For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

Helium leaks are hard to detect. Helium is odorless, colorless, tasteless, and does not react with other chemical substances.

Researchers describe an acoustic meta-surface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation.

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...

Wireless power transfer (WPT) enables device charging without direct physical or wired connections. Resonant circuits are key components of WPT systems that optimize energy transfer from the ...

Something that probably unites many Hackaday readers is an idle pursuit of browsing AliExpress for new pieces of tech. Perhaps it’s something akin to social media doomscrolling without the induced ...
