Generally, “jammers” — which are also commonly called signal blockers, GPS jammers, cell phone jammers, wifi jammers, etc. are radio frequency transmitters that are designed to block, jam, or otherwise interfere with radio communications. A jammer can block radio communications on devices that operates on a given radio frequencies within its range (i.e., within a […]

If you love finding solutions that could widen horizons – that is something you will like! I wanted to know what my next ESP projects could connect to – and I decided to look for some open WiFis …. That is the result after two days programming – and 45 min walking arround. Only for testing this

Introduction This circuit is a repeater for GPS data. It is intended to connect to Garmin-38 (and similar) hand held GPS receivers that don’t have external antennas. The purpose for the repeater is to allow the GPS to be outside, exposed to the satellite view, and allow the user to see the data below decks

It’s no the first time that we present a localizer without GPS. We remake the old device with the cheaper SimCom module SIM900. In the previous post we present the GSM section and now we can present the complete localizator. Introduction This system allows for localization without directly using GPS technology; we are able to

Description This project combines a GPS receiver module, a MicrochipPIC microcontroller and a Secure Digital memory card to make a GPS data logger. With a large capacity and reasonably long battery life it is a very useful device for logging GPS position for example for mapping with OpenStreetMap. In this picture the complete GPS data

Speedometer is a speed measuring gauge used to calculate the speed of motor vehicles. They are mainly of two types- electronics and mechanical. Digital speedometer measures the speed and mileage in vehicles. Normally both types work on the principle of electromagnetism, however they have a disadvantage that they cannot be used if there are no

I have built a GPS Logger and it works very well to trace the drove route for two years. By the way, the navigation solution computed by GPS receiver itself has an excellent accuracy without DGPS because an intentional offset added by US goverment has been stopped several years ago. The position error seems to

Global Positioning System is based on satellite navigation technology. A GPS Receiver provides the accurate location of an object in terms of latitude and longitude. Accurate time calculation with respect to GMT can also be done by using GPS. For more information on different data obtained through GPS, refer GPS Receivers. Here a PIC microcontroller
