2012 Mercedes Concept Coupe Style a mini CLS

MERCEDES CONCEPT COUPE







Family Class A is expanded fast. After the compact unveiled at the Geneva Motor Show, here is a low sedan or if you prefer a four-door coupe to be called CLA. Coupe concept car style gives us a true insight.





Mercedes takes care of his image on the Chinese market by reserving for two years with first because its concepts.

Last year in Shanghai, a study announced Class A Series of whose version appeared in early March in Geneva . This year in Beijing , the Style Coupe Concept foreshadows the future CLA whose production version is expected to take his first walkabout at the Paris Motor Show next October. 





At the front, the resemblance is clear Class A while the rear trunk and the modeling of the shape of the lights immediately evokes the CLS like the cabin built for four.

Signs that suggest that the surname of the production version will ... CLA Assembly on the technical platform of Class A and Class B , this sedan is 4.63 m long intercalate in the range between Class C (4.58 m) and Class E (4.87 m). But above its low roofline 1.39 m (1.45 m respectively for C and 1.47 m for the E) will make it a little sister of the CLS . 






With a 4MATIC, the concept coupe style is powered by a turbocharged four-cylinder 211 hp strong 2.0 associated with a robotized gearbox with double clutch DCT has seven reports.

But the entry-level versions of the future CLA should, in turn, rest on a front wheel drive architecture as is the case for Class A and Class B . And at the other end of the spectrum, an AMG variant of 300 hp will be entitled to 4MATIC.

George Clooney�s Electric Car Twice The Torque Of A Dodge Viper

This is George Clooney�s Electric Car Twice The Torque Of A Dodge Viper. you can pack cruise ship levels of torque into something the size of a fat person in a poncho on a Vespa. The Tango T600 is made of carbon fibre, has a 200mph SCCA/NHRA rated roll cage, has twin electric motors that produce over 1,000ft-lbs of torque, it can beat a Tesla Roadster in a 1/4 mile drag race at 120mph and it has a top speed of 130mph.

Now there are some drawbacks, it�s pretty narrow which may be good for lane splitting and aerodynamic efficiency but it�s lousy for cornering. The car is also a little bit on the pricey side at 108,000 clams, although to be fair the company is working on a new, far less expensive model called the T200.

There�s a video below of the Tango T600 beating the Tesla Roadster in a drag race and the Tango clearly wins, it�s hard to mess up a drag race in an electric car as there is no gear shifting, you just hit the gas pedal and clench. The Tango has also resoundingly beaten Shelby Cobras and Corvettes on the 1/4 mile black top. This could be the ultimate sleeper car really, it looks like a Smart Car but it can embarrass a toupee wearing Ferrari driver at the lights. Sounds like a bucket of fun.

Making a Flexible Programmable Timer Circuit

This circuit of a flexible programmable timer circuit explained in this article was designed by me in response to a request by Mr.Amit. Lets know more about the request and the circuit details.


"i need a circuit for my auquarium where it should do the following

it should switch off the lights at 10:00 pm and start at 7:00 am daily + switch off the light at 12:00 pm daily and switch up at 6:00 pm back.

this will help to make my fishes live longer. :)

Thanks in advance.

Amit desai"

So heres the circuit that I came up with. As the name suggest, the timeer is pretty flexible and may be adjusted to produce any desired time periods, according to the above requested format.

The circuit consists of four identical stages, made up of the IC 4060 timer configuration. Te timer sequence begins from the IC at the top left corner.
When power is switched ON this IC starts counting. Depending upon the setting of its pot, the IC triggers after a certain period og time interval.
This switches ON the relay and the driver transistor BC547 which consequently switches OFF the connected lamp. The stage gets latched with the help of the diode connected across its pin 3 and pin 11.
The above triggering  also switches another BC547 transistor which connects the reset pin of the next IC 4060 to ground which initiates this stage also. After a predetermined time, this IC also triggers its output at pin3 and gets latched by the corresponding diode, however this actionsends a feedback signal to the relay driver transistor, instantly switching it off and restoring power back to the lamp so that it lights up again.
Just as the above actions, the sequence further proceeds and switches ON the third IC 4060 in the line which counts the set time interval and pulls the relay back to OFF position via the diode connected to the collector of its bc547 transistor, such that the lamp again gets switched OFF.
As soon as the above triggering happens the last section at the bottom right corner switches into action and counts as per the setting of the respective pot, until the ICs output becomes high, this high reset the the first IC and switches ON the lamp once again so that the process may be restart the cycle all over again.

The pots may be increased to 3m3 for generating higher time interval periods, so is true with the respective capacitors.

 
The timer may be adjusted as per the sent request, in the following manner:

If we consider the first timing sequence to begin at 7am and end at 12pm, means the upper left timers P1 needs to be adjusted such that it activates the relay and switches off the relay after exactly 5 hours.

For keeping the lamp switched OFF in the above position and switch it ON back at 6 pm we now adjust P1 of the upper right timer section such that its output triggers after another 5 hours. This switches ON the lamp again.

The above situation needs to be kept intact until night 10pm, which is about 4 hours of period, therefore we adjust the lower right timers P1 to get it triggered after 4 hours of time interval.

Finally, for initiating the above procedure back again the next morning at 7am, P1 of the last timer at the lower right is adjusted such that it resets the first timer after 9 hours..... and the cycle repeats.

For making the circuit work according to the above specified timing pattern, after adjusting the respective hours, the unit should be powered or switched ON exactly at 7 clock in the morning....rest will automatically follow.

How to Make a Simple DC to DC Voltage Doubler Circuit Diagram Using IC 4049

The following circuit can  be used for doubling any DC source voltage (up to 15 V DC). The presented design will double any voltage between 4 to 15 V DC and will be able to operate loads at current not  more then 30 mA.
As can be seen in the diagram, this DC voltage doubler circuit employs just a single IC 4093 for achieving the proposed result.
The IC 4093 has six gates in all which are all effectively for generating the discussed voltage doubling actions.
Two of the gates out of the six are configured as an oscillator. The extreme left of the diagram shows the oscillator section.
The 100 K resistor and the 0.01 capacitor form the basic frequency determining components.
A frequency is imperatively required if a voltage stepping actions needs to be implemented, therefore here too the involvement of an oscillator becomes necessary.
These oscillation become useful for initialing the charging and discharging a set of capacitors at the output which amounts to the multiplying of the voltage across the set of capacitors in a such a way that the result becomes twice the applied supply voltage.
However the voltage from the oscillator cannot be preferably applied directly to the capacitors, rather its done through a group of gates of the IC arranged in a parallel way.
These parallel gates together produce a good buffering to the  applied frequency from the generator  gates so that the resultant frequency is stronger with respect to current and does not falter with relatively higher loads at the outputs.
But still keeping the specifications of a CMOS IC in mind the output current handling capacity cannot be expected to be larger than 40 mA.
Higher loads than this will result in the deterioration of the voltage level toward the supply level.
The output capacitor values can be increased to 100uF for getting  reasonably higher efficiency levels from the circuit.
With 12 volts as the supply input to the IC, an output of around 22 volts may be acquired.

Petrol Gas Switch For A Pajero

My current vehicle, a Pajero, was modified for dual fuel - ie, petrol and gas. However, its necessary to run the vehicle on petrol at regular intervals to stop the injectors from clogging up. This simple circuit allows the vehicle to be started using petrol and then automatically switches it to gas when the speed exceeds 45km/h and the brake pedal is pressed. Alternatively, the vehicle may be run on petrol simply by switching the existing petrol/gas switch to petrol. You can also start the vehicle on gas by pressing the brake pedal while starting the vehicle. The circuit is based on an LM324 dual op amp, with both op amps wired as comparators. It works like this: IC1a buffers the signal from the vehicles speed sensor and drives an output filter network (D1, a 560kO resistor and a 10µF capacitor) to produce a DC voltage thats proportional to the vehicles speed.

Petrol gas switch for a Pajero circuit schematic

This voltage is then applied to pin 5 of IC1b and compared with the voltage set by trimpot VR1. When pin 7 of IC1b goes high, transistor Q1 turns on. This also turns on transistor Q2 when the brake pedal is pressed (pressing the brake pedal applies +12V from the brake light circuit to Q2s emitter). And when Q2 turns on, relay 1 turns on and its contacts switch to the gas position. Trimpot VR1 must be adjusted so that IC1bs pin 7 output switches high when the desired trigger speed is reached (ie, 45km/h). In effect, the speed signal is ANDed with the brake light signal to turn on the relay. The vehicle has been running this circuit for several years now and is still running well, with no further injector cleans required.

Make a Room Air Ionizer Circuit Get a Pollution Free Environment Right In Your Home

Have you ever thought or wondered why atmosphere over hill stations and other similar places which are far away from modern cities give you a feeling of  freshness and good health? The answer is simple, the air in such places are free from pollutants and  harmful chemicals like smoke and gases. Well, if you are settled in one of those cities which is engulfed with bad air and if you have compromised with the situations, heres your chance to get rid of the situation through the circuit explained below:


An air ionizer or  as some may refer it as a room ionizer is basically a device or electronic circuit which is designed for generating voltage at the level of kilo-volts for implementing the said ionizing effects. So whats ionizing after all? The high voltage thats generated from an ionizer is actually tuned for generating a negative voltage, at around minus 4 kV. This high negative voltage is allowed to get terminated over an open ended sharp conductor tip or point thats sharply carved.
When the voltage reaches at this sharp point, it tends to continue its forward motion and gets shot or released into the air in the form of negatively charged ions.
Once in the air these ions become free to move around and start getting dispersed across the room or the premise, as more and more ions are released from the air ionizer device.

Now as these ions roam freely in the air it comes across and starts colliding with the already present pollutants like dust particles, smoke/gas particles etc in the air. As per the rules all particles and all materials present around should be positively charged, so what happens, the oppositely charged ions starts collecting these pollutants from the air by attracting them toward them (opposites attract), just as a magnet bar would do to iron pins.
The pollutants in the air slowly find themselves pulled and firmly stuck over these ions until each of the ions become so much pollutant laden and heavy that they start crashing on the ground or if they find a wall nearby they start gathering on it. In this way the air in the course of time becomes absolutely clean and free from all impurities.

The circuit is quite simple and can be built even by a layman, having just basic knowledge of electronics.

The circuit is fundamentally based on Cockroft-Walton Ladder Network, The concept makes use of a network of many diodes and capacitors arranged in such a way that the applied voltage to it gradually becomes stepped up to very high levels, in the order of around 10kV,

However a 10kV range is not suitable for the discussed ionizing effects, in fact at this level the effect might produce opposite results.

If we go by calculations the present design would also generate around -10kV, spoiling the intended cause, however practically it is found to be dropping to about -4kV. This reduction happens due to radiation losses, because in the course of its stepping up, the voltage tends to spark through emissions across the PCB until finally the resultant voltage at the output tip of the device reaches only up to around -4kV which is by Gods grace the exact level for achieving the ionizing effect.




The entire circuit may be built over a general purpose board, by soldering the shown number of capacitors and diodes exactly in the way they are arranged in the diagram. Following the diagram pattern would make the making easier to assemble and would produce guaranteed results without faults.

After the circuit is assembled, check the entire board for any wring connections, this is important because the circuit is very critical with its polarities, a single wrongly connected diode would make the results zero.

After proper confirmation, the soldered side should be thoroughly cleaned with thinner so that no residual flux stays deposited causing loss of voltage and reduction in the desired effects.

The end which is terminated for releasing the ions must be needle shaped, preferably a small pin or needle can be used there for enabling perfect prorogation of the ions.

After all the above precautions are complete, its time to power the unit. Be extremely careful, as the entire circuit is connected directly with mains AC and can be life threatening if touched in the powered position.

Once the circuit and if hopefully everything is rightly done with the assembly, you would hear a "hissing" noise near the tip of the releasing pin point. The area near the tip of the pin would give you a cooler sensation like a cool breeze flowing out.
The point would also produce a fish like smell.....all the above indications would confirm that the unit is working right and you are already breathing fresh air around your nose and heading toward a healthy life.

THE ABOVE CIRCUIT WAS SUCCESSFULLY BUILT AND TESTED BY ONE OF THE KEEN FOLLOWERS OF THIS BLOG, MR. ALI ADNAN.
THE FOLLOWING BEAUTIFUL PICTURES WERE SENT BY HIM, LETS ENJOY THEM.

Watch A Furious 7 Extended Trailer

The seventh movie in the Fast & Furious franchise will be in theatres Friday, April 3, 2015. You love cars, you cheer for special effects, you dont care about good writing, you tolerate mediocre acting, and you will therefore see it at some point. 

Vin Diesel, Dwayne Johnson, and Jason Statham all in one movie? With the late Paul Walker supporting? It wont win an Oscar, but Furious 7 is set to be at least as crazy as its predecessors. Which is what its supposed to be. 

This new extended trailer appeared during USA Networks premiere of Dig this evening. When you watch Dig, examine it closely for automaker tie-ins. USAs White Collar loved Ford mentions before an out-of-the-blue switch to constant BMW 6-Series adulation. Suits has been known to show plenty of Lexus close-ups. Neither GCBC nor any human on the planet has any idea whether those moments caused buyers to head to their nearest Ford, BMW, or Lexus dealers.
