The post comprehensively explains a simple electric match igniter circuit which can used for implementing a foolproof ignition of a series of Ematches through a microcontroller based control system. The idea was requested and explained by Mr. Jerry ShallisThe details may be understood by reading the following email discussion between Mr. Jerry and me. Hi Swagatam, I've just been looking at all the useful stuff on your site, and I'd start by thanking you for putting it all in the public domain. I.......

Au Group Electronics Author: Chaonan Chen, Huihui Duan, Au Group ElectronicsThis application note uses a dsPIC33FJ64GP802 (28-pin SOIC SMD package) demonstrating step by step operation on how to use Au Group Electronics "3-in-1 mini-Lab" and "BB0703 programmer" to burn program/code into a dsPIC33F microcontroller. (Note: Experiences found that the VDD level on BB0703 (PICkit 2) is very critical for programming dsPIC33F family microcontrollers, without set it correctly might result in program/era.......

Arduino is very popular and easy to use. With Arduino, we can do lot's of projects and experiment. So today we add one more projects in our Arduino project list. In this article, we are going to make a digital voltmeter.using an Arduino board.In this project, we measure the input voltage range between 0 to 50V by using the voltage divider. It is very simple to use Arduino as a voltmeter. Arduino UNO has  5 analog pin to read the input analog value. If we have an idea about reference voltage th.......

This circuit is also found in DC Magazine. The circuit that I came up with is shown below.  It uses 5 identical circuits.  Each one is wired in parallel with it assigned 650F super capacitor.  A LM385 provides a 1.2v voltage reference.  A resistor divider measures the voltage across the capacitor and feeds the voltage to a low power, low voltage op Amp..........

This resistance meter can measure resistances up to 200 mega-ohms. The value of the resistance is indicated on a linear meter scale (0-100 uA). The operation of the circuit is based on sensing the voltage drop across a reference resistor. The voltage sensing IC used here is a CMOS NAND gate (CD4011) whose high impedance [ ... ].......

Measure up to 128 strain gauges, balanced bridges like pressure transducers or voltages over USB. When a bridge input is selected the Windmill Software automatically monitors excitation voltage and performs the bridge calculation to produce a reading in microstrain. This eliminates errors due to changes in excitation voltage. You can also set a zero reference level and monitor changes relative to that level........
