Whether they’re for sensors in artificial skin that demands flexibility or for wearable electronics where the circuits must withstand our sweat, silicon-based chips aren’t always up to the t... Read more
In this project we are going to make a Buck Converter Circuit using Arduino and N-Channel MOSFET with a maximum current capacity of 6 amps. We are going to step down 12v DC to any value betw... Read more
Ammeter is used to measure current flow through any load or device. Here in this Arduino Ammeter, we will explain about measuring of current by using ohm’s law. It will be quite interesting... Read more
For applications such as motor control or power supplies, it’s often necessary to know whether the ac line is at 120 V or 220 V to adjust the operation. The circuit illustrated in the figure... Read more
Due to many requests for the PCBs I do currently have some PCB Sets and prebuilt kits in stock. Take a look here: https://malectrics.eu An Arduino Nano based Spot Welder for battery welding... Read more
Seismic activity or “Vibrations of the earth” is measured using ProtoCentral’s OpenPressure 24-bit DAQ System. Introduction A geophone is a magnetic device used to measure... Read more
Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting... Read more
Voltage references are a humble piece of hardware, their sole function is to provide a stable, known voltage. This constant, known value of voltage can then be used as a reference for ADCs a... Read more
With summer arriving, and the fear of dried out chicken looming, we wanted a more high tech way to track the temperature of items we are grilling outside. There are wireless probe thermomete... Read more
Three major power supply (Figure 1) architectures are defined for any engineer: 1.Linear Regulators. 2.Pulse width modulated switching (PWM). 3.High resonant technology switching. Some impor... Read more
This Design Idea gives two versions of an indicator light that changes from green to red as a battery discharges. There are many circuits that do this sort of thing, but all the ones I have... Read more
