Fresh hacks every day
Now you can prove that you have the bumpiest commute in the office by measuring how rough your ride actually is. [Techbitar] calls the project the Bump-O-Meter. It uses an Arduino, GPS, and accelerometer to map out rough roads.
The hardware was built on a breadboard and [Techbitar] goes into detail about connecting and communicating with each module used. … Read the rest
When schools and universities have hundreds of students in a lecture course, they need a way to tell alumni and other potential benefactors that faculty/student relations are just as good as they were in the 1960s, when enrollment was just a fraction of current levels. Technology solves all problems, apparently, so administrators of these universities turn to ‘clickers’ – radio … Read the rest
There’s a new Arduino in town, this time designed in conjunction with Adafruit. It’s the Arduino Micro, a very neat little board designed for breadboard use.
Ostensibly an upgrade of the long in the tooth Arduino Nano, the new Micro takes all the best features of the new Arduino Leonardo and shrinks them down to a convenient stick … Read the rest
Here’s an inexpensive Arduino-based MP3 Jukebox (translated) which [Jose Daniel Herrera] put together.
He spent some time making sure that it looked great sitting on a shelf with his other audio equipment. This started with a wooden box which is some reused packaging. We’re not familiar with the ‘iNFUSiONES’ product; perhaps it’s tea or tobacco? At any rate, … Read the rest
Never one to pass up the recycle pile at work, [Scott] usually doesn’t find much. A few old hard drives, maybe a ancient laptop every once in a while, but on very rare occasions he finds something actually useful. This latest haul is a gaggle of stepper motor drivers that, with a bit of work, can be reverse engineered and … Read the rest
Google+ Hangouts provide a group video chat with the ability to add apps. [RobotGrrl] created a Node.js web app to control an Arduino that can be added to a Hangout.
There’s a Javascript client that runs inside of the Hangout and communicates with the Node.js server running on an EC2 server over WebSockets. The server receives this client data and … Read the rest
The Arduino IDE is extremely similar to C++, but judging from the sketches you can find on the Internet, you’d never know it. Simpler Arduino projects can make do with just toggling IO pins, reading values, and sending serial data between two points. More complex builds fall into the category of real software development, and this is where the standard … Read the rest
