Find out what the warning signs of a failing GPU is, which card should you upgrade to if observe these indicators and whether you are able to upgrade the GPU of your laptop.
1.The Most Popular Games Are Getting unplayable
One of the most obvious indicators that you are in need of the GPU upgrade is when your computer is struggling to run the latest games. It is possible to notice this in the event that you bought your graphics card over three years back.
If you find that your computer has issues when you play most recent Triple-A games, it may be time for you to update your graphic card, or at the very least change the game’s settings to a lower graphic preset.
If, even with a lower setting your computer struggles to play the games you want to play This could indicate the graphics card has almost gone and it’s the time to replace your graphics card for those who want to carry playing the latest games.
2.Your Graphics Card is Infected With Dying
You might not even be aware you have a graphics card that is likely to fail. There are many ways that the GPU is prone to failure the most obvious is when your computer begins to crash often when playing games or loading.
Another indicator of an indication of GPU issue is that your display could be shaky or display artifacts when playing games as well as playing YouTube videos.
These issues could be caused by a variety of possibilities, such as an GPU malfunction, overheating the chip, dying GPU core poor VRAM, or a bad or corrupt GPU overclock.
If your computer has a low GPU overclock, you’ll have the option of resetting the overclocking settings , and then start over. If your computer is overheating then it’s time to cleanse your PC and eliminate the buildup of dust. In other words, the only way to fix it is to upgrade your GPU.

3.A bottlenecking GPU
GPU bottlenecks are when your GPU is limiting your CPU and in a significant way. Every PC has bottlenecks however, they are a problem when they’re affecting the performance of your PC and require to be addressed.
If you connect an ineffective GPU with a fast CPU this will create an issue with the CPU which means that your computer will not perform as it should. In the same way, if your GPU is weakening in time, it will begin to cause problems that are not fixable which means that your GPU will require an upgrade.
4.The frequent blue screens of death
You may have encountered an “blue display of death” error, since they’re quite frequent.
Did you know that there could be a myriad of causes to the errors? A defective memory module or a damaged hard drive, as well as a variety of other components of a PC can trigger the blue screen– which includes a failing graphics card.
To determine if you are experiencing a problem you are running a GPU-intensive game and observe whether your computer displays an error message that reads “Blue Screen of Death”. If so, then you are able to pinpoint the issue. When your computer is crashing it will display an error message in the BSOD screen. Be sure to write the error message so that you could use it to determine the problem with your system.
Prepare to dig into your pockets as you’re about purchase the latest graphics card!

5.It is not possible to play games with High Resolutions
It’s not all about a poor GPU. If you’re playing the most recent Triple-A games but aren’t able to play them at the maximum settings, it’s the right time to change your graphics card to higher-powered one. This will keep the excitement burning.
How do I upgrade my laptop’s Graphics Card or GPU?
It is nearly impossible to upgrade laptops’ graphics card however, there are some exceptional examples, like the Dell Precision M6700. Watch the video below for a step-by-step guide to upgrade your laptop’s GPU and improve gaming performance.
Another option is to use the external graphic processing unit or eGPU.
A eGPU is a different piece of hardware that you can utilize to boost your laptop’s graphics , so it is able to play more demanding games than it’s currently capable of.
But keep in mind that there are some laptops that are not compatible with eGPUs. Some might need that your eGPU is from the same manufacturer that your laptop is from.
Before you upgrade your graphics Card
Here are a few points you should think about prior to upgrading your GPU.
Be Sure that your GPU has enough power
If you’re planning to upgrade to a graphics processor, be sure it lasts you for at least some years before having to upgrade your graphics card again. This is why you should try to purchase the most powerful GPU that’s available on the market.
Do not choose old models, when you can. If you’re considering the second-hand GPU Try to find out what the previous owner had been using the device prior to buying. Did they use the GPU to play games is it part of an mining system for cryptocurrency?
Check to see if it fits in your Case
Since GPUs are getting larger and more powerful, you should be sure that the GPU you’re thinking of buying fits into the case you have, and the other components you have. It’s not an issue even if it isn’t as you’ll be able to return the item, but it’s good to verify that it’s a good fit before you purchase.
Verify the Power Supply Rating
Since your GPU is among the most demanding components of your system, ensure that your power supply is able to provide a GPU upgrade before you buy one.
If not then you’ll need change your power source along with. A power supply typically costs less than the graphics card, which means there’s no reason to fret about price.

NVIDIA and. AMD: Which to Choose?
If you’re not constrained in terms of budget, NVIDIA is the way to take. NVIDIA Graphics cards nearly always at the top of the list in all performance studies.
If you’re on the funds to purchase the latest NVIDIA GPUs, you could opt for AMD instead. AMD’s GPUs may not be equipped with the most efficient and fastest efficient performance in terms of graphics however they offer incredible value for the amount you’ll have to spend for their services.
Is it time to upgrade Your Graphics Card?
We hope that you didn’t spot any indications that your GPU is in need of an upgrade but if it was the following guide will assist you make an educated choice.
While it’s impossible to upgrade the GPU of your laptop There are some methods you can employ to boost the gaming performance of your laptop.

District Hotspot Quick Tips
Our school district has a limited number of T-Mobile and Verizon Wi-Fii hotspots available for families without home internet access to borrow. These devices provide Internet access using cell phone towers, just like a cell phone does. Hotspots do not supplement or strengthen existing home network performance, and they are dependent upon having a reasonably strong cell signal to function properly.
Turning a Hotspot On or Off:
- When you first plug in the hotspot, it is in battery charging mode.
- To turn the hotspot on, press and hold the small power button on the front until you see the word "Welcome" appear on the screen on top.
- To turn it off, press and hold the power button until you see "Goodbye" on the screen.
Connecting to the Network:
- The hotspot box will have a sticker with its network name (SSID) and password. This information can usually be found inside the battery cover of the hotspot, if the box is not available.
- Follow the appropriate steps for your device to connect to the hotspot’s SSID/network name.


The use of hydrogen as a tracer gas has also generated much interest due to helium supply issues. Two hydrogen sensor technologies are currently in use in production leak testing applications. The first is the same magnetic sector mass spectrometer technology that is used in helium leak detectors. In most commercially available helium mass spectrometer leak detectors the option is available to tune the mass spectrometer to detect hydrogen. The second detector that has gained some popularity is a chemical sensor that is specific to hydrogen gas and is typically mounted on the end of a handheld probe for sniffing applications.
Why Consider Hydrogen?
In considering alternate tracer gases let’s revisit the following list of characteristics to consider in selecting a tracer gas for leak testing:
- Natural Ambient Concentration
- Environmental Concerns
- Atomic Mass
- Gas Viscosity
- Detectability (sensors or instruments available, and detection limits)
- Suitability of Sensor (rugged for production environments)
- Applicable Test Methods (influenced by sensors)
Both low cost and availability make hydrogen a qualified tracer gas candidate. Because of safety issues, those using hydrogen as a tracer gas are using a mixture of 5% hydrogen in 95% nitrogen, called Forming Gas. This mixture is considered safe and non-flammable. However, this creates a dilemma when comparing using forming gas to other tracer gases in 100% concentration. Simply stated, when using this diluted gas mixture the concentration of gas escaping the leak will be only 5% of what it would be if the concentration was 100%. Thus, the reject limit for the specific application would be reduced by the same amount. For example, a reject limit of 1 x 10-5 atmcc/sec for 100% tracer gas would be 5 x 10-7 atmcc/sec for the same gas at 5% concentration.
Hydrogen gas has both a lower atomic mass and gas viscosity compared to helium giving it a slight advantage over helium. Hydrogen also has a lower natural concentration (0.5 ppm) in ambient air compared to helium (5 ppm). However, there are many sources of hydrogen that need to be considered that would increase the natural hydrogen concentration and have a significant impact on the sensitivity of an instrument. This can be a challenging problem in a mass spectrometer leak detector where background levels of hydrogen emitting from hot metals and residual water vapor can cause background levels in the mass spectrometer to be as much as 100,000 times higher compared to helium. This, perhaps, is the single biggest factor that limits the use of a mass spectrometer as a sensor in hydrogen applications.
Finally, the design of the sensors and how the sensors can be implemented into a production leak testing application have a significant impact on how hydrogen can be used as a tracer gas.
Test methods using Hydrogen
Manual sniffing is the most common method where hydrogen has been recently implemented as a tracer gas. Inficon’s Sensistor leak detector claims a leak rate sensitivity of 1 x 10-7 atmcc/sec with 5% hydrogen tracer gas. This is close to the sensitivity of what is claimed for a helium mass spectrometer leak detector in sniffing mode. Real life use, however, shows that a more practical leak rate limit for this instrument is closer to 1 x 10-5 atmcc/sec.
Helium mass spectrometer leak detectors tuned to hydrogen can also be used in sniffing applications. However, they suffer from the hydrogen background limitations described above. These hydrogen background levels may vary significantly over a range of different manufacturers making it difficult to state the true sensitivity in sniffing mode.
The chamber accumulation method is one way to perform more automated and global testing with hydrogen. In this method a sniffer probe is used to monitor rising concentrations of the leaking tracer gas that is collected in a surrounding chamber. Proper integration of the hydrogen sensor or sniffer is critical to the success of this method. Nevertheless, the accumulation method suffers from lack of sensitivity, particularly for larger test objects and when fast cycle times are required. Typical sensitivities are usually no better than 1 x 10-3 or 1 x 10-4 atmcc/sec. Hydrogen accumulation is fairly close in leak rate sensitivity compared to helium accumulation. However, when compared to the more common helium hard vacuum technique, the accumulation method is much less sensitive, less repeatable, and always requires longer test times.
The traditional helium hard vacuum method can also be adapted to hydrogen tracer gas for a typical helium mass spectrometer leak detector equipped with the option. However, as mentioned above, in traditional mass spectrometers the hydrogen background can be very high. For this reason it is uncommon to implement hydrogen tracer gas leak testing in the hard vacuum chamber mode. Typical sensitivities are no better than 1 x 10-5 atmcc/sec.
While hydrogen appears to have some of the ideal properties of a tracer gas, particularly compared to other alternate choices such as argon, there are significant challenges when implementing hydrogen. The use of hydrogen has seen modest success in sniffing applications, but due to sensor and hydrogen background issues, it is not an equivalent replacement for helium in the chamber test methods that are commonly used in production applications.

SAE AS-4C, also known to the robotics community as JAUS (Joint Architecture for Unmanned Systems) version 4 has been out for a few years now and is making inroads in the robotics community. Essentially it is a set of standards that define how components of robotic systems talk to each other. One of the goals and why the DoD is pushing it is to increase the likelihood that many separate entities can contribute working components and improve the capabilities of existing systems.
The standard beganin the government some years ago but has moved to the Society of Automotive Engineers. One of the big changes since moving to SAE is the use of XML files to capture aspects of the standards so that they are explicitly defined and to allow automated code generation tools to build and test the software that implements them. One such tool is the Jaus Tool Set. Read More
Most c++ developers who work with GNU/Linux are familiar with Make for building applications. I first created my own make files while using avr-gcc and for simple projects that don’t have lots of files or subprojects this is fine. But as a project grows or you want to split a large project into sub-projects, Make be difficult to work with on its own. A crop of tools such as Autotools, CMake, and QMake are out there just to make the creation of Makefiles easier. SCons goes a different route of pulling away from make and using Python as it’s backbone.
When I get a new development board I like to make sure I can set up the development environment on my laptop which includes GCC and the rest of the toolchain for cross-compiling. Cross compiling in this case is compiling a C or C++ program on your pc or laptop that will run on another architecture such as AVR (Arduino) or BeagleBone (Arm). The method we’ll use for this will generate both the tool chain and all the software that runs on the board. You can always download the pre-built images, but this will build them from scratch to give us more flexibility to customize the system. This post will show you how to build this image and load it on to the BeagleBone. Using gcc to build C++ programs will follow. Read More

The BeagleBone has a row of four LEDs next to the ethernet connector that can be controlled easily. On a board like the Arduino, you’re writing to a memory location mapped to an output pin. For devices like the BeagleBone that run linux, it’s more like writing to a virtual file and letting the kernel do the rest. What’s nice about this setup is that any programming language that can write to files can control your LEDS
Since the BeagleBone comes with Python, controlling the LEDs with a Python script is the easiest way to demo the LEDs without the need to compile or cross-compile. Read More

The BeagleBone is the latest offering from the BeagleBoard people offering a similar architecture (less the DVI and USB hub). They cut the size down and changed the form factor similar to the Arduino (and an Altoid box) to offer stacking shields, or “capes” as they wish to call them. The storage is contained in a tiny MicroSD card which makes programming easier than flashing NAND and bricking the board while you find a JTAG less likely.

TWO LEVEL DECOMPOSITION
The discrete wavelet transform is a hierarchical subband technique where the subbands are logarithmically spaced in frequency and represent an octave-band decomposition. To start the decomposition, the image is filtered in both the horizontal and vertical directions using separable filters. This creates four subbands as follows:
Subband LL1 represents the horizontal and vertical low frequency components of the image
Subband HH1 represents the horizontal and vertical high frequency components of the image
Subband LH1 represents the horizontal low and vertical high frequency components
Subband HL1 represents the horizontal high and vertical low frequency components
To obtain the next level in the decomposition the two filters are again applied, but only to the LL1 subband. Again we obtain four subbands labeled LL2, HH2, LH2, and HL2 with representations similar to the first level subbands.
The following example illustrates the discrete wavelet transform using 9 tap symmetrical quadrature mirror filters. Some of the subbands have been amplified to show the details.

What’s the Difference Between Hardware Keylogger and Keylogger Software
Do you know the differences between hardware keylogger and keylogger software? In short, keylogger, which is categorized into two main categories: software based keylogger and hardware-based keylogger, can silently record every keystroke typed on a computer without any notice of the computer user. All keyboard activities can be captured in stealth mode. Keystroke logging is useful for parental control, employee monitoring or any legal personal use. This article not only analyzes the detailed differences between hardware keylogger and keylogger software, but also tells you how to choose an appropriate keylogger.
The Differences between Hardware Keylogger and Keylogger Software
We can take a look at the differences from the definitions and functions of hardware keylogger and keylogger software. After that, you will understand which keylogger suits you better.
Software-based keylogger is normally installed on your hard drive, which is called spy software. Software keylogger is wildly for such circumstances. Parents can install a software keylogger to monitor children’s Internet activities. Employers install employee monitoring keylogger on company computers to keep a tab on employees’ online working activities. Software keylogger can send logs to a predefined email or upload to FTP which makes it convenient for people to check the monitoring logs. Some parental control keylogger software even includes websites and applications blocking features, and employers can spy on staffs’ desktop with employee monitoring keylogger in real time.
Keylogger software is smart, powerful, and invisible. But the problem is that some software-based keyloggers can be detected and removed by anti-spyware.
To bypass the check of spyware removal tools, people resort to Hardware keylogger. Hardware keylogger is made up of a tiny memory chip embedded in a device that is applied via the computer’s bios or else through a physical device plugged between your keyboard and the computer. Keystroke information is stored in a tiny memory chip in the hardware keylogger that can be browsed by using special programs that usually come with the hardware keylogger package.
Detection of hardware keylogger by using anti-spyware is impossible. So it becomes difficult for outsiders to notice the existence of hardware keylogger if they don’t have the knowledge of what hardware keylogger is, where it is normally installed, and how it looks like.
True stealthy, but the function of hardware keylogger is limited and unitary.
EaseMon Keylogger Software
It can be concluded from the comparison above that software-based keylogger seems more powerful yet may be easy to be detected and deleted. However, EaseMon keylogger software is hard to be detected by the target Mac users and provides the most professional and secure monitoring features. The key features of EasesMon keylogger software are listed in the below.
- Record composed emails
- Log typed messages, accounts, and passwords
- Log both sides of messages in Skype, AIM, Adium and iMessage
- Record websites visited in Safari/Chrome/FireFox
- Track websites visited in Private browsing mode or Incognito Mode
- Calculate how long an Application has been used
- Correlate application logs with captured screenshots
- App report by the user to detect who are wasting work time
- Take a screenshot when a keyword is triggered
- Play the captured screenshots as a slideshow
- Multiple notifications based on Alert categories
- Send out notification emails periodically
- View logs online anywhere
- Export/Print logs as archive or evidence
- Remotely update or uninstall EaseMon Client
- Remotely Log Out, Restart, Shut Down the target Mac
- Stay invisible and undetectable
- Monitor both Local and Network Users
Software or Hardware Keylogger for Mac Spy?
Applying a Mac spy program is one of the most common ways to key log a Mac. Apart from logging keystrokes, recording websites, some Mac spy software will also do screen capturing every several minutes.
Hard Parts about Running Mac Spy Software
The difficult parts about running Mac spy software are as follows.
- Users access control of Mac
- Obtaining reports
The first one is doable if you are the admin of the target Mac. Some spy software for Mac even do not require admin password or admin privilege for installation or running.
For obtaining reports, generally this involves returning to the computer and then pressing an odd key combination or something and you’re presented with a simple login window. After the password, you’re granted the control panel for settings and reports.
Some Mac spy software will allow you a one-time setup of reporting paths. For example, reports might be sent online every xx minutes/hours to an online destination of your choice via email or FTP. This way, you don’t have to return to the computer and you can read the reports from your office or elsewhere.
Limitations of Hardware Keyloggers
Another option is hardware keyloggers. These are tiny devices that look like simple adapter plugs that go between the keyboard and the computer. They don’t typically capture screenshots or do fancy online reporting, but they are undetectable and they don’t have problems with user access control. The downside is that they are visible and easily unplugged if they are found.
Getting the info off the keylogger device involves returning to the computer at some point and take back the hardware spy keylogger. Or the hardware keylogger requires a key combination to bring up the login and you can get to the data.
After comparing the differences between hardware keylogger and keylogger software, you may have understood that a powerful and secure software-based keylogger is much better than a function-limited hardware keylogger. At the same time, it’s worth mentioning that keyloggers are two-edged swords. They can be used for both good and evil, depending on how people use them and what the purpose is. Equipping yourself with knowledge about keyloggers is the best way to stop the bad and utilize it for positive.

What is the best GPS for you?
I don't know but here are some things to consider when choosing your next GPS.
How easy is it to move the GPS from your car to your bicycle to your motorcycle to being used for hiking? Make sure you select a GPS that is lightweight enough to carry while backpacking and has mounting options for all your vehicles & bikes. Select a unit with a high degree of versatility.
Batteries / Power Supply:
Some GPS units come with a permanent internal battery and others have a battery compartment for a couple of double A's. Here are some pros and cons to each:
- Less cost associated with the purchase of new batteries.
- Continues to function under the high vibration conditions of a motorcycle handlebars.
- Long run time. Some internal batteries last up to 20 hours of continual use on a single charge.
- When the battery is dead it is dead. You must then connect the unit to a power source for an extended period to re-charge.
- Rechargeable batteries have a limited lifetime. Once the unit stops holding a charge it must be shipped back to the manufacturer to be refurbished.
- Batteries are plentiful, relatively inexpensive and available worldwide.
- As long as you have a supply of batteries, you can keep the GPS unit running indefinitely.
- Adds to the cost of operation.
- Batteries life is diminished due to the vibrations in the handlebars. I have had significant trouble with engine vibration causing the batteries to lose contact with the terminals and leave carbon deposits on the battery terminal ends. This caused the batteries to rapidly deplete. A vibration dampening mount might help resolve this issue.
The best solution I have found is to use a mount that powers the GPS from the bike and carry some spare batteries. When I'm riding I remove the batteries and run the unit bike power supply. If I want to remove the unit and still use it I pop in a couple batteries and I'm off and running (or walking).
These are a few of the consideration to take into account when selecting your next GPS unit.

Perth - A robot mini-sub hunting for Malaysian jet MH370 will make a second mission to the remote southern Indian Ocean seabed on Tuesday after aborting its first search as it encountered water deeper than its operating limits, officials said.The unmanned submarine, loaded with sonar to map the ocean floor, was deployed on Monday night from the Australian ship Ocean Shield, which has spearheaded the hunt for the Boeing 777 that vanished on March 8."After completing around six hours of its mission, Bluefin-21 exceeded its operating depth limit of 4 500 metres and its built in safety feature returned it to the surface," Australia's Joint Agency Coordination Centre (JACC) said, without detailing the exact depth of operations.
"The six hours of data gathered by the Autonomous Underwater Vehicle is currently being extracted and analysed," JACC said. The US-made Autonomous Underwater Vehicle (AUV) had been due to spend up to 16 hours collecting data.US Navy Captain Mark Matthews explained that the vehicle had exceeded its programmed operational limit and automatically resurfaced.Matthews, a search and recovery expert, said the crew would now refine the task to cope with the depth encountered.The US-made AUV Bluefin-21 would embark on a second mission during the day, weather permitting, JACC said.
JACC chief Angus Houston had announced on Monday the end of weeks of listening for signals from the plane's black boxes and the launch of submarine operations.The vehicle would survey the silty ocean floor for 16 hours at a time to gather a maximum amount of data, he said."Bluefin-21 is planned to redeploy later today when weather conditions permit," JACC added.
Malaysia Airlines Flight MH370 went missing en route from Kuala Lumpur to Beijing with 239 people on board. The cause of the disappearance remains a mystery, with no debris found despite an enormous search, involving ships and planes from several nations.


Everything You Need to Know About Electrical Junction Boxes in the Attic
When it comes to electrical installations, safety and organization are critical. In any residential or commercial building, electrical junction boxes play a vital role in providing a secure connection for electrical wires. In this article, we will dive into the specifics of electrical junction boxes in attics, including their purpose, types, installation, and important considerations.

Servo motors are small but they are powerful and highly efficient devices. They have been around for a long time and are used in wide range of applications. The features they come with make perfect fit for radio-controlled and remote-controlled toy cars, airplanes and robots. Also, servo motors and drives are widely used in in-line manufacturing, industrial applications, food and pharmaceutics services, robotics, etc. These small devices have a servo circuitry that is fixed right inside the unit and has positionable shaft. The movement of the shaft is determinate by the electric signal which also is responsible for the motor control.
Servo motors are made of a very simple set-up and to understand their way of working you need to look under the hood. They are composed of a small DC motor, control circuit, and potentiometer. The motor is attached to the control wheel and as it rotates, the resistance of the potentiometer is changing, so the control circuit can control the amount of movement including the direction. The power supply to the motor stops in the moment when the shaft is in the desired direction. Otherwise, the motor is turned in the wanted direction. The desired position is sent by electrical pulses through the signal wire and the speed is proportional to the differences between the desired and actual position. If the motor is far from the desired position it will turn fast, otherwise it will turn slow. This is known as proportional control.
Servo motors are controlled by an electrical pulse which is sent through the control wire. There are a maximum and minimum pulse and a repetition rate. The servo motors and drives can turn 90 degrees in any direction for a total of 180-degree movement.
There are two types of servo motors and drives DC and AC. AC models are generally used in industrial machinery as they can handle higher current surges while the DC motors are usually a better choice for smaller applications. DC motors are a cheaper option and they are designed specifically for continuous rotation.
As we mention in this article, servo motors are widely used. They are used in radio-controlled airplanes to control surfaces such as rudders, walking a robot, elevators, or operation grippers. In pharmaceuticals and food services, servo motors are used in harsher environments where the level of corrosion is high so they help to maintain hygiene standards. You can find these motors used in the in-line production process as well, where the manufacturing requires precise work and high repetition.

One of the key moments in the composition of the conditions of possibility for a digital abstraction, within which certain logical operations might be combined, performed and arranged to carry out algorithmic computation took place in 1961 when James Buie who was employed by Pacific Semiconductor patented the Transistor Transistor Logic (TTL). This was an all transistor logic for analogue circuitry that crucially standardised the voltage configuration for digital circuitry (0v-5v). This represented a development from the earlier Diode–transistor logic (DTL) which used a diode network and an amplifying function performed by a transistor, and the even earlier Resistor–transistor logic (RTL) based on resistors which handled the input network and bipolar junction transistors (BJTs) as the switching devices. The key to these logic circuits was the creation of a representation of logic functions through the arrangement of the circuitry such that key boolean logic operations could be performed. TTL offered an immediate speed increase as the transition over a diode input is slower than using a transistor. With the creation of the TTL circuitry the logical operations of NAND and NOR allowed the modular construction of a number of boolean operations that themselves served as the components of microprocessor modules, such as the Adder.
I want to explore the importance of signal in relation to the interface between the underlying analogue carrier of the digital circuitry and the logical abstraction of digital computation – that is the maximisation of signal over noise in the creation of a digital signal carrier. It is exactly at this point that the emergence of digital computation is made possible, but also a suggestive link between signal/noise that points to the use of abstraction to minimise noise throughout the design of the digital computer, and which creates a logical universe within which computational thinking, that is signal without noise, or without noise as previously understood as thermal noise, is a constituent of programming practice. This is useful for developing an understanding between notions of materiality in theorising the digital, but also in making explicit the connection between digital “signal” and voltage “signal” or between the possibility of communication of information in a digital system.
At its most basic level standard TTL circuits require a 5-volt power supply which provides the framework within which a binary dichotomy is constructed to represent the true (1) and the false (0). The TTL signal is considered “low”, that is “false” or “0”, when the voltage is between the values of 0V and 0.8V (with respect to ground) and “high”, that is “true” or “1” when the voltage lies between 2.2V and 5V (called VCC to indicate that the top voltage is provided by the power supply, known as the positive supply voltage). Voltage which lies between 0.8V and 2.0V is considered “uncertain” or “illegitimate” and may resolve to either side of the binary division depending on the prior state of the circuitry or be filtered out by the use of additional circuitry. The range of voltages allows for manufacturing tolerances and instabilities of the material carrier, such that noise, uncertainty and glitches can be tolerated. This tripartite division creates the following diagram:
|Tripartite division of voltage in TTL digital circuitry|
This standardisation of the grammatisation of voltage creates the first and significant “cut” of the analogue world and one which was hugely important historically. By standardising the division of the binary elements of digital computation, in effect, the interoperability of off-the-shelf digital circuits becomes possible, and thus instead of thinking in terms of electrical compatibility, voltage and so forth, the materiality of the binary circuit is abstracted away. This makes possible the design and construction of a number of key circuits which can be combined in innovative ways. It is crucial to recognise that from this point, the actual voltage of the circuits themselves vanishes into the background of computer design as the key issue becomes the creation of combination of logical circuits and the issues of propagation, cross-talk and noise emerge at the different level. In effect, the signal/noise problematic is raised to a new and different level.

The optics is built of quality improved glasses. With a viewing angle of 135°, it provides a sufficient overview of the traffic situation. The fisheye effect is very small compared to many other car cameras in the low price segment.
Thanks to the high light transmission and large aperture of F2.0 also scenes with low light conditions – for example in the evening twilight or night – have crips details and good quality.
The polarizing filter allows the reduction of reflections in the windscreen, which are caused by the cockpit. The reflections of the cockpit details, for example vents or bright objects on the dashboard, can cover important details such as licence plates or street signs.
In the german version of “mini 0806” a CPL Polarizing Filters is already included.
The new OmniVision video sensor “OV4989” provides the technical basis for creation of a true HDR images. Compared to conventional WDR technology two differently exposed images are settled at a video frame. These “high dynamic range” videos recording more details in dark and light areas compared to “wide dynmaic range” video.
The HDR video stored in FullHD (1920×1080 pixels) resolution at 30 frames per second.
The video data is compressed using the latest H264 codec and saved as MP4 (*.MOV) file. The result is beautiful and can be played on many modern players (TV memory slot, laptop, PC, mobile phone).
256 GB Memory
There are two memory card slots available. Each can accommodate 128 GB of microSDXC memory. So there is a huge storage capacity of 256 GB for video recordings.
This corresponds to a recording time of approximately 40 hours at FullHD best quality.
The GPS receiver is discreetly placed in the ultraflat mount. This is also a good position directly on the windshild with a clear view to the sky.
The position data updates are done one time per second (1Hz). The user has the choice of display the speed and GPS coordinates in the video. The GPS data stream is also stored separately on memory using the popular NMEA format.
The mounting bracket is reduced to a absolute minimum of size to support an easy and stealthy installation. The Installation will be done with very strong adhesive pads.
To compensate for the curvature of the windshield in the hoizontal direction, small platelets with 2° and 4° are included in delivery.
The iTracker mini-0806 can be swiveled vertically. In conjunction with the small platelets the car camera can be accurately aligned to the roadszene.
The installed Mini 0806 is very unobtrusive and almost invisible – contributing to the very small housing dimensions. Logos, labels or other “conspicuous” features has been omitted in visible range.
Only the “German” version of the Mini 0806 has the extra matt surface finish, which reduce reflections on the body of the dashboard camera.
Despite the tiny size of the camera, a 1.5″ TFT display has been integrated.
The display of the german “Pro” version is protected behind a transparent plate, which seals the complete control of the back too.
In dependency of the country language, where the Mini 0806 is available, the menu has the local language installed. For example english language in US and UK, russian language in Russia, german language in germany.
It comes with a software included, to play easily the recorded dashcam video and simultaneously identify the location of the vehicle at Google Maps. Also, data such as speed and GPS coordinates are displayed together with the video.
For example if the driver was flashed or marked by police, he may afterwards check his speed and also the signs on the route again.

Popular satellite converters (Heads) The converter (head, LNB- Low Noise block) is one of the most interesting and important components of a satellite dish. A satellite dish cannot exist without a converter, because it is he who plays an important role in receiving a signal, which, as a result, is transmitted to the satellite receiver. In the markets of our countries, converters of two ranges are often found: C-band; Ku-band. The heads of these https://it.reviewing.site/page-sony-lf-s50g-recensione-caratteristiche-della-novita-don-t-riscattare-questo-costoso-altoparlante-con-lassistente-google bands are completely different from each other.
The C-band converter accepts all signals of its frequency and is not suitable for reception in the Ku-bands. It is for this reason that different converters (Linear and Circular polarization) are used. Converters with a lower noise figure can be installed on antennas of a smaller diameter, while the picture quality does not change at all. A huge variety of satellite heads are offered to you by different manufacturers. The signal quality directly depends on the quality of the selected head.
Several converters can be installed on the satellite dish at the same time, which will allow you to receive a signal from other satellites and thereby add a variety of channels. For satellite television Tricolor TV and NTV Plus a head of circular polarization is used. Converters with two or more outputs are very popular.
If you buy a converter (Head) for 2,3,4 outputs, this will allow you to split the signal into several devices.


Phantom loads, parasitic power, vampire power, so many names for the same thing; your electrical devices slowly making you poorer! These terms all refer to the power drawn by electrical devices that are plugged in but not being used, yet still drawing power. Think of power supplies plugged into the wall, computers, TVs, kitchen appliances, fire alarms, and garage door openers. All of these draw some power, even when not being used. Some items can draw considerable standby power that really adds up. This article will detail our process for tracking down and taming electrical gremlins.
AEP Power Bridge and Kill A Watt Meter
Our interest in this topic all started after attending a fair in our town where our electricity provider, AEP, had set up a booth to promote energy efficiency. For a limited time they would send you a free Power Bridge (link for AEP customers), so you could monitor your homes power usage in real time via a mobile app. Very cool! I download the app and waited for the Energy Bridge to arrive. After plugging it in and going through a simple setup, we could see our power consumption in real time. The Power Bridge uses your Wifi or Ethernet connection to link up with your smart meter. By being able to see power consumption, we could gauge how much power was being used when we were not using anything in the house, or our phantom load.
The energy bridge gave us an idea of our total power usage, but to track each load individually, we would need a different tool. A Company named P3 sells a product named Kill A Watt that performs the same functions as our energy bridge but for individual appliances. During our hunt for power robbing devices, we used both the Kill A Watt and the power bridge. If you do not live in an area with smart meters and the ability to get a power bridge from your electric company, you can use this same process with just a Kill A Watt meter. The device is fairly simple to use, just plug in the appliance to the meter and plug the meter into your outlet. Here we were checking the can opener, which does not draw any power when it is not being used.
We started off monitoring our current electrical usage. There are quite a few items in our house that use electricity in the middle of the night or when we were out of the house. This includes our aquarium, outdoor lighting, HVAC, and anything that may be plugged in but set to “off”. Our lowest power consumption was around 225 watts. When we are home cooking, doing laundry, or watching TV, our consumption is much higher. Our highest energy usage in the past month was over 6,000 watts or 6kW.
The AEP Energy Bridge App.
Now that we had our baseline phantom load of 225 watts, we could start to hunt for ways to reduce that level. Below is a table of the devices we tested while “off”/standby vs being used.
It is very interesting that some devices do not actually consume any power, or consume negligible power, when plugged in, but are not in use. You can stop having nightmares about your iPhone charger driving up your electric bills when they are not charging a phone because they consume less than .1w. The Kill A Watt showed 0 watts being used by an iPhone Charger in standby. But even at 0.1w, it would take over a decade to cost a mere $1 in electricity.
How to Calculate Annual Electrical Costs
An interesting shortcut to calculate the annual cost of something that is always on, is to simply take the number of watts and turn it into dollars. For example, a 17w load will roughly equal $17 in electricity if left on at all times. This estimate holds true at our energy costs of $0.11 kWh. The math behind this is as follows: (24hours a day) x (365 days per year) =8,760 hours per year; take that times 1 watt to give you 8,760 Wh, or 8.76 kWh per year. Now 8.76kWh x $0.11/kWh is $0.96 in annual electrical usage, or 1 watt= ~$1.
How to Improve Energy Efficiency of Phantom Loads
Some items we had definitely needed improvement. The computers and aquarium were both areas where we could optimize. So, what can you do to improve? Well the first thing would be to unplug any unused or seldom used devices. Next, you can look at reducing the power consumption by using a smart outlet or smart power strip. There are several variations to these power strips.
Use a Smart Strip
A smart strip is able to use the power consumption of one device to control power to other devices. When one device, such as a screen, is on, the other items will be on as well. This works great for a TV with a bunch of other attached electronics. When you turn the TV on, all the other items used with the TV can now be turned on as well. When it is not in use, your Blu-ray player, speakers, gaming systems and other devices behave as if they are unplugged.
Use A Smart Outlet
Another variant of the smart power strip is the smart outlet. They sell so many styles of these today it is hard to keep track. You can have them controlled by nearly anything you can imagine, from your phone to your smart home controller. We have come a long way from “clap on – clap off”!
Review Each Power Consuming Item
You can also look at using more efficient versions of a product. For example, we recently went from a fluorescent fixture to an LED fixture for our fish tank. The old fluorescent fixture was drawing around 46w and 2.3w when off, while the new LED fixture draws 0.9w when off, and only 15W when on! That’s a 60%+ reduction. I also insulated the bottom of the tank to help minimize the amount of time the electric heater is on.
Consider Other Ways to Reduce Energy Usage
What about items that are now always on, but are used in varying amounts, like your clothes dryer, hair dryer, or aquarium heater? The Mrs. wrote a good post on the clothes dryer that you should definitely check out. I took a deeper dive into the aquarium electrical consumption and hair dryer. For the aquarium, I attached the Kill A Watt to the power strip and let it run for a few days. This would track everything in use on the aquarium. The Kill A Watt is capable of looking at the cumulative electrical consumption as well as the instantaneous usage. The cumulative consumption of the aquarium was 6,460w over 4 days, which costs me $0.18 per day. These measurements were all taken after the upgrade to the LED light. Unfortunately, there is not much I can do about the electric water heater, other than better insulate the back and bottom of the aquarium. I also have to note that this is the winter time and the house is significantly colder than the aquarium. In the summer time the house is right at the desired aquarium temperature, so I would not expect the electric heater to be running half the year. I plan on revisiting this in the summer and will post a comparison of the power consumption in summer as well.
Sam was nice enough to allow the Kill A Watt to be hooked up to her hair dryer for a week. During that time, her daily usage averaged 0.11kWh, which is roughly equivalent to $0.01 per blow dry. Not too bad! Over a year, it only runs us $3.65 for daily use of the blow dryer.
Now for the really awesome part, some libraries allow you to borrow a Kill A Watt meter free of charge. This is not a widely known fact. Even the first librarian I spoke with had never heard of this item being offered. But some quick searching on the library website revealed, not just the power meter, but a whole host of other items available to borrow at the library. Everything from jumper cables, to wireless hot-spots. Check out a meter and start poking around, you never know what you might find.
