If there’s one thing that can trigger people, it’s the printer racket. Printer manufacturers who put DRM-like features into their consumables are rightly viewed as Satan’s spawn, and while these monsters have been content so far to only put digital rights management features into their ink and toner cartridges, they appear to now have their rapacious gaze set on print media too. At least according to the good folks over at the Electronic Frontier Foundation, who claim that Dymo’s latest generation of label printers will have RFID tags in the label cartridges, apparently to prevent consumers from buying non-Dymo media. The company doesn’t bill it as a way to lock you into their exorbitantly priced consumables, of course; rather, this is an exciting new feature that’s called “Automatic Label Recognition,” which keeps track of what labels are installed and how many are left. Of course, this is just red meat to people like us, and we fully expect to see workarounds in the not-to-distant future.
This problem only applies to 4K Blu-ray discs with DRM. Presumably any 4K discs without DRM will still play, and of course you can still play the DRM discs on older Intel processors. Do you have a collection of DRM 4K Blu-ray discs, and if so, do you play them via your computer or a stand-alone player?
There is no negative impact on print quality when using consumables without electronic components.
It’s well known that many printer companies make their profit on the consumable cartridges rather than the printers themselves. And most printers require consumers to only use factory original cartridges, a policy enforced by embedded security ICs. Use a third-party ink cartridge and your printer will likely refuse to print. There are legitimate concerns about poor quality inks damaging the print heads. But with reports like this 2003 one from the BBC noting that 17% to 38% additional good quality pages can be printed after the consumable is declared “empty”, and that the price per milliliter of inks is seven times the cost of vintage champagne, one can reasonably conclude that these DRM-protected consumables are more about on ensuring profits than protecting the hardware.
For now, this announcement applies to German customers, and covers the Canon imageRunner family of multi-function printers (the complete list is in the company announcement above).
Regular readers will likely remember the Inkplate, an open hardware electronic paper development board that combines an ESP32 with a recycled Kindle screen. With meticulous documentation and full-featured support libraries for both the Arduino IDE and MicroPython, the Inkplate makes it exceptionally easy for hackers and makers to write their own code for the high-quality epaper display.
Now, thanks to the efforts of [Guy Turcotte], the Inkplate family of devices can now boast a feature-rich and fully open source ereader firmware. The project started in October of last year, and since then, the codebase has been steadily updated and refined. Nearing its 1.3 release, EPub-InkPlate has most of the functions you’d expect from a modern ereader, and several that might take you by surprise.
For one thing, [Guy] has taken full advantage of the ESP32 microcontroller at the heart of the Inkplate and implemented a web server that lets you manage the reader’s library from your browser. This allows books in EPUB v2 and v3 formats to be uploaded and saved on the Inkplate’s SD card without any special software. There’s currently support for JPG, PNG, BMP, and GIF images, as well as embedded TTF and OTF fonts.
As of this writing EPub-InkPlate supports both the six and ten inch Inkplate variants, and uses the touch pads on the side of the screen for navigation. While it’s on the wishlist for the final 1.3 release, the project currently doesn’t support the Inkplate 6PLUS; which uses the backlit and touch compatible displays pulled from Kindle Paperwhites. With shipments the new 6PLUS model reportedly going out in November, hopefully it won’t be long before its enhanced features are supported.
With the rising popularity of ebooks, it’s more important than ever that we have open hardware and software readers that work on our terms. While they may never compete with the Kindle in terms of units sold, we’re eager to see projects like EPub-InkPlate and the Open Book from [Joey Castillo] mature to the point that they’re a valid option for mainstream users who don’t want to live under Amazon’s thumb.
For more than a few years now, we’ve been covering the saga of tractors from the larger manufacturers on which all components are locked down by software to the extent that they can only be replaced by officially sanctioned dealers. We’re thus pleased to see a couple of moments when the story has broken out of the field of a few farmers and right-to-repair geeks and into the mainstream. First up: a segment on the subject from NPR is worth a listen, as the US public radio station interviews a Montana farmer hit by a $5k fuel sensor on his John Deere as a hook form which to examine the issue. Then there is a blog post from the National Farmers Union, the body representing UK farmers, in which they too lay out the situation and also highlight the data-grabbing aspects of these machines.
Has it really come to this? Are we really at the point that dishwashers have proprietary detergent cartridges that you’re locked into buying at inflated prices?
Apparently so, at least for some species of the common kitchen appliance. The particular unit in question goes by the friendly name of Bob, and is a compact, countertop unit that’s aimed at the very small kitchen market. [dekuNukem] picked one of these units up recently, and was appalled to learn that new detergent cartridges would cost an arm and a leg. So naturally, he hacked the detergent cartridges. A small PCB with an edge connector and a 256-byte EEPROM sprouts from each Bob cartridge; a little reverse engineering revealed the right bits to twiddle to reset the cartridge to its full 30-wash count, leading to a dongle to attach to the cartridge when it’s time for a reset and a refill.
With the electronics figured out, [dekuNukem] worked on the detergent refill. This seems like it was the more difficult part, aided though it was by some fairly detailed specs on the cartridge contents. A little math revealed the right concentrations to shoot for, and the ingredients in the OEM cartridges were easily — and cheaply — sourced from commercial dishwashing detergents. The cartridges can be refilled with a properly diluted solution using a syringe; the result is that each wash costs 1/75-th of what it would if he stuck with OEM cartridges.
For as much as we despise the “give away the printer, charge for the ink” model, Bob’s scheme somehow seems even worse. We’ve seen this technique used to lock people into everything from refrigerator water filters to cat litter, so we really like the way [dekuNukem] figured everything out here, and that he saw fit to share his solution.
The original PlayStation might be pushing 30 years old now, but that doesn’t mean hackers have given up on chipping away at it. A new exploit released by [Marcos Del Sol Vives] allows users to run copied games on all but the earliest hardware revisions of this classic console, and all you need to trigger it is a copy of Tony Hawk’s Pro Skater 2.
Aptly named tonyhax, this exploit uses a classic buffer overflow found in the “Create Skater” mode in Tony Hawk 2, 3, and 4. When the game sees a custom character saved on the memory card it will automatically load the name field to show it on the screen, but it turns out the developers didn’t think to check the length of the name before loading it. Thanks to this oversight, a long and carefully crafted name can be used to load an executable payload into the console’s memory.
The name contains the memory address of the payload.
That payload could be anything, such as a homebrew game, but in this case [Marcos] went all in and developed a simple tool that unlocks the console’s optical drive so it will play games burned to CD-Rs. Once the tonyhax exploit has been loaded, you simply swap the authentic Tony Hawk disc for whatever burned title you want to play. So far every game tested has worked, even those that span across multiple discs.
[Marcos] is providing not only the save files ready to load on your PlayStation memory card (either through a PC tool, or with the help of a hacked PS2), as well as the complete source code for tonyhax. This opens the door to the exploit being used to load other tools, emulators, and indie games, but as the PlayStation homebrew scene is relatively limited when compared to newer consoles, the demand might be limited.
Compared to the traditional physical modifications used to play copied games on the PlayStation, this new software approach is far more accessible. Expect to see memory cards with this exploit preinstalled hit your favorite import site in the very near future.
