When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

The circuit has been designed for the purpose of creating a portable unit of preamplifier that would function as standalone control for gutitars. TL062 – a low power JFET dual operational amplifier ...

This bass and treble controller circuit is based on the classic Baxandall tone control circuitry and provides a maximum cut and boost of around 10dB at 10kHz and 50Hz. The first stage that is built ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

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 ...

Early radio receivers and record players nearly always had a knob marked “tone,” which was usually a crude low-pass filter with some form of severity adjustment. At best, these controls could ...

[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 ...

Figure 1: A population-control circuit programmes population dynamics by broadcasting, sensing and regulating the cell density using cell–cell communication and negative feedback. Figure 2: ...
