“In this project I will show you how I used a Raspberry Pi Zero, NiMH batteries, a homemade over-discharge protection circuit, a rearview lcd and an audio amp to create a handheld game console that can play retro games. Let …
“Around this time last year I published an Instructable just like this one where I used an Arduino Uno with the Si4703 evaluation board, a logic level converter and a 5V LCD to make an FM radio for my jukebox …
“It’s Time to Make Some nice amplifier which has nice audio quality with very low distortion and simple and quite easy to make because a circuit is very simple & very few components are required and all the pieces of …
“You can buy remote Oregon sensor THGN123N for about $20 or you can built your own temperature/humidity wireless sensor that implements Oregon protocol V2.1 for about $9 and have fun! First of all, we need accurate temperature/humidity …
“The humble Arduino can do a lot of things, but did you know it can emulate a USB keyboard? You can combine those difficult to remember long keyboard shortcuts into a single custom shortcut key, with this simple circuit. “
“It seems, that the main problem with microcontrollers for fan of electronics (especially beginners) is to find out where to apply them :) Nowaday electronics, especially digital one, is more and more looks like a black magic. Only 80-Lvl wisards are …
“Code for a spectrum analyzer. The code is to be ported to an ATTiny85 to make a project. Uses Goertzel’s algorithm with a Hamming window.”
“Since Raspberry Pi doesn’t have a built-in ADC (Analog to Digital converter) to read the voltage off from most of sensors, the best solution is to add I2C ADC chips and modules to your project. Pawel Spychalski faced this …
“You have seen Propellers in Aircrafts or in marine ships, if not in real then in movies for sure. In this session we are going to design a Propeller Display with Arduino, LEDs and a DC motor. In this Propeller …
“What is our requirement? Here we want to measure the rpm of DC motor. So we have to measure how many times a particular point on the rotor undergoes a full rotation within a minute. So we have to use …
