CarTracker – GPS Car locator

F3GCWWGI8765XR5.MEDIUMDo you often forget where you have parked your car? With the help of this project you are able to locate your car with the push of a button. It’s using a GPS module to find the location and an LCD screen to display the distance and direction of your car.

When you park your car, you press the button, car tracker calculates the car location GPS coordinates and stores them in EEPROM so the car tracker can be turned off. When you’re leaving a store looking for your car, the car tracker reads the new GPS and displays how far from your car you are and points in the direction of your car.

Simple automatic car battery charger

15258113394_07f1d693cf_z-600x398

Dilshan Jayakody has published a new build, an automatic car battery charger:

This is modified version of commonly available automatic car battery charger system. I obtain original layout of this charger from one of the commercially available Chinese car battery charger and modified some of the sections of original schematic to improve the performance and stability of the system. This charger is mainly based on LM311 comparator and 2×12V 4A transformer.

Custom OBD II Gauge in With OEM Look

by JustinN1 @ instructables.com:

 I built a custom OBD II gauge in the clock of my Subaru BRZ (GT86, FRS) and a lot of people wanted me to build them one. Here is how you can build one of your own. My wife is about to give birth to our second son and all the code is open source, so I have nothing to lose by posting this.

CxemCAR 1 – Android Control RC Car over Bluetooth

This is a open source project of RC Car with control from Android Phone via Bluetooth. The controller is used with .NET Micro Framework: FEZ Panda II, but you may use any controller works with .NET Micro Framework core (Netduino, GHI Electronics board’s and other). All source code is available at GitHub.

Car tires harvest energy

Imec and Holst Centre announce that they have made a micromachined harvester for vibration energy with a record output power of 489 µW. Measurements and simulation show that the harvester is also suited for shock-induced energy harvesting in car tires, where it could power built-in sensors. In a tire, at 45 mph, the new device can deliver a constant 42 µW, which is enough to power a simple wireless sensor node. These results, obtained within the research centre’s program for Micropower Generation and Storage, are presented at the 2011 IEEE International Electron Devices Meeting (IEDM) in Washington (December 7-9).

Imec’s innovative harvester consists of a cantilever with a piezoelectric layer sandwiched between metallic electrodes, forming a capacitor. At the tip of the cantilever a mass is attached, which translates the macroscopic vibration into a vertical movement – putting strain on the piezoelectric layer and generating a voltage across the capacitor. As piezoelectric material, AlN (aluminum nitride) was chosen. The harvesters are packaged with a 6-inch wafer scale vacuum packaging process. The micromachining production process is compatible with low-cost mass-production fabrication. [via]

Freescale introduces intelligent sensor for car battery monitoring

Freescale Semiconductor introduced the MM912J637 intelligent battery sensor (IBS), which accurately measures the voltage, current and temperature of lead-acid batteries and calculates the battery state, all while operating in harsh automotive conditions. The ability to accurately assess these battery parameters is becoming more important with increases in the number of hybrid vehicles on the road and overall electronic content in vehicles, as well as the introduction of start-stop systems.

Intelligent cars alert each other to hazards

The largest field test for vehicle-to-vehicle and vehicle-to-infrastructure communication (car-to-X communication) worldwide is about to get under way. Scientists, auto makers and communication companies as well as public-sector institutions have teamed up to develop a system that allows cars to share information on traffic conditions and impending hazards. The aim is to promote a safer, more efficient flow of traffic. Researchers from the Technische Universität München (TUM) are currently involved in devising the test scenarios that 120 vehicles will use to put the system dubbed simTD through its paces on Germany’s roads next spring.

Notice traffic blocks before they are visible. Recognize risky situations before they get out of hand. Reach your destination on time, safe and relaxed. The “Safe and Intelligent Mobility – Test Field Germany (simTD)
