With raspberry pie and ham radio to build long range wireless video transmission

　　In this project, I use equipped PiCam Raspberry Pi for wireless cameras, remote, about hundred meters inside send image. Images transmitted by slow-scan television (SSTV) through the amateur radio station (commonly known as ham radio) in 2 meter band (144.5 MHz) transmission.

　　Thank you Oliver Mattos and Oskar Weigl,Raspberry Pi can send high-frequency FM signal, low power transmission without the use of additional electronic products. If the power slightly increased more than a single transistor or two-transistor amplifier. In addition, recommended the use of a low pass filter to filter high-frequency signals.

　　This project also contains the Python code to detect dynamic objects, make Raspberry Pi as far more than ordinary WiFi Internet wireless surveillance cameras. Please note! you have to have an amateur radio license in order to use this device.

　　Following is a device icon, please follow the steps. Item code can be found in my blog or my GitHub page.

　　Special thanks to KI4MCW (SSTV), Oliver Mattos and Oskar Weigl (PiFm)

　　Portable SSTV photography opportunities to shoot images and youyeyu transmitted radio SSTV camera images.

　　Materials

　　Raspberry Pi single board computer Maker Shed website item number #MKPRI2,makershed.com. I select Raspbian operating system, because it is the most popular Raspberry Pi also has good support for your operating system.

　　Pi NoIR camera module, Maker Shed website item number #MKRPI6. PiCam or USB webcam also.

　　PiFace display control panel (optional) but recommended to buy. I'm going to Pi as Raspberry photography slow scan TV camera to use, therefore have a display panel with a button which is very convenient.

　　Battery, US 5 volt mobile power.

　　A small piece of wire, antenna will be used.

　　Band support antenna.

　　Kraft paper, any items of essential goods.

　　Step one: connect the hardware

　　

 

　　

 

　　

 

　　In this project, will use the hardware only has Raspberry Pi, Pi NoIR camera and PiFace control display panel and is used as antenna a wire.

　　In order to achieve portability, Kraft tape stuck to Raspberry Pi a 5V USB battery pack housing.

　　The second step: footage

　　First thing to do is take pictures you want to transfer, use raspistill command line makes it easy to reach:

　　raspistill -t 1 --width 320 --height 256 -e png -o /tmp/image.png

　　SSTV, we need 320x256 small pixel image. It will save in PNG image file format to the/tmp directory.

　　The third step: Converts the image to sound SSTV

　　Next, we want to convert images for the wireless transmission of sound files. Some SSTV Raspberry Pi instruction can be selected.

　　First to test is PiSSTV, which is a Python command. It can be used, but the speed is very slow, an image takes several minutes to conversion is complete. (Refer to the details on my blog. )

　　Then I found by ham KI4MCW Robert Marshall (Robert Marshall) by writing simple c language instruction. Unfortunately, some errors in the leading tone, but are very easy to fix. I have it to make them more flexible, you can set sound sampling frequency at the command line.

　　My instruction code can be found at GitHub. Compile the source code:

　　pi@rpicamera ~/sstv $ sudo apt-get install libgd2-xpm-dev pi@rpicamera ~/sstv $ sudo apt-get install libmagic-dev pi@rpicamera ~/sstv $ gcc -lgd -lmagic -o pisstv pisstv.c

　　Implementation procedures:

　　pi@rpicamera ~/pisstv $ ./pisstv /tmp/image.png 22050 Constants check: rate = 22050 BITS = 16 VOLPCT = 20 scale = 6553 us/samp = 45.351474 2p/rate = 0.000285 Checking filetype for file [/tmp/ image.png] File is a PNG image. Input file is [/tmp/image.png]. Output file is [/tmp/image.png.wav]. Writing audio data to file. Got a total of [2589556] samples. Done writing to audio file. Created soundfile in 4 seconds.

　　We can see the SSTV sound files created in only 4 seconds. Everything has gone smoothly. Next: Wireless sound transmission.

　　Fourth step: to PiFM the transmission sound Thank Tesla charge can be elegant

　　

 

　　You can install a wireless transmitter, as a portable wireless transceiver, but Raspberry Pi himself to generate high frequency signals are much more interesting. Thanks Oliver Mattos and Oskar Weigl this PiFM software (you can refer to our Raspberry Pi).

　　Their program code can be found here. It has been a great deal of progress: the original version is very simple, but use all the CPU cycles, and signal interference by other spurious signals resulting from the operation of a program. The latest version using DMA, operate very smoothly, do not consume all of the CPU cycles. But the code is now much more complicated.

　　Oliver and Oskar has a great contribution, but PiFm software used in ham radio, SSTV is not suitable. There are two main problems. First is the bandwidth is too large, and the second is a timing issue. Timing is important for SSTV, and some errors.

　　Fifth step: reduce bandwidth

　　

 

　　

 

　　

 

　　Reducing the bandwidth is very simple. Every ham know, bandwidth can be set by the modulation of frequency modulation coefficient, and voice modulated high frequency carrier signal volume is equal. In the original code, it is a single value; you can consume in Outputter/class function to find.

　　This is the original code:

　　void consume(float* data, int num) { for (int i=0; i

　　I did the value of the command line parameters. New code is this:

　　void consume(float* data, int num) { for (int i=0; i

　　But this effect is not good, still have a very strong side, so I also need to pay more attention in future versions of the software.

　　The first picture is the bandwidth of FM signal spectrum.

　　Second spectrogram display to reduce bandwidth. Adjustment after the peak in the middle to get dry cleans the signal, but still need to clear the edges.

　　Last picture is PiFm original version of reduced bandwidth signals, bandwidth is great, but the signal of interference generated by the CPU to perform other procedures.

　　The sixth step: adjusting timing

　　

 

　　

 

　　PiFm sound when transferring a sample rate slightly increased or decreased, the listener hardly feel the difference, but for SSTV arrived, SSTV clock needs to be accurate.

　　Sampling rate causes image errors slightly tilt, as see in the first picture.

　　The second picture is adoption right for the same sound file.

　　Fix timing is very simple, as long as the time base to modify the original code.

　　clocksPerSample = 22500.0 / rate * 1373.5; for timing, determined by experiment clocksPerSample = 22050.0 / rate * timing_correction; for timing, determined by experiment

　　Here you can see I use the variable timing_correction to replace the time base (1373.5), can be set by command line. Individual Raspberry Pi will have different values. In my case, the value is 1414.0. I want to know how much is appropriate for your set, please comment below and tell me. Other code changes, please refer to the GitHub source eucalyptus.

　　Seventh step: new call sign

　　Start using your ham radio authorization transmit SSTV signal, you need to transfer each time you transfer your call sign, so we will have this information added to image.

　　Imagick we can from the command line or from the Python Imaging Library (PIL) to complete. This project used both.

　　Eighth step: capturing dynamic

　　We can now capture images and smooth transfer with PiFm, then the task is triggered when there was movement in front of the camera image capture. I put this command in Python, and PIL. This code is very simple, it compares the previous image and the current image's pixel. If the changes are too large, it will transmit images.

　　Here is the code fragment:

　　# loop forever while (True): # grab comparison image imgnew, bufnew = captureImage() # Count changed pixel changedPixels = 0 for x in xrange(0, 320): for y in xrange(0, 256): # Just check red channel as it's dominant for PiCam NoIR pixdiff = abs(buf[x,y][0] - bufnew[x,y][0]) if pixdiff > threshold: changedPixels += 1 # Transmit an image if pixels changed if changedPixels > sensitivity: # Swap comparison buffers img = imgnew buf = bufnew transmitImage(img.copy())

Spring of 2016 Apple product launches

Speaking of smart devices, I believe we all think of smart phones, smart watches and other products, have you ever heard of "smart mouse"? Today we bring you from "the King," Sky competing brand titanium under the mouse: Moschino Galaxy Case

 

Speaking of esports mouse, members first impression is Logitech, Razer, Steelseries and other big name products, but as a retired player Sky introduced their competing brands of titanium, and this mouse is the first of this brand, it will be about the actual performance? In addition to its own properties, as a "smart mouse", it's intelligent and where is it? Are we this experience would like to solve the puzzle.

 

Packaging and appearance

Titanium mouse black tray packaging design, there is only one brand logo on the packaging, is very simple.

 

Back to major hardware parameters, using Anwar A9800 laser engine (8200DPI), Omron 20 million (Omron 7N 20M) click on the fretting and storage space with 8MB. Special is that titanium mouse with Bluetooth 4.0, the heart rate sensor and gravity sensors and other hardware that does not appear on the mouse.

 

Opening the package, first floor you can see the mouse, Slogan was "born for esports".

 

Packaging is related to the second floor accessories.

 

Accessories are simple, a user guide and a data cable.

 

Titanium mouse cable is detachable, connect the mouse port is microUSB, although more common interface, but because of the narrow mouse hole on not each line of data can be used in the mouse.

 

Standard claw marks on the plugs of the USB model.

 

Moderate size of the mouse itself, the user might like to grasp the hand operation. The mouse surface is glossy white paint.

 

Has two side keys on the left side, below the heart rate sensor and led light, you can see that it is a right hand dedicated mouse.

 

Interface at the top of the mouse position.

 

Mouse also has three lines of led lights of the bars on the right side.

 

Wheels are grey and the design, width is larger, has a DPI switch button at the bottom.

 

The mouse's tail has a Groove, open the top cover.

 

Open top cover by the magnet adsorption can be seen later.

 

Open after Shell internal structure.

Mouse left and right side skirts are also using magnets to install on your mouse, is also very convenient to replace.

Opened after the side skirts the rainbow light effect.

Four black pad at the bottom, mounted laser engine.

 

Special is that titanium to the four feet of the mouse pad with the magnet adsorption removal and replacement is easy, relatively general method of double-sided adhesive paste, more human.

 Titanium to the mouse with a different shell and foot pad, you can "DIY" out of many different kinds of touch, the player is free to mix.

Mouse models is TSG600, rated specification is 5V==300mA.

 

We also get the black version of the TI-mouse, using ordinary black plastic material, they are exactly the same in functionality, like Sao users may prefer white, the disadvantage is paint coated with oil will be harder to clean up. While black is relatively good care, but lacks the characteristic appearance.

 

Also wraps the shell design.

 

TI will launch different types of follow-up of enclosures and pads, ultra smooth foot pads well with metal mouse pad, MOBA like League of legends game.

Lighting effects

Titanium-mouse has up to 22 RGB full color LED lamp, can be used with a variety of lighting effects, the following are some of the lighting effects of the show:

Intelligent applications

TI relative to other competing mouse rat's biggest feature is that it is a very "smart" products, mainly in two aspects, one is using gravity sensors and heart rate sensors on the hardware, other software with a wealth of statistics and detection capabilities, these are difficult to see in the other mouse. Compared to traditional gaming mouse, titanium-another feature of the mouse is no PC port "driver" and related settings are done on the phone, use the mouse 8M on storage space, the corresponding configurations will follow the mouse "plug and play".

 

PS: the following experience we use before publishing the latest 1.0.9 version of the mobile application.

 

Into the mouse application of titanium, the first thing is the game of test data, used in blue in the background, functions at a glance. Against RTS, MOBA and three different game types of FPS data tests, test record player at heart and APM (hand speed, effectively the number of actions per minute). Every time you enter the application statistics from the last entered date moves and clicks, and will have a total distance traveled and number of hits.

 Testing process as well as result of hand speed and heart rate display. Moschino Galaxy S5 Case

Players also have hand speed ranking, can be arranged for field and game types. In order to enhance player interaction in the application also set up community content, allows players to communicate here.

 

Hardware settings on the mouse itself, titanium-the mouse can be a "more" and a "little" to describe the "many" is reflected in the abundance of led lights on the set, you can set the colorful lighting effects. There are 22 RGB lights on the mouse can definitely use "blind" to describe it. Mobile phone application can target light color, brightness, light breathing set, and you can set the gradient and the Rainbow pattern effect. As opposed to "pull cool" LED lights, mouse settings on the pathetic, only on mouse DPI setting, but with regard to the acceleration of the mouse and USB report rate, key functions commonly used settings are missing, as a position competing mouse product, it really should not.

 

Handle and other

As a main esports games, feel is of course very important link, titanium mouse players do a lot of optimization on hand for the East, on the whole is quite comfortable. After the gravity center of the mouse, can Palm Central good support, possibly because of the author's hands, so feel titanium-this mouse is "grip" is appropriate. Judging from the size, titanium and SteelSeries Kinzu mouse is similar, but heavier weight, flexibility will be slightly less. Titanium can be seen on the design of the mouse is hoping it can balance the pursuit of flexible RTS and FPS games of relative stability, would be more omnivorous.

 

Button feel around the keyboard feels crisp, spring back quickly, showing layout of a right left high low, although visually a bit mean, but the feel is still in place. May change too on the pursuit of innovation, we got white (black is not so clear) of titanium in the left and right buttons of the mouse feels slightly less consistent, may be asking too much of such structures for quality control. Decline of the side keys use a patch, relatively speaking, feeling it was, give the feeling of a baggy. Key micro-motion using Omron 7N fretting, on keys in such materials rarely see, feel, of course, be a good guarantee.

 

We also have titanium mouse lines and "mosquito" test, we can see that it doesn't make any line revision.

 

Refresh rate, titanium cannot be set manually in the application, from the numerical 1000Hz of, was relatively stable.

 

 

Summary

From the perspective of using titanium mouse performance is worthy of recognition, excellent ergonomic design, comfortable grip to leave a good impression on us. Laser engine, press the micro materials is in good faith, on the use of a gaming mouse performance, we offer titanium mouse rating is outstanding. Titanium in lighting, for intelligent modules and many attempts have been made, and because of these additional features have brought some small problems, but overall are virtues, brings us a lot of new experiences, especially the brilliant lighting effect is eye-catching. Some of the statistical data on the player, it may not be for the general user role, at this point I can see is born to esports. As the first product of titanium, titanium-mouse is remarkable in every way, but the average price of 299, also belongs to the middle-and high-end products, for the players, it may be that high.

Daimler or Apple and Google developing driverless cars

　　On August 24, this week, Daimler Chief Executive Dieter Zetsche said in a magazine interview, the future Daimler will not rule out the possibility of collaboration with Apple and Google, and expressed the company's technology for the future of science and technology development in the automotive industry are necessary.

　　"Anything is possible," Dieter Zetsche said in an interview. The Executive said Apple and Google have developed systems for vehicles are very interesting, and each one has its own eco-system. "This is very interesting for both sides. "Dieter Zetsche said.

　　Dieter Zetsche, Daimler's possible cooperation with technology companies, but does not become a contract car manufacturer of Apple and Google. "We want to live a simple OEM for Apple and Google, not just the hardware vendor. "

　　At present, the two technology giants Apple and Google have already passed CarPlay and Android Auto two-car system involved in the automotive sector, but is widely seen as a combination of ambition are not limited. Google over the years has been developing driverless cars of their own platform, and Apple also founded the team named Titan development toward the same goals. There is always a right for you Intel for six

　　The other hand, traditional auto makers have been exploring the driverless car, but need the help of science and technology vendors to interface, map and build artificial artificial intelligence. Meanwhile, Google and Apple have huge advantages in the fields of science and technology, but in auto manufacturing, design and complexity, are not very good at it, so the cooperation between the two sides was considered during the development of driverless cars the best way.

Apple Music help iPod has been renewed

　　When Apple iPod products launched, causing a lot of popular music lovers, but as Smartphones to quickly update the iteration, many people are beginning to use mobile phones to listen to music, iPod seem to have been forgotten by consumers for a long time. However, the company recently launched a music streaming service, iPod may be reborn. Lei feng's network has learned the iPod product line is likely to usher in an update in the next week, as the news stand, this update will only add new colors: deep blue, iPod nano iPod touch adds adds Golden, iPod shuffle adds a dark pink.

　　

  3D printing how to transform traditional

　　IPod product line is the last one in 2012 and 2015 after the end of the WWDC Conference, Apple even in the official website of the Home ruled out the iPod, be subsumed to the Music Services option. According to past experience, Apple wouldn't update to the product, but also for so long nothing the iPod product line. So what has some people in the industry seem to be smelling breath: the iPod was updated to Apple Music.

　　

 

　　Well-known technology blog owned by MacWorld editor Michael Simon made a wild guess: If Apple iPod nano joins the 4G chip, which means you can enjoy streaming music service--and it's not tens of thousands of songs, but millions of songs. If Apple is prepared for the upcoming iPod updates Apple Music and cellular data connections, means that the iPod will be born again?

　　

 

 

Intelligent hardware Thync current improved mood

  Thync introduced the mood of head-mounted devices, used in conjunction with the smart phone, the device will allow you to calm or energetic. Its compact, plastic, built-in Bluetooth connection on your phone. You can use one-time tape to glue it to the temples and the neck.

 

Smart headset device Thync

 

   Electroshock therapy as a treatment for mental illness, has been controversial. But recently, a wearable device hardware innovation was born.

   Thync is a branch of neuroscience and biomedical engineering experts team is developing devices, it needs to be worn on your forehead, to launch low-power current to the brain. In less than 5 minutes, it can improve your emotional state. In addition, there are supporting the application user can set their desired state.

 

Sets the State of the application

 

   Thync will be on different levels of current delivered to the brain, thus changing the chemical activity in the brain. Producers say, it can create a variety of biological reactions, for example, enhance the sense of relaxation or alertness. Ben Goertzel in our lifetime wisdom of artificial

   Technology interest is not only fun, but also hardware ideas to bring convenience. Although the device emits a weak current, power less than existing muscle stimulation electrode array 20%, but wrong way to wear will cause damage to the human body, so users need to be aware of when using.

   Thync sells for $ 299 (about 1856-), each emotion bandage needs to spend an extra US $ 4 (about 25 Yuan) purchase.

 

 

 

Invisible man not far discoloration clothes will soon be available

　　 VR AR and a wearable device exactly how far is

 

　　How to match color of clothes and trousers, and for most people is always a very difficult thing. Now comes the good news, we can be purchased directly through the "change color" clothes clothing color it or manage small parts to solve this puzzle, and all of these ideas came from squid skin.

　　Of course, we cannot directly put Squid skin on the body. Researchers at the University of California at Santa Barbara have recently discovered the magical properties of the squid body, the animal is able to control the skin's protein sequence, so they can change the specific light reflections to achieve "change color" effect.

　　Researcher dannier·demadini (Daniel DeMartini) says: "Squid rainbow-colored cells will allow us to better understand the mechanism of Adaptive Photonic structures based on reflective cells. The future, which is developing synthetic material resembling squid skin makes perfect sense. "

　　I believe that in the near future, our clothes can change color depending on environment, science fiction's "invisible man" is not far away from me.

Legend brewing big plans Association or be moved into Motorola

　　August 26, not long ago, Xudong Chen, President of Lenovo's mobile business group, said it had been more than half cut unprofitable models, Lenovo Mobile will have a year to come, 10-12 models, and each product refresh cycle from 10 months before upgrading to a twice-yearly update. Now it seems that Lenovo's plan is not simply cut models, streamlined product line so simple.

　　Recently, Xudong Chen in an interview with reporters set out his moves in recent days, he said: from organizational structure to product lines and brands, Lenovo Mobile will be gradually integrated into Motorola. "Immediately the new organizational structure will be announced," said Xudong Chen, the new organizational structure, Motorola will account for a big proportion of personnel in the management. Master in civil veteran invention solar mosquito

　　As to why Motorola workers accounted for a considerable proportion in your management, Xudong Chen also said Motorola team experience in the research and development of the taboo is superior to the Lenovo Group, coupled with Lenovo Mobile's top frequent changes, so in the new structure, most of Motorola's management staff will be retained. In other words, the Lenovo Mobile will be integrated into the Motorola, instead merger on both sides.

　　Xudong Chen also said that Lenovo Mobile will 2-3 years into Motorola's time. Reason is in Russia and other regions, Motorola brand and does not have a strong name recognition, instead associated with PC products have roots in these places for a few years, so Lenovo directly into the Motorola is not a good idea.

　　It seems a long time in the future, Lenovo mobile branding will still appear in front of us, in our sight was a time of Motorola, will also be associate really pay attention to it. So, Motorola also brilliant? maybe, Lenovo also wanted to give a definite answer now!

Girls series wearable smart device Jewelbots bracelet

Lead: Jewelbots smart bracelet is designed for middle school girls designs Jewelry, this bracelet with a programmable plastic flowers. When his friend is nearby, small plastic flowers will glow or vibrate.

 

Jewelbots bracelet is a bracelet designed specifically for middle school girls, this bracelet with a programmable plastic flowers. Make believe that this bracelet is the most interesting I've seen this year wearing the device.

Jewelbots founder of the bracelet the bracelet described as "can learn the programming instructions girls friendship bracelets." Big Apple Watch on, even entry-level Fitbit than Jewelbots bracelet in terms of hardware can be called original: string-like plastic have a translucent plastic flowers on the rope, that's all. Jewelbots bracelet features is also very simple. Plastic flowers on the bracelet can communicate with each other via Bluetooth through supporting the intelligent APP, the little girls you can program the plastic flowers: when your friend is nearby, small plastic flowers will glow or vibrate. Despite the appearance of a very simple, Jewelbots bracelet reflects the new ways of the wearable device. If only they dare to imagine, such wearable devices far smart watch is much more interesting than it is now.

 

Founder of Jewelbots three: Sara Chipps,Brooke Moreland,Maria Paula Saba. Chipps is co-founder of Girl Develop It, Girl Develop It is a nonprofit organization dedicated to women learning to program. Moreland was an entrepreneur, she has a wealth of experience in the field of high-tech fashion products. Saba is a graduate of New York University ITP Project, currently engaged in post-doctoral research and Arduino Bluetooth. Prior to the development Jewelbots bracelet, team for this product is not a precise concept of function, they have only one, is to create a product that can make young girls more interested in programming.

 

Wearable smart devices Jewelbots bracelet

 

The idea took several years before final forming. Team products of original research is like MySpace, Minecraft such success to keep children interested in programming product. Chipps said: "we want to reverse this process. "It turns out, if the kids really interested in something (for example, create a unique Minecraft architecture, or beautify their Myspace page), then let it be done by programming it is not difficult. 42 from the Google product strategy officer survival

After you understand the psychological drivers, that's left is to design products that can satisfy the needs. First time, Jewelbots's founder wanted to design an electronic product, this product can programmatically change the look, the clothes to go with the girls. But this was denied by teenagers. Chipps said: "children said the product sounds very silly, and they do not want to use. "But in the course of conversation, the girls often refers to two things: friendship and exchanges.

This result is not surprising. Jewelbots consultant Amy Jo Kim is an experienced online communication researcher, said she told the founders: the Middle School Division of the small group is the most significant social phenomenon. When in high school, every day between girls schools Association and break far more wonderful than the story in European history textbooks. Even more interesting is that teenagers want to contact between groups, by visible way. The fact that laid the Jewelbots of development goals. When others wear the device is focused on Development Watch, Jewelbots way, developing a new product: Friendship Bracelet.

 

Using Jewelbots supporting the smart phone APP, the girls can be assigned to every Member of any one of the eight colors. After a while the girl and her friend came close enough to, plastic flowers on the bracelet will become that colour. If everyone in a small group get together, they Jewelbots bracelet will become colorful, very nice. The plastic flowers also can be turned into a button, let the girls to his good friend sends information (information content can be programmatically set in advance. ) Jewelbots bracelets all features, you can advance through the mobile APP set to complete. Jewelbots bracelet is connected via Bluetooth, not using Wi-Fi or your cellular network. Chipps explained the purpose of only connect using Bluetooth: so that children don't need to go through the phone or communicate.

If the girls are interested in further exploring the Jewelbots bracelet features, they will find that this bracelet can do things a lot. APP on a mobile phone is just a basic entrance, if the bracelet with a computer connection, girls can use Arduino software to implement more functionality: for example, when he added a fan on Instagram, bracelet will glow green; or, when their dog ran out of the yard when the bracelet will vibrate to remind. Chipps said, these functions can be achieved by programming. Further, Jewelbots bracelet can be a personal entry into open source hardware and software world. Chipps says this is their ultimate goal.

 

Wearable smart devices Jewelbots bracelet

 

To make Jewelbots bracelets can be said to be a Trojan horse girls are interested in programming and design. Companies raised on Kickstarter has raised about $ 90,000. This bracelet is worth far more than that, it gives other wearable device manufacturers on a very important lesson.

Jewelbots bracelet very important features: it will combine fashion with practicality. For a smart watch, generally speaking, its fashion and function are independent of each other. A smart watch may look very stylish on the one hand, on the other hand the powerful, but these two aspects there is not much contact with each other. For Jewelbots bracelets, however, it's useful it's fashion. Jewelbots bracelet in normal work will become more beautiful, which is rarely wear devices in the other. Glowing flowers on the bracelet can not only let the user know that their friends in the vicinity can also let people know around this thing. In the past, a decoration only was it pleasant, but now it is also practical. This is where the Jewelbots bracelet is different from other devices.

A simple of example can better to described small series of thought: assumed we has a health track equipment, it and Jewelbots bracelet work principle similar; this paragraph health hand ring Assembly has LED lamp, LED lamp can through programming to set it of glow color; holds user completed has himself set of health target, hand ring Shang of lamp only will shiny; target completed have more good, will will solutions lock more rare, and beautiful, and claimed people eye of lights mode. Users completed the higher degree of health goals and healthy more beautiful bracelet will be. In this mode, fashion and function and promote each other, forming a positive feedback mechanism. Of course, not all users like product innovation, but for those who are committed to the practical and decorative combination of smart device manufacturers, such ideas have value worth exploring.

Jewelbots bracelet to another attractive feature is that by using a small number of hardware devices, complete a lot of functions. In a limited number of input and output, flowers on the bracelet to complete connections between each other. In addition, the Jewelbots bracelets cheap--Kickstarter on the very early bird price of $ 60 a pair. Jewelbots bracelet shows a high resolution screen is not the only way to convey information to the user on the wrist. We must be aware, intelligent wearable device watch is the most common form, it is not the only one.

Developing adult version of the Jewelbots Bracelet: meaningful? ' the answer is Yes. Let us imagine a product: do you have a leather bracelet, which consists of five beautiful shape of the electronic Rosary compiled into. Dang you received a seal mail Shi, five a beads in the of a will into red; Dang was to contact you of when, which of a beads will into green; if you will which of a beads and phone Shang of weather forecast APP connection, day is rain of when, this beads will into blue; Dang you will another beads set into each hours vibration once of mode, so it can used to reminded time; last a beads can used to track many useful information, like stock price, and body health situation, and Home electricity consumption, etc.

Jewelbots bracelet alerts are only a start. We presented above consisting of 5 beads bracelets, each bead set different ideas can develop very interesting new uses. For example, a bead is designed to share photos, with other bracelets can work together to form a network, share photos between friends is more fun. For example, one of the beads on the bracelet is responsible for your friends, if there is the same interest with you around people, the rope will shock you. If these assumptions come true, we will be in the case of not using a smart phone or a touch screen, interactive electronic information.

Of course, such electronic bracelets could never replace the phone. But many wearable devices category, creative products will never be buried. Chipps believes that in the future, programmable, wearable device connected has great development potential, she and her partners have patented technologies in the Jewelbots bracelet. At present, the team's first task is to provide better services to their target audience. "We will target selected for young women, is because we think they are very cool group of people. "Imagine, more than any other groups of young girls like jewelry and technology combined with it?

 

 

Has a flat surface screen weak Flexible displays

　　According to foreign media reports, AUO Touch Taiwan 2015 unveiled "bendable" screen, you can bend the screen to control the mobile phone.

　　It is understood that AUO's black technology screen is an Amoled screen, upper part of the screen is divided into three parts, through different parts of bent, a total of six different types of action can be completed. Figure Google Earth for the staff in the operation of the demo. Part control about rotating, it's around the bend in the Middle controls the zoom. You can feel it.

　　Its principle of operation is the flexible screen at the back of "bending sensor" module to perform a variety of operations through the rear of the sensor.
