3G + GPS shield for Arduino

This is a new 3G shield for Arduino that gets you WCDMA and HSPA connectivity. Just like most smartphones these days the module also includes an internal GPS receiver which uses A-GPS and S-GPS modes for a fast time to first fix.

As Arduino enthusiasts already know the there are no limits to what you can build and this GPS + 3G shield takes that to a whole new level with super fast connectivity.

One of the features of this Arduino shield is that it can also work thanks to its A-GPS and S-GPS modes which means the location from GPS through NMEA sentences is completed with the cell information provided by both the 3G module and external Internet Geoposition Servers.

Here are some of the other features:

  • WCDMA and HSPA 3G networks
  • Internal GPS for Assisted A-GPS and Supported S-GPS modes
  • Video Camera (640×480)
  • Audio Kit including microphone, speaker, hands free and headphones available
  • SD file system up to 32GB
  • Works as a standard 3G modem
  • Send and receive mails by POP3/SMTP
  • Play compressed audio files

This will cost you €149 here.

find home machine uses GPS and LEDs to guide you home

This is a “Find Home Detector” as labeled by the developer and it is designed to show the way home by indicating direction with a light. Components include LilyPad board, a GPS receiver, compass and some LEDs. Simply it uses the GPS to get a position fix and figure out the direction to your house. The compass then comes into play to figure out your heading so it can light up the correct LED towards your home.

We have talked about other Arduino powered GPS projects here at Navigadget and this is definitely a nice addition to that list.

NAVI - Navigational Aids for the Visually Impaired

Just a couple of days ago we talked about MapBag, a messenger bag that helped you navigate the city with the help of a GPS receiver and 8 vibration motors with the LilyPad Arduino microcontroller. Today we come across a similar project called NAVI implemented by students at University of Konstanz in Germany. They also used a Arduino microcontroller but also added a Microsoft Kinect to the mix, attached to a helmet. Their plan is to help navigate visually impaired by providing vibro-tactile feedback that recreates the room’s layout.

Obviously it is far from being commercialized to be actually useful for the visually impaired but this is not bad for proof of concept.

Check out the video above.


What is this you may ask. It is (part of) a messenger bag with integrated GPS receiver that gives you directions via series of 8 vibration motors sewn in. The way it works is MapBag contains a microcontroller (LilyPad Arduino), a GPS chipset, and the eight vibration motors we just mentioned. The microcontroller constantly evaluates your current heading and the location of magnetic North or the location of the point of interest. Then microcontroller activates the vibration motors to inform your body of the compass reading.

I guess it takes a while to get used to but after the learning curve it sounds it becomes natural.

After using the MapBag for a few weeks, the slight pulses used to convey heading information have become second nature. Most importantly, I no longer find myself using street signs or depending on landmarks to discern my position in the city’s grid.


DIY GPS logger and tracker

If you are into DIY GPS gadgets of various kinds we got a new project for you.

This new GPS logger uses an Arduino board and has supports different GPS receiver modules. On the backside of this board is an SD card slot where it can record the coordinates in a simple text file. The total runtime of course depends on your battery and it can vary from 5 to 20 hours depending on how often you want to get position updates. There are some good instructions on this site including example code… Read More …
