Simple Solar Charger Circuit Diagram

Image
I suppose this circuit is a very useful circuit diagram for you all.Because this circuit shows how to connect a Solar panel with a circuit and a battery.You have to use a battery according to the power of the solar panel.here I have used 1N5817 diode to protect the panel and to control the power of the circuit diagram.Keep it in your memory If the two connections of the solar panel touched together it will damage your panel. Note   # Don't connect your panel to the circuit with out diodes   # Build this circuit on a PCB

Simple Tracker circuit Diagram

Image
Most of the guys asked about tracking circuits so today I'm going to give you a tracking circuit diagram.The special thing of this circuit is you can get the signals of this circuit through a normal radio.This circuit can signals 200M to 400M.According to the environment distance can be changed.And another special thing is you can operate this tracker circuit with 3V power.Here I have used BC557 and BC 547 transistors.   Note: # Build this circuit on a PCB  # Don't supply over 3V  # Use H antenna to receive signals

Este tipo de motores, son muy utilizados para alcanzar altas velocidades y de bajo desperdicio de energĂ­a, ya que como su nombre lo dice, no tiene cerdas,  en estos motores debe ser proporcionada tres señales, idealmente tres señales senoidales desfasadas entre si 60 grados la una de la otra. En busca de una fĂ¡cil incorporaciĂ³n me encuentro realizando un circuito orientado a una electronica digital que permita la manipulaciĂ³n de velocidad de este por medio de señales digitales, como he venido haciendo en este blog pretendo que el cerebro sea un Arduino ya que ayudara mĂ¡s a personas menos relacionadas con la electronica y simplificara la forma de entender como funciona el dispositivo en general sin la necesidad de detallar. Tras generar las señales debe mantenerse sincronĂ­a con el motor para realizar cambios de velocidad, ya se que se quiera acelerar o desacelerar el motor de una manera estable, para esto se requiere analizar el campo electronomagnetico de reversa que se puede leer en l

Hacking the PIC32 Comparator Reference to obtain a DAC

Image
The PIC32MX250F128B has a myriad of peripheral features that makes this cheap little 28-pin 32-bit microcontroller extremely powerful. However, it does lack a digital-to-analog converter (DAC). A simple approach to digital-to-analog conversion is to use one of the PWM channels and then to use an RC low-pass filter at the output. However, there is another neat little feature of the device that can be exploited or rather utilized to obtain a rather crude DAC – the analog comparator module. Rather, the analog comparator reference module. The PIC32MX250F128B contains an internal voltage reference module that was created to be used as a reference voltage for the internal analog comparator module. However, it does allow you to output this reference voltage to an output pin. Analog voltage output with digital control? Sounds like a DAC. The voltage reference module is built off of a 16-tap resistor ladder network with two selectable ranges – from 0 to 0.67 CVREF or from 0.25 to 0.75 CVREF. CV
