2 Channel PWM to Analog converter
YT Nov 27,2025
This is a PWM to analog voltage converter. Given an input PWM the output will be proportional to the duty cycle of the PWM signal.It can work with any MCU, arduino, esp32, stm32 etc.. As long as the supply at the circuit is 3V-40V (tested up to 35V). For example a 1.8V (or less) pwm signal can be used as an input but you should power the circuit with at least 3VThere is an adjustable RC filter whose cutoff frequency can be adjusted from 33mHz to 33HzThe circuit offers also the possibility to app...

TempGun Pro
Arnov sharma Nov 24,2025
Greetings, everyone, and welcome back. Meet TempGun Pro, a handheld open-source infrared temperature capture gun powered by ESP32 C6 1.47 display, and a custom circuit.The aim behind this project was straightforward. I needed a temperature meter to measure different things while working with electronics and 3D printing. I already had a Fluke temperature gun, but when it stopped working, I needed an urgent alternative, something cheaper that could still perform almost as well.The best part was ho...

Arduino IO Expander
Nov 23,2025
This IO expander plugs into an Arduino Uno to add more controllable pins. It can be used for instance to interact with TTL circuits. One configuration can be 24 bits output and 8 bit bi-directional. Replacing the 74HCT245 chip with a 74HCT573 will give 32 bits output only.The schematic and layout are design with KiCad 9.The repository contains an example code to test a RAM chip on a breadboard connected to the expander as address bus, databus and control signals.Here is an example to test the He...

Audio reactive glow LED wristband/bracelet with NFC / RFID-Tags
Loeffler Nov 19,2025
A rechargeable glowing wristband that reacts to music, powered by a thin LiPo battery. The TPU band has 15 LEDs inside. The animations are driven by audio analysis and controlled with an ATTiny85 processor.Why did you make it?I like electronic music events and festivals and my wife likes to dress up so I wanted to bing this together. I enjoy the synesthetic aspect of sound and light in a good club and so am I always trying to make the lights dance.Technical detailsAdjustable diameter: 5 - 8...
