointing out that while the approach improves black levels, it doesn't achieve true infinite contrast. They argued that some light still leaks through, and the contrast ratio, while improved, is finite. This sparked a discussion about the definition and practical limitations of contrast ratios in display technology.
One commenter discussed the challenges of achieving perfect black levels and how even high-end OLED displays struggle with near-black gray uniformity, where different areas of the screen might display slightly different shades of near-black. This ties into the broader conversation about the limitations of display technology and the trade-offs involved in different approaches.
Another line of discussion revolved around the practicality of the project. Commenters debated the cost-effectiveness of building such a display versus buying a commercially available one, especially considering the time and effort involved in sourcing and assembling the components. Some also questioned the longevity and reliability of a DIY solution compared to manufactured displays.
There were also comments appreciating the ingenuity and resourcefulness of the project, highlighting the value of repurposing old technology. Some users expressed interest in trying similar projects or suggested alternative approaches to achieving similar results. A few commenters shared their own experiences with similar projects involving projection systems and ambient light rejection techniques.
Finally, a few commenters provided additional technical insights into the workings of projection systems and the specific components used in the video, offering further context for those interested in understanding the technical details of the project.
