Water leakage Warning

The article describes the signaling device, warning of the accumulation of water on a horizontal surface. The device is autonomous and designed to alert with a sound signal about a water leak in places closed for visual inspection. In everyday life, sometimes it becomes necessary to control the absence of water leakage from plumbing devices… Continue Reading

Power splitter

Figure 1 is a schematic diagram of the splitter, whose input can be connected to one output power source, and to the output of the splitter can simultaneously connect two devices. In addition to its main function, power splitter performs several tasks. It performs the function of the power filter, decreasing… Continue Reading

Физики создали диод для водяного тока

Физики из Гонг-Конгского Научно-Технологического Университета разработали микрофлюидное устройство, которое может пропускать через себя воду лишь в одном направлении. Оно выполняет роль диода для тока жидкости, по аналогии с классическим полупроводниковым диодом. Разработка описана в журнале Physical Review Letters, кратко оContinue Reading
