The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

Tommy Liu builds a vehicle-mounted particulate matter monitoring system powered from harvested wind energy and an integrated ...

A deep dive into the challenges of AI power delivery and how startup Empower Semiconductor attempts to tackle them with its Crescendo family of voltage-regulator ICs. The power demands of data centers ...

The distribution system, a key subset of the overall electric grid, provides power to residential, commercial and industrial customers. Voltage and reactive power management and control have been done ...

Maintaining energy balance is of paramount importance for metabolic health and survival. It is achieved through the coordinated regulation of neuronal circuits that control a wide range of ...

Soft robots are known for their flexibility and adaptability, but most still rely on rigid electronic components for control and timing. A recent publication from researchers at Georgia Tech ...
