Electric generators are devices that use alternating magnetic fields to create a current through a wire circuit. While full scale models can be complex and expensive to build, you can create a simple electric generator easily. All you need to do is create a simple frame to hold the wire and magnet, wind the wire, connect it to an electrical device, and glue the magnet onto a spinning shaft. This even works well to teach electromagnetic properties, or display as a science project.
STEP1: Building the Frame
1Cut the cardboard. Cardboard will serve as the frame and support for your simple generator. Use a ruler to measure a cardboard strip that is 8 centimetres (3.1 in) by 30.4 centimetres (12.0 in). Cut this strip out with scissors or a utility knife. This single piece will be folded to form the frame.
Mark the cardboard. Use a ruler to measure along the length of the cardboard. Make your first mark at 8 centimetres (3.1 in). Your second mark should be at 11.5 centimetres (4.5 in), and your third mark should be at 19.5 centimetres (7.7 in). The final mark will be at 22.7 centimetres (8.9 in).
- This creates segments of 8 centimetres (3.1 in), 3.5 centimetres (1.4 in), 8 centimetres (3.1 in), 3.2 centimetres (1.3 in), and 7.7 centimetres (3.0 in). Do not cut these segments.
3Fold the cardboard. Fold the cardboard along each mark. This will make your flat piece of cardboard into a rectangular frame. This frame will house the components of your electric motor.
Slide the metal shaft through the support frame. Push a nail through the center of the cardboard frame. Make sure you go through all three pieces of cardboard that are folded into the center. This will create the hole for your shaft. You can now insert a metal shaft, or use the nail as your shaft.
- The metal shaft does not have to be anything in particular. Any piece of metal that will fit through the hole and come all the way out the other side of the frame is acceptable. The nail you use to make the hole will work perfectly.
1Wind the copper wire. Make several turns around the cardboard box with enamel coated copper wire (#30 magnet wire). Wind 200 feet (61 m) of wire as tight as you can. Leave about 16 to 18 inches (40.6 to 45.7 cm) of wire loose on each end to connect to your meter, light bulb, or other electronic device. The more “turns” or winds you make around the cardboard frame, the more power your generator should produce.
2Strip the ends of the wire. Use a knife or a wire stripper to remove the insulation from each end of the wire. Remove about 2.54 centimetres (1.00 in) of insulation from each side. This will allow you to connect the wire to an electronic device.
3Connect the wires to an electronic device. Attach the two wires you have loose at the ends of the windings to a red LED, #49 miniature bulb, or a 1.5V grain-of-wheat lamp. Or, connect the test leads from an AC voltmeter or multimeter to them. Keep in mind that you are producing a very low voltage, and larger devices (e.g. a regular light bulb) will not be powered by this generator.
Glue the magnets to the shaft. Use a high strength hot melt glue or epoxy to glue four ceramic magnets to the shaft. You want the magnet to be stationary with respect to the shaft. The magnets should be glued onto the shaft after the shaft has been inserted into the frame. Allow the glue to dry for several minutes (the instructions on the container can tell you exact drying times for your type of glue).
- For best results, use 1x2x5 cm ceramic magnets (these can be found online for a reasonable price). Glue them so that two magnets are facing the coil with their north side, and two are facing the coil with their south side.
2Turn the shaft with your fingers. This allows you to see if the ends of the magnets hit the inside of the frame. The magnets must turn freely, but as close as possible to the walls of the frame. Again, having the magnet’s ends as close the copper wire windings as possible will increase the “exciting” action of the magnetic fields the magnet produces.
Spin the shaft as fast as possible. You may want to wind a string around the end of the shaft, then pull it sharply to turn the magnets. You could even just spin it with your fingers. As the shaft turns, you should get a small voltage (enough to light a 1.5 volt light bulb).
- You could improve the power output by putting a pinwheel on the end of the shaft and connecting it to an electric fan to turn the wheel. Keep in mind that this is only good to demonstrate the operation of the generator since you use more electricity turning it than you create.

So, I got the new (used) CPU I was waiting for. If that’s confusing, what I mean is I bought it used, but it’s new to me.
Anyway, I’m writing this post on the newly updated computer and it’s working great even though it’s more CPU than the motherboard is supposed to be able to handle. Windows recognizes and properly identifies the CPU just as it did the memory, so I’m confident that it’s working properly. I double checked the power supply and it’s 250w so I don’t think there will be any issues with added power requirements of the upgraded CPU.
So far it’s running great, but I’ll be keeping my eye on things for heat issues over the next couple of days.
I will say that the biggest improvement in performance came from adding the memory, but the new CPU made a noticeable difference as well, especially when starting up and when running multiple programs at once.
So, I took a 13 year old computer, spent about $50 putting in (more than) the maximum processing power and memory it can handle, and now I’ve got a computer that’s running almost as fast as my 2 year old company provided laptop (at least by my perception). I’m happy.
Anyone wanna buy a slightly used AMD Athlon II 170u CPU and/or a 2gb DDR2 PC-6400 memory stick? If not, I’ll probably add them to my antique computer parts museum in the attic.


We are in the first quarter of 2024, so we have already witnessed several premieres of flagship smartphones from leading manufacturers. Samsung showed its Galaxy S24 models, OnePlus globally presented the 6.82-inch “twelve”, Xiaomi 14 will soon appear in stores (although there is still an Ultra model on the way) and at the moment we are still waiting for moves from other major manufacturers. And everything would be perfectly fine, if it weren’t for the fact that from year to year the general excitement about new models seems to be decreasing. It is easy to see that over time, new products are distinguished by only a few details, for which it is often not worth giving up your smartphone. With this issue in mind, the question arises: where is the overall market heading? After years of rapidly succeeding revolutions, have we already achieved the so-called a critical point in the development of mobile phones?
Author: Piotr Piwowarczyk
Stagnation in the world of smartphones has been talked about for a long time and longer texts have already appeared on our pages. The whole topic did not arise completely by accident. Almost every new premiere is associated with various impressive renderings and presentations of models, which, however, at first glance look almost the same as the previous ones and do not surprise anything even in terms of specifications. A new top processor is, of course, a must-have for such devices, but apart from that, companies often use the same capacitive variants, identical sets of cameras (the Galaxy S24 and S24+ models are a very good example), and the front is most often decorated with a large AMOLED screen with a notch. It’s no wonder that those who bought a flagship device three or even four years ago often still see no reason to change, especially since almost all large manufacturers offer multi-year support with system updates. Given all these facts, a thought occurred to me. Doesn’t all this mean that modern smartphones have become… perfect in their form?
For several years now, smartphones have been lacking absolutely nothing. Does this mean that we will see further slow evolution in the coming years? Or maybe big changes are just around the corner?
Please note that for several years now, smartphones have lacked absolutely nothing. A 5000 mAh battery has become a standard, so it is difficult to find a model that discharges itself during the day with normal use. AMOLED screens with infinite contrast, high brightness and a refresh rate of 120 Hz cover the surface of almost the entire front panel – only the cutout for the front camera or Face ID stands out. The processors, in turn, are so efficient that they allow you to play games that look like current-gen productions from PC or consoles (see Resident Evil 4 Remake on iPhone 15 Pro). And cameras? Well, they still haven’t caught up with classic SLR cameras, but in the eyes of many users they are really close to being perfect. What’s more, sometimes they even perform equally well in some shots. So let’s consider what the next years may bring.
Samsung said its smartphones are more disappointing than iPhones. The Galaxy S series may see some changes
Given the current situation, can manufacturers rest on their laurels and congratulate themselves on creating perfect devices? Well, of course not. There will always be room for maneuver, some space in which further improvements will be possible. The SoC system seems to be an obvious element for continuous, although at the same time less and less visible improvements. Each year, Apple, Qualcomm, MediaTek and Samsung present their new top units, which beat their predecessors in terms of performance and at the same time offer support for more modern communication standards and various technologies. However, even here it is increasingly difficult to count on significant progress, which is clearly visible in the results in the AnTuTu benchmark. The technological process is not decreasing as rapidly as it was a few years ago, so it is difficult to make solid progress in the field of energy efficiency.
Qualcomm Snapdragon 8 Gen 3 vs Samsung Exynos 2400 – test of SoC systems from Samsung Galaxy S24 smartphones. Which is better?
A step forward may be various functions related to artificial intelligence, thanks to which we can quickly correct a photo or recorded video, as well as translate notes or a telephone conversation. Samsung is trying to lead in this field with its Galaxy AI solutions, but honestly, it’s hard to get excited about them seeing how noticeable progress has been made in this field in recent years or months. The South Korean giant, of course, did a great job of implementing most of these solutions directly in the devices and presenting them to the user at the first opportunity. The only question is how many of them will actually be useful to users? Personally, I am of the opinion that the people who will benefit most from the Galaxy AI functions are… students, for whom the options of recording and transcribing lectures or sorting and summarizing notes will prove invaluable. For the rest of ordinary consumers, most new features will prove to be merely interesting curiosities and nothing more.
Artificial intelligence is taking a more physical form. LG presents small robots that will assist us at home
While in the coming years we can expect new software functions or higher performance guaranteed by more and more powerful processors, everything indicates that only the details will change in terms of device design. As we can see, in recent years the design of devices has been determined by prevailing trends. That’s why newer devices are usually characterized by an angular frame in the style of the latest iPhones (I have a feeling that titanium will become more and more popular), increasingly larger photographic modules, and on the front – as has been the case for several years – we see a screen with a large surface with a small “hole”. ” to the front camera. Unfortunately (or maybe fortunately?) there is little indication that under-screen cameras will be widely used in the coming years. Even though a small number of high-budget smartphones feature such a solution (e.g. Galaxy Z Fold5 or Nubia Z60 Ultra), it still seems so expensive, advanced and at the same time imperfect that manufacturers may simply skip this effort. at least the next few years.
A smartphone with all the lenses placed under the screen? Xiaomi has just submitted an application to the patent office
It seems that not much may change in the case of screens either. In fact, AMOLED panels with a variable refresh rate seem to be an ideal solution and it is difficult to think of something better at the moment, especially since increasing the resolution or artificially increasing the peak brightness does not make much sense (it is very rarely useful and generally causes the battery to drain faster). . When it comes to photography, there is actually little to criticize today, even for budget cameras that can afford great shots not only during the day. Flagships – as I mentioned earlier – can successfully replace separate cameras today. It is worth watching what Chinese manufacturers, including Vivo, Xiaomi and Huawei, offer in these matters today, who, for example, increasingly offer cameras with a 1-inch matrix. Although, of course, Apple, Google and Samsung also offer good photo smartphones, they seem to be a bit behind in terms of overall capabilities.
Comparison of the quality of photos and videos from Samsung Galaxy S24 and S24 Ultra smartphones. Can you see the differences and is it worth paying extra?
It is also worth noting that over the years, little progress has been made in terms of battery life. So what if many cheap and medium-budget models now offer cells with a capacity of 5000 mAh, if our pocket devices still have to be charged every day? We have been waiting for a revolution in this respect for many years and it is possible that only the popularization of graphene may change something in these matters. However, when it comes to charging speed, it is different. Today, there is no shortage of smartphones that you only need to connect to the power supply for a moment to enjoy many hours of operation. It’s a pity that many manufacturers are in no hurry to introduce this technology to their devices. While relatively cheap models from the Middle Kingdom support charging with a power of e.g. 65 W, the largest players in this industry stubbornly stick to offering charging in the range from 20 to 30 W. Some will argue that this way the battery life is protected, but after all Battery degradation is often visible after two or three years of intensive use.
There will certainly be no shortage of exciting projects in the future, e.g. with expandable or transparent screens. However, the key question will be whether such inventions will be useful and practical at all? It may turn out that people will want to stick with conventional smartphones anyway…
Will Apple Vision Pro goggles soon breathe new life into the VR/AR market? Meta strongly believes in this
Although smartphones may evolve over the next few years, we can be sure that in addition to boring models, there will certainly be exciting designs, e.g. with roll-up or transparent screens. However, the key question will be whether such inventions will be useful and practical at all? It seems that foldable smartphones may be a sufficient warning, as they are constantly being improved and are more durable than you might think, but users are still plagued by various types of failures (including those related to the hinge), inconveniences (e.g. short battery life) or for example, the need to regularly replace the protective foil. Considering the great expense involved, conventional models are still the most reasonable choice. So, no matter how trivial our smartphones would be, it seems to me that they are actually the most complete and multifunctional today. Without a doubt, they are today a safe choice among many technological innovations and, in fact, it is difficult to reinvent them. If we want to look for future solutions, it would probably be better to look towards AR glasses, VR goggles or other such devices.

Communication has never been as easy as today where almost everything can be done electronically. Before, to be able to talk to someone via video phone, you would need very powerful satellite equipments. But now, you can simply go onto the internet and talk via webcam. There are numerous webcams out there but only a few stands out. Among them is Logitech’s Quickcam Ultra Vision.
So what makes Logitech’s Quickcam Ultra Vision different from the others? On the top of the list would be the video and picture quality. The camera is capable of displaying and receiving 4 megapixels. Since Quickcam Ultra Vision can use the USB 2 interface, it won’t have any problems sending data between the PC and the camera. Just make sure that your computer does have USB 2 ports. Aside from the quality of the pictures, the speed and response time of the camera is excellent. The movements are really smooth and it’s not that far away from looking as if you’re actually talking to the person right in front of you. It can run at 30 frames per second.
Aside from the picture and video quality, there are other neat features such as the right light technology which automatically adjusts lighting for you. It’s very helpful if you’re just in your room with dim lights. You can take pictures as well using its snapshot feature. You can press the snapshot button at the side of the camera just like a digital still camera and your picture will automatically be saved onto your computer.
It has very clear audio input and whoever you’re speaking to can easily understand what you are saying. It does capture even background sounds but you won’t find it as disturbing as it sounds on a regular telephone.
The camera can also be easily set up using Logitech’s software. You can adjust the microphone’s sensitivity; you can set the quality of the video and test them before actually using them for transmitting videos. Plus, it’s compatible with almost any of the most famous messaging services such as Skype and Yahoo Messenger! A video call is just a few clicks away!
It can also be easily mounted on top of your monitor with its adjustable clip regardless if you have a CRT or an LCD-type monitor. As for its price, it’s available at around $85-$95. You just have to look around to see if you can find a better deal. It’s still widely available at your favorite electronics and online stores.
There are very few webcams that stand out among the myriad of available webcams out there. Logitech’s Quickcam Ultra Vision won’t disappoint if you want to have clear video transmittal using your computer. My family and I have been using this camera to communicate halfway around the globe and we’re truly impressed with its performance and quality.


The Osram LUW CP7P-KTLP-5C8E-35-Z is a rather inexpensive LED with some fairly impressive specs. Digikey pricing is $2.47 at 1200 piece quantities.
The specs are the following;
- 109lumen at 350mA
- 243 lumen at max current 1A (assuming one can keep it cool)
- Viewing Angle 80 deg
- Color: Cool white, 6500K
- Size 3mmx3mmx2.23mm high
A full data sheet is available at http://media.digikey.com/pdf/Data%20Sheets/Osram%20PDFs/LUW_CP7P.pdf
The big problem with the above is temperature. Low cost FR4 PCB’s will not provide enough heat sinking.
The Cree MX3AWT-A1-R250-000C51 is another inexpensive LED, running about $1.87 at 250 piece quantities.
The specs are as follows.
- 67 lumen at 350mA
- 100 lumen at 400mA (assuming one can keep it cool)
- Viewing Angle 120 deg
- Color: Cool white 6500K
- Size: 4.65mmx4.65mm
A full data sheet is at http://www.cree.com/products/pdf/XLampMX-3.pdf
Whats nifty about this part, is that one can use a double sided FR4 pcb and through the use of vias under the paddle achieve adequate thermal performance.

Magnetic Field Viewing Film
Magnetic Field Viewing Film is a soft magnetic pole detection sheet containing magnetic powder. This tool allows you to easily determine the orientation and number of magnetic poles on a magnet through the induction of magnetic field polarity.
Simply place the magnetic wave card close to the magnetic material, and you can observe the magnetization method and count the number of magnetic poles.
As you approach a magnetic substance, the magnetic wave card reveals two distinct parts – a bright area and a dark area. The bright area signifies the magnetic field lines parallel to the card’s surface, where liquid magnetic powder reflects light. This region allows light to penetrate more easily compared to the dark areas (representing magnetic field lines perpendicular to the card’s surface). Utilizing the interaction of light and dark areas provides an easy and convenient method to identify magnetic poles.
When not in use, avoid prolonged contact with magnets to prevent permanent marks on the magnetic card.
The magnetic wave card can detect the direction and number of poles in the magnetic field but cannot determine whether the polarity is North (N) or South (S).
Discover the fascinating world of magnets with our Magnetic Field View Film – a simple and effective tool for exploring magnetic properties!

SOLAR PUMP CONTROLLER WITH RELAY
Buy now from the REUK Shop
Home > REUK Shop > Solar Water Heating
First class Postage and Packaging on all orders is just £2.45 in the UK.
To view your shopping basket click here.
Additional InformationThis circuit is an alternative to our popular Solar Pump Controller Circuit (described in the article: Solar Water Heating Pump Controller) supplied with a fitted relay.
NEW 2013 - This 2009 controller is now available at a lower price. Our new improved for 2013 solar water heating pump controller with relay is now available here: buy 2013 Solar Pump Controller with Relay with many added user requested features and improvements.
This design of solar water heating pump controller is based around a PIC microcontroller - to all intents and purposes a computer-on-a-chip. This has given us the flexibility to produce a pump controller which meets the exact needs of our customers. The operation of our standard version is described below, however we can programme the microcontroller to operate according to different specifications if required. (Contact details are provided below for bespoke pump controller enquiries).
Temperature SensorsTwo LM335Z precision temperature sensors are provided pre-soldered to 100mm insulated leads. The soldered joints are covered with heat-shrink tubing to prevent short circuits and protect against corrosion. One temperature sensor is for the solar water heating panel, and the other for the hot water tank. Some terminal strip is provided to enable you to connect the sensor leads to the long cables (not included) which you will use to connect your solar heating panel, water tank, and this control circuit.
The first temperature sensor should be stuck to the copper pipe just where it leaves the solar heating panel, the second should be stuck to the outside of the hot water tank underneath the insulation. We recommend that you use heat sink adhesive (more usually used to stick heat sinks to the tops of processors in computers) to attach the sensors to the pipe and tank. This type of adhesive conducts heat very well ensuring accurate temperature readings, and it will hold the sensors securely in place.
Pump Controller OutputThe microcontroller monitors the temperature of solar water heating panel and the hot water storage tank. Basically, if the panel is hotter than the tank we want the pump to switch ON - so we can increase the heat of the water in the tank; if the tank is hotter than the panel then we want the pump should be OFF - we don't want to cool the water in the tank by pumping from the solar panel.
In reality, things are a little bit more complicated. For example, when the temperature of the tank and panel are nearly equal, there is the risk of the pump being switched on and off rapidly - a sure fire way of damaging the pump and also wasting energy. Therefore, the controller is programmed to turn on the pump only if the temperature of the panel has been hotter than that of the tank constantly for 30 seconds. Similarly, the pump once switched on is kept on for a minimum of 20 seconds so a sudden (unlikely) drop in panel temperature will not cause the pump to switch immediately off .
The RelayA 12V relay is fitted to the circuit board through which a suitable pump can be switched. The relay is rated at 10 Amps - corresponding to a pump with a peak power rating of around 120 Watts at 12 VDC. An LED bulb gives a visual indication of whether the relay switch is closed.
Above is a diagram to show how this controller circuit should be connected into a solar water heating system.
Powering the ControllerThis is a 12VDC powered device, and so should be powered either by a solar charged or otherwise 12V battery or with one of our mains plug-in 12VDC power supplies.
Warning about Mains Powered PumpsAlthough the fitted relay is rated for use with 240VAC mains electricity, this circuit should not be used directly to switch a mains powered pump (for example the circulation pump from a mains powered boiler). If you intend to use a mains powered pump, then a secondary relay on a completely separate (correctly earthed and insulated) circuit board must be used. Consult with a qualified electrician before attempting this sort of work.

Veterinary college lab leads exploration of DNA sequencing advances
August 29, 2023
The ability to examine up to 2 million DNA bases instead of just a few hundred in a single read and get results in under two weeks instead of months with a device costing about $1,000 instead of 100 times as much would certainly seem like a win-win-win proposition.
The Virginia Tech Animal Laboratory Services (ViTALS) within the Virginia-Maryland College of Veterinary Medicine has secured a $200,000 grant from the National Animal Health Laboratory Network (NAHLN) to develop further expertise internally on nanopore-based genome sequencing for pathogen detection and disseminate that acquired knowledge to other laboratories.
Nanopore technology leader
“At the veterinary college, we have been working the last seven or eight years to develop expertise in deep sequencing, especially with this nanopore technology,” said Kevin Lahmers, clinical professor in anatomic pathology at the veterinary college and head of research and development at ViTALS. “And we are recognized as one of the leaders in that area in veterinary diagnostics.”
Nanopore sequencing is a technology in which DNA is fed through microscopic holes along with electrical current. Computer algorithms detect changes in the electric current which can be interpreted as one of the four bases in DNA, establishing the sequence.
More cost effective, efficient
Most DNA sequencing now is by synthesis, Lahmers said, a more complex process in which nucleotides are matched up with a single strand of the double-helix DNA, and those nucleotide additions are detected by color or changes in acidity or electrical charge.
Nanopore sequencing can be performed on equipment “the size of a stapler, costing $1,000,” Lahmers said, whereas synthesis requires larger equipment costing around $100,000. Only about 350 bases at a time can be detected by synthesis, often taking several weeks to complete the analysis, whereas “if you can be gentle enough with the DNA” up to 2 million DNA bases can be read by nanopore sequencing, results ready in 1 to 2 weeks.
While much of the grant focuses on training for more individuals within the veterinary college and further study of how nanopore sequencing works with known pathogens, another purpose is to spread the knowledge that is obtained to other laboratories, including a cloud-based workspace to share information on bioinformatics and sequencing processes.
The end goal is to increase the pool of individuals and laboratories capable of using nanopore sequencing technology to identify emerging pathogens and connect DNA sequences found in lesions to those pathogens through a process called in-situ hybridization.
“What we are proposing is to share what we've learned and what we've developed with the veterinary community, potentially having people come to Virginia Tech to train, so that we have more people with that expertise,” Lahmers said. “It's great to be a leader. But if it's just one group doing this, then that's not really efficient. Part of this is to disseminate knowledge, so that more labs are capable of doing this.”

Are You Thinking About Big Data When Doing IoT? – You Should Be | @ThingsExpo #ML #IoT #M2M #BigData
Blog This Are You Thinking About Big Data When Doing IoT? - You Should Be There is no denying the Internet of Things (IoT) is a hot topic. Gartner positions IoT as being at the peak of the ‘hype cycle.' From a size perspective, these ‘Things' can be anything, from a small sensor to a large appliance, and everything in between.


Our Featured Project
A Solar Birthday Gift Residential Projects
Options to prevent or manage power outages are developing every day. When a power outage occurs, not only do the lights go out, but the refrigerator stops running, cell phones and laptops can’t be charged, and even more critical, medical equipment that people depend on loses its power source. Depending on how long the outage lasts–and with recent weather, it could be days–this results in food loss for both families and companies like grocery stores and restaurants, no communication outlets during an emergency, and far worse for individuals and facilities that rely on power to keep life-saving machines operating. Yes Solar Solutions offers effective options like a sealed gel battery backup to a solar system that can handle critical loads, such as powering refrigerators, microwaves, well pumps, and lights in several rooms. Yes Solar even has its own sealed gel battery backup system that backs up our server and lights in case of emergency. While an option like this is useful, there’s a new solution that we’re excited to bring to home and business owners across North Carolina.
The Tesla Home Battery
Yes Solar Solutions is proud to have recently become a Tesla Energy Certified Installer of the Powerwall. The Powerwall is a home battery that charges using electricity generated from solar panels during the day and powers your home during the night. It also protects your home against power outages by providing a backup electricity supply. This innovative new option is easy to install, takes up little space, and operates automatically. The Tesla Powerwall offers you freedom from the utility grid and the peace of mind knowing you have a plan during an outage. This is a safe, economical, low-maintenance way to provide your home with the solar energy storage more and more homeowners are realizing they need.
How the Tesla Home Battery Backup Works
Each Powerwall has a 6.4 kWh energy storage capacity, which is all that’s necessary to power most homes during the evening using the electricity the solar panels generate during the day. If your home needs more power, multiple batteries can be installed. How does it work? According to Tesla’s site, “A typical Powerwall system includes solar panels, an inverter for converting electricity between direct current and alternating current, a meter for measuring battery charge, and in backup applications, a secondary circuit that powers key appliances. Which components are required depends on how you use your home battery.” The solar panels collect sunlight and convert it into electricity. This charges the Powerwall battery, but the battery can also draw energy from the utility grid. An inverter takes the direct current electricity provided by the solar panels, grid, and Powerwall and turns it into the alternating current your home uses to power your lights, appliances, etc. This may sound bulky, but the system is actually quite sleek. For a more detailed description of the Tesla Powerwall battery and how it works, click here.
What This Means for NC Residents
Essentially what having the Powerwall does for residents is give them a reliable, economical, sustainable way to power their homes, even during outages. Being on the coast, North Carolinians see threatening weather often throughout the year. As a Tesla Energy Certified Installer, Yes Solar Solutions is able to give homeowners peace of mind. By planning ahead, homeowners can feel stable year-round knowing they have a battery backup system in place that’s always working for them, no matter what.

The term high voltage usually refers to any amount of electrical energy powerful enough to harm a living organism and cause significant property damage. There’s no exact definition of high voltage but according to NATIONAL ELECTRICAL CODE (NEC), it can be a voltage that’s over 600 volts. This can be based on two factors: the danger of electric shock and the possibility of causing a spark in the air. Equipment and conductors that transmit or use high voltage power require particular safety procedures.
High voltage is used in cathode ray tubes, in electrical power distribution, in high power amplifier vacuum tubes, in photomultiplier tubes, to demonstrate arcing, to generate X-rays and particle beams, for ignition, and other industrial, scientific, and military systems.
DANGERS OF HIGH VOLTAGE ELECTRICITY
The risks of electrical hazards are greater in facilities where operations rely on high voltage electrical systems. Accidental contact with high voltage energy may result in catastrophic injury or death. Exposure to high voltage causes instant shock to neurons and muscles in the body. In some cases, the body may throw itself a distance if the shock is strong enough. Being thrown a considerable distance or falling from a great height can cause significant physical injuries. If the voltage is applied across wet human skin, it can cause electrocution, which can result in heart failure and tissue damage.
The human body provides a path for current flow and when the high voltage energy passes through the chest area, it can cause a very strong heart attack. The chances of surviving high voltage electrocution are very low. Other injuries can include burns. Accidental contact with high current can generate an arc, which can totally cook a living tissue.
Such burns can be especially hazardous if a person’s airway is affected. High voltage currents travel at the speed of light and give you little chance to react. As such, it’s unlikely to come out alive in the event of accidental contact or failure in the system.
Apart from bodily injuries, an arc can damage electrical cabinets, wiring, and systems. A short circuit or interruption of high voltage current can instantly shut down an entire work floor. High-energy arcs can melt steel, start a fire or cause violent explosions. If such things happen in your facility, working anywhere near the power source or building can be extremely dangerous. As such, your facility may need to be shut down until the situation is corrected.

A member of our astronomy group Galileo presented some photos he took at the Gornergrat in Switzerland. One of those photos showed a neutron detector. Immediately I was curious what the purpose of this detector and the corresponding research was.
Electrons, protons, and neutrons are the main sub atomic particles in an atom.
Neutrinos are created as a result of certain types of radioactive decay, or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. The neutron detector detects neutrinos (and not neutrons as I first assumed). A neutrino is a sub atomic particle with a small mass (similar to electrons) and no electrical charge. Since there is no electrical charge, neutrinos are not affected by the electrical or magnetic forces. It is shown by the Greek letter nu. Three types of neutrinos have been described as electron neutrino, muon neutrino and tau neutrino. It is hard to determine neutrinos directly as they don’t carry a charge, and don’t ionize the materials they are passing through. The present detectors can only detect the high energy neutrinos.
The neutron detector in Gornergrat has been installed in 1998 in collaboration with the Solar-Terrestrial Environment Laboratory of the Nagoya University, Japan, and is the European cornerstone of a worldwide network of solar neutron detectors. There are also detectors in Armenia, Tibet, Hawaii, Bolivia, Japan and Mexico. Observations of solar neutrons can provide unique information on the acceleration of particles in association with solar flares and coronal mass ejections.
In contrast to charged particles emitted in association with solar flares and coronal mass ejections neutrinos are not affected by the magnetic field of the Sun, nor by the interplanetary magnetic field, nor by the geomagnetic field. Observations of solar neutrinos therefore offer a direct insight into the mechanisms of high energy processes at the Sun. The additional possibility to measure the energy spectrum of the neutrinos gives information about the timing and the duration of the high energy solar processes. This allows to get a better understanding of the acceleration mechanism of charged particles at the Sun. This information, along with measurements of solar gamma ray emission and charged particles, is the basis for building solar flare models.


A device resembling a plastic honeycomb yet much smaller than a bee’s stinger can steer light beams around tighter curves than ever before possible, while keeping the integrity and intensity of the beam intact. The work introduces a more effective way to transmit data rapidly on electronic circuit boards by using light.

The intraterrestrials, they might be called. Strange creatures live in the deep sea, but few are odder than the viruses that inhabit deep ocean methane seeps and prey on single-celled microorganisms called archaea. The least understood of life's three primary domains, archaea thrive in the most extreme environments: near hot ocean rift vents, in acid mine drainage, in the saltiest of evaporation ponds and in petroleum deposits.
During a panel at the South by Southwest Festival, NASA representatives discussed how citizen scientists have made a difference in asteroid hunting and announced the release of a desktop software application developed by NASA. The application is based on an Asteroid Data Hunter-derived algorithm that analyzes images for potential asteroids. It’s a tool that can be used by amateur astronomers and citizen scientists.
Research has demonstrated laser control of quantum states in an ordinary silicon wafer and observation via a conventional electrical measurement. The findings mark a crucial step toward future quantum technologies, which promise to deliver secure communications and superfast computing. The team demonstrated a quantum on/off switching time of about a millionth of a millionth of a second — over a thousand times faster than previous attempts
Albert Einstein is known in popular culture for his famous E = mc2 formula. Scientists know him for revolutionizing physics with his general theory of relativity.

Smart grids help avoid blackouts and deter cyber attacks. They also pose new challenges. As power generation — and the communication and information processing associated with it — shifts from centralized power stations to distributed, heterogeneous systems, massive amounts of sensor data from stations must be transmitted efficiently and effectively analyzed in real time.
Scientists have produced a new map of the Moon’s most unusual volcano showing that its explosive eruption spread debris over an area much greater than previously thought. A team of astronomers and geologists studied an area of the lunar surface in the Compton-Belkovich Volcanic Complex. By mapping the radioactive element thorium, which spewed out during the eruption, they discovered debris was able to cover an area the size of Scotland.
A newly discovered crocodilian ancestor may have filled one of North America's top predator roles before dinosaurs arrived on the continent. The "Carolina Butcher" was a nine-foot-long, land-dwelling crocodylomorph that walked on its hind legs and likely preyed upon smaller inhabitants of North Carolina ecosystems, such as armored reptiles and early mammal relatives.
