About Nuts and Volts Magazine
Now In Our 30th Year! The first issue of Nuts & Volts was published in 1980. It was originally designed as a newsprint, all advertising publication that was mostly given away. Over the next few years, the magazine continued to grow in readership and advertising, however, not much changed until February 1992 when NV was changed to a tabloid format and started to make the shift to a more content-oriented publication. New editorial features were added along with monthly columns and projects for electronics DIYers. Since then, it has grown into one of the most popular and relevant magazines for the electronics hobbyist in the nation. Beginning with the January 2003 issue, Nuts & Volts was reformatted from a tabloid size back to a standard magazine size. now averages about 100 pages and is printed on high-quality paper in full color.

Feature & Project Articles
Past issues have included articles on Printed Circuit Board Prototyping, the Global Positioning System, Amateur Radio Topics, Audioanimatronics, MIDI Interfacing, CNC, Home Automation, Computer Control, Data Acquisition, PLUS Software Reviews and all types of Build-It-Yourself Electronic Projects.

This topic will be updated daily for more issues

CadSoft Eagle Professional 5.7.0 Full

Thursday, February 25, 2010

EAGLE (Easily Applicable Graphical Layout Editor) is an ECAD program produced by Cadsoft in Germany.It is very commonly used by private electronics enthusiasts,
because there is a very usable free demo version for nonprofit use and is available in English and German.
Cadsoft has released versions for Microsoft Windows, Linux, and Mac OS X. EAGLE provides a schematic editor, for designing circuit diagrams and a tightly integrated PCB layout editor, which automatically,starts off with all of the components required by the schematic. Components are manually arranged on the,board, with the help of colored lines showing the eventual connections between pins that are required by,the schematic, to aid in finding a placement that will allow the most efficient track layout. It also,provides a good auto router, which once the components have been placed will attempt to automatically find,an optimal track layout to make the electrical connections. It does not always manage to find a way of,routing all the signals, although it permits manual routing of critical paths such as power and high
frequency lines before letting the auto router handle the other connections.

How to Convert a Netbook Into a Touchscreen PC

Tablet PCs may be the next big thing in computers, but netbooks are cheap and widely available now. Why wait for Apple (or TechCrunch) to do it for you? Here's how to make your own touchcreen PC, starting with an off-the-shelf netbook.

By Anthony Verducci

Published in the January 2010 issue.

By outfitting an off-the-shelf netbook with a touchscreen, we were able to make our own finger-friendly PC.

If the buzz is to be believed, 2010 will be the year of the touchscreen tablet PC, with multiple major manufacturers lining up products that they claim will give us a carry-anywhere way to read e-books, watch movies and surf the Web.

And while I suppose I could just buy one of these machines, I thought it’d be more fun to make my own touchscreen PC out of last year’s “it” computer: the lowly netbook. The advantage: Unlike these new tablets, my creation would also have a keyboard, making it far more practical for typing-heavy tasks like e-mail and running Word. The project’s total cost: less than $500, including the computer.

First, I needed to gear up. I bought a Lenovo IdeaPad S10-2 netbook (retail price: $350) and a Hoda Technology Solderless Touch Screen Kit ($96 from fidohub.com), which contained everything I‘d need to transform a netbook into a touch-friendly tablet. Hoda offers a variety of models that are designed to fit specific netbooks, so make sure you get the right one if you try this at home.

I wanted to be sure the new touchscreen was properly protected, so I purchased a BodyGuardz transparent scratch-proof skin, which is designed to protect touchscreens without impairing their sensitivity. Before covering the new panel, I gave it a once-over with a can of compressed air—otherwise, dirt and dust could be forever trapped under the BodyGuardz.

Taking the PC Apart

Next came the fun part. In order to wire in the new screen, I first needed to disassemble much of the netbook. I started with the easy stuff: I removed the battery, unscrewed the underbelly screws and took out the hard drive. Removing the keyboard and screen bezel was a bit trickier—they had to be pried off with a filed-down plastic knife (plastic is less likely to scratch than metal).

If you decide to take on this project, open the screen and look for a seam that runs along the side, around the entire machine, either just above or just below the USB slots. Using the knife (or a similar tool), gently pry into this seam until the case begins to separate. With the underbelly screws removed, this should be very easy. To take apart the screen bezel, look for a similar seam along the side of the display, and use the knife to pry it apart as well. The bezel should pop right off.

Of course, the new touchscreen needed to get its power from somewhere. The kit comes with an internal USB power control hub—basically a USB hub that is installed inside the computer. This hub needs to be crammed inside the machine, which can be tricky with a cramped netbook (mine fit just above the computer’s Wi-Fi card). From there, it feeds power from the motherboard to the screen. After the hub is hooked up, it will actually have two unused internal USB cords. These are free to deliver power to components. I took one and attached a Kensington Bluetooth USB Micro Adaptor (one of the smallest Bluetooth dongles on the market), giving my netbook the ability to wirelessly

Placing the Panel

Now it was time to attach the touchscreen panel. The new screen has to be placed on top of the old one with perfect alignment. To do this, I put the battery back in the computer and turned the screen on, allowing me to see the LCD’s exact borders. One side of the new touch panel comes coated with adhesive, so I pressed this side into place over the lit-up screen. After I restarted the computer, the touchscreen was working—and I was able to accurately control the cursor with my finger. But it’s smart to give it a test run before you put the computer back together—just to be sure everything is in place.

While the laptop was open, I thought it couldn’t hurt to add some upgrades—more RAM and a faster and higher capacity storage drive will help a previously sluggish netbook stave off obsolescence, at least for a little while. I upgraded my machine to 2 GB of DDR2 SDRAM and a solid-state storage drive. I was now done and ready to put it all back together again —a fairly straightforward procedure. The final product: a powerful, portable, touch-friendly computer. Did it let me do anything a normal PC couldn’t do? Not really, although that could soon change, now that developers have the ability to build touch capabilities directly into Windows 7 applications. But it did let me move away from the netbook’s cramped touchpad and keyboard and spread my hands over a spacious touchscreen. And it certainly draws stares when I pull it out at a Starbucks.

Wireless Charging Station

We showed you the Duracell incarnation of this idea a couple of months back, now there is another player in the game and its name is the Powermat. It comes in either a simple desktop form or a folding portable version, but in either case it is a mat that can charge up to 3 gadgets using magnetic induction. For the system to function all devices require a proprietary jacket or add-on, but it is a small requirement for the simplicity it brings. They even have a pretty funny commercial you can check out after the jump.

Lesson 1 .... Introduction.

Saturday, February 20, 2010

Welcome to the start of the PIC Tutorial. These pages will take you form the basic structure of the device, right through to programming methods and techniques. Also, there will be suggestions on how to modify the code so that you can adapt the PIC to suit your applications within Cybot. We will not be including any internal architecture diagrams, as this may only lead to confusion. If you want to look at the datasheet, then this can be downloaded from Microchips' web site.

Microchip PIC 16F84 Microcontroller

Microchip manufacture a series of microcontrollers called PIC. You can see the range of their microcontrollers here. There are many different flavours available, some basic low memory types, going right up through to ones that have Analogue - To- Digital converters and even PWM built in. We are going to concentrate on the 16F84 PIC. Once you have learnt how to program one type of PIC, learning the rest is easy.

There are several ways of programming the PIC - using BASIC, C, or Assembly Language. We are going to show you the Assembly Language. Don't be put off by this. There are only 35 instructions to learn, and it is the cheapest way to program the PICs, as you do not need any extra software other than the freebies.

The 16F84 Pins

Below is a diagram showing the pin-outs of the PIC 16F84. We will go through each pin, explaining what each is used for.

RA0 To RA4
RA is a bidirectional port. That is, it can be configured as an input or an output. The number following RA is the bit number (0 to 4). So, we have one 5-bit directional port where each bit can be configured as Input or Output.

RB0 To RB7
RB is a second bidirectional port. It behaves in exactly the same way as RA, except there are 8 - bits involved.

VSS And VDD
These are the power supply pins. VDD is the positive supply, and VSS is the negative supply, or 0V. The maximum supply voltage that you can use is 6V, and the minimum is 2V

OSC1/CLK IN And OSC2/CLKOUT
These pins is where we connect an external clock, so that the microcontroller has some kind of timing.

MCLR
This pin is used to erase the memory locations inside the PIC (i.e. when we want to re-program it). In normal use it is connected to the positive supply rail.

INT
This is an input pin which can be monitored. If the pin goes high, we can cause the program to restart, stop or any other single function we desire. We won't be using this one much.

T0CK1
This is another clock input, which operates an internal timer. It operates in isolation to the main clock. Again, we won't be using this one much either.
