Frequency accuracy has been a topic of special interest to many amateurs and experimenters since the early days of radio. Until recently, the best frequency standard available to most hams was a crystal oscillator carefully adjusted to zero-beat with a.... -
This GPS receiver is powered by 2 AA batteries. They are only strong enough for the GPS to stay on for about two hours, and this seems like quite a waste. I would like to be able to use a larger battery, and sometimes even an AC adapter... -
The µPC8211TK, µPC8215TU, and µPC8226TK are silicon germanium (SiGe) microwave monolithic integrated circuits (MMIC) designed as low noise, high-gain amplifiers for GPS and mobile communications. These ICs are manufactured using our 50 GHz fmax UHS2 (Ultra....

This is a project that I started back late 2003 when I just starting to learn PIC programming. I wanted to building something that actually did somthing useful. This project is based on a PIC16F84. I actually came up with this idea and then after doing some.... -
The GPS interface can be fed in 2 ways: with a stabilized 5V supply or with a 10 to 25V unregulated DC supply. In both cases the power is fed into the RJ45 connector on point 8. Pin 7 is DC ground. The power supply current is first secured with a slow.... -
Some Garmin GPS receivers are capable of running off external power ranging up to +32VDC or more, whereas others can only accept a maximum of +8VDC...

The advent of new high-speed technologies and the growing computer capacity provided realistic opportunity for new cost effective technologies and realization of new methods of innovations. This technical improvement together with the need for high.... -
The GPS is based on 24 satellites located in six orbital planes at a height of 20 200 km and circle the Earth every 12 h. Each plane is inclined at 55 to the Earth’s equator and contains four satellites. The GPS positioning is based on oneway time-of-arrival.... -
The balloon went to 103, 258 ft peak reported altitude. Many items had to be considered for launching payload to this range. Unlike building an electronics package to operate at Sea Level, items such as air pressure, temperature, relative humidity and even.... -
New uTracker on GE865 Small size. New edition of tracker (SIM300DZ, EB-230/LEA-5S). Add OBD-II (ISO) sensor, accelerometer and RFID reader. Add TR24 2.4GHz module except USB link to host. Change all to SPI (free 3 pins to buttons ?) Add u-blox LEA-5S... -
The Rockwell Jupiter TU30-D140 is a OEM (Original Equipment Manufacterer) GPS receiver module that is designed to be implemented as part of a larger design, like a vehicle tracking system, navigational system, time/clock reference etc. This is a 12.... -
Shield for Arduino designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS. We begin with the supply circuit a simple LM7805. To work, it is necessary to provide an input.... -
In this project i have interfaced an GPS with AVR microcontroller, the ATtiny2313 gets the location from the GPS and display it over the LCD display... -
Following last year`s rediscovery of radio controlled flight, I`ve recently become enamored with the hacking/mod potential of the downright bargain priced 9-channel FlySky FS-TH9X transmitter (also sold as Turnigy/Eurgle etc). The original 2. 4GHz RF module.... -
This project is a GPS based clock, which also displays the present date, automatically compensates for daylight savings time, displays current speed, and maximum speed, along with your present heading in degrees with respect to true north. The original.... -

Some months ago I ordered a EM-406 GPS module from Sparkfun. I intended to explore geotagging and this module seemed to be a simple one to use : integrated antenna, SiRF III chipset (seems to be well know on forums) while not too expensive. You provide a 5V.... -
This project replaces the electronics in a standard quartz wall clock with a circuit that uses GPS satellites to get the precise time.... -
The GPS Car or Boat Computer can display a wide range of GPS related information for the driving or boating enthusiast. In this page you will find everything that you need to know to build the unit. This includes the design, schematic, parts list, PC board.... -
An embedded system which is used for tracking and positioning of any vehicle by using Global Positioning System (GPS) and Global system for mobile communication (GSM). In this project AT89S52 microcontroller is used for interfacing to various hardware.... -

The user interface will consist of a single button and several LEDs or a RGB LED through which all user communication will occur. An overview of the proposed system states and transitions is given below. Pressing the button will wake the device up from sleep.... -
Once you discover how to setup an RS232 connection, it`s really just cut-and-paste for future projects. Please note this is a relatively compact SMD version of the power supply. This can easily be obtained with through-hole components using a breadboard..... -
You`ve probably heard about the CP210x USB ICs from Silicon Labs, now here`s an application that uses it. The CP2102 gives us 3V TTL to a VCP (virtual comm port) over USB as well as generating the 3. 3V needed for the board. There are a couple things to.... -
