PIC16F88 Delorme Tripmate GPS Logger This project focused on creating a simple serial data logger for the Delorme Tripmate (also known as the GPSTripmate). The Tripmate is an older GPS receiver that can be purchased on eBay for <$20.The plan was to create a GPS data logger that would record the position of the unit and allow to read back the latitude and longitude after acquiring the data. [via] DIY - GPS Camera attachment This is a great how-to on building a GPS system for your DSLR camera. The pictures are tagged with the exact GPS coordinates for later reference. Nice work! This version eliminates the need for the expensive MC-35 and even the special 10-pin connector. I’ve opted for a quick GPS receiver and encased everything in a small black box with a flash shoe mount. Because it is powered through the camera’s power source, a switch on the side of the box turns off the GPS. Version 3 should include a battery, rechargeable through a USB connection. [via] UberTracker - Real-time GPS tracking unit It’s not quite small enough to track your cat, but the Uber Tracker is a beast of a product. This device may seem simple enough: get GPS coordinates and broadcast those coordinates over the cellular network - but it’s so much more! The Uber Tracker has open firmware and hackability. It’s also completely PTCRB and FCC certified meaning it is fully licensed to operate on any GSM network in North America. Configure the unit, power it up, and you’ll get an update every few minutes of the device’s position to your phone, your website, or your SQL database. Could you track your car? Sure. Ever wonder where your donated clothing goes? What about biological samples? It’s ‘big brother’ - but you get to play the older sibling’s role Traffic Message Channel receiver This project used to display and report the main roads traffic status and incident. Here are some features :Dual display: colour road map (left) and detailed text messages (right) both with LED backlight,Up to 120 TMC messages are stored in memory,Auto/manual TMC message scrolling,GPS position locator/follower optional,Map navigation with mouse sensor and/or micro joystick,Map zoom 10km to 80km (in 10km steps) City and area presets preconfigured,High quality NXP TEF6901AH chip used for best performance,Integrated RDS/RBDS radio data demodulator. [via] Open GPS Tracker The Open GPS Tracker is a small device which plugs into a $20 prepaid mobile phone to make a GPS tracker. The Tracker responds to text message commands, detects motion, and sends you its exact position, ready for Google Maps or your mapping software. The Tracker firmware is open source and user-customizable. The current supported hardware platform is… GPS-based universal clock generator Almost all commercially available GPS OEM modules provide a 1pps output, synchronized with GPS time. This pulse could be used as a reference to generate accurate high-frequency clocks, but special design has to address the short-term jitter affecting the 1pps signal. As a general guideline, an oven-stabilized crystal oscillator who guarantees the short-term stability is synchronized with the GPS 1pps for the long-term accuracy. Evaluation board using the ET312 SiRF III GPS receiver The evaluation board using the ET312 SiRF III GPS receiver is finally done! This board will allow you to play with this very small but powerful GPS receiver. HALO2 High Altitude Balloon Another successful high altitude balloon flight with some gorgeous images. Alexei writes: High altitude ballooning is an emerging hobby, since the price of GPS and communications equipment has gotten quite low. It is an excellent hobby for people fascinated by space flight and telerobotics and has many learning aspects — from systems design to electronics design to software engineering. There is also an exciting risk factor, namely, that you could lose your precious electronics if something malfunctions. In this project, many of my interest and knowledge areas came together. Also, I have verified that the Earth is indeed round and that space is black. GPS to SD-Card Data Logger This project combines a GPS receiver module, a Microchip PIC 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. GPS LCD Display Project The circuit it’self is pretty simple, take in the data on one pin, parse it, format it and then display it to a 4×20 LCD module (Hitachi Chipset). That is the basic idea, but you might add in somthing like a mechanical encoder that would allow for changing options or changing settings in the display unit. This might be as simple as a SPDT (Singe Pole Double Throw) switch if the options are as simple as two settings. [via] |
