A Circuit: Here is a circuit that can be used to control switchable electronic devices. Add some long leads to the PhotOResistor (CdS cell) and mount it pointed at your computer monitor. Use black card or a film cannister to control ambient light falling on the sensor. If you use this circuit to launch a model rocket, you must have a manual switching system built into the circuit and follow all model rocket flying safety procedure.......

This is the high current dc power supply circuit with 5V output. The high current regulator utilizes an extra winding or a separate transformer to deliver power for the LM317 regulator so that the pass transistors can run closer to saturation and increase performance. For excellent performance the voltage at the collectors of the two parallel 2N3055 pass transistors ought to be near.......

La sonda lógica es un instrumento de suma utilidad cuando hay que analizar circuitos digitales. Como la mayoría de vosotros ya sabéis, los circuitos digitales solo trabajan con dos estados o niveles de tensión. Si hablamos de lógica TTL(lógica transistor-transistor) la tensión booleana para el 1 lógico e.......

Hi, I m back after about 6 -7 months hiatus. Honestly, i was so busy back then due to my final year course here. The exam result will be coming out within a week and I will graduate a month later before returning to my homecountry. As exam is over and I m now a free, jobless and unemployed in this summer holiday I manage to find some time to return to my delayed project, the FM receiver circuit. My last post discussed about my generalised FM receiver circuit from lengthy hours of internet resear.......

Este es un circuito de mucha utilidad para mi ya que muchas veces tengo que contar frecuencia o medir una señal que tiene un nivel de tensión muy bajo (en el orden de los mV) y se hace imposible medirlo con algunos instrumentos como frecuencímetro con microcontrolador donde el gpio soporta niveles TTL o bien en algunos multímetros que cuentan con frecuencímetro integrado tendremos el mismo problema ya que no suelen tener una sensibilidad muy buena.Este circuito es un simple amplificador e.......

Here's a power-on time delay relay circuit that takes advantage of the emitter/base breakdown voltage of an ordinary bi-polar transistor. The reverse connected emitter/base junction of a 2N3904 transistor is used as an 8 volt zener diode which creates a higher turn-on voltage for the Darlington connected transistor pair........
