Guitar Game Plays with Enhanced Realism

There’s a lot more to learning how to play the guitar than just playing the right notes at the right time and in the right order. To produce any sound at all requires learning how to do completely different things with your hands simultaneously, unless maybe you’re a direct descendant of Eddie Van Halen and thus born to do hammer ons. There’s a bunch of other stuff that comes with the territory, like stringing the thing, tuning it, and storing it properly, all of which can be frustrating and discouraging to new players. Add in the calluses, and it’s no …read more

Bluetooth Gun Safe Cracked By Researchers

Believe it or not, there are quite a few people out there who have purchased gun safes that can be remotely unlocked by Bluetooth. Now we can understand why somebody might think this was a good idea: the convenience of being able to hit a button on your phone and have your weapon available in the heat of the moment is arguably a big selling point for people who are purchasing something like this for home defense. But those with a more technical mind will likely wonder if the inherent risks of having your firearm (or other valuables) protected by …read more

Smart Station Runs Entertainment, Is Entertainment

It’s that special time of year—time for the parade of student projects from [Bruce Land]’s embedded microcontroller design course at Cornell. [Timothy], [Dhruv], and [Shaurya] are all into remote sensing and control applications, so they built a smart station that combines audiovisual entertainment with environmental sensing.

As with the other projects in this course, the smart station is built on a PIC32 dev board. It does Bluetooth audio playback via RN-52 module and has a beat-matching light show in the form of a NeoPixel ring mounted atop the 3D-printed enclosure. But those blinkenlights aren’t just there to party. They also …read more

A Bluetooth Speaker For Babies

[Mike Clifford] of [Modustrial Maker] had not one, not two, but five friends call him to announce that their first children were on the way, and he was inspired to build them a Bluetooth speaker with a unique LED matrix display as a fitting gift. Meant to not only entertain guests, but to audio-visually stimulate each of their children to promote neurological development.

Picking up and planing down rough maple planks, [Clifford] built a mitered box to house the components before applying wood finish. The brain inside the box is an Arduino Mega — or a suitable clone — controlling …read more

Uber, Vulnerable Banking Apps, and Bluetooth – Paul’s Security Weekly #539

 In the news, a new Windows evasion technique, naked rowers, undetectable malware, social engineering from your shed and banking apps vulnerable to MITM attacks. Paul’s Stories Uber Paid 20-Year-Old Florida Hacker $100,000 to Keep Data Breach Se… Continue reading Uber, Vulnerable Banking Apps, and Bluetooth – Paul’s Security Weekly #539

Light Switch For The Lazy

[Will Donaldson] has whipped up a quick hack for anyone thinking of dipping their toe into home automation — or otherwise detest flicking off the bedroom light before navigating their way to their bed: a remote control light switch!

This remote switch uses a sg90 servo, an Arduino Uno, and pairs of ATtiny85s with HC-05 Bluetooth modules assembled on protoboards. The 3D printed mount screws easily on top of a standard light switch cover while still allowing the switch to be flipped the old-fashioned way. It’s also perfect as a temporary solution — [Donaldson] is presently renting his apartment — …read more

Spice up your dice with Bluetooth

There’s no shortage of projects that replace your regular board game dice with an electronic version of them, bringing digital features into the real world. [Jean] however goes the other way around and brings the real world into the digital one with his Bluetooth equipped electronic dice.

These dice are built around a Simblee module that houses the Bluetooth LE stack and antenna along with an ARM Cortex-M0 on a single chip. Adding an accelerometer for side detection and a bunch of LEDs to indicate the detected side, [Jean] put it all on a flex PCB wrapped around the battery, …read more

Bluetooth Speaker In A Bag

[VanTourist] — irked by what he sees as complicated project videos — has demonstrated that you can build a high quality, multi-function Bluetooth speaker inside three hours.

Using simple hand tools — primarily a crimper, wire stripper, razor cutter and some glue — he’s packed this repurposed GoPro accessory bag with quite a bit of tech. The main components are a Bluetooth amplifier with a spiffy knob, and a pair of 15W speakers, but he’s also added a 1W LED flashlight, 1A and 2.1A charging ports, a battery charge monitor display, and pilot cover toggle switches for style points. Despite …read more
