DIY Temperature & Humidity & Smoke Detector Alarm System

The working voltage of this system is DC5V. It can measure the current temperature, humidity and smoke. It can display real-time data by the 1602 LCD and can realize the sound and light alarm when in the dangerous temperature and humidity. It is a simply and easily to operate monitoring alarm system about temperature humidity and smoke. Functions 1. When connected to the power supply, after the initializati ...

Modular DIY Geiger–Müller counter

The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of (low) radiation like soil, rocks (an article about my trip with Geiger–Müller counter on Śnieżka mountain). When high voltage (typically 380-420V) is ap ...

DIY Dual Stepper Motor Driver Shield for Arduino

Stepper motors are brushless DC motors which can move in discrete steps thanks to the special coil arrangement inside. They are very popular in DIY and industry projects which require accurate mechanical movement control.  In this SoloPCB Designer project, we are building a dual stepper motor driver shield based on two Allegro A4988 ICs which can supply up to 35V and 2A and provide overcurrent and thermal p ...

DIY FPGA-based HDMI ambient lighting

Ambient lighting is a technique that creates light effects around the television that correspond to the video content. It has been pioneered by Philips under the brand Ambilight. In this project we will create a basic FPGA-based ambient lighting system that reads the video signal over HDMI. This means we are not limited to computer output. We can use it together with DVD players, video game consoles, etc. D ...

DIY ESP8266 Development Board

ESP8266 is an 802.11 b/g/n Wi-Fi module which became very popular recently because of its capabilities and ease of use and integration. Many electronics hobbyists are building projects on ESP8266 and they generally need to connect the module to a PC or a microcontroller. Some interfacing problems arise at this point. In this project, we are building an ESP8266 Development Board which lets the user make conn ...

DIY: Arduino Based Ohmmeter

This is a project based on Arduino board which can measure the unknown resistance values and perform diode test and continuity testing. When we connect the unknown resistor on the breadboard circuit, the 16x2 LCD displays the resistor value and when we connect a diode the LCD displays the type of diode if it is a good one. When we take the probes out from the breadboard and connect it across a continuous pa ...

My DIY Automatic Wake Up Light

Every year I notice that I have little issue waking up at 7am during summer months, yet waking up at 8am during winter is always unpleasant. Some quick research led me to find that the body is gradually woken up by light, which is why products such as the Phillips Wake-Up Light exist. However, with  a starting price of £60 for the (very) basic version, I've opted to make my own smartphone-connected, automat ...

Daox’s diy arduino thermal differential controller

We have a great thread that contains lots of info on thermal differential controllers here. However, I wanted to start a thread dedicated to my own development of a thermal differential controller that I'll be using for my attic heat reclamation project. Tonight I setup a simple circuit that tested the operation of the differential controller and it worked great. Its very simple and adding features later on ...
