Voltmeter

A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter.

Portable Power Supply (18650 Battery)

“Every time, when you get a new idea and need to design a new electrical circuit, you want to test your idea as quickly as possible. The breadboard very helpful to us in such cases. There comes a moment when …

Portable Rechargeable Power Supply

“A 3V to 20V portable rechargeable power supply from off-the-shelf components. Powered by a single 18650 battery. There are a number of Portable Power Supplies that makers have built around the cheap J5019 Adjustable Step Up module. Here are just …

Autonomous Arduino Mega Track Robot

“This robot uses 4 Sharp IR sensors to wander around the house and avoid running into things. I was looking for a fun weekend project with parts I had around the house. In digging through my junk box, I found …

Reuse Old Mobile Phone Batteries

“Reuse old mobile phone batteries. I have been using used phone batteries in a bunch of projects recently after discovering an awesome little module on eBay. The module comes with a Li-ion charger and also a voltage regulator, allowing you …

Ultimate Electronics Helper || Variable Bench Top PSU With Helping Hands

“When working with electronics two tools are pretty much always needed. Today we’ll be creating these two essentials. And we’ll also take it one step further and merge these two together into the ultimate electronics helper! I’m …

Simple Digital Voltmeter Circuit With PCB Using ICL7107

“In this project we have a tendency to design a circuit to build an electronic voltmeter while not making use of any microcontroller. Here we have a tendency to employing a very moderate IC for voltage activity particularly ICL7107/CS7107 …

Talking Multimeter

“The talking multimeter uses the PIC32MX250F128B as a voltmeter, ohmeter, and capacitance meter that speaks the reading as it is measured. Spoken measurements improve the usability of measurement devices since the user will be able to focus on the circuit …

Home made 30 volts Panel Volt Meter Using PIC MCU

“Everyone knows that PIC microcontrollers are still very popular due to its cheap price, user friendly, simple package, and its uncounted applications. One of the major application of PIC16F676 is its internal 10-bit ADC(analog to digital converter), this option …

Project  PSU Burner

PSU Burner

“What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power …
