The Best Smell and Noise I ever had


People hate noise, people hate unpleasant smell. Well, I hate engine noise and its exhaust cause i had a damn problem tuning and starting my LPG engine.

Me and my friend tune and crank the engine for few days and it seems about to start but loses momentum a few a couple of cycles.

At last, Prof came into play. He diagnose step by step, testing parameters, finding out the possible problem and uses some tricks and voila. Engine starts really easy and operating strong. I like the strength of combustion.

Get more tuning, massage the engine out and let it run lean.

你的温柔,我的知足


骑着脚车,迎面微风,感觉好温柔。
天的温柔,地的温柔,像你牵我手。
然后知道,你将离开,突然很寂寞。
思念你,带给我温柔。

不知道,不明瞭,不想要,为什么我的心,
明明是想靠近,却不敢越过境。
不知道,不明瞭,不想要,为什么我的心,
徘徊在灰色区,在对面墙等你。
还是把我最纯的爱给你。

不知不觉,不情不愿,又到转弯口。
你望着我,我对你笑,此刻好温柔。
没有理由,没有借口,我这样对你说。
看你笑,已让我知足。

想要去拥有一道彩虹,
想再得到雨天后的风,
天上的星星叫地上的我,
凡事要珍惜,要会知道足够。

如果我爱上你的笑容,
要怎么收藏,要怎么拥有。
如果你快乐不是为我,
会不会放手,其实才是拥有。

那晚你和我,那通电话,
那样的唱着那一首的歌。
那样的回忆,那么足够,
足够我天天都品尝着寂寞。

那晚你和我,骑着脚车,
那样的看着那一片星空。
那样的回忆,那么足够,
足够我天天都品尝着孤独。

当一阵风吹来,蒲公英飘随风,
只希望有个人,记得他,祝福他。
最终他身影消失在人海尽头,
才发现,这回忆,最空。

如果我爱上你的眼神,
要怎么收藏,要怎么拥有。
如果你快乐是因为我,
那儿的心灵已感到感动。

知足的快乐叫我活得幸福。

Impressive Electronics


I was doing EFI for my engine. We ve got a inverted signals from engine which make the ECU confused about injection timing. So i need to condition the signal.

Was figuring how to condition a signal generated from magnetic flux, it has a deep valley which is favorable if it is positive.

First we were filtering, trying to cut off the deep valley and make full use about the peaks, but it has two small peaks which is also confusing. We even thought of putting a heavy capacitor to cover off the smaller latter peak.

Thinking from digital aspect, invert it with an Op Amp, then make a square wave using Schmit Trigger. It could be working. However, my prof finally came and come out with another brilliant idea.

We use AC coupling and trigger the transistor switch inversely and thats it, simple, for widely available components with just capacitor, resistors and transistor plus a POT. We made a nice fat signal and it is also squared. What a wonderful analog conditioning.

Platonic Love


I read from somewhere about Life. Life is about seeking love. You should find these 4 people in your life. 1, yourself. 2, person that you love. 3, Person that loves you and 4, person that you can live long with.

Loving a friend is one of the best things i have done in my life. A platonic friendship starts through communication. After communication, you have understandings.

If you love an opposite sex friend, you are much easily trapped in a grey zone. White zone is lover's zone and black zone is just-a-friend zone. If you are in grey zone, probably you either ends up in sky high cloud nine or sorrow despair. You can choose to be in which situation.

The friend that you love is probably very attractive to you. That friend will be attract other people as well like she attracts you. Bias as every human is, you always wanted her to be with you all the time, and thinking about you. In reality, it couldn't happened that ideally. People used to have choices in life and making decisions. You can't restrain your love one making other choices. By the way, that's is not love already.

If you want this happened in the ideal way, you will end up in sorrow despair but if you let go, loving her from distance, provide her the best support in suitable condition and only hoping you are the winner at last. If she reacts what you expect, then you are in cloud nine.

Loving is not about having her all the time sticking to you. Give her freedom, give her chances and respect what she thinks is right and what she decides. She will find a place where she belongs. Even though it may not be your shoulder but loving people is giving blessings to others and these blessing will serve you well next time.

Ironically, the one you love, the one that loves you and the one you live long with are not the same person. Treat that naturally, express your sincere feel, love if you able to and believe in fate that makes life interesting with surprises.

In the end, it will be the greatest pleasure to let the one that you love know that you love her and she returns her love to you.

Bloom Energy-Be the Solution


Bloom energy figures out the solution-solid oxide fuel cell. Its founder, KR Sirdhar was a NASA engineer. He uses this fuel cell to create oxygen and water in Mars mission to make Mars a second home. Then he thought back, instead of finding a new home why not make my first home a better place to stay? Thinking back and he reversed this technology. Lets add hydrogen and oxygen to produce electricity.

Solid Oxide Fuel Cell is nothing revolutionizing, the core technology is the sand like ceramics as the electrolyte sandwiched by a coated anode and cathode. No precious metal in used like other types of fuel cell. Air goes into cathode and stream mixed with fuel to form reformed fuel at the anode side. Chemical reactions begins after the reformed fuel crosses the anode and attracted the oxygen ions. This reaction generates electricity, water, heat and small amount of CO2. Electricity is what we want, heat is needed for fuel cell and water is required to reform the fuel.

After 8 years of researching and optimizing the products, it is finally been revealed to the world in high profile. They are been introduced not as a fresh product, they came out with the claims of Big companies like Googles, Ebay, Coca-cola, Fedex as their client. This is even more persuading as business leaders who taking the responsibility of profiting from business and concerning environmental problems are taking Bloom Energy's solution-the Bloom Energy Server.

Being an engineer, he/she has to possess sound technical knowledge and also good in doing business. KR Sirdhar is a live example. He knows about the value proposition of his product.

First, it is cost effective. For big companies, its payback period is 3-5 years and it is fixed power price for over 10 years. So you pay for this bloom box, and your investment is being paid back in 3 years later and at the same time you are enjoying the fixed power price for 10 years without worrying the fluctuation of the price which more likely to be increased as time goes on.

Second, fuel flexibility. Any hydrogen fuel will do from biogas like ethanol. biodiesel to fossil fuel, like LPG, CNG to renewable energy like sun power, wind power etc. Hence, the owner can choose which type of fuel in their region which is the cheapest accordingly. This is the flexibility that matters a lot in value proposition.

Third, high efficiency. As you have Bloom Box/ Bloom Energy Server. You do not need a grid, or the fuel infrastructure. This increase the efficiency of power transmission compared to centralized power distribution system. It claims to have twice the efficiency of the current grid system. What's goes out is twice the efficient, halved the fuel consumption. If you are using renewable fuel, you are in carbon neutral. You can use the electricity without feeling guilty of polluting the environment.

Fourth, reliable. You can have electricity when sun isn't shining and wind doesn't blow. It is base load and work 24/7,365.

This is indeed a cost effective, reliable, better use of fuel and high efficiency product that guarantee will change your life in near future.

Solution for the Future

In foreseeable future, the world is looking for a solution. A solution for everybody in this world. What's the problem of everyone in this world?

US and Europeans are now going green as they have developed as much as they have polluted. They develop wind power turbines, solar panels but they are not reliable enough, they have power grids but its not that efficient.

China and India are developing fast and aggressive. New mega-cities sprout like mushrooms after rain, Latin America also keep their pace to improve living qualities. They elder generations wants their younger generation to live better, wealthier and so most of the developments emphasize in wealth creation.

Economic growth is strongly linked with energy consumptions. When you move up from middle-class, you will want to consume more energy by purchasing better automobiles, more energy consuming household like TVs, electrical appliances etc.

We cant stop people to grow economically and hence we will be focusing on generating cleaner energy to support economic growth of human population and conserving the nature at the same time.

What's the solution? Coming up next...
