How Many Hacks in an LED Display?

Posted on by

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or picture for the display, he’s wired the output of a Bluetooth speaker directly to the Arduino, and sends it speaker tones that encode the text to draw. And as if that wasn’t enough, he’s hacked a quartz driver board from an analog clock to use the display as a clock as well.

Let’s start with the LED matrix display, perhaps the best excuse for trying …read more

Mitosis: Anatomy of a Custom Keyboard

Posted on by

Ergonomic. Wireless. Low-latency. Minimalist. Efficient. How far do you go when you design your own open-source keyboard? Checking off these boxes and providing the means for others to do so, Redditor [reverse_bias] presents the Mitosis keyboard, and this thing is cool.

The custom, split– as the namesake implies — mechanical keyboard has 23 keys on each 10 cm x 10 cm half, and, naturally, a custom keymapping for optimal personal use.

Upper and lower PCBs host the keys and electronic circuits respectively, contributing to the sleek finished look. Key caps and mechanical switches were ripped from sacrificial boards: two Waveshare …read more

Hackaday Prize Entry: Safety Glasses Are Also Hands-Free Multimeter

Posted on by

It seems like the multimeter is never easy to see during a project. Whether it’s troubleshooting a vehicle’s electrical system and awkwardly balancing the meter on some vacuum lines and the intake manifold, or installing a new solar panel and hoping the meter doesn’t fall on the ground while the leads are in both hands, it seems like there’s never a good way to see the meter while actually using it. Some meters have a small magnet and strap that can be used to hang them temporarily, but this will only get you so far.

How possible would it be for an attacker to sniff the pairing process in Classic Bluetooth?

Posted on by

Classic Bluetooth protects its connection by keeping the pairing process secret. How does Classic Bluetooth prevent the keys from being sniffed during the pairing process? On what channel does the pairing process occur?

Is Ubertooth able to sniff traffic for more than one device for both classic bluetooth and BLE?

Posted on by

With tools like kismet,ubertooth-follow and ubertooth-btle, is it possible to sniff all bluetooth traffic for all devices at any given point in time? From what I understand, it is not possible since you need to follow the hop… Continue reading Is Ubertooth able to sniff traffic for more than one device for both classic bluetooth and BLE?→

Ever hear of the Ford Cylon?

Posted on by

OK, we haven’t heard of a Ford Cylon either. However, there is now a Mustang Cobra out there that has been given a famous Cylon characteristic. [Monta Elkins] picked himself up an aftermarket third brake light assembly, hacked it, and installed it on said Mustang.

The brake light assembly contains 12 LEDs, which unfortunately, are not individually addressable. Additionally, by the looks of it, the brake light housing was not meant to be opened up. That didn’t get [Monta] down though. There’s more than one way to skin a cat, but he chose to use a hot knife to open …read more

New report warns of connected-car security dangers

Posted on by

Securing the connected, smart and increasingly autonomous cars of tomorrow against hackers and criminals will only get harder as the computerized and constantly communicating ecosystem for connected vehicles expands to take in smart road infrastructure, smart homes and smart cities. That’s the warning in “Observations and Recommendations on Connected Vehicle Security,” a new paper from the Cloud Security Alliance, a tech-focused industry group that studies security issues and promulgates best practices. The authors were lead by Brian Russell, who is the chairman of CSA’s Internet of Things Working Group and the chief engineer for cybersecurity solutions at Leidos. They note that a connected vehicle’s attack surface only gets larger as automakers add more navigation, engine-control and entertainment systems inside the car, and society adds more smart devices and connected infrastructure outside of it. “Within a system-of-systems such as the CV ecosystem, there are many points of interconnectedness. A compromise of any one of these points potentially offers attackers the […]
