There’s a good chance that you use a MEMS accelerometer every single day. It’s the small chip that let your smart phone automatically adjust its screen orientation. They’re great chips, and since they’re mass-produced you can add them to your projects for a song (if you can abide the tiny packaging). But we have no idea [...]

[Chris Suprock] is interested in using technology to improve your accuracy with a firearm. To that end, he’s using an Accelerometer mounted to a gun to gather feedback about each shot. The hardware setup is pretty simple. We don’t have specific details, but it looks like he’s using a QFN accelerometer chip like you would [...]

[Kevin Osborn] is making it a bit easier for young programmers to write programs that interact with the physical world. The device he’s holding in the picture is an Arduino based accelerometer and distance sensor meant for the Scratch language. Scratch is a programming language developed at MIT. It has kids in mind, and focuses on [...]

[Viktor] doesn’t remember why he started this project. He doesn’t know what he had in mind in the beginning, nor what the intended use was.He knows he wanted something interactive with blue LEDs.  What he ended up with, was a 3 axis Accelerometer with a pretty cool display that sits on his desk to amuse visitors. [...]

We don’t have much personal experience with DOF hardware, but this Arduino library which reads and compensates for three-axis magnetometer and accelerometer data looks very impressive. It should work for existing hardware, but there’s also a demo design using a Honeywell HMC5883L compass and a Freescale MMA8453Q accelerometer which you can build yourself. Unfortunately these come [...]

This game of Space Invaders is played by tilting your iPhone to the left or right. It’s a demonstration of HTML5 used to link devices in-browser. The only setup that’s required is for the base device to load up a webpage, then the control device scans a QR code (or just types in a link) to [...]

[Boris Landoni] put together a guide to using an inexpensive 3-axis accelerometer with Arduino. The chip that he chose for the exercise is an MMA7455L made by Freescale. It’s got a lot of nice features packed into it, using hardware to do some of the things you’d need software for with other chips like reporting [...]

So we saw this tip come in and thought–oh, another POV device. We watched the video (embedded after the break), took a sip of coffee, then almost sprayed the beverage all over the computer when we realized that this uses a diy sensor to synchronize the POV image. [Ch00f] came up with the idea for [...]

This odd-looking ball can automatically take a panoramic image whenever you throw it up into the air. Seriously, that’s then entire set of operating instructions for the device. Inside, a 3D printed frame hosts an array of 36 cellphone cameras, each capable of taking a two megapixel image. Also included is an accelerometer. When it [...]

[desimon] had a wanted to use some accelerometer chips, but their 3x3mm 16-VFQFN packages made it pretty darn hard to solder by hand. While there are endless ways to approach this, we found this one peculiarity interesting from his use of a gas torch, though it is pretty much hot air reflow. A PCB for [...]

If you’ve ever wondered about the use of or theory behind or the use of accelerometers, this tutorial by Love Electronics is a very good resource. In this article, Love takes one through how to hook up an ADXL345 accelerometer and use it with a Netduino processor. Before the subject of hooking everything up is [...]

[Daniel] just made a motion controlled game controller to go with his infuriating game. Thankfully, [Daniel] posted the source for this game so first time players already know the level select codes. The controller is based on an Arduino Uno with what looks to be a Sparkfun 2-axis accelerometer providing the tilt sensing. A similarly [...]

We’ve already added the components needed to build [Rucalgary's] tiny POV device to our next parts order. The little device sets a new standard for tiny persistence of vision boards. Instead of relying on the user to find the best speed and timing for swinging the board around, [Rucalgary] used an accelerometer. This is the [...]

[Lars Kristian Roland] is using a wristwatch to control this rover. The bot itself is a utilitarian build with a gripper based on this Thingiverse project. As you can see in the video after the break, it’s got variable speed control based on accelerometer data from a TI ez430 Chronos wristwatch. The watch connects to [...]

[Lucas Fragomeni] is controlling this robot using the accelerometer on his Android phone (translated). He could have gone through our Android tutorials and developed a custom application but he took the shorter route and used Amarino, an ‘Android meets Arduino’ toolkit, to do it for him. [Lucas] combined an Arduino, a BlueSMiRF Bluetooth modem, and two servo [...]

The Segfault is a balancing transport similar to a Segway, but it uses analog comparators instead of digital circuitry. On board you’ll find no less than twelve LMC6484 op amps. They take signals from the gyroscope and the accelerometer, balance and filter them, then drive the motor h-bridges accordingly. [Charles], the guy behind the Segfault, is [...]

This video is a blatant example of having too many high-end toys but we love it anyway. [Robert Stephenson] is controlling a rather awesome-looking hexapod via a Bluetooth connection to his HTC Hero. The app allows on-screen selections to decide which portion of the robot will move as a result of accelerometer data from the [...]

[Elrik] converted an RC car so that it can be controlled with an Android phone. He wisely uses the accelerometer for steering with a button for forward and another for reverse. There’s even control for the headlights. The car itself has had a servo retrofit for steering but it’s the Bluetooth module that catches our [...]

Indeed, the gizmo above is meant to be used as a gas pedal. [Grant Skinner] came up with the idea to control slot cars using an Android phone as a gas pedal. He coded the software for the handset and a computer using Adobe AIR. Once connected, the computer is sent the accelerometer data from [...]

[Jerome Demers] sent us his extremely detailed semester project. The two part system consists of PICs connected to XBee modules and accelerometers. By using the device a coach can monitor an athlete and correct their minute mistakes. Did we mention [Jerome] was very detailed? He also goes into the particulars of designing the circuit, using [...]

[JP Carrascal] hacked his guitar by adding motion control while removing the need for wires. He’s using a dual-Arduino system with an Mini Pro inside the guitar and a Duemilanova for the receiver connected to a computer. Wireless is provided by the XBee module seen above and a gutted Wii remote accelerometer is in there [...]

You may remember seeing the golf glove air guitar hack last month. Here’s two more uses for gloves with sensors on them. On the left is a glove interface with flex sensors on each digit as well as an accelerometer. The VEX module reads the sensors to detect sign language as a command set. A [...]

Remote motion control This project walks though a method of controlling motors with an accelerometer when the two are physically separated. Two Arduinos are used, with the user interface and the motor control connected via Ethernet. This must be useful for something; maybe it should be the next step once you get your accelerometer up and [...]

Accelerometers make for nice user interaction, that’s why every Apple product seems to have one included and the Nintendo Wii is still alive despite its underpowered graphics capabilities. Adding one to your project is pretty simple, just a matter of reading in analog data and interpreting it according to the datasheet. If you’re just starting [...]

Shortly after finishing his Makiwara punching bag, [Abieneman] wired and programmed an Arduino to an accelerometer to find out just how much acceleration (and with some math, force) is behind his punches. The project is simple and would be quick to reproduce for your own measuring and experiments: all that he used included an Arduino, [...]

As we posted about [Atarity]’s XBMC hiding in an SNES controller, we were finishing work on a tutorial for [Adafruit]. The tutorial combines a Teensy USB development board with a 3D accelerometer inside of an SNES controller. The Teensy is programmed to poll the SNES controller buttons and read the accelerometer values. The buttons are [...]

This seems like something of a throwback hack. [WilinNeofoxx] has built an audio modem interface for use with his Android phone. A program running on the Android device takes the accelerometer data and converts it into a 9600bps audio signal, kind of like a dial-up modem. His custom circuit board takes that sound in through [...]
