When the thermistor temperature is below a set value the voltage at pin 2 of the 555 drops below 1/3 of Vcc. This turns on the triac controlled heater and also starts the timing cycle. If the ...

Because the wiring and the inputs and outputs (I/Os) are the most vulnerable elements in a system, be sure to locate and identify these elements in the problem circuit. Sometimes, the only way to test ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

The function of this automatic volume control circuit is to amplify signals without distorting its dynamic compression. The amplitude differences in the signal are levelled off and the disturbing ...

Short circuit current ratings should not be overlooked during panel design. Negative impacts can occur to production, equipment and, worst case, plant personnel. Per 2014 NEC Article 100, short ...

GameSpot may get a commission from retail offers. Mad Catz has a new controller on the market that promises to marry customization with solid construction in a package suitable for competition on a ...

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: ...

CES 2012 may have been dominated by OLED and progressively "Smart"er TVs, but there's one product that caught our eye that wasn't quite as big an announcement, but as tasty nonetheless; gaming ...
