Flower Technologies You May Want To Know More About

จันทร์, 01/14/2019 - 00:43

For most of us, flowers are beautiful, a symbol of something we really like. It is easy to understand why people from all around the world love flowers. However, flowers are so much more than what we initially think. Those flowers that we instantly recognize are the ones that quickly attract birds and insects.

Technology is changing the way we interact with flowers, their availability and more. Nowadays, it is really easy to go online, visit a site like Flowwow, and order exactly what we like. Flowers would reach our door and we can give them to those we love. We can also keep them, of course. This is what we all see when it comes to the influence of technology on how we interact with flowers.

What we do not see is the hard work of numerous scientists that take advantage of what technology can do and transform flowers into something that was only a thought in the past. With all this in mind, here are some flower technologies you may want to know more about.

Nanoflowers That Can Improve Our Eyesight

Richard Taylor from the University of Oregon is now developing nanoflowers that are capable of helping connect electronic chips to eye nerves. This can restore the eyesight of some people that have ocular diseases. Artificial neurons use nature patterns and look just like flowers.

Flower Robots

Robotic flowers, named Florabots, were showcased at the Taipei International Flora Exposition. They were manufactured by ASUS engineers. These robotic flowers include sound and motion detectors that allow them to respond to what visitors do. Every single robotic flower can sway to music, alight and perform other actions. Science practically works with art. Visitors used RFID bracelets in order to print off special Florabot mementos.

Waterproof Materials

The leaves of lotus flowers are highly hydrophobic. This means that water droplets that fall on the leaves simply bounce off. Rises are capable of clinging to water droplets while in an upside down position, an action known as “rose petal effect”. Flower surfaces have long been studied with the purpose of creating surfaces that are non-adhesive.

Chuan-Hua Chen from the Duke University is now studying lotus leaves. He and his team figured out that the structure of the leaves can lead to the development of highly-waterproof materials.

Power Flowers

NL Architects, Dutch architectural firm, is work on Power Flowers, a design concept that aims to turn the common wind turbine into a design element, one that is actually desired by people. Regular wind turbines do not look great. In fact, most of us would not want to have them around. However, if the turbines would look like flowers, people would actually want to use them.

Flower Fuel

It is no secret that crops are now being grown in order to produce biofuel. However, one that is really interesting is mustard relative camelina. It is a yellow crop that cannot be eaten and that has extremely oily seeds. This crop might change the way we use biofuel in the future since the crop is highly scalable and even the US military is interested in using Camelina in order to develop aviation fuel.

Mbps Makes The Big Difference In The Speed

ศุกร์, 12/14/2018 - 01:12

The Internet speed has been improved in the last decade. During the early days of the Internet, it was important to have an offline version of your software so that you can work even without an Internet connection. In this modern era of cloud computing, you don’t even need to install any software to do something on your computer. All you need is a browser and a stable Internet connection.

Cloud computing is not the only area where the improvement on the Internet has thrived in the past decade. Gaming became more competitive now that there are more players playing online. Competition became bigger. Even the movies and TV shows can now be streamed without any hassle because of the improvement in the technology used.

But the Internet connection available right now is still not the best, even though it is better than a few decades ago. With data transmission having more demand than ever, the Internet speed should be able to keep up. It would not be too long when the day would come that we measure every small thing in gigabytes. Because of this, the Internet speed, or rather, the Internet bandwidth should evolve too.

The speed of the connection usually depends on the Internet bandwidth that the Internet service provider provides. Internet bandwidth is the amount of data that can be sent to the client and is usually measured in Mbps or megabits per second. When you’re subscribing to an Internet service, the higher the Mbps would give you a better-perceived speed. And that’s because of the bandwidth.

Think of the bandwidth as a freeway; the more lanes you have, the less congested the traffic would be. For example, if 1 Mbps is one freeway and you’re downloading a 10mb via a car, the car needs to cross the freeway ten times for ten seconds. But if you have a 5 Mbps freeway, it would mean four more additional freeways. Now that we have five freeways, we can also run five cars. Running five cars means that we can transport that 10mb in just 2 seconds. That’s the reason why a bigger Mbps will be faster.

A lot of Internet service providers are offering their services in 5 Mbps standard. There are people who are ok with that, especially with light browsing. However, the Optimum Internet speed for gamers and people who use cloud computing for apps is higher than that.

Apps, like the Google Docs, would require a fast Internet connection so that people can collaborate on projects in a real-time environment. Gamers will also want to get a faster Internet because of a certain thing that they hate the most when gaming: lag. Streaming would buffer if the bandwidth is not that good. With a faster Internet, more things can be done and more time would be saved. But when to know if a bigger bandwidth is overkill?

20 Mbps is for people who want to get their casual streaming, occasional music downloads, and loading photos fixed. 100 Mbps is for people who want to get a decent speed even when sharing with a lot of people, like family usage. 200 Mbps is for the people who want a fast connection even though a lot of people uses the internet to watch HD videos and play multiplayer games. 300 Mbps is already too overkill for people who want this in their homes. This bandwidth is for people who run computer shops. If you need 400 Mbps, chances are you’re using it for an organization, like a building that houses a lot of employees who uses a lot of data to keep things running.

The more bandwidth you order, the more expensive your bills would be. The key to making sure that you pay the right amount for the service you’re acquiring is to know what kind of activities you do online. If you’re a casual browser and just like to read articles or scroll down your news feed, a lower bandwidth is good. But if you’re one of those who want to have a fast Internet, then paying extra for an extra bandwidth would be the best solution for you.

What Will Smartphones Look Like in 10 Years?

จันทร์, 12/03/2018 - 00:34

The smartphones of these present times can be regarded to be emblematical technological oak trees that could not have been even imagined two decades ago. With every innovation in high-speed connectivity, sensor technology, advanced touchscreen interface and powerful cameras among many other features, there are no boundaries to what smartphones can do.

However, given the far that technology has come within a handful of years, it is worth considering just how far on that man`s innovative mind will shape the smartphones of the future. Let’s dive into some of the features that the smartphones of 2028 will be endowed with.

1. NextGen Phones Won`t Need Chargers

At one point in time, we have all complained about our mobile phone`s battery life. As a result of this, over the years, manufacturers have put a lot of effort into enhancing phone batteries with every new model. However, despite making such advancements, they also come up with faster processors which end up draining more energy.

A decade from now, this problem is likely to be a thing of the past due to the potential breakthroughs in power generation for smartphones. Future new releases will be powered by nano-batteries, hydrogen fuel cells, kinetic energy or even solar power. With technology such as kinetic energy harvesters being in place, you’ll find that next gen phones will be charging as you move about!

2. New Cell Phone Tech Will Enable Smart Phones to Recognize Their Owners

Over the past recent years, myriads of smartphone manufacturers have been in the business of trying to innovate methods of reinforcing smartphone security while concurrently providing a means by which users can avoid irritating PINs. Presently, most smartphones have features such as fingerprint and iris scanners which have already been proven to be vulnerable to hacking. These shortcomings are however expected to be alleviated with the upcoming phone deals.

New cell phone tech such as advanced facial recognition which scans facial features as well as examining a person`s head and face contours are set to be the future of Android. In addition to this, the recognition software will be made even more difficult to hack as they will be wired to recognize a person`s other unique attributes such as your voice and typing patterns.

3. Augmented Reality Will Become Common

The next-gen phones are bound to augment reality to the point of even bringing about tremendous changes in industries such as online shopping. Picture buying a dress or shirt online and when you view it on your phone, you get to see how it would exactly look on you. In addition to this, the iPhone future could be all about revolutionizing pivotal industries such as healthcare and retail by taking augmented reality a step higher than it already is in.

What`s more is that with the progress of app developers being given access to mobile phone augmented reality toolkits, the future of Android and the upcoming windows phone could be centered on taking communication to a whole new level. This is because app developers will already have the power of accessing phone motion sensors as well as their cameras hence enabling them to come up with apps that can lay digital substances on the phone camera’s live view and still maintain accuracy when moved around.

In ten years’ time, this technology will have advanced to the extent that smartphone will not only have the ability to capture and alter images; they will also have the power of projecting them to the real world. This means that on top of the expected foldable screens from next-gen phones, it is highly likely that communication with smartphones will entail talking via the use of holograms.


As we have seen above, the possibilities of what our smartphones will look like in the future are endless. As much as it is impossible to predict the precise details of what will take place in the future, one thing that you should rest assured about is that your phone will not be similar to the one you will own in the year 2028.

Do you have any thoughts or ideas that you think people should expect from future phones? Please feel free to let us know some of them. Your comments will be highly appreciated!

How PCBs are made – the basics

พฤ, 10/18/2018 - 04:11

The PCB manufacturing is important step towards successful build of electronic equipment. The quality of device, smooth operation may be influenced by printed circuit board – if it is well built, device works as planned, and if it has flaws then it may bring some deviations from normal operation. Anyway there are billions of electronic devices around the globe and all of them use PCBs as basis for circuits. Earlier devices were larger, used lots of through-hole components, but today in modern world electronics is very miniature and dense, thus PCBs become much more complex requiring more and thinner tracks, more layers and should work on high frequencies. So not only PCB designer has tough task, but also a PCB manufacturer should be able to follow the trends.

But despite the requirement change, the whole process of PCB manufacturing remain practically the same.

PCB materials

General purpose PCBs are manufactured using widely known FR4 board material also known as glass-reinforced epoxy laminate material. FR4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant.  FR4 material is commonly used and of its low cost. IT is manageable to work up to 1GHz frequencies. If you step to higher frequencies, then you may need PTFE material which can be used for up to 10GHz electronics. The main downside is that it is expensive as it is harder to process the boards.

The manufacturing of PCBs

The manufacturing of PCBs normally is based on chemical etching of unwanted copper leaving only tracks on board. Common etchant is ferric chloride. There are also other etchants used depending on manufacturer and technology.

The track pattern on PCB is applied by using photographic process. During this process the copper on bare PCB is covered with thin layer of photo resist. Then it is exposed to light through photographic film containing track image – this way tracks are passed on to photoresist. In following step tracks are developed in special solution where exposed to light photo resist is etched.

The next stage involves etching of copper. The copper covered with photo resist isn’t affected by etchant. This way all unwanted copper is removed leaving only required tracks. Etching process require knowing the concentration of ferric chloride, the temperature and etching time.

Other methods involve different techniques such as milling. Accurate computer guided milling machines remove unwanted copper. Milling takes long time and is suitable only for prototyping or manufacturing of small quantities of PCBs.

Multilayer PCBs

Today even less complex electronic devices use more than two layered PCBs. The reason is same – increasing amount of surface mounted parts and EMI compliance. It is more convenient to trace signal, power lines in different layers leaving more room for components and designers imagination.

Multilayer PCBs are made similarly as single layer, just material is much thinner. Thinner individual boards are then glued together that are interconnected with vias. Manufacturing of multilayer PCBs require accuracy when matching individual boards together. There can be many problems when heat gluing boards together. They can warp. So designing of these boards require some knowledge.

Drilling holes and placing vias

Almost all PCBs have some number of holes and vias. Holes normally are used to mount larger components, fix the board to enclosure or be used as vents. Vias are so called plated holes the carry connection from one side to another or between layers. Drilling is done automatically with drilling machine which reads CAD file with hole size and position information. The price of board may depend on amount of holes and vias, so if possible use less of them.

Plating and solder resist

After holes are drilled, the next operation is plating and applying solder resist layer. Plating ensures better component soldering and connectivity. This process also is known as tinning. The cheaper methods use solder to cover exposed pads, for better results there may be gold used. Solder resist in other hand isolates other areas from solder adhesion. It prevents from solder bridging, and also serves as protective layer. You can choose different colors of solder resist for instance the most common is green.

Silk screen

The last but not less important layer of PCB is silk screen. It carries all information to the board. Here can be marked positions of different components and their values, company logo, board identification, warnings and version. There are several silk-screening methods available:

  • Silk screen-printing can be utilized when the registration tolerance is 5 mil.
  • LPI (Liquid Photo Imaging) provides more accuracy when line widths are greater than 4mil.
  • DLP (Direct Legend Printing) is the most accurate and has the highest cost for consumables.
Optional steps

After PCBs are manufactured they are cut or routed in to individual boards. Also the may be tested for connectivity. If you are planning large production of devices, is advised to build a prototype to test the layout before running all batch of PCBs. This step takes time, but can save tons of money. You never know if you need small adjustment to make, replace some parts or do other minor adjustments.

DIY: Using Drones to Sell Your Home

พฤ, 10/18/2018 - 01:24

The technology used in real estate follows the same patterns you would see in any other field. The tools used in the field advance and evolve in order to provide new and exciting opportunities. Drones have become the newest up and coming development that have changed the way we approach photography and videography. In an industry that thrives on online presentation and marketing, the more advanced the photography techniques the better. Real estate businesses that invest in drones are seeing a large payoff when they are able to present homes in a manner that provides their customers with incredibly detailed views of a home. Professional real estate companies are able to use drone services as a selling point for their services due to how important their use has become to the business.

How Drones are Used

Drones have become so intertwined with the real estate industry that many believe the tool to be invaluable to their work. The reason why is obvious: flying cameras have revolutionized the industry, overcoming feats that would have been unimaginable a few years prior. Like taking sweeping shots of an estate from hundreds of feet in the air in minutes when it used to take days. The machines are so accurate and easy to control that shots are capable of being taken from as high as hundreds of feet up to as low as a couple inches off of the ground.

Glidecams are the ground-based versions of flying drones and can transition videos to the inside of a home. It has become easier than ever to fully render a home online for buyers to virtually explore. The cameras that can be attached to the flying platforms may be built in or added on, but their quality is commonly above average, Real estate businesses usually spring for the HD camera models which means clear, vibrant pictures of properties. Dramatic shooting is done in a way that adds to a home’s appeal and can takes full advantage of the advanced technology installed into the drone.

Advancing Drone Technology

The original drones, like most technology just starting development, was unwieldy and expensive. The military technology was only available at high prices, while also lacking the durability and utility of modern drones. Newer manufacturing techniques have allowed for dramatic shots in a clarity that would have cost a fortune compared to the prices you can snap them for now. The software has become so advanced and adaptable that you could fly your drone into a home and have it continue taking pictures inside without any danger to the house or to itself.

The drones you can buy online today are often completely customizable too, meaning that the rig can have any number of attachments. Your drone is as expensive as you want it to be, an invaluable part of any DIY project. Once the drone is set up and taking photos, the next step is using these photographs to sell your home. Listings with more photos attract more attention, they feel more honest and provide an in-depth view into any property.
