In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

A drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, the chilling outflow of energy from the device can be ...

Recently, the iGaN Laboratory led by Professor Haiding Sun at the School of Microelectronics, University of Science and ...

Schematic of the proposed all-optical RBG: (a) optical chaos, (b) optical sampler, and (c) optical quantizer. DFB, distributed feedback semiconductor laser; PC, polarization controller; VA, variable ...

The circuit was designed to create a detection scheme with reference to light energy sources. Photo Detector – a device that detects and senses light and radiant energy which uses the principle of ...

In a study that was published in Advanced Materials, Prof. Shibing Long and his colleagues from the Chinese Academy of Sciences (CAS) University of Science and Technology of China (USTC) proposed a ...
