Collaborate Disseminate
Over the last year or so, we’ve seen an explosion in the popularity of cyberdecks — those highly portable and occasionally wearable computers that would make William Gibson proud. A lot of the cyberdecks we see are based on NUCs or the Raspberry Pi and are essentially post-apocalyptic DIY laptops. …read more
The CAN bus is a rich vein to mine for a hacker: allowing the electronic elements of most current vehicles to be re-purposed and controlled with ease. [MikrocontrollerProjekte] has reverse engineered a CAN bus media and navigation controller and connected it to an STM32F746G-Discovery board. The STM32 is in turn connected to an Android phone, and allows the media controller to trigger a large number of functions on the phone, including music playback, maps, and general Android navigation.
When reverse engineering the controller, [MikrocontrollerProjekte] employed a variety of approaches. A small amount of information was found online, some fuzzing was …read more

Have an ESP8266 development board such as the NodeMCU or Wemos D1? You’re currently reading Hackaday, so probably. Got an Android device kicking around? Also seems fairly likely. In that case, you should check out ESP8266 Loader by [Bluino Electronics]. This recently released application lets you not only flash new binaries to any ESP8266 board using the FTDI, PL2303, CH34X and CP210X USB chipsets, but also offers a serial monitor for debugging on the go.
You’ll need a USB OTG cable to get your ESP board jacked in to your Android device, but you don’t need root or even to …read more
[Jason Gin] recently wrote in to tell us about his adventures replacing the eMMC storage chip on a cheap Windows tablet, and we have to say, it’s an impressive amount of work for a device which apparently only cost him $15. Surely much better pieces of hardware have been tossed in the trash for less serious failures than what ailed his DigiLand DL801W tablet. We’d love to see the lengths this guy would go to restore something a bit higher up the food chain.
As any good hacker knows, you can’t fix the problem until you understand it. So the …read more

Every hacker has a USB thumb drive on their keyring, filled with backup files and a way to boot up a broken computer. One feature that most are missing though is USB On The Go (OTG) support, which allows a USB device to act as a USB host, connecting to devices like cell phones and tablets.
That can be added with the addition of a USB OTG adapter, though, and [usbdevice] has produced a nice how-to on soldering one of these permanently into a USB thumb drive to create a more flexible device. It’s a simple solder-something-on-something-else hack, but it …read more
USB On-The-Go (OTG) is one of the fun aspects of the USB standard. There are feelings about the other aspects, but that one is alright. Regardless, [Francesco] realized one day that the £3 digital picture frames he purchased at a charity sale really didn’t care if the files on the thumb drive mysteriously changed all the time. It would just keep pulling and displaying the latest file at a blistering 0.2 frames per second. That’s right, the concept [Francesco] went after is to show changing data, even animations, with an update of one frame every five seconds!
His initial tests …read more
