How Einstein and Newton Help You Out

Posted in Technology, Theory on June 26th, 2011 by admin – Be the first to comment

The laws of Physics explain all that goes on around you in the most simple (or as we figure out in college, intensely complicated) method. The laws of Physics are your sharpest tools to build a successful Rube Goldberg Machine. The two that you will need the most are Gravity and Momentum. They will often go hand-in-hand to work against each other, to make your machine carry the connecting elements, or as I call them, the ‘Travelers’, across the machine and towards the final goal. Remember these basic rules:
•Gravity will pull the traveler down, it will build ‘Momentum’, and will then work against ‘Gravity’ itself to climb up. Use this to knock through a barrier or initiate a new traveler, or to help the traveler climb up towards the next part of the machine.
•It may be useful to know that
◦Momentum = Mass × Velocity
◦Potential Energy = Mass × Height of the traveler above the base level × Acceleration due to gravity
◦Kinetic Energy = (Mass × Velocity2 ) ÷ 2.
Use these and a few trial runs to perfect each part and make a Rube Goldberg Machine.

Dissecting a Rube Goldberg Machine

If you will examine each moving mechanism of a Rube Goldberg Machine, you will notice that there are three vital ones – the pulley, the dominoes, and a ball as a traveler. Using the proper counter-weight, the pulley is excellent for pulling your traveler up or gently letting it slide down. For example, a traveler will land in a cup, act as the counter-weight, and pull the new traveler, which is kept in the other cup, upwards. The cup may be positioned such that on reaching the top floor, the cup will tilt and slide the traveler onwards. Dominoes will always be found in a Rube Goldberg Machine. They are difficult to put up, but highly rewarding to be brought down with accuracy. Face it, it’s just fun to watch a length of dominoes collapsing and cascading! Dominoes may be curled around the machine. You can also use pivots or levers so that the last domino that falls from one stack will hit the lever, which will rotate around a pivot and knock down the second stack. The ball is the most widely used traveler you will see, and for very logical reasons. It’s round, moves fast enough to provide good momentum, can move around inside tracks or grooves, and all that. So whenever in doubt, throw a ball in the thing.

Before carrying out any of the steps mentioned below, understand the real meaning of restore. When you restore an iPod Touch, all the data stored on the iPod Touch will be erased, including music, videos, calendar information and personalized settings like themes and passwords. The device is formatted and the original factory settings are present on the iPod Touch. Unless you have created a backup of your data using the iTunes sync feature, all the data present is lost during restoration. It is best to keep an up-to-date backup of your data, using the sync feature. Read all the steps first, before performing any.

How to Restore an iPod Touch to Factory Settings
•Before restoring, check that the iTunes software is installed and running on your computer, and that the most recent version is present.
•Connect the iPod Touch to your computer, using the provided USB cable.
•In the iTunes software, look for Devices on the sidebar and under that pane, your iPod Touch should appear. Select it.
•Select the Summary tab.
•Select the Restore option.
•You will receive a prompt to back up your settings before restoring. If you have not recently created a backup, click on the Back Up button. If you have a backup of your data, click on the Don’t Back Up button.
•Select the Restore button in the next prompt.
•Do not touch or click anything on the screen or the iPod Touch, until the restore process is over.
•Once the process is over, a prompt appears, the iPod Touch restarts and shows the Apple logo.
•The iPod Touch has been successfully restored to factory settings.
How to Restore an iPod Touch from Backup

DVD Information Products

DVDs are an excellent choice for the delivery of an information product. And despite what many people seem to think, DVDs are not difficult to create, don’t require investing in expensive software, and don’t come with the requisite hassle of carrying inventory, manufacturing, and shipping. Those are just convenient excuses for marketers who won’t put forth a little effort to discover the truth.

Expensive software is definitely not required and DVDs are surprisingly simple to create. As a matter of fact, you can create a DVD information product and not spend a dime. You can use several “free ware” programs which are software programs anyone can use for free. And the software I used to convert video files into DVD files even has an excellent support forum to answer your questions. The service provided is better than I’ve gotten with products I bought in the past. As for manufacturing & shipping, there are several options. The one I use (Kunaki) will create & ship the DVD on demand at their facilities and pass the costs on to the customer. They charge less than $2 for the physical DVD (including DVD cover) and a nominal $3 handling charge. And first class shipping via the US Postal Service to most US locations is less than $2 as well. Customers have the option of paying more for speedier delivery if they so choose. All you have to do is upload the files to the publisher and drive traffic to your order page. It couldn’t be much simpler.

Several aspects of DVDs should be appealing to information publishers. First, DVDs have a higher perceived value than an online video course or a book. How much will you pay for a book? You can march into almost any bookstore in America and buy a book on any topic for less than $20. Good luck selling your book for more than that. DVDs on the other hand are often sold for over $100!and remember it costs less than $2 for the physical DVD (including DVD cover). The rest of it goes straight into your bank account. And since you’re self-publishing you don’t have to share the profits with a middleman. read more »

VHS VCR Combinations

Posted in Theory on September 25th, 2010 by admin – Be the first to comment

The first thing that you will need to do is get a DVD recorder that enables you to convert old camcorder files. There are many reviews of such VHS to DVD recorders that you can read online. Once you know for sure that a certain DVD recorder will let you convert VHS files you must obtain one for yourself. There are plenty of such VHS to DVD converters available in the market.

Now you need a working VHS source machine, because this is the only way for you to read the VHS files. Any old camcorder or a VHS player will do. You must now proceed to connect the VHS source to the DVD camcorder before you go any further and record VHS to DVD. Now you need to start the recording of the DVD on the recorder (after inserting a blank DVD of course), and then start playing the VHS tape as well. The content will then get recorded in the DVD format. You must consult the instruction manual of the DVD recorder before you go ahead and start this process.

Some of the best DVD recorders that are available in the market today for recording VHS to DVD are as follows.
•Panasonic DMR-EZ48VK DVD Recorder/VCR Combo with HDMI
•Samsung DV-VR375 DVD Recorder – VCR Combination
•Toshiba DVR620 DVD Recorder VCR Combination
•JVC DR-MV150B DVD Recorder/VCR Combination
•LG RC897T DVD Recorder/VCR Combination
These are some of the best high speed VHS to DVD recorders available today, and they should be able to sufficiently satisfy all your conversion needs. Ensure that you are using the right kind of DVD’s and that there is no date already on them beforehand. Synchronizing the DVD recorder with the VHS source is also important as this ensures that none of the data on the VHS file is lost in the process. This method also ensures that VHS to DVD recorder copy protection is overlooked. What this means is that even VHS files that are copyright protected are converted into the DVD format for your benefit. These articles on how to copy VHS to DVD and how to transfer VHS to DVD will also help you learn more. read more »
