Figure shows a simple tester, based on an ATtiny202, a piezo buzzer, and an LED, for checking circuit wiring or tracing out the tracks on a PCB...

Let’s melt metals using the ZVS technique applied to a 1,000 W RLC resonant circuit. Have you ever wondered how intense the electromagnetic fields surrounding us can be?...

Circuit morphs the versatile 555 into a circuit that’s quite different from its usual role as an analog oscillator or timer. Here it’s combined with an NTC thermistor, and one resistors to make a resistor-programmed ON/OFF thermostat...

Texas Instruments unveiled new isolated power modules, helping enable increased power density, efficiency and safety in applications ranging from data centers to electric vehicles...

In the first part of this Design Idea, we saw how a cheap op-amp can give remarkably precise readings from an RTD. We also found that it was a false economy, owing to incurable thermal drift....

Toshiba Electronic Devices & Storage Corporation has announced the M12 Series of 3.5-inch nearline hard disk drives (HDDs) for hyperscale and cloud service providers operating large‑scale data centers...

In this second part, we’ll investigate something PWM-based, which should be more controllable and hence give better results...

This article discusses the need for precise gate voltage control and accurate gate measurements when using gallium nitride field-effect transistors (GaN FETs)...

The ovens in this two-part Design Idea can’t even warm that leftover half-slice of pizza, let alone cook dinner, but they can keep critical components at a constant temperature...

Nisshinbo Micro Devices Inc. announces the NT9000, NT9001, NT9002, and NT9003, diodes for microwave wireless power transfer (WPT)...
