How to find your car in a parking lot

The easiest way it to use smart phone with GPS locator. When you park, simply record your location and when you need to find it use navigator which guides you to its place. If you don’t have such phone and want to build one, follow msuzuki777 instructable where he builds car tracker. Device is pretty simple when building using modules. So here he uses Ublox NEO-6M GPS module, LSM303DLHC magnetometer, custom Arduino, Nokia 5110 LCD and Lithium battery. This locator simply remembers coordinates where your car is parked. When you need to find simply turn on and you will see how far you car is and what direction you need to go thanks to magnetic sensor based compass. You can find more uses of this devise. For instance when hiking – you can remember start location and let it guide you home when done. Continue reading

Arduino based GPS Distance Calculator

This project was done as a final year project by a group of students studying at the Indiana University. This type of application was particularly useful and made for Golf application. It works by recording latitude and longitude points of where the ball was hit from, and then calculate the distance from that location to wherever the ball lands. The project requires a basic Arduino with a GPS shield along with general purpose stationary. This system could also be modified to be useful in many different situations. Football teams could use this to keep an average distance for punted balls or field goals. An important thing by making the project is related to the GPS shield. When testing the GPS shield, you need to make sure that the device has a satellite fix, this can be observed by the flashing red light on the shield. A good project if you want to try but its application will be very limited. However it can be used in an application related to distance such as in a quadcopter or a fixed wing… Continue reading

GPS toy stacked in to cube

Karman has been busy with a GPS on-board computer for bicycle. In the beginning all he wanted was a speedometer but later it evolved in to feature packed cube of electronics. His nice clean design ended up with impressive parts list: 128×64 OLED display, Arduino Mini Pro, DC to DC converter, LiPo charger, savaged iPod-Nano battery, EM-411 GPS receiver and few discrete components like buttons, resistors and wires. Everything is packed in to 6 layer cube of about inch size. It is able to display current course, altitude, speed, time, traveled distance, coordinates. Adding decent enclosure it should fit on to bicycle pretty well. Or simply drop in to pocket when hiking. Continue reading

Feature rich scooter computer with touch screen

How about making a high tech scooter? It’s actually pretty easy to do with some extra cash. Well seems this project isn’t very cheap, but ads real value to regular scooter. So called Scooterputer has some hardware on it that is based on Arduino Duemilanove. First of all it has a touch screen – no need for buttons. Other things include: temperature sensor, DS1307 time and date RTC chip. Additionally there is an accelerometer and finally GPS and GSM chips. With this entire periphery computer is able to monitor battery voltage, track time and date, sense environment temperature, measure lean and gauge, track speed and trip distance. With GPS you get compass and position data. With GSM module Arduino is able to send SMS along with latitude/longitude data, heading, speed, and a time stamp data. Also GSM module acts as security system if unauthorized use of scooter is detected. Continue reading

High altitude balloon tracker with Arduino

Launching balloons to high altitudes become more and more popular. Probably there are several reasons to do so, including low budget, so almost any enthusiast can afford, simple equipment most of them made from DIY parts. Probably this list could go on and on, but main idea that it is real fun to reach nearer cosmos. In this project a balloon payload has a GPS tracker along narrow-band RF (434.650MHz) tracker that allows many enthusiasts to tune up to its frequency and help tracking the balloon. The heart of payload is Arduino board which takes care of Lithium cells and interfaces GPS and RF trackers. Continue reading
