Information and History of the Digital Clock

Have you ever been curious about how digital clocks work? Or would you just like to know more about digital clocks to help you make a future purchase? Let’s take a look into the world of digital clocks and learn a bit about them.

The first pocket style watch that was considered “digital” was introduced in 1883, it used what was called a jump-hour mechanism. This invention was created by Josef Pallweber which the jump-hour featured two windows in an enameled dial. Through the two windows, you can see the hours and minutes on rotating discs – the second hand had remained conventional in nature.

Next came Plato clocks, which had a similar idea to Josef Pallweber but used a different layout structure. Spring-wound pieces use a glass cylinder with a column inside, which was then attached to small digital cards with numbers printed on them  – flipping as time went on. The Plato clock was patented in 1903 and introduced in 1904 by Ansonia clock company.

D.E. Protzmann and his associates submitted the first patent for a digital alarm clock in 1956 and later patented another digital clock in 1970 which was supposed to involve a minimal amount of moving parts.

The first digital watch that included an LED display called the Pulsar, was mass-produced in 1970 by the Hamilton Watch Company. Over the many years since, many various types of digital watches, clocks, alarm clocks have been developed.

Digital clocks typically run off of an electrical power supply such as a 100-240 volt AC power cord to the wall. However, most digital clocks have battery backup in case of a power outage.  An electronic time base that ticks away at an accurate rate, and digital clocks generally handle gearing with a component called a counter. The display on a digital clock either consists of LEDs or LCD lights.

Unlike analog clocks which are based on 12 hours, digital clocks have two options. You can either use a 12-hour clock, often with an AM for morning and PM for afternoon and evening or; a 24 hour clock. Even though the clocks are useful, some digital clocks have to be changed manually when the time changes. Some of the newer model digital clocks are now able to have their time synchronized automatically by a radio signal or the internet.

Digital clocks are generally smaller and can be easier to use and read than analog clocks. Digital clocks can also be made much larger. Because of the inexpensive design and size flexibility, digital clocks are often used in cars, microwave ovens, radios, and computers.

Digital clocks help to make our lives a little bit easier – sometimes without us realizing it.  The digital clock helps in our everyday lives.


3D Projects: Which 3D Product is Right for You?

When it comes to starting a 3-D project, you can save a lot of time and money by choosing the right product from the beginning. To start with, there are quite a few free programs and programming libraries to use whether you’re creating a 3-D film, game or commercial or printing 3-D objects with a computer. It doesn’t take long to learn what you need to know about the 3-D products on the market, and you can get started right away by reading this list.


Blender is a free, open-source 3-D modeling program that allows you to create any type of virtual world you can imagine. It can be used to make still images as well as animations, and you can take advantage of the internal physics engine for game development. If you plan to create mesh models for your 3-D printer, Blender allows you to import and export files for your printing application, so you can easily edit your mesh before sending it to your printer.

You can basically think of Blender as a free alternative to professional programs like Maya and 3-D Studio Max. It has a comprehensive feature set that is expanded every time a new release is deployed. If you’re a game developer, you can import your game world and characters to the Blender viewport and use the powerful editing tools to change anything you need to edit in your file. It’s also easy to export the finished product to an external game development framework such as Unity3D or Unreal.


Unity is another free product that makes 3-D programming a lot easier. You can use it for free if you want to make games for desktop computers, but if you plan to use it for mobile games or other platforms, you’ll need to buy a license. With this visual development framework, you can actually see your game world as you develop the software code, saving a significant amount of time and easily offsetting the cost of a license. Other similar frameworks include CryEngine, Unreal and UDK.

DIY 3-D Printing Kits

You can save hundreds or possibly thousands by building your own 3-D printer from the pieces in a kit. These printers usually come with open-source software that’s compatible with programs like Blender and Z-Brush, but it’s important to read reviews about a product before spending your money. Some printers produce better results than others, and some printers are more convenient to use than others. Features to pay attention to include the type of plastic a printer uses and how difficult it is to replace the filament. Some printers can be improved with a simple modification.

As computing power becomes cheaper and software becomes more powerful, 3-D programs and printers will become more common and user-friendly. The learning curve is fairly steep when it comes to 3-D modeling and programming, but anyone can do it with a little determination. If you have an interest in sculpting or game development, take a look at some of the great products available for free.
