Kevin Rye has been working on his GPS clock project and wrote a detailed explanation on his blog describing the build: The great thing about setting the time and date via GPS is that I won’t have to put any buttons on the clock. It’ll set itself, and appear to be completely autonomous. By removing the buttons […]
Jason Dorweiler blogged about his autonomous car build: For the localization of the car I’ll be using a GPS sensor and accelerometer. First, the GPS will find the starting coordinates of the car. Then the car will start moving, somewhat blindly at first. Once the car is moving, data from the accelerometer and elapsed time […]
Crennsmind tweeted: With the help of a Bus Pirate and a PCI Express GPS module I saw on @hackaday, I finally have GPS Get an assembled Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors.
Todd Harrison, member of the Superstition Amateur Radio Club (SARC), posted this video by Steve Bowen: APRS and GPS networking, operations and theory This presentation does not cover how to setup and use Automatic Packet Reporting System (APRS) but does get into its origins, limits, functionality and usage.
Want to keep track of your trips from anywhere you are? Here’s a DIY GPS to SD-card data logger/compass by Ktulu: Earlier this year I have bought on the flea market a used car GPS system, an Amstrad gp1000. (Un)fortunately it was so badly damaged, that it could not be repaired, so I thought I would […]
Emeryth discovered that these cheap laptop PCI GPS modules can easily be interfaced with microcontrollers. On the back of the board there are testpoints which he identified as UART and USB. The USB is recognized as a CDC-ACM standard virtual COM port.
Brian writes: I made a single circuit board version of Arduiniana’s famous “Reverse Geocache” box lately. It is based off a PIC instead of an Arduino and incorporates all of the required electronics into one package, saving money and packaging space. The write-up also has a few good tips about the dangers of multiple power […]
At DEFCON 20, Fergus Noble and Colin Beighley discussed the basics of GPS operation and how hackers can access and use its data. They have developed and released a new set of tools which they hope will make GPS accessible to hackers and experimenters. These resources include a library, libswiftnav, which contains a complete toolset […]
Boris Landoni draws our attention to the GSM GPS shield for Arduino designed by Open Electronics. “The shield is 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. This new version has several new hardware features, that allow maximum customization […]
Epninety shows how to add GPS to a Tablet PC that doesn’t have one: A nice simple project, which made an otherwise tired tablet into a useful piece of kit, with the added benefit that when things go wrong off-road, at least it wasn’t in perfect condition to start with. Via the forum.
Jeremy built a tiny GPS receiver into a “Altoids” case. This unit is explained in the video above, but is basically a GPS receiver, 1 CR1220 battery for the RTC on the GPS breakout, one of my Square Inch of Goodness boards, one 128×32 OLED display, three 6mm buttons, and a 400mAh Li-Po Battery (from […]
Libelium has introduced their 3G/GPRS shield for Arduino (3G + GPS). It enables connectivity to high speed WCDMA and HSPA cellular networks, and includes GPS. “The GPS module also makes it possible to perform geolocation services even in indoors as it can work in A-GPS and S-GPS modes, so the location given by the GPS […]
Ezflyr’s GPS-based clock uses the GlobalSat EM-406 module to show the time with around 1 second accuracy. Here is a photo of the completed GPS Display Time Standard I intend to use for setting a variety of clock projects I’ve made, or am working on. This GPS module, the GlobalSat EM-406, has excellent sensitivity as […]
Boris suggests we look at this GSM/GPRS and GSM modem. A modem GSM & GPRS with SIM900 or SIM908 module. Allows you to create data connections on the GSM network through a standard USB interface. The cellular modems, particularly USB-stick ones, are now at very affordable prices, however they’re limited: they are explicitly designed for […]
Tyler of coobrolabs writes about his latest open source project, The Coobro Geo is an Arduino compatible through-hole GPS kit that allows you to navigate using only LEDs for direction and distance. It is built around the awesome Fastrax UP501 GPS module (MediaTek MM3318 chip). It is completely open source, so all design files and […]
The VPN1513 GPS Receiver Module is a newly released combination GPS receiver and Parallax Propeller mini dev board. It uses a SiRF Star III chipset capable of tracking up to 20 satellites. The module supports both “raw” output mode for raw NMEA 0183 strings and the default “smart” mode for specific user-selected data through a […]
Here’s a good video from Kevin Darrah for those new to GPS basics demonstrating how to interface the Parallax GPS module with the Arduino. Note that while this video is based on the discontinued PMB-248 module, Parallax indicates that their current PMB-688 module is pin compatible (as far as TTL interfacing is concerned) and will […]
Sahas Kata had a minor run in with the law, an officer claimed he was speeding, 40 in a 25. fortunately he was running tracking software on his new droid phone. once in court he asked the officer when he was last trained on use of the radar gun, when it was last calibrated, etc. […]
For his USC Rocket Propulsion Lab, Chris Fenton designed this project using a Picaxe 18X microcontroller which accepts a GPS NMEA data stream, pulls out the altitude and logs it to a 24LC512 external EEPROM. Upon recovery the data is then read from the EEPROM. Source code for the Picaxe and hand drawn schematic for […]
STMicroelectronics announces the impending release of Teseo II, a new generation of single-chip stand-alone positioning receivers for Portable Navigation Devices, in-car navigation and telematics applications. These Systems-on-Chips are monolithic devices capable of receiving signals from multiple satellite navigation systems, including GPS, GALILEO, GLONASS and QZSS. Listed features include 3rd generation positioning receiver with 32 tracking […]
