These inventions cost ... less than 100,000 VND

From the day when the mini lamp was illuminated with fake money, Ms. Nguyen Thi Minh, a small trader selling fruits in Ban Co market, Ho Chi Minh City proved very confident with old and faded colors.

She said that the price of the counterfeit check lamp is only VND 13,000, so many people in the market find this lamp to buy. This "cheap" counterfeit money check lamp is just one of the inventions of engineer Tran Van Tin, director of ICEVN Electronic Technology Consulting Co., Ltd. - Binh Duong.

Graduated from the Polytechnic University of computers in Ukraine, he started his career as a phone repairer at . flea market in District 5 (HCMC), just because ' want to have more time to visit his mother who is in sick nearby institute '. The first inventions of Mr. Tran Van Tin are related to mobile phones.

It is a versatile battery charger , can be used for all types of mobile phones (this battery charger can also be charged directly in the motorcycle), ear protection film when using the phone . To date, home The horizontal hand invention has nearly a dozen products in hand and most have been put on the market. The " inventions " are very . very comfortable, only from 10,000-15,000 VND, a little higher than 20,000-30,000 VND, the most expensive dish is only 90,000 VND.

When asked if cheap is the company's strategy, he laughed and said: 'In the past, because I needed capital to run my business, I sold off the cell phone protection technology (a small net that prevents sound waves come into the ears, protect the ears) for a Malaysian company for $ 24,000. A great amount of money but I feel sorry and regretful, because if you want to use it, users have to pay pocket money up to 7 USD to buy. While not selling technology but continuing to produce, a membrane only costs 1 USD '.

Once there was a close friend of the same class who ran the village road, the lights were not bright enough, so they fell into a hole, suffered a brain injury and died.Going to mourning you, Tin engineers become quiet and diligent in the laboratory.

The family members saw him . going to buy an old motorbike, removing the car all day.Out of three motorbikes . light boosters for motorbike lights.Just plug the device into the headlight, the lamp will keep the original brightness without depending on the speed of the car (fast running light, slow running weak lights).The brightening kit for this lamp is priced at . VND 20,000.

After that time, there was a little capital Mr. Tin focused on studies that could bring savings to consumers. In 2005, he launched three products to save electricity, save gas in daily life, save fuel for motorcycles. This product group has received the award ' Vietnam Gold Star '. Electricity-saving compensation capacitors cost 70,000 VND, when plugged into any home power outlet, office . will save 15-20% of electricity consumption.

Tin engineers said that some places have improper wires (or too big or too small), which leads to poor electrical conductivity, in addition to inductive electrical devices (motors, air-conditioners, refrigerators . .) If there is a life expectancy, the inertia of the machine will pull the electricity consumption more often than the original designed capacity. The power compensation capacitor has the function of helping power consumption to return to real capacity.

Similarly, the ICE gas saver also features a motorcycle spark plug ignition device. The device consists of an electronic circuit with two parts: Russian anti-pulse protection circuit and microchip (1.5 kV), which helps to increase high voltage and burn excess fuel in the machine, clean carbon black soot and supap should help the engine run faster. The price of a gas-saving kit is only VND 15,000.

Compared to two sets of electricity and gasoline savings, the gas savings kit is still very new and has not had a chance to come to life, although Mr. Tin has knocked on many gas production enterprises. He argued that by looking at the gas can also be observed when the gas is out (gas cannot be turned on) and there is still gas. However, due to lack of pressure, gas cannot push out. In order to take advantage of this gas, he built equipment from pots to kitchens. When gas is low, it will not burn itself, then turn on the device. With the principle of creating pressure difference and fully automatic, the product will absorb all the gas in the tank to use.
