Arduino-Based Vehicle Tracker With GPS+GPRS

Homebrew tracking device was designed using an Arduino Uno and GPRS+GPS shield. Using it to track persons is highly illegal unless you belong to an alphabet agency.

LEDs Turn This Paper Map into a Tram Tracker

Public transit can be a wonderful thing. It can also be annoying if the trains are running behind schedule. These days, many public transit systems are connected to the Internet. This means you can check if your train will be on time at any moment using a computer or smart phone. [Christoph] wanted to take this concept one step further for the Devlol hackerspace is Linz, Austria, so he built himself an electronic tracking system (Google translate).

[Christoph] started with a printed paper map of the train system. This was placed inside what began as an ordinary picture frame. Then, [Christoph] strung together a series of BulletPixel2 LEDs in parallel. The BulletPixel2 LEDs are 8mm tri-color LEDs that also contain a small controller chip. This allows them to be controlled serially using just one wire. It’s similar to having an RGB LED strip, minus the actual strip. [Christoph] used 50 LEDs when all was said and done. The LEDs were mounted into the photo frame along the three main train lines; red, green, and blue. The color of the LED obviously corresponds to the color of the train line.

The train location data is pulled from the Internet using a Raspberry Pi. The information must be pulled constantly in order to keep the map accurate and up to date. The Raspberry Pi then communicates with an Arduino Uno, which is used to actually control the string of LEDs. The electronics can all be hidden behind the photo frame, out of site. The final product is a slick “radar” for the local train system.

Track Your Dog With This DIY GPS Harness

Have you ever wondered how far your dog actually runs when you take it to the park? You could be a standard consumer and purchase a GPS tracking collar for $100 or more, or you could follow [Becky Stern's] lead and build your own simple but effective GPS tracking harness.

[Becky] used two FLORA modules for this project; The FLORA main board, and the FLORA GPS module. The FLORA main board is essentially a small, sewable Arduino board. The GPS module obviously provides the tracking capabilities, but also has built-in data logging functionality. This means that [Becky] didn’t need to add complexity with any special logging circuit. The GPS coordinates are logged in a raw format, but they can easily be pasted into Google Maps for viewing as demonstrated by [Becky] in the video after the break. The system uses the built-in LED on the FLORA main board to notify the user when the GPS has received a lock and that the program is running.

The whole system runs off of three AAA batteries which, according to [Becky], can provide several hours of tracking. She also installed a small coin cell battery for the GPS module. This provides reserve power for the GPS module so it can remember its previous location. This is not necessary, but it provides a benefit in that the GPS module can remember it’s most recent location and therefore discover its location much faster.

Build a Touchless 3D Tracking Interface with Everyday Materials

Combine low-tech materials with some high-tech components and build a completely Touchless 3D Tracking Interface. Explore capacitive sensing by using several panels of cardboard lined with aluminum foil. These panels, when charged, create electric fields that correspond to X, Y, and Z axes to create a 3D cube. With the aid of an Arduino microcontroller and some supplied code, movements inside the cube are tracked as your hand moves around inside the field.

For Weekend Projects makers looking for an introduction to Arduino, this is a great project to learn from. Once you’ve gathered all your parts, this project should only take a couple hours to complete – you’ll be playing 3D Tic Tac Toe before the weekend is over!

Once your touchless 3D tracker is up and running, what you do with it is only limited by your own imagination! The original implementation of this project comes from media artist Kyle McDonald, who has suggested the following uses and applications:

  • Make an RGB or HSB color picker
  • Control video or music parameters; sequence a beat or melody
  • Large, slightly bent surface with multiple plates + a projector = “Minority Report” interface

Arduino geek develops Cold War Angst, starts spying on satellites (video)

Start with some Arduino and Gameduino hardware, add a splash of PLAN-13 satellite tracking software from 1983, and finish with a healthy dose of libertarianism. The result? A neat little hack called Angst, designed and built by Mark VandeWettering (aka Brainwagon). It can store details of up to 750 satellites on 128KB of EEPROM memory and display their predicted orbits in all the glory of SVGA. Don't get lazy though -- the most reliable way to track those pesky snoops in the sky is still to don your anorak, step outdoors and snoop right back.

Doh uses RFID and Arduino to help you remember your wallet, continues search for the 'Any Key'

If you can dream it, Arduino can help you build it -- perhaps with a dash of MakerBot thrown in for good measure. The latest homebrew project to hit the ol' inbox sounds an alarm whenever you leave a room without a registered item. Doh (named in Homer Simpson's honor, we presume), uses a trio of devices to track items that you usually travel with, like your keys or a cellphone. After you've assembled the rather complex contraption, you affix color-coded RFID tags to your gadgets, before registering them with the Arduino-based host. If you leave the room without all of the items that you've registered as a "grouping," a door handle-mounted display will indicate what's missing by flashing its color and sounding an alarm. If you've forgotten multiple items, the display will cycle through the associated colors. There's also a two-way "buzzing tag" that beeps until it's found, if you wish to add that to your collection. It's not a turnkey solution by any means, but unlike Homer, at least you're not being tasked with preventing nuclear meltdown. And if you're looking for a time-proven alternative, a pen and a pad of stickies should do. Jump past the break for a demo video, banjo-equipped soundtrack and all.
