In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

Synthetic gene circuits are designed to implement novel biologic function, including cellular logic, dynamics and complex cellular and multicellular behaviours. A decade after emerging as a discipline ...

Invigorating the idea of computers based on fluids instead of silicon, researchers at the National Institute of Standards and Technology (NIST) have shown how computational logic operations could be ...

A scientific team has managed to stack 41 layers of semiconductors, multiplying the density of the circuits by six, without ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

An engineer has assembled the most complex logic circuit yet assembled in a single bacterium. The logic circuit, in which genes and the molecules that turn the genes on or off function as logic gates, ...

Saleae logic analyzers seem to have it all: good sampling rates, convenient protocol decoding, and plenty of channels – but not a good way to set rising or falling-edge triggering. [James] found this ...

Simple Sound Processor presented here is an ultra-simple circuit module suitable for almost all basic electronics and microcontroller projects. For example, this module can be used as a front-end in ...

The circuit presented here (see figure) provides users with an indication of a high or low logic state. When the input is a logic 1 (high), the common-cathode display indicates "H." When the input is ...
