“Previously I had introduced simple raspberry pi (Hereinafter as RPI) operational status indicator circuit. This time, Ill explain some more useful indicator circuit for RPI running as headless (without monitor) manner. The circuit above shows CPU temperature into 4 different …
“This is a 8x8 WS2812b NeoPixel LED matrix that is completely flat surface and has the same 1.6mm height as a normal PCB. I always had this idea of what would have happened if we can put the components …
“Several years ago I built a CNC router with the express purpose of creating my own guitar. Unfortunately however, I never got around to it. Two years back I was getting into 3D printing in a big way and started …
“I wanted an efficient way of stepping down higher voltages from LiPo packs (and other sources) to 5V for electronics projects. In the past I have used generic buck modules from eBay, but the questionable quality control and no name …
“We all are familiar with Jarvis AI assistant robot from Iron Man movies and Marvel series. It has always been a dream of programmers to make something on their own. I will today show a simple way to make such …
“This pressure switch project is built using a piezoresistive transducer, LM358 OPAMP as comparator, and a relay. The circuit activate the relay when the pressure in a system exceed a given set-point. Basically, this switch can power ON or OFF …
“This motorized slide potentiometer is used in lighting and Audio/Video equipment or other similar application. It is a simple solution to control a motorized slide potentiometer using two tactile switches or a microcontroller interface. The project includes bidirectional motor …
“SG3525 PWM module is a great tool for every hobbyist. This circuit can be used in various applications such as switching power supply, DC-DC converter, DC motor speed controller, LED dimer, High voltage power supply, solenoid driver, and electronic …
“If you need to interface many devices and sensors to Arduino Nano, then, this project is for you. This is a Nano expansion I/O shield (breakout board) for the Arduino Nano. The board facilitates the easy connection between Arduino …
“This is a tiny module that allows users to charge small Li-ion batteries, CR2032 or equivalent, from a low power source such as a small photovoltaic cell. The project consists of the LTC3105 step-up DC-DC converter chip which features …
