How To Build a Home Automation System with Raspberry Pi and Arduino. We’ve talked about the relative merits of Arduino and Raspberry Pi before – they each have their strengths.
Tempest (codename) TEMPEST is a National Security Agency codename referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations. TEMPEST covers both methods to spy upon others and also how to shield equipment against such spying.
The protection efforts are also known as emission security (EMSEC), which is a subset of communications security (COMSEC). The NSA methods for spying upon computer emissions are classified, but some of the protection standards have been released by either the NSA or the Department of Defense. Protecting equipment from spying is done with distance, shielding, filtering and masking. The TEMPEST standards mandate elements such as equipment distance from walls, amount of shielding in buildings and equipment, and distance separating wires carrying classified vs. unclassified materials, filters on cables, and even distance and shielding between wires/equipment and building pipes.
System & hardware benchmark, monitoring, reporting. Install and Remove Since version 1.51, CPU-Z includes an installer.
The installation offers several advantages in comparison to the stand-alone version : The installation creates program entries in the start menu and on the desktop. It installs the right binary (x32 or x64) depending on your system. Installation Run the setup executable file, and let it guide you for the installation process. Removal. Project web – sourceforge. Philips unveils poleless street lighting system. FreeStreet is a suspended street lighting system, that doesn't require streetlight poles Image Gallery (4 images) A group of people including city planners and architects recently put a challenge to Dutch electronics company Philips: design an outdoor lighting system that helps to declutter our streets.
The result was FreeStreet, a street lighting system that does away with vertical streetlight poles in favor of horizontally-strung cables that have clusters of LED lights built into them. IBF-Wiki.

Indtil de tragiske oversvømmelser i Thailand var priserne faldet til 400 kroner pr. terabyte. Arduino. Hassock Hog motor controller description. The micro-controller was the "brain" of the robot controller, and as such it had to do a lot of tasks to do.
Some were going to be extremely time critical such as accurately measuring the width of the receiver pulses and sending pulses to the motor drive MOSFETs, while others could be fitted in as and when time allowed. I was hopeful that my choice of micro-controller was a good one, but it was only because of a few pertinent feature that the micro proved that it could handle all the tasks I needed it to. The critical features of the micro-controller were: Being able to write interrupt driven machine code routines that could be directly embedded into the main C program Interrupt capability from I/O lines as well as presetable timers Interrupt priority assignable to individual events Pre-loadable timers and data port registers Cooperative multi-tasking operating system Real time clock source Interrupt routines Pulse jitter Motor speed routine Receiver pulse validation Fail-safe operation.

Connecting a Parallax GPS module to the Arduino (Adapted from Igor Gonzalez Martin's Spanish language tutorial here.)
This tutorial shows how to connect a Parallax GPS module to the Arduino, and how to use Arduino code to read information like date, time, location and satellites in view from the standard NMEA data streams that the module produces. Hardware Connections: The module connects to the Arduino through a 4800 bps TTL-level interface (8 data bits, no parity, 1 stop bit, non-inverted). Only four wires are needed to read the module's GPS data. Note: if you are using an Andruino Uno, keep in mind that you can't use the GPS module at the same time as your computer is connected on the USB port.
(photo and drawing by Igor Gonzalez Martin) Understanding NMEA GPS strings GPS modules typically put out a series of standard strings of information, under something called the National Marine Electronics Association (NMEA) protocol. Each of these sentences contains a wealth of data. Sean Carney's Website. A fully functional GPS receiver with the ability to display the current location, heading, speed, average speed and maximum speed, the distance traveled, the bearing, distance and ETA to a way-point or coordinates, and the date and time.
Description This is a sketch to interface an Arduino, SparkFun GPS Shield, digital compass (optional), and Nuelectronics LCD Keypad Shield together in a useful way, providing all the functionality of older commercial GPS receivers. The sketch provides four modes of operation: current location, heading and speed; distance traveled, average and maximum speed; bearing, distance and ETA to a set of coordinates or a way-point; and the date and time.
In addition, up to 20 way-points can be saved with names, so you can build a library of locations you have visited or plan to visit later.
