So a couple of years ago we had a pretty bad ice storm here on the east coast and there were thousands of homes left without power for a week or more. As with any disaster one can expect the criminals to come out of the woodwork and make a bad situation worse. Well as luck would have it my brother in law was one of the people that had their homes robbed while they “seeking shelter” elsewhere. Among the items stolen was their sons’ Sony PlayStation 3. Of course the requisite police report was filed and as is usually the case, none of his property was ever recovered.
Now someone can easily have an alarm system installed in their home which can deter some burglars, but let’s be honest, even the best alarm systems have “holes” in them. So I got to thinking, why spend the money on a home security system that might deter a burglar when we can catch the burglar instead and possibly get him off the streets.
I spoke with several law enforcement personnel and sure enough, video game consoles are one of the most popular items stolen from home break ins. So a quick search on Ebay showed several empty Sony PlayStation 3 cases in the $20 range that would work for my project.
Introducing the I2C GPS Shield, an Arduino based shield that gives the user the ability to access most of the commonly used GPS data using the I2C protocol. The shield features an ultra high sensitive -165dBm GPS receiver. The shield is directly compatible with the Diecimila, Duemilanove and Uno. The shield can also be modified to work with the Arduino Mega by removing two solder jumpers and soldering external wires to the SDA and SCL lines.
Standard GPS modules output NEMA 0183 data in serial format which then need to be read and parsed. While there are several libraries out there that will parse the data some users still have trouble incorporating the overall code into their designs.
As most people know Honeywell recently discontinued production on the popular HMC5843 3-Axis Magnetometer. Honeywell replaced it with the HMC5883L which has a better resolution, larger full scale range, consumes less power, comes in a smaller package and most importantly...it's much CHEAPER in price! Needless to say I placed a backorder for the parts in December and was pleasantly surprised when they arrived yesterday. I pulled out the prototype board I had made and proceeded to mount all the components. I placed the populated board in my handy reflow oven and a few minutes later...VOILA....we had a breakout board.
