This project used to display and report the main roads traffic status and incident. Here are some features ual 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.

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]

This project came about because of a need to accurately calibrate the piles of HP test equipment I have been buying off ebay. This project uses a 10mhz voltage tuned crystal oscillator whose frequency is locked to the GPS positioning system clock. The GPS I used was a Canadian Marconi (CMC) Superstar single board OEM GPS receiver with a Motorola external amplified GPS antenna. The ovenized crystal oscillator is a modified Anritsu MH4100A standard crystal oscillator. [via]

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.

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…

This GPS based car speed and position logger is based on Olimex LPC2148 project board, which is wired to GPS receiver. GPS receiver is interfaced via serial port – so not much of soldering.
Software is based on FreeRTOS where ChanFS file system is used for storing logged data in SD/MMC FAT16 formatted card. It also has USB serial port emulation which enables to monitor NMEA sequences or simply retrieve logs as from mass storage device without removing CD/MMC card. Project files for WinARM GCC can be downloaded here. [via]

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]

Here’s a how-to on building a low cost vehicle tracker using the Telit GM862-GPS module. The GM862-GPS is a hardware module that supports connections on local GSM networks as well as GPS signals. In addition, this device supports a Python interpreter which allows for easy interfacing to build a simple tracker. Lots of info at the below link. [via]

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.
