[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 ...

There are two separate circuits when it comes to motors and motor control. The main power circuit is what supplies the power ...

Courtesy of www.MikeHolt.com. Based on the 2020 NEC. Class 2 circuits are limited to voltage and current values that don’t (usually) present a shock or fire hazard. The power supply for a Class 2 ...

The control circuit in Figure 1a allows you to manually adjust the power delivered to a load. By changing the setting of potentiometer R 3, you change the phase angle at which the thyristor (Q 3) ...

In many industrial and commercial situations, there is often a need to energize or de-energize equipment that is remotely located or select one of two modes of operation for the equipment. This can be ...

Advances in methods that allow targeted remote control of neuronal activity open new possibilities for investigating and manipulating the function of neuronal circuits in vivo. The group of Michael ...

E-T-A Circuit Breakers has introduced the E-T-A 4930, a new remotely controlled, single pole circuit breaker (RCCB) approved to MIL-PRF-83383 for the protection of aircraft electrical systems and ...

The diagram above is a typical PCB layout in Altium Circuitmaker software. The days of “electro” and “mechanical” being separate disciplines are long gone. Virtually all mechanical systems now come ...
