See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

Systematic methodology is the key to quickly and effectively troubleshooting control circuits. Even the most experienced troubleshooter must rely on a systematic troubleshooting process to solve ...

Vactrols, or both an LED and a light depending resistor (LDR) in a light-tight housing, are found in analog music electronics circuits like audio compressors, voltage-controlled amplifiers (VCAs), ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

Circuit bending doesn’t get a lot of respect around some parts of the Internet we frequent, but there is certainly an artistry to it. Case in point is the most incredible circuit bending we’ve ever ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two transistors ...

Nestled inside a wound, a remote-controlled device perks up and begins releasing bacteria-killing heat, a form of thermal therapy that can fell even the most drug-resistant microbes. After it does its ...
