Top 10 NEW Platform Games of 2015Geeks are Sexy Technology News. AC Waveforms : Basic AC Theory. When an alternator produces AC voltage, the voltage switches polarity over time, but does so in a very particular manner.
When graphed over time, the “wave” traced by this voltage of alternating polarity from an alternator takes on a distinct shape, known as a sine wave: Figure below Graph of AC voltage over time (the sine wave). In the voltage plot from an electromechanical alternator, the change from one polarity to the other is a smooth one, the voltage level changing most rapidly at the zero (“crossover”) point and most slowly at its peak. If we were to graph the trigonometric function of “sine” over a horizontal range of 0 to 360 degrees, we would find the exact same pattern as in Table below.

More... The S110 SoftDevice is precompiled, linked binary software implementing Bluetooth® 4.0 low energy (BLE) technology. Integration with proprietary chip-vendor software is not necessary because the S110 SoftDevice enables you to develop code as a standard ARM® Cortex™-M0 project, instead of within the code's framework.
Offered as a standard C language interface, the Application Programming Interface (API) gives the application complete compiler and linker independence from the SoftDevice implementation. The S110 SoftDevice implements Bluetooth 4.0 low energy (BLE) technology and is precompiled, linked binary software. System on Chip application with the SoftDevice.

Turn your EAGLE schematic into a PCB : Start placing the components. Now we need to move the components to (near) where we want them on the final board.
OR we want to move them to sensible places that will make the placement of traces easier. How to Use a Breadboard. Favorited Favorite 5 Introduction Breadboards are one of the most fundamental pieces when learning how to build circuits.

IP Addressing and Subnetting. One of the most intimidating but extremely important subjects on the CCENT/CCNA or ICND1 exam is subnetting.
If you started listening from basic IP addressing which is covered in our list of topics from the beginning and have understood everything, then you won't have any problem understanding subnetting. I'm going to try and explain subnetting as simply as possible and hope to answer all your questions. Cadsoft Eagle PCB design tutorial. This is a series of video tutorials about Cadsoft’s Eagle PCB design software.
Lesson 1. Microcontroller - Program Transfer Part 2 (Drivers) - A Beginners Guide to the Atmel AVR Atmega32. Microcontroller - A Beginners Guide - Transferring a Program into the Microcontroller Part 2 (Drivers) By now, you should have constructed the SPI interface.
If not, you can either review the previous tutorial, or live with the flimsy wires. If you have read the first sentence more than two times after constructing the device I presented in the last tutorial, don't worry...the thing you made is the SPI interface! It's simply the 6-pin cable, wired to a straight set of 6 pins that match the proper pin arrangement on the microcontroller. At this point though, we need to make sure the computer will recognize the programmer. Since I am installing the driver on my computer running the Windows 7 64-bit operating system, the installation is somewhat different than the procedure for the 32-bit operating system. Here are the general steps to get the drivers on the system, and the programmer recognized by either a 32-bit or 64-bit Windows operating system. How to Use a Breadboard. Biblioteki EAGLE 6.x.x.

Now that we've specified the size of our new pad (0.6 x 0.6 mm in this case), it's time to place it in our package. This is where you really need to have a bit of attention to detail, since pad size and placement is critical to creating a functional and manufacturable footprint! Selecting the 'Smd' tool (the red box in bottom of the the left-hand toolbar), and adjusting the 'Smd Size' to 0.6 x 0.6 on a mm grid, we should see something similar to the following if you zoom in or out a bit:
Biblioteki EAGLE 6.x.x. Using EAGLE: Board Layout. Favorited Favorite 1 EAGLE’s board designer is where a good portion of the magic happens. It’s here where the dimensions of the board come together, parts are arranged, and connected by copper traces. In the board editor, the conceptual, idealized schematic you’ve designed becomes a precisely dimensioned and routed PCB.
In this tutorial we’ll cover every step in EAGLE PCB design: from placing parts, to routing them, to generating gerber files to send to a fab house. Using EAGLE: Board Layout. Favorited Favorite 1 Create a Board From Schematic If you haven’t already, click the Generate/Switch to Board icon – – in the schematic editor to create a new PCB design based on your schematic: The new board file should show all of the parts from your schematic.
