How do make battery eliminator?
a battery eliminator is an electronic circuit which enables the user to run a device which is normally powered by a battery, by using outlet AC power without having to replace a run down battery.
the pros for using a battery eliminator is that the device can run continously without having to replace any battery.
the cons of using a battery eliminator is that the portablity / freedom to move anywhere without trailing cumbersome wires is lost.
moreover the device should have a builtin receptacle to accept power from a battery eliminator.
most importantly the user should preferably use a manufaturer supplied eliminator , since the user then does not have to know all the technical specifications and designs requirements which are needed to make your own battery eliminator.
just for info , the following info is a must to construct a battery eliminator.
1 ) The outlet power supply voltage at the place of use & appropriate plug supply
cord for the same which will be used to connect the eliminator
2 ) The device DC operating voltage & expected current drain in operation
3 ) The appropriate jack plug which will be suitable for the device and the polarity
of the connection , since the output of the eliminator is DC.
4 ) A step down transformer of suitable rating as per points 1 & 2
5 ) Rectifier Diodes , Circuit board to mount the components , Electrolytic cap
of rating as may be required with reference to pt.2
The output of stepdown transformer is fed to the rectifier device which converts the
AC power available from the transformer to DC. A electrolytic capacitor is used to
smoothen out the variations in DC output of the rectifier & make it simulate a constant battery voltage. This description is just for info since it is impossible to give a full construction detail here suitable for any application.
How does a SIMOCODE system work?
SIMOCODE is a motor management system. It detects potential motor faults early on and allows preventive maintenance to be applied before the motor totally faults and goes off line. It is a complicated system to explain in this type of venue. Best suggestion is to look up the name on the web for a total explanation as to how the system operates.
An induction speaker is a speaker that picks up electromagnetic signals and converts them into sounds that the user can hear. An example of one that I use on a frequent basis is the tone 'n' tag kit that I use to identify unlabelled network cables at client sites. I plug the tone generator into the network port at the wall on the far end and use the induction speaker to find the appropriate cable back in the wiring closet as it picks up the signal that is being broadcast. The induction speaker device does not need to be in contact with the cable to be able to help the user find it. Once it starts to pick up the signal, it will play it through the speaker. As the probe tip gets closer to the appropriate cable, the sound the speaker plays will increase in volume. Maximum volume will, of course, indicate that the cable is located.

Why does a battery discharge itself?
chemical reactions take place in battery which reduce the charge.
it stands for Remote Keyless Entry... it means your battery in your key that you had come with your car that has the lock unlock and panic buttons on it, is running low in battery. take it to your dealership and they should replace it for you and your "RKE battery low" light will not be seen again after you get a new battery for your key...

On a standard QWERTY keyboard, the "divide" function is represented by a forward slash ( "/" ).
It usually shares the same key as the question mark ( "?" ), or can be found by itself on the number pad.
Handipoints is a website with a chore chart component and an MMORPG virtual world containing a range of online games and activities, called "HandiLand". It is developed by Handipoints Inc. The purpose of Handipoints is to "Make Fun of Work" and to provide parents with printable customizable chore charts to make chores easier and more fun. Kids check off their chores on their virtual chore chart, then they earn Handipoints and Bonus Points. It is significant because it is one of the first virtual worlds that engages children in real world play and responsibilities while marrying those activities to an online experience.
Handipoints are used to buy Savings Goals from parents---physical items in the real world. Bonus Points are used to purchase virtual items in HandiLand---the virtual world.[citation needed]
HandiLand uses cartoon cats as avatars and users walk around, chat, play Flash minigames and dress up their cat avatar characters and decorate their cat avatar character's houses.[1][broken citation]
Handipoints was launched in January 2007 [2][unreliable source?], and, after a period of beta testing, was launched officially on March 4, 2008 (2008-03-04). Free memberships are available to the site, but revenue is also raised through paid memberships.[citation needed] Memberships in the Cool Cats Club allow users to dress up their cat avatars---called Cool Cats---and decorate the homes of their cat avatars with furniture. The game is designed for children between the ages of 4 and 12 years old.[3]
basicly a website inwich your child and you can monitor their chores in a fun way. i tried it for free but my child couldn't do anything fun without me paying so... its your choice if you want to. i wouldn't recomend it though.;)fifirz
What the use of condenser in electric fan?
The Condenser or Capacitor as used with a motor in an electric fan does the job of converting the single phase AC household outlet supply to a pseudo two phase supply.
The two phases of the electrical current flowing through the motor windings create a Rotating magnetic field in the motor , which pulls the rotor along with the rotating magnetic field by attraction. This causes the motor to spin spontaneously. By implication three phase Industrial motors or fans do not need such capacitor since the rotating field is inherently generated by the three phase current and magnetic circuit.
Improvement to above:
It's correct to say that the capacitor is there for starting the motor, as the AC magnetic field is rotating too fast to generate any appreciable starting torque ("push"). Calling it a 'Pseudo Two Phase" supply obscures the fact that this is a *starting* mechanism.
Some motors leave the capacitor permanently in circuit, some (mostly older) designs use a centrifugal switch which cuts the capacitor out of circuit once the motor is spinning fast enough to accelerate without the aid of the capacitor.
Improvement to following:
Be aware that the following explanation, of the capacitor charging, then giving a "kick", is *not* correct.
On an AC circuit, the capacitor is continually charging and discharging, either 120 times (60 Hz mains) or 100 times (50 Hz mains) a second. This is much faster than the motor can come up to speed. The point is that the charging/ discharging allows current to flow in the capacitor, and it's that current in the motor's starting winding that applies the starting torque to get the motor spinning.
The description *would* be true if a charged capacitor's energy was used for starting for Direct Current machines, but these motors are self-starting anyway and need no capacitor.
The analogy with an aircraft engine is strained - it's possible to get one going by *just* pushing it over top dead centre - the fuel-air fires and the motor takes off. This cannot happen with an electric motor - they need to be doing some good numbers of RPM before they accelerate to full speed/power.
The snubbing description is correct, as is the distinction in size of capacitors and purpose.
Condenser is the old term for capacitor. In a motor circuit, there are two uses for capacitors, the first is to provide extra current to get the fan motor to overcome it's own resistance to movement, the way this works is that the capacitor charges until it can supply the requisite current, then discharges, not unlike giving an air plane motor a 'kick' before it can start proper. The other use is snubbing inductive kickback. When a inductive load, such as the coil windings on a motor, are switched off, the properties of an inductor can cause a massive power surge which can damage control circuits. to mediate this problem, small capacitors are put in parallel over the load, so that the sharp 'inductive kick' has a discharge route through the capacitor (since the 'kick' is a sharp voltage spike, it looks like a high frequency signal). If the capacitor is large, it's probably used for the former, if small, the latter.
