My mobile rig, a Kenwood TM-D710E, needed a GPS receiver for APRS use. The GPS-710 wasn`t readily available and, besides, is quite expensive. I therefore decided to build my own. I found a Royaltek RGM-3600 GPS receiver on eBay for less than £20. This is a.... -
GPS modem is a device which receives signals from satellite and provides information about latitude, longitude, altitude, time etc. The GPS navigator is more famous in mobiles to track the road maps. The GPS modem has an antenna which receives the satellite.... -

CD-ROM 48X RF AMP Chip is RF pre signal processor and processes signals from optical pick-up. This chip processes main signal through summing amp, AGC block, EQ block, and generates SERVO error signals for SERVO control. It CAN playback CD-ROM and CD-RW.... -
The PB1009K is a silicon monolithic IC developed for GPs receivers. This IC integrates a full VCO second IF Filter 4-bit ADC and digital control Interface to reduce cost and mounting space. In addition, its power consumption is low. Moreover, use of a TCXO.... -
Abstract: The MAX1896 MAX1973 and MAX8863 combine to deliver 5V at 225mA, 1. 8V at 220mA, and 3. 3V at 60mA from a USB port. The schematics, BOM and performance data appear below. USB devices draw power from the USB port. The voltage is 4. 5V to 5. 25V and.... -
An L7805 provides a 5v rail. The input and output of the reg is bridged by a 470 F and a 10 F capacitor respectively to try and smooth things out a bit. The 5v rail created by the L7805 then powers the MAX232 level shifter and the GPS module itself. Thee.... -
As shown in the block diagram above, the 10 MHz signal is produced by an oven-stabilized 10 MHz crystal oscillator that is locked by a phase-locked-loop circuit (PLL) against the precision 10 kHz signal generated by the GPS receiver module. In addition to.... -

A plot showing the paths of the recently-tracked and currently-tracked satellites. The receiver`s location is the "bull`s eye" in the center while the top of the plot represents the North pole. The red line shows the "EFC" value - the setting of the.... -
This has been supplanted by the SD library built into the Arduino IDE. The only good thing about it is that it will (barely) fit and run into a `168 Arduino so if you happen to be stuck with a `168 and can`t upgrade, this code may be handy. Otherwise, please.... -
This application note presents alternate RF matching networks for the MAX2653 SiGe LNA, tuned for the GPS band (1575MHz center frequency). Performance metrics (supply current, forward gain, NF, IIP3, reverse isolation and input/output return loss) for both.... -
Complete GPS solution using MAXIM CMOS RF front-end receiver MAX2742 and SONY GPS baseband CXD2932 is presented.... -
This application note presents the component values and measured performance for the MAX2681 mixer IC when tuned for GPS operation at 1575MHz.... -
The actual anti-theft system is equipped with two frequency siren and connected to a vehicles immobilizer system. But in the laboratory simulation model; the change of operating modes, triggering of the siren and cutting off of the fuel supply to the engine.... -
The Global Positioning System (GPS) relies on more than two dozen GPS satellites orbiting the Earth. Each satellite transmits signals including a very precise clock plus satellite position information that allows a GPS receiver to determine its location,....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -

The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
