[2 April 2023] So I was researching into input devices, and I had an idea: what if there was a way to use the SpaceExplorer I have in a shelf as a 2D mouse? Hear me out here! The main reason it was in a shelf was because I didn't want...
A very old project. By using a single VU meter IC (LM3915?) and aanother IC that sequentially connects the columns of LEDs to ground (i.e.the time scale), the VU meter effectively "sweeps" across the waveform ina quick succession.

Arduino Uno is an open-source microcontroller board based on the ATmega328P microcontroller and developed by Arduino.cc. It is the first board designed by the Arduino.cc team. The board is equipped with sets of digital and analog input/output (I/O) pins...
In the age of energy-efficient devices, the poor efficiency rating of a power supply can be a deal-breaker. The solution that you finally choose depends on your requirements for efficiency, cabinet space, output regulation, transient response time, and...
I have been interested in smart home systems, automation, and sensors for a long time. I like devices without reference to any manufacturer. So I often use the excellent Shelly Wi-Fi devices. These relays, controllers, and bulbs have an open embedded...
Choosing the right motor for a CNC mill, lathe or router depends on several factors, including the requirements of the project and the characteristics of the motor. Here are some important factors to consider when choosing a motor for a CNC machine:...
1. What is an Arduino? Arduino is an open-source hardware and software platform that is used to build and program electronic devices. It consists of a microcontroller, which is a small computer that can be programmed to control different components...
The main component of the analog front is an instrumentation amplifier. An instrumentation amplifier is a closed-loop gain block that has a differential input and an output that is single-ended with respect to a reference terminal. Most commonly, the...
The term SMPS is often heard and you might have also seen it being used in different applications like computers, mobiles, battery chargers, vehicles, etc. But what does the term SMPS mean, what is its working and why is it being used very often in various...
