DIY enthusiasts can build their own smart car with simple kits like building blocks, controlled with Bluetooth 4.0 joystick or app.

With simple communication protocol, the car can achieve human-computer interaction.

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.

 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.

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.

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 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.

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)” research project is pursuing these aims. The idea is to electronically network vehicles and infrastructure by means of car-to-X communication. A fleet of 120 vehicles fitted with the system developed by the simTD consortium is about to demonstrate how this works in practice on the highways, rural and urban roads in and to the north of Frankfurt am Main over several months.

BYU-student-built electric car sets land speed record at Salt Flats – [via]

An electric car designed and built by BYU engineering students set a world land speed record for its weight class, averaging 155.8 mph over its two required qualifying runs, one of which was clocked at 175 mph.

The milestone marks the end of a seven-year quest of more than 130 students, led by Perry Carter, who just retired as an associate professor.

“This is a wonderful closure to 31 years of teaching at BYU and many projects,” Carter said after the record was certified. “But this is the one that takes the cake. I’m done.”
