Add Wireless Charging to Your Smartphone *** FOLLOW THESE INSTRUCTIONS AT YOUR OWN RISK *** take safety precautions and do not do anything you are not certain of. i cannot be held responsible to any damage you may cause to your device or to yourself ! (now, after i covered my ass, we can begin) there are a few projects similar to this one on the net. I've drawn ideas from everywhere and incorporated some of my own. the whole concept and basic design is based on Palm's technology (although there are other manufacturers offering similar solutions). the Touchstone is a Palm charging dock meant for the Palm Pre smartphone, which supports wireless charging via a separately sold back cover. there are a few wireless charging technologies made by different manufacturers that all rely on the same physical concept but they are not cross-compatible, you cannot mix coils and docks (I've tried).

Best way to approach learning .NET Guitar to AV Receiver Interface The input stage of this amplifier circuit is a Common Collector amplifier which has high input impedance, low output impedance, and high current gain. The output stage is a Common Emitter amplifier which has medium input and output impedance, and high power gain. The input and output is decoupled from the 3V DC supply power by C1, C2 & C3, R1 & R3 control the base current of Q1 & Q2, and R2 & R4 control the output current of each transistor stage respectively. I used point-to-point construction for this circuit, however it could be built on a PC board if desired. I used aluminum duct tape to form power rails on the inside of the acrylic case. Since the tape can't be soldered I used small pieces of tape to fasten the connection points to the components. Parts List: Standard AV RCA phono plug on center spacing is 13mm with a 10mm panel mount hole.

10 common traps and mistakes in C# 1) Using the wrong type of collection .Net has a lot of collection classes and they are all specialized on specific tasks. Make sure to select the right one with care. Making the wrong choice can make your code inefficient, have unexpected consequences as well as making your code's intent unclear. Read more here: 2) Not using yield return When enumerating over objects for another caller you should use yield return instead of creating a return collection. 3) Parsing ambiguous dates Be sure to specify a format provider when you parse ambiguous dates. var date = DateTime.ParseExact("01/12/2000", "MM/dd/yyyy", null) 4) Rethrowing Exceptions with an exception instance If you want to catch and rethrow an exception, be sure to use the simple throw; syntax. catch(SomeException ex){ logger.log(ex); throw;} catch(SomeException ex){ logger.log(ex); throw ex;} 5) Accessing virtual members in a constructor Example: I.e. The following code...

40 Hyper Realistic Artworks That Are Hard to Believe Aren’t Photographs Although sometimes art is meant to stress its detachment from the reality, hyperrealism practically erases this line. Pictures and sculptures, created by hyper realist artists, will look no different from a high resolution picture, making it hard to believe this was created using such regular tools as pencils or ballpoint pens. Hyperrealistic images are typically 10 to 20 times the size of the original photographic reference source, yet retain an extremely high resolution in color, precision and detail. Many of the paintings are achieved with an airbrush, using acrylics, oils or a combination of both. [1] We have already shown you some amazing examples of hyper realistic works, but here’s a selection of the most outstanding ones. We also included some photos of the creation process just to fully convince you these are not photographs.

ASP.NET MVC 5 - A .NET Developer Primer for Single-Page Applications A majority of Microsoft .NET Framework developers have spent most of their professional lives on the server side, coding with C# or Visual Basic .NET when building Web applications. Of course, JavaScript has been used for simple things such as modal windows, validation, AJAX calls and so on. However, JavaScript (client-side code for the most part) has been leveraged as a utility language, and applications were largely driven from the server side. Lately there’s been a huge trend of Web application code migrating from the server side to the client side (browser) to meet users’ expectations for fluid and responsive UX. With this being the case, a lot of .NET developers (especially in the enterprise) are dealing with an extreme amount of anxiety about JavaScript best practices, architecture, unit testing, maintainability and the recent explosion of different kinds of JavaScript libraries.

UDOO: Android Linux Arduino in a tiny single-board computer Inversion of Control Containers and the Dependency Injection pattern In the Java community there's been a rush of lightweight containers that help to assemble components from different projects into a cohesive application. Underlying these containers is a common pattern to how they perform the wiring, a concept they refer under the very generic name of "Inversion of Control". In this article I dig into how this pattern works, under the more specific name of "Dependency Injection", and contrast it with the Service Locator alternative. One of the entertaining things about the enterprise Java world is the huge amount of activity in building alternatives to the mainstream J2EE technologies, much of it happening in open source. Underlying these containers are a number of interesting design principles, things that go beyond both these specific containers and indeed the Java platform. Components and Services The topic of wiring elements together drags me almost immediately into the knotty terminology problems that surround the terms service and component.
