Circuito Grabador de Audio APR9600

Hola, APlus diseño un circuito que es capaz de grabar y reproducir audio por 60 segundos en un solo chip y para hacerlo funcionar solo hace falta unos cuantos componentes como resistencias capacitores y por supuesto un micrófono, La calidad del audio y la duración de este depende de la resistencia "OscR" la cual le va a decir al chip de que calidad se debe guardar el audio.

Para una grabación de 60 segundos se necesita de una resistencia "OscR" de 84K Ohms, para una grabación de 40 segundos se necesita una resistencia de 38 KOhms y para una grabación de 32 segundos se necesita una resistencia de 24 KOhms, por supuesto que para estas resistencias deberemos comprar valores comerciales por ejemplo para una grabación de 40 segundos pondremos una resistencia de 39 KOhms.



Un pequeño inconveniente de este circuito es que el audio que es capaz de emitir es de un volumen muy bajo por lo que es recomendable hacer un pequeño amplificador de audio, yo recomiendo el LM386 ya que esta al alcance de todos y ademas muy sencillo de usar.



Bueno y realmente es sencillo de armar, a mi me ha quedado así :P.

Low-Side MOSFET Drive Circuits and Techniques - 7 Practical Circuits

Image
In many circuits, it is necessary to use MOSFETs for switching. In many cases, the MOSFET drive signals are generated by microcontrollers. In other cases, they are generated by ICs – PWM controllers, timers or any IC in fact. However, MOSFETs cannot always just be connected to the drive signal and be expected to work properly. Due to the construction of the MOSFET, driving it is not the simplest of tasks, especially for beginners. There are many users who regularly ask for help on MOSFET drive related issues or problems on different blogs, websites and forums. So, here I will show some MOSFET drive techniques/methods for MOSFETs configured as low-side switches. Before I head on to MOSFET drive, let me just tell you what a low-side switch is, in case you don't know. When the MOSFET (that you're using as a switch) sinks current, it is a low-side switch. The load will be between the drain and +V supply. The source will be connected to ground. Gate will be driven with respect to gr

Using the SG3525 PWM Controller - Explanation and Example: Circuit Diagram / Schematic of Push-Pull Converter

Image
PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a

Simple MW Transmitter Circuit Diagram

Image
Today I'm going to give you a simple MW Transmitter.This transmitter can be operated with 9 v power supply.Here we have used common transistor BF494B.Here we have used MW antenna coil you can use the 8 ohm speaker to speak that means here the speaker does the work of the mic.To get the maximum result build this on a pcb and don't supply power without connecting the antenna.             Note:   Don't missuse this circuit            you can send signals up to 500M
