1 Introduction Open-source development microcontrolled electronic boards like Arduino and Raspberry Pi are gaining popularity in the Research and Development field due to their versatility and ease of use across various applications. This paragraph focuses on one specific application, namely the potentiostat, which holds significant importance in the field of electrochemistry. The potentiostat is a
An impedance-meter evaluation guide: identify the real converter, require documented timing and calibration, and separate phase processing from accuracy.

The problem we picked was – Growing plants in limited space by amateurs. Many people would like to grow plants (basic vegetables, herbs for the kitchen, etc) but do not have enough space in their house to do so. They also may not have the expertise to grow plants, so would need an easy DIY

The beginning of the project came from an idea, an inspiration from a video posted on the Internet on the YouTube channel “I like to do things” … Then came the need to make a stand for one of my monitors that housed a clock, a digital analog converter – DAC – integrated into an

Dire situations require unpleasant solutions, an excellent example of this statement is spying and we have seen what the NSA has done in this regard. It goes against proper ethical character, however, it might be needed in certain circumstances. Usually, the first thing a person who wants to spy would do would be to check

This project is without doubt the most complex I have undertaken, with sixteen IV-11 VFD tubes, two Arduino Mega cards, ten LED Neon light circuits, a servo, an electromagnet, two MAX6921AWI IC Chips, five DC power supplies, a HV power supply, two DC Volt meters, a DC Amp meter, FM stereo radio, 3W power amplifier,

Measuring muscle activation via electric potential, referred to as electromyography (EMG) , has traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems. Yet, EMG

In most cases first project in electronics for beginners is building simple audio amplifier. That is because it requires small number of elements and not a lot of knowledge to build one. For low power amplifiers we could use integrated circuits like TDA family. But I will show how to make amplifier using operational amplifier.

I built this a short while ago as an idea to use in a primary classroom setting. Poster displays are often used by primary teachers wanting to control the noise levels in their classrooms but I wanted to add technology to make it dynamic and responsive. The motivation for this came after seeing the Adafruit

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I
