Timbre electrónico con CD4017Timbre electrónico con CD4017

El oscilador de relajación tiene una frecuencia que depende de los valores de C2 y R14 más el valor del potenciómetro correspondiente conectado a cada una de las salidas del CD4017 El timbre electrónico genera nueve notas, totalmente manipulables con los 9 potenciómetros que varian la frecuencia a la que oscila el UJT. El multivibrador astable enviará su señal de salida a la entrada de reloj del contador de décadas (patita 14). La entrada del reloj de CD4017 estará habilitada siempre y .......

High voltage experiments: Part 2- Homemade flyback transformer.

As i ve said before, in this second part i will show you my high voltage experiment using my own hand-wound homemade flyback transformer using the ferrite core from the original flyback transformer salvaged from old cathode ray tube (CRT) television monitor. Before I move on, here are the photos taken and descriptions:The overall setup. I ve changed the power supply fro.......

Matriz 8x8 con motivo de Navidad

Hola, hoy estaré realizando una actualización a la matriz de led 8x8 que posiblemente ya conozcan de mis otros post https://electgpl.blogspot.com.ar/2013/11/matriz-8x8-mensaje-con-desplazamiento. htmlEn este caso, no hay nada nuevo, solo he agregado unas secuencias de animación, texto scroll y dibujos estáticos. La idea era montarla en el árbol navideño junto a unas tiras de led RGB para hacer una navidad mas tecnológica. Me queda como pendiente (aunque no tengo demasiado tiempo para ello.......

Circuit- -DC CURRENT INDICATOR #4

The circuit below uses some common components to turn on an LED whenever DC current above a certain level is detected.  The circuit uses a very popular LM393 dual voltage comparator from National Semiconductor and a common 1N4148 signal diode.  The diode acts as a crude 0.7v voltage reference.  Only one of the comparators inside the 8 pin package is ..........
