MacTEMPtosh
Arnov sharma Aug 18,2022
Greetings.So this is the Mini MacTEMPtosh, a portable Temperature and Humidity meter that displays the current Temp and Humidity level by an onboard AHT10 Sensor.Its Body is made to look like the old MACINTOSH 128K Desktop PC so that's why it's called MacTEMPtosh.This setup is powered by an ESP32 Board and has a Lithium Cell as the power source.AHT10 is being used to measure the current TEMP and Humidity level that is being displayed on an SSD1306 OLED Display which is all control...

Cubik Lamp
KIMBAB Aug 17,2022
It has always been my aspiration to look at a daily product around my life and think about how could I improve and build a stronger relationship between it and the users. I chose to increment the desk lamp in this project. This object always sits on our table giving light when we need it to study at night. However, we humans need a break from studying from time to time, the usual activity during a break for today’s students is to play social media on a mobile phone. This is time-consuming, due t...

110/220VAC Opto-Isolated Zero Cross Detector Module for DIN Rail Carrier Mount with 3.3V or 5V Output - Ideal for Arduino, ESP32/ESP8266
TStar Aug 15,2022
This module detects the zero cross point of an AC supply and outputs a 3.3V or 5V square wave signal pulse of 1ms every time the zero point is crossed. For a 50Hz supply this pulse would be sent 100 times per second. This is ideal for micro-controller projects which require accurate synchronization with the AC supply, such as for controlling triacs to perform phase-angle control for light dimming or heater control. The AC side of the circuit is optically isolated from the DC side, providing impo...

Two Hand Multimeter With Arduino
ELECTRONOOBS Aug 13,2022
Full tutorial video: https://youtu.be/r83YSbyju8A This project is awesome, and I bet that you want one as well. This is yet the best multimeter I’ve made so far and let me tell you why. Well, first of all, is homemade, and that’s awesome, especially knowing that I’ve designed it myself. But second of all, it is very small but it has a lot of modes. It can measure voltage very precisely. The same for resistance and also capacitance. And if that is not enough, it can also ...

DIY Sensitive Arduino IB METAL DETECTOR (coin from 25cm big object at 100+ cm)
Pavleski Aug 13,2022
  A metal detector is an instrument that detects the presence of metal nearby. This time I will show you how to make a very sensitive, but simple to build "Inductoion Balance" type of metal detector made with the help of Arduino microcontroller and several other components. The Induction Balance principle uses two coils arranged in such a way that there is virtually no inductive pick-up between them. A modulated signal is fed in to one. When metal is brought near, the electromagnetic f...

Making a Digital Light Measuring Meter
Manoj kumar Aug 13,2022
While working on a home automation project on light, the light intensity unit- lux (lumens per square) comes to my mind. Summarizing, while light output is expressed in lumens, light intensity is measured in terms of lumens per square meter or lux. Both the units are different from each other. Let’s have a basic idea about them.Lumens (Lm) are the unit of measurement we use to quantify the amount of visible light the human eye can see. The luminous flux of a particular light source is measured i...
