Pwnie Express open sources IoT and Bluetooth security tools

Posted on by

Pwnie Express announced the availability of open sourced versions of its Blue Hydra and Android build system software. The release of these tools enable comprehensive Bluetooth detection and community based development of penetration testing Android devices. Bluetooth detection is critical for effective device threat detection and must cover both Low energy (LE) and Classic Bluetooth standards. Blue Hydra has also been integrated into Pwnie’s monitoring platform, Pulse, to provide continuous Bluetooth visibility and threat detection … More → Continue reading Pwnie Express open sources IoT and Bluetooth security tools→

DIY Smart Home Device Means No More Fumbling in the Dark

Posted on by

Smart home tech is on the rise, but cost or lack of specific functionality may give pause to prospective buyers. [Whiskey Tango Hotel] opted to design their own system using a Raspberry Pi and Bluetooth device connectivity. Combining two ubiquitous technologies provides a reliable proximity activation of handy functions upon one’s arrival home.

The primary function is to turn on a strip of LEDs when [Whiskey Tango Hotel] gets home to avoid fumbling for the lights in the dark, and to turn them off after a set time. The Raspberry Pi and Bluetooth dongle detect when a specified discoverable Bluetooth …read more

Bluetooth and Arduino Vaporizer Upends Stoner Stereotypes

Posted on by

Back in the day, stoners were content to sit around, toke on a joint, mellow out, and listen to the Grateful Dead or something. Nowadays, they practically need a degree in electrical engineering just to get high. [Beiherhund] sent us his VapeBox build. Like so many projects on Hackaday, we’re not going to make one ourselves, but we appreciate a well-done project.

First off, there’s a home-built induction heater. A 30A current sensor and switch-mode power supply regulate the amount of juice going to the coil that surrounds the heating chamber. [Beiherhund] discovered that brass doesn’t have enough internal resistance …read more

Robomintoner Badminton Bot To Defeat Amateur Humans

Posted on by

Watching robots doing sports is pretty impressive from a technical viewpoint, although we secretly smile when we compare these robots’ humble attempts to our own motoric skills. Now, a new robot named Robomintoner seeks to challenge human players, and it’s already darn good at badminton.

This is not the first time we see a racquet attached to an omnidirectional motion platform or a racquet attached to a linear motion gantry, but it’s the first time we see this special combination of both. The clever design allows the robot to move autonomously over the entire playing field on its omnidirectional wheels, …read more

Broadcasting Bluetooth Beacons With Bubbles

Posted on by

Bluetooth beacons have only been around for a few years, but the draw is incredible. With Bluetooth beacons, your phone is location aware, even with location services are turned off. They’re seen in fast food joints, big box retailers, and anywhere else there’s a dollar to be made. [Nemik] has been working on a home automation project, and came up with a use for Bluetooth beacons that might actually be useful. It’s a WiFi-based Bluetooth beacon notifier that scans the area for beacons and forwards them to an MQTT server.

[Nemik]’s ‘Presence Detector’ for Bluetooth advertisements is actually a surprisingly …read more

Hackaday Prize Entry: Selfie Bot Let’s You Vlog Hands Free

Posted on by

[Sergey Mironov] sent in his SelfieBot project. His company, Endurance Robots, sells a commercial version of the bot, which leads us to believe that in a strange and maybe brilliant move he decided to just sell the prototype stage of the product development as a kit. Since he also gave away the firmware, STLs, BOM, and made a guide so anyone can build it, we’re not complaining.

The bot is simple enough. Nicely housed hobby servos in a 3D printed case take care of the pan and tilt of the camera. The base of the bot encloses the electronics, which …read more

Hackaday Prize Entry: Dtto Modular Robot

Posted on by

A robot to explore the unknown and automate tomorrow’s tasks and the ones after them needs to be extremely versatile. Ideally, it was capable of being any size, any shape, and any functionality, shapeless like water, flexible and smart. For his Hackaday Prize entry, [Alberto] is building such a modular, self-reconfiguring robot: Dtto.

To achieve the highest possible reconfigurability, [Alberto’s] robot is designed to be the building block of a larger, mechanical organism. Inspired by the similar MTRAN III, individual robots feature two actuated hinges that give them flexibility and the ability to move on their own. A coupling mechanism …read more

Hackaday Prize Entry: DIY Foot Orthotics

Posted on by

What does your gait look like to your foot? During which part of your gait is the ball of your feet experiencing the most pressure? Is there something wrong with it? Can you fix it by adding or removing material from a custom insole? All these answers can be had with an expensive system and a visit to a podiatrist, but if [Charles Fried] succeeds you can build a similar system at home. 

The device works by having an array of pressure sensors on a flat insole inside of a shoe. When the patient walks, the device streams the data …read more

Crowdfunding: A Wireless Oscilloscope

Posted on by

One of the most ingenious developments in test and measuring tools over the last few years is the Mooshimeter. That’s a wireless, two-channel multimeter that can measure voltage and current simultaneously. If you’ve ever wanted to look at the voltage drop and power output on a souped up electrified go-kart, the Mooshimeter is the tool for you.

A cheap, wireless multimeter was only the fevered dream of a madman a decade ago. We didn’t have smartphones with Bluetooth back then, so any remote display would cost much more than the multimeter itself. Now this test and measurement over Bluetooth is …read more
