Direct current (DC) by definition flows in one direction. Alternating current (AC), on the other hand, periodically changes direction, or reverses polarity. It is indeed possible for a portion of a circuit that is normally DC to periodically change direction, or reverse polarity like an AC circuit.
QR Code is a 2D barcode symbology capable of encoding all types of data, such as numeric, alphabetic characters, Kanji, binary, text, url etc. To build a qr code generator in Microsoft Visual Studio, we can use a qr code generator .NET DLL by Avapose.com and follow these steps:
Want to light the skies with your own flying saucer? Here's a quick way to add lights to an ordinary fribee using a cheap light-up yo-yo. It's so easy, anyone can do it.
Reduce the risk of blown fuses, blown sensors, shorted wires, and even possibly increase shift times on an automatic and possibly increase horsepower with a grounding kit! All you need is some wire, terminal ends and electrical tape or heat shrink. To make this work, all you have to do is run ground wires from essential components to a good ground area, such as the strut tower.

When I was attending college, my friends had a phantom thief in their dormitory. Almost every night, a different item of food would go missing, never to be seen again. There was constant speculation as to whom the thief was and how to catch them. Security cameras were deemed too invasive, but none could think of another method of surveillance... until today.
Overclocking is quite an awesome thing. When computer components are designed, they are made to run at a certain speed, otherwise known as their clock and bus speeds. These limits are not actually limits. You can overclock components, which essentially makes them go faster than their set limitations. This can save you a lot of cash when newer components come out and you don't have enough money to upgrade. However, when you overclock components, you must be careful and make sure that the machi...
If you're going to stop by the 2010 World Expo in Shanghia, China, you'll probably get sidetracked at one point or another. Any traveler to Shanghai will want to see The Bund. But if you don't know how to say "Bund" in the Shanghai language, you can kiss your site-seeing days "zeh wèh" (goodbye).
This Revit 2009 video tutorial covers how to add parameters for scheduling and tagging. In this case the objects being scheduled are parking spaces. The problem was that by default Revit is able to schedule the “count” of objects. We want to schedule stacker parking which meant every parking component equaled 2 spaces. In order to schedule the number of spaces, a shared parameter is added which looks for a yes/no parameter stating whether or not the component is a stacker. This is done by add...

The board has a lot of parts to it, so be sure to follow these instructions step by step as it meticulously details all of the essential components you'll need to wind surf. This tutorial also covers how to rig steer and tacking so you can change course as you wind surf. Terminology is also explained in this tutorial. A...
The guys at Poor Man Mods show you how to vent your hood to reduce engine bay temperatures, which can lead to lower intake temperatures and protection to components in your engine bay. To do this, they just take a few coupler nuts and screw them onto the studs on the hood where the hinge is. Doing so, they create about a 1 inch gap in-between the hinge and the hood itself, which raises the rear of the hood up, allowing hot air to escape. Near the turbo, this help reduce engine bay temps by 12...
This Revit software tutorial shows how to array a series of voids to create a changing truss system. Rather than thinking of the modeling in components what we are doing here is modeling a solid and using Revit’s cut geometry tool to slice a solid into stick members. The only catch to this techniques is that each truss has a slight slant on the top and bottom. This is something we can look past since it will be lost in the line weight. Once this model needs to transfer to a higher lever of pr...
In this Rhino tutorial we cover how to make an exponential curve with with Explicit History (Grasshopper). This is an intro to using scalar parameters in Rhino to driving geometry with math. Also covered, is how to use the range components in Rhino to make collections of objects, in this case points. By learning the simplest commands in Rhino, you can start to build on them and combine them for more complex results. This tutorial is best viewed at full screen. Make an exponential curve with G...
INTRODUCTION The everyday PC user doesn't think much about its PC and problems that can cause critical damage to their data or other stuffs stored on Hard drive and other electronic parts until the problem actually occurs. Once a failure happens, the repairs can be costly and very time-consuming and one also have to sacrifice their data stored on hard drives if the damage is more severe!
It is widely known that sticky rice is an essential staple in the Chinese diet. But did you know it also plays an important role in their ancient architecture?
Hello, Hackers/Viewers, Today's topic is going to be based on how to disable autorun for Removable Disks and Drives. Doing that is very easy, i you read the below!
I have an interest in using recycled materials in sculptures, particularly circuit boards and other wasted electronic and mechanical components with which I put together sprawling cities lit with fairy lights. These cityscapes can conjure an image of a parallel society built from what we throw away. Utopian or dystopian, the ‘Electri-Cities’ remain a feast for the eyes and the mind. What makes them particularly intriguing is the population of tiny model railway people—they bring a host of nev...
There is no fan experience in professional sports quite like watching an NBA game live. Partly, this can be attributed to the combination of fluid teamwork and jaw-dropping athleticism the players exude in the form of size, speed, jumping ability, grace, and strength. What truly differentiates the NBA from the spectators' perspective, though, is the figurative nakedness of the players. While the NFL buries its athletes beneath pads and masks, the NBA presents its talent in shorts and a tank top.
The PatchDeform modifier in 3ds Max deforms an object based on the contours of a patch object. This modifier works similarly to the PathDeform modifier, but uses a quad-based patch object instead of a spline shape or NURBS curve path. Patch Deform is a great tool for mapping geometry on a surface or the distribution of component on a surface in 3ds Max. The only catch is that the distribution geometry has to come from a surface originally made as a Patch. The surface cannot come from a set of...
In this Rhino video tutorial we cover how to make a sine and cosine curve with Explicit History (Grasshopper).

Grasshopper is a new plug-in that David Rutten is working on for Rhino. It has similar functionality to GC but at this point if not so component based. It is more like GC in that it uses features and stores them as nodes you can rearrange and change hierarchy’s. In this video David covers where to find the plug-in, how to install it and then the very (let me emphasize the VERY) basics of the interface. Learn how to install and get started using the Explicit History plug-in (also known as Gras...

I recently came across this amazing MIT media lab site, Kit-of-No-Parts. Though not directly related to the content Cory has been posting, it is an interesting "craft" approach to technology/science. The site was created as documentation of a student's thesis work in the High-Low Tech research group at the MIT Media Lab:
"Freezing Moments" is a great piece of video of different liquids dramatically reaching freezing point, directed by Andrey Muratov. It's cryptically described as "Components of the space. Between existence and 'No!'. Alive - Absorbs." Hmm. Client is also cryptic: GTLK (Gosudarstvennaya Transportnaya Lizingovaya Kompaniya). Appears to be Russian, which would translate to the "State Transport Leasing Company".
The Weston Price Foundation is the gold standard for truly good nutrition. Weston Price was a dentist practicing in the 1930s who over the course of many summers visited fourteen different native groups and correlated the health of their teeth to what they were eating. He consistently found that as long as the people ate their traditional whole foods diet, their teeth (and the rest of their bodies) were healthy. When they started eating Westernized foods their dental and overall health deteri...
