The idea is simple: If this sounds useful to you, here are a few things you should know before diving in. Starter Kits Come in Packs of Two Think of powerline adapters as a way to extend your network from Point A to Point B, wherein each point is an electrical outlet around your house. Because of this, powerline ethernet devices typically come in starter kits of two, as a single device is useless on its own. You can purchase more to extend your network around your house — just make sure all of your devices are compatible more on that later. Read More , you know that every network needs a router. Powerline ethernet devices are not an alternative to a router: A Simple Explanation Routers may seem complicated, but they’re actually quite simple. Here’s a quick guide to routers, what they do, and how they work. Read More , such as assign IPs.

He was in the process of testing 2 ‘dead’ displays and was able to exchange parts between them to diagnose the problem for each display… I ended up fixing one of the monitors by switching CCFLs between them, which confirms my belief that the most common problem among these older units, is related to the backlight bulbs.
The other monitor has a cracked LCD display. Remember that these bulbs work with high voltage around Volts and any small current variation at that level causes a much higher one at lower level, hence the need for protection circuits despite having a 3 Amp fuse at the ballast board. That explains why, sometimes, a more powerful power supply is able to correct it temporarily nevertheless. Another issue has to do with the high cost of the original power supplies been, most of times, twice the price of a defective monitor.
They have others with different specs also.

Comments The other weekend, I sat down and sorted through all my random electronics junk. As part of that process, I took all my power supplies and adapters and threw them into a box. It ended up being a pretty big box. Having so many chargers can be pretty frustrating. And once that happens, it can be incredibly difficult to figure out which goes with which. The default solution to this is to try random plugs until you find one that fits into your device.
However, this is a big gamble. If you grab an incompatible power adapter, your best case scenario is that it works, albeit not the way the manufacturer intended. The second worst case scenario is that you fry the gadget you are trying to power up. The worst case scenario is that you burn down your house. The following will cause damage to your device: Reverse polarity Higher voltage adapter than device rating The following will cause harm to your power cord or adapter:

Read More, you know that every network needs a ine ethernet devices are not an alternative to a router: they’re just a different way to connect devices to that router.
And there are a few best practices to keep in mind. An AeroVironment installer goes to work on a home unit. This does not include installation. Read on to see which key features—such as portability and connectivity—can send the price higher, or can be avoided to reduce the cost. The rule of thumb is that amp service will roughly give you the ability to add 30 miles of range in an hour—just as 15 amps will add about 15 miles in an hour of charging. These range numbers are somewhat optimistic.
A amp EVSE will need a circuit breaker rated for at least 40 amps. Think about the ideal location for this piece of equipment.

Stage and show lighting Lighting is important in theatre and shows. Lighting allows us to see the performers. Lighting provides a tool for setting moods and tones of scenes on stage. Different type of performanced have different lighting needs. Here are some typical lighting situations: Dance – Back lighting Theatre plays – a somwhow realistic looking combination of different lights Straight Theatre – Light through a window Stage lighting is achieved by the use of a large number of powerful stage lights, or lanterns or luminaires.
There are a great variety of these, for different applications, or of different make or vintage. So there are many different types of lighting instruments used in any theatre. Each type of instrument plays an important role in the overall lighting scheme. The most common light types used in theatres are plane convex lights, freshnels, profiles, which are the generic classes of spotlights. In addition to this floods are used for various applications.
Also used are PAR cans , but these offer little control and are used more in rock lighting than in theatre. Most luminaires use at least one lens, which is a piece of glass with one or both sides curved for concentrating or dispersing the light beam; this produces a variation in the beam angle and the quality of the light produced.

It contains a further circuits. This time we have concentrated on circuits containing one or more IC’s. It’s amazing what you can do with transistors but when Integrated Circuits came along, the whole field of electronics exploded. IC’s can handle both analogue as well as digital signals but before their arrival, nearly all circuits were analogue or very simple “digital” switching circuits. Let’s explain what we mean.

Mar 29, · Clocks That Aren’t Tied to Mains The cheapest built-in microwave I could buy certainly doesn’t have special time keeping. I’m now operating under a rule of thumb for identifying mains-tied.
March 29, Earlier in March we heard about a quirk of the interconnected continental European electricity grid which caused clocks to lose about six minutes so far this year. This was due to a slight dip in the mains frequency. An interesting set of conversations popped up from that topic. There were several claims that modern alarm clocks, and most devices connected to mains, no longer get their clock timing from mains frequency.
But what we really want to know is: I certainly could have been wrong.

The actual French legal ruling was published 7 February and then rescinded 3 July . CPR was withdrawn in March to be replaced by the equivalent norm CPR , representing Japan move from analogue to digital and thus letting analogue connectors as things from the past. It was adopted in Japan for the connector’s ability to support RGB output format no compression nor deterioration of original video signals but, contrary to SCART in Europe, it never saw widespread use on the consumer market.

Power Supplies A constant current source source can supply a fixed current to a load regardless of input voltage or load change. The LM is quite useful as a constant current source, works on a wide input voltage range, from 3V up to 40V. The circuit is rather simple, uses only one transistor and few passive components and performs well in terms of frequency stability, almost zero drifting after about 4 hours of continuous operation. With 12 volt DC it will deliver 1 watt RF power. The most important parts of the oscillator are the transistor Q1 and the tuned circuit, which comprises the inductor Ll and the variable capacitor CV1.
When the battery is first connected, a brief surge of current flows from the collector to the emitter of Q1, causing an oscillating i. An oscillating voltage therefore appears at the junction of Ll and CV1. The frequency of the oscillation depends on the values of Ll and CV1, so that varying the value of CV1 tunes the oscillations to the exact frequency required. In order to achieve a high output level, you will need a well tuned antenna, and a large heatsink to dissipate the heat from T2 transistor.
Transmitter was mounted in metal enclosure and works extremely well. Test and Measurement I finally got round to making my capacitor ESR tester this week after finding a nice simple 5 transistor version. I will not be going into much detail regarding ESR or Equivalent Series Resistance Meters as, there is already plenty of other sources of information on the subject. Yet, every tinkering knows capacitors are guilty of a lot of sins in electronics.

Clockwise from top left: Typically no energy is supplied to any exposed pins or terminals on the socket, for safety. A wall socket or outlet also known as a power point in the UK,  receptacle in the US,  general purpose outlet or GPO in Australia and New Zealand,  and less commonly plug socket  or wall plug  built into the wall of a building, connected to energized electrical wires.
Because it has holes it is known as a female connector. Sockets may also appear on portable equipment, such as portable generator , extension cords or power strips , but are still generally the half of the connection that provides the electricity. A plug also known as plug top in the UK  generally has matching pins also known blades or prongs in the US, especially if flat so it is known as a male connector , and it is connected by a mains cable power cord or physically built into a piece of electrical equipment that consumes electricity.
Some types of socket have male pins and the matching plugs have female contacts, but for safety reasons these are only used for earthing grounding in US English. Some plugs have built-in fuses for safety. To reduce the risk of users accidentally touching energized conductors and thereby experiencing electric shock , plug and socket systems often incorporate safety features in addition to the recessed contacts of the energized socket. These may include plugs with insulated sleeves, recessed sockets, socket apertures with blocking shutters, and sockets designed to accept only compatible plugs inserted in the correct orientation.
A built-in socket may be surrounded by a decorative or protective cover called a wall plate, face plate, outlet cover,  socket cover, or wall cover.
