With the clock ticking on Circuit City Stores Inc., three bidders are circling the company, though liquidation of the nation's second largest consumer-electronics chain by sales remains the likely ...

The instinctive reaction when measuring nuclear radiation is to think of a Geiger counter, as the low-pressure gas tube detectors have entered our popular culture through the Cold War. A G-M tube i… ...

This electronic lie detector circuit project will give two readings: one for difficult questions for the subject and another to show its emotional state in general. The emotional states are detected ...

The circuit can run off a standard 12-V battery, but the IC’s operating voltage should not exceed 16 V or the oscillator will give a false alarm for a high-voltage failure. The circuit’s ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their ...

In ring oscillator-based PLLs, the VCO is typically implemented using a ring oscillator with a class-C configuration. To improve stability, an Amplitude Adjustment Circuit (AAC) is used to stabilize ...

Circuit sculpture has formed the basis for several stunning clock projects: this Tie Fighter-shaped clock for instance, or this insanely complex LED clock. Our 2020 Circuit Sculpture contest ...

Amazon’s $29.99 Echo Wall Clock is now here to complete the set of minimalist Alexa devices (including a smart microwave and outlet plug) that the company announced earlier this year. Like some ...

This is not an infrared motion detector! The IR detector circuit in principle, converts the IR signal pulse trains into noticeable aural notes. S1 is used to switch on/off mains power and LED1 ...
