In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it ...

When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...

Abstract: We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in ...

Abstract: In previous times, the task of cutting or mowing grass required a significant amount of time and exertion. The introduction of a novel breed of mowing equipment significantly facilitated the ...

Arduino library for the ENS16x digital four channel MOX gas sensors with I2C/SPI interface from ScioSense. ENS16x is a range of digital multi-gas metal oxide (MOX) sensors, specifically designed for ...

The encrypted vault backups stolen from the 2022 LastPass data breach have enabled bad actors to take advantage of weak master passwords to crack them open and drain cryptocurrency assets as recently ...
