IR Point And Shoot Has A Raspberry Heart In A 35mm Body

Photography is great, but sometimes it can get boring just reusing the same wavelengths over and over again. There are other options, though and when [Malcolm Wilson] decided he wanted to explore them, he decided to build a (near) IR camera. 

The IR images are almost ethereal.

The housing is an old Yashica Electro 35 — apparently this model was prone to electrical issues, and there are a lot of broken camera bodies floating around– which hides a Pi NoIR Camera v3. That camera module, paired with an IR pass filter, makes for infrared photography like the old Yashica used to do with special film. The camera module is plugged into a Pi Zero 2 W, and it’s powered by a PiSugar battery. There’s a tiny (0.91″) OLED display, but it’s only for status messages. The viewfinder is 100% optical, as the designers of this camera intended. Point, shoot, shoot again.

There’s something pure in that experience; we sometimes find stopping to look at previews pulls one out of the creative zone of actually taking pictures. This camera won’t let you do that, though of course you do get to skip on developing photos. [Malcom] has the Pi set up to connect to his Wifi when he gets home, and he grabs the RAW (he is a photographer, after all) image files via SSH.  Follow the link above to [Malcom]’s substack, and you’ll get some design details and his python code.

The Raspberry Pi Foundation’s NoIR camera shows up on these pages from time to time, though rarely so artistically. We’re more likely to see it spying on reptiles, or make magic wands work.  So we are quite grateful to [Malcom] for the tip, via Petapixel. Yes, photographers and artists of all stripes are welcome to use the tips line to tell us about their work.

This Week In Security: Anthropic, Coinbase, And Oops Hunting

Anthropic has had an eventful couple weeks, and we have two separate write-ups to cover. The first is a vulnerability in the Antropic MCP Inspector, CVE-2025-49596. We’ve talked a bit about the Module Context Protocol (MCP), the framework that provides a structure for AI agents to discover and make use of software tools. MCP Inspector is an Open Source tool that proxies MCP connections, and provides debugging information for developers.

MCP Inspector is one of those tools that is intended to be run only on secure networks, and doesn’t implement any security or authentication controls. If you can make a network connection to the tool, you can control it. and MCP Inspector has the /sse endpoint, which allows running shell commands as a feature. This would all be fine, so long as everyone using the tool understands that it is not to be exposed to the open Internet. Except there’s another security quirk that intersects with this one. The 0.0.0.0 localhost bypass.

The “0.0.0.0 day exploit” is a bypass in essentially all the modern browsers, where localhost can be accessed on MacOS and Linux machines by making requests to 0.0.0.0. Browsers and security programs already block access to localhost itself, and 127.0.0.1, but this bypass means that websites can either request 0.0.0.0 directly, or rebind a domain name to 0.0.0.0, and then make requests.

Running An Entire PS1 Emulator In A DS Cartridge

Gaming on a Nintendo DS can bring back great memories of long car trips from the past. But looking back, we remember wishing to play more than the DS could ever hope to handle. [fami] looks into the SuperCard DSTWO in her recent video, a solution to our past sorrows.

Able to play anything from the very games designed for the DS to emulated PS1 games, the DSTWO is more than capable of surpassing the abilities of the DS itself. More impressively, all games are run directly from the cartridge itself rather than on the DS’s hardware. While this emulated console within a handheld is impressive, it is far from simple to get running.

The DSTWO runs with an Ingenic JZ4732 as the CPU, completely different from any native architecture of the DS. Pair this with the unhelpful SDK made for the cartridge, and the aging hardware is held together by the community development behind any improvements. This is aided by the CPU similarities of another widely modded game console, the Dingoo A320.

When not having a fit, and after going through hours of troubleshooting, you might find the DSTWO running a game of SimCity 2000 or even Spyro the Dragon inside a DS. Even with the difficulties of use, the fact that these games run at all is impressive. If you want to try the DSTWO emulation yourself, check out the forums.

This is far from the only example of extreme care going into emulation. Here at Hackaday, we have covered similarly impressive projects such as this completely DIY handheld made for any retro game emulation you throw at it.

Last Chance: 2025 Hackaday Supercon Still Wants You!

Good news, procrastinators! Today was going to be the last day to throw your hat in the ring for a slot to talk at Supercon in November, but we’re extending the deadline one more week, until July 10th. We have an almost full schedule, but we’re still missing your talk.

So if the thought of having missed the deadline fills you with regret, here’s your second chance. We have spots for both 40-minute and 20-minute talks still open. We love to have a mix of newcomers as well as longtime Hackaday friends, so don’t be shy.

Supercon is a super fun time, and the crowd is full of energy and excitement for projects of all kinds. There is no better audience to present your feats of hardware derring-do, stories of reverse engineering, or other plans for world domination. Where else will you find such a density of like-minded hackers?

Don’t delay, get your talk proposal in today.

Finally, An Extension To Copyright Law We Can Get Behind

Normally when a government extends a piece of copyright law we expect it to be in the favour of commercial interests with deep pockets and little care for their consumers. But in Denmark they do things differently it seems, which is why they are giving Danes the copyright over their own features such as their faces or voices. Why? To combat deepfakes, meaning that if you deepfake a Dane, they can come after you for big bucks, or indeed kronor. It’s a major win, in privacy terms.

You might of course ask, whether it’s now risky to photograph a Dane. We are not of course lawyers here but like any journalists we have to possess a knowledge of how copyright works, and we are guessing that the idea in play here is that of passing off. If you take a photograph of a Volkswagen you will have captured the VW logo on its front, but the car company will not sue you because you are not passing off something that’s not a Volkswagen as the real thing. So it will be with Danes; if you take a picture of their now-copyrighted face in a crowd you are not passing it off as anything but a real picture of them, so we think you should be safe.

We welcome this move, and wish other countries would follow suit.

This Week In Security: MegaOWNed, Store Danger, And FileFix

Earlier this year, I was required to move my server to a different datacenter. The tech that helped handle the logistics suggested I assign one of my public IPs to the server’s Baseboard Management Controller (BMC) port, so I could access the controls there if something went sideways. I passed on the offer, and not only because IPv4 addresses are a scarce commodity these days. No, I’ve never trusted a server’s built-in BMC. For reasons like this MegaOWN of MegaRAC, courtesy of a CVSS 10.0 CVE, under active exploitation in the wild.

This vulnerability was discovered by Eclypsium back in March and it’s a pretty simple authentication bypass, exploited by setting an X-Server-Addr header to the device IP address and adding an extra colon symbol to that string. Send this along inside an HTTP request, and it’s automatically allowed without authentication. This was assigned CVE-2024-54085, and for servers with the BMC accessible from the Internet, it scores that scorching 10.0 CVSS.

We’re talking about this now, because CISA has added this CVE to the official list of vulnerabilities known to be exploited in the wild. And it’s hardly surprising, as this is a near-trivial vulnerability to exploit, and it’s not particularly challenging to find web interfaces for the MegaRAC devices using tools like Shodan and others.

There’s a particularly ugly scenario that’s likely to play out here: Embedded malware. This vulnerability could be chained with others, and the OS running on the BMC itself could be permanently modified. It would be very difficult to disinfect and then verify the integrity of one of these embedded systems, short of physically removing and replacing the flash chip. And malware running from this very advantageous position very nearly have the keys to the kingdom, particularly if the architecture connects the BMC controller over the PCIe bus, which includes Direct Memory Access.

This brings us to the really bad news. These devices are everywhere. The list of hardware that ships with the MegaRAC Redfish UI includes select units from “AMD, Ampere Computing, ASRock, ARM, Fujitsu, Gigabyte, Huawei, Nvidia, Supermicro, and Qualcomm”. Some of these vendors have released patches. But at this point, any of the vulnerable devices on the Internet, still unpatched, should probably be considered compromised.

Linear Solar Chargers For Lithium Capacitors

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in this arena, they tend to have high parts counts, higher complexity, and higher cost than some alternatives. [Jasper] set out to test some alternative linear chargers called low dropout regulators (LDOs) for small-scale charging of lithium ion capacitors against those more traditional switch-mode options.

The application here is specifically very small solar cells in outdoor applications, which are charging lithium ion capacitors instead of batteries. These capacitors have a number of benefits over batteries including a higher number of discharge-recharge cycles and a greater tolerance of temperature extremes, so they can be better off in outdoor installations like these. [Jasper]’s findings with using these generally hold that it’s a better value to install a slightly larger solar cell and use the LDO regulator rather than using a smaller cell and a more expensive switch-mode regulator. The key, though, is to size the LDO so that the voltage of the input is very close to the voltage of the output, which will minimize losses.

With unlimited time or money, good design can become less of an issue. In this case, however, saving a few percentage points in efficiency may not be worth the added cost and complexity of a slightly more efficient circuit, especially if the application will be scaled up for mass production. If switched mode really is required for some specific application, though, be sure to design one that’s not terribly noisy.
