Arduino Nano 20KHz pocket sized Digital Oscilloscope

“A difficult code with a try to display waveform on a small screen with precisions. Volts-time, frequency, duty cycle and divisions. Previously, I posted a tutorial on Raspberry Pi-Pico Oscilloscope. And that was a great success. Keeping portable options in …

DC-HV DC Converter – 200V @ 20mA Output with 12V DC Input

“This is a low-cost DC-HV DC converter built using TL3843 Low-Power Current-Mode PWM Controller from TI. Screw terminal connectors are provided for input and output, onboard LED D1 indicates the input supply. The project provides 200V DC @ 20mA output …

HomeMade Arduino Jet Engine

“Have you ever tried to create a real spinning Jet yourself! checkout the detailed making steps in this Hackster post. As usual I made this tutorial to guide you step by step while in case you decided to experience the …

PCB Heart Necklace

“Made a heart-shaped PCB Necklace for a special one <3”

PWM Temperature Controlled FAN using TC648 and NTC sensor

“The project described here is a switch mode fan speed controller for use with brushed or brushless DC motors. Temperature proportional speed control is accomplished using pulse width modulation (PWM). 10K Ohms NTC is used to sense the temperature. The …

CO2 Level Indicator (4x7 Segment RGB LED Manual Calibration)

“This DIY project shows you how to make your own CO2 level indicator, which shows you CO2 concentration (PPM - parts per million) when button is pressed and always on RGB LED shows constantly how good or bad your surrounding air …

DC Motor Controller using Relay and MOSFET – Arduino Interface

“The project presented here is a low-cost solution to control high power brushed DC motor speed and direction. Traditional DC motor controllers are based on solid-state circuitry known as H-Bridge. Here we have made an H-bridge configuration using high current …

Desktop Analog Spectrum Analyzer

“This spectrum analyser with 10 channels uses an analog back-end to analyse the incoming signal from line-in or microphone. Acrylic display. The analogue back end of this 10 channel spectrum analyzer uses 10 band pass filters to divide the input …

Dual 40W Audio Power Amplifier with Mute

“The stereo audio amplifier project shown here is capable of delivering typically 40W per channel continuous average output power into an 8Ω load with less than 0.1% (THD+N). The project is built using an LM4766 chip from Texas …

Introducing the ATtiny Device PCB - I2C slave devices

“Ever since I started playing with Arduinos and microcontrollers, I was always fascinated by one very specific chip. The Attiny85! I know, I know! It’s not the fastest microcontroller out there, nor it is the best but being so …
