The GPS tracking device is composed of a microcontroller, GPS module, cell module, and batteries all housed in a 3D printed case. The microcontroller is programmed to communicate with both the cell module and GPS module. When the GPS module is not within a user-specified boundary, the device will send a text message alert. We made a device that can track people suffering from Alzheimer’s and Dementia could greatly benefit the quality of life of both that person suffering and the caretaker.

Positioning is an increasingly important part of an embedded design as more and more devices become mobile. Adding this capability into equipment that has to be smaller, lighter and have longer battery life is a major challenge. At the same time there are the challenges of implementing an effective wireless design with high performance and low power, while meeting the requirements of the project timeline and the certification authorities.

These challenges are being addressed by a new generation of wireless modules that are using the latest miniaturization technologies to make use of the various global positioning systems (GPS) around the world, with the footprint of GPS modules falling dramatically over the last few years.

F3GCWWGI8765XR5.MEDIUMDo you often forget where you have parked your car? With the help of this project you are able to locate your car with the push of a button. It’s using a GPS module to find the location and an LCD screen to display the distance and direction of your car.

When you park your car, you press the button, car tracker calculates the car location GPS coordinates and stores them in EEPROM so the car tracker can be turned off. When you’re leaving a store looking for your car, the car tracker reads the new GPS and displays how far from your car you are and points in the direction of your car.

Ugifer wrote this instructable detailing the build of his Arduino based high-altitude balloon tracker:

The tracker is based upon the Atmel ATMeag328 Microcontroller which forms the heart of many of the popular “Arduino” boards. We are going to make an “Arduino Compatible” board which we can program using the Arduino IDE.
Because the GPS module and SD card both require 3.3v and we have plenty of computing power, we may as well make the whole tracker run on 3v3. That means that we can’t clock the ‘328 up to its full 16MHz but it will run happily at 8MHz on 3v3, and that’s plenty for our purposes.

Kevin Rye’s GPS clock project :

I’ve been working on this clock for a long time, and a lot of effort has been put into it. I’ve learned so much from this project. I do have to admit some parts of the code aren’t as elegant as they should be, but it works. With the code complete, all that’s left to do is try my hand at designing a 3D printed joystick for the 5-way switch.

Today we’ll be talking about Captain Herrmano’s Mystery Box, a piece of hardware that I built over a year ago. But what is this box, what does it do, who was it built for and who is this Captain Herrmano anyway? This will be the topic of this article.
What is Captain Herrmano’s Mystery Box?

The box is a so-called “reverse geocaching puzzle”. The inspiration for this project was a reverse geocaching box built in 2009 by Mikael Hart. Unlike Mikael’s version of the box, it’s not enough to simply find and visit the target place. To unlock the treasure of Captain Herrmano, the player has to solve more tasks.

The special thing about this box is that it interacts with the player, and not just via text – it also has sound and light feedback, as well as other means of communication. But more about that later.

So who is this captain anyway? Captain Herrmano is an old pirate, whose spirit guards the chest and guides the player through the challenges. The chest, in turn, contains the pirate’s treasure.

This project is to build a portable GPS geared towards runners (well, me and what I think a runner wants a GPS thingy for). It’s sponsored by the University of Minnesota’s ECE Envision Fund.

The hardware is basically complete, and the software is functional, if not polished. This is what the main screen looks like while tracking, with another image to show scale (though you can also reference the microSD card in the images further down):

SC16C2552BIA44

With the rapid development of GPS (Global Positioning System) techniques, GPS gets wider application in many fields. GPS has features such as high precision, global coverage, convenience, high quality, and low cost. Recently, the use of GPS extends speedily from military to civilian applications such as automobile navigation systems which combine the GPS system, e-map, and wireless network. GPS is getting popular, and the market for GPS techniques is extending continuously.

UARTs provide serial asynchronous receive data synchronization, parallel-to-serial and serial-to-parallel data conversion for both the transmitter and receiver sections. These functions are necessary for converting the serial data stream into parallel data that is required with digital systems. Synchronization for the serial data stream is accomplished by adding start and stop bits to the transmit data to form a data character. Data integrity is ensured by attaching a parity bit to the data character. The parity bit is checked by the receiver for any transmission bit errors.

The circuit describes how to combine GPS into a navigation system by using a Philips 2-channel UART, the SC16C2552B. The SC16C2552B is a two channel Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data, and vice versa. The UART can handle serial data rates up to 5 Mbit/s.

F*watch is a fully open electronic watch project featuring an integrated GPS receiver.
The development started at CERN as an after-work project to make a special present for a retiring colleague who likes hiking and timing.
The full design (electronics, mechanics and software) is available under free licenses and the design is exclusively made with free tools.
