Tsinghua 90 entrepreneurs who developed the world’s smallest PC integrated machine


the second half of 2015, the Tsinghua University Department of mechanical 90 doctoral Hua Yang, in order to solve the notebook computer size is too large, inconvenient to carry the pain point, invented a may be the world’s smallest PC machine, and a series of application about the technology of the invention patent.

Hua Yang for their invention named "torch stone", it is a mini PC machine has all functions of traditional computer, but may be small enough to hold in one hand. The design of a rectangular column, similar to the British Stonehenge Stonehenge, coupled with the light elements, so the name "Ju shi". It was time to Yang wrote a sentence – "slogan inch, crackling".


Why can

"torch stone" to do so small? The key lies in that it uses micro projection as display devices, using laser keyboard as input device. The two can greatly reduce the volume of the machine body while ensuring the actual area of the user output device and the input device. Micro projection is the core technology of DLP chip and optical path design and processing technology, which has a mature upstream suppliers in Shenzhen. The laser keyboard adopts the technology of image recognition, which can accurately identify the keyboard character of each finger, so as to realize the input function. In addition, its computing and storage schemes are implemented in a mature tablet computer, so it has excellent reliability and integration. In order to meet the needs of entertainment and office two, Hua Yang team also developed the Intel Bay Trail Z3735F X86 scheme and Windows 8.1 platform system based on Arm, and based on the scheme of rockchip RK3128 platform and customization of Android 4.1 system. After the completion of the integration, the biggest problem encountered by the team is Yang yang. Because the motherboard and micro cast power consumption and heat are larger, and the volume of the whole machine is so small, if there is no good heat dissipation program, the whole machine is not running. In the end, the Chinese team to use the latest Yang liquid heat pipe cooling technology to solve this problem.

Hua Yang "cause torch stone" from his now wife. A long time before marriage, the wife of the unit often sent her to the field trip. Each trip back home, she would complain to Yang his notebook was too big and heavy. Complaining about the number of times, Hua Yang realized that there may be some pain points. As a Tsinghua engineering male, Hua Yang has been on their own side of the existence of a variety of issues have a strong curiosity, and through technical means to solve these problems have a strong desire.

how to further reduce the volume of the notebook computer? In order to answer this question, Hua Yang began to know almost every day and Quora, read foreign books, systematically study the history of the development of computer technology, and on the rise in recent years, apple iPad, Microsoft Surface, Lenovo Yoga and > reason products appear
