VFD Alarm Clock

IV-27M Alarm Clock Project date: March 2019 – May 2019 Overview After the successful completion of the XIV Nixie Clock which was Direct/Static Driven, I was keen to start work on a new clock which was based on the Multiplexing(Dynamic) or “MUX” principle of operation, known also as “Muxing”. The new clock would be based on the USSR manufactured IV-27V VFD, 13 element, 7 segment tube. This tube requires a 24 ...

RK Clean Air – A Gas, Smoke, and Carbon Monoxide Detector

Rk Clean Air is a gas responded device that is capable of monitoring gas leakage, smoke, and carbon monoxide leakage in the home. According to the National Fire Protection Association, “Three of every five home fire deaths resulted from fires in homes with no smoke alarms (38%) or no working smoke alarms (21%) and the death rate per 100 reported home fires was more than twice as high in homes that ...

Sunlight Detection Alarm

Most technology Instructables are fun to construct, and often easy to build. This is one that shares those features, but also solves a practical problem we had. To prevent fading of furniture, carpet, and the wood flooring in our foyer, my spouse and I installed one-way blackout shades. However, after installation and use, a problem arose. The air in the foyer began to have a slightly “musty” odor as no sun ...

Creating a Smart Water Sensor with the ESP32 Thing

Over the Christmas break, my parents were out of town to celebrate the holidays. When they came back, they saw something every homeowner fears – a flooded basement. In a basement, there are pipes that collect water from around the foundation and bring it into the sump pit, which pumps it out away from the house. When the sump pump fails, water has no way to leave the basement and it floods. I recently bough ...

Alarm System

The objective of our project was to create an alarm system that could detect an intruder using an IR motion sensor. We used a keypad so the user could enter their password to arm and disarm the system. [gallery columns="2" size="medium" ids="31154,31155"] We also included an LCD so that users would be informed which state the alarm system was currently in as well as giving the user a response when entering ...

Interfacing Flame Sensor with Arduino to Build a Fire Alarm System

In this article we interface Flame Sensor with Arduino and learn all the steps to build Fire Alarm System by using Arduino and flame sensor. Flame sensor module has photodiode to detect the light and op-amp to control the sensitivity. It is used to detect fire and provide HIGH signal upon the detection. Arduino reads the signal and provides alert by turning on buzzer and LED. Flame sensor used here is an IR ...

Smart Phone Controlled Arduino Mood Light with Alarm

Smart Phone Controlled Arduino Mood Light with Alarm I recently purchased the Neo Pixel LED strip and was quite impressed by the way it works. The tiny LED’s have an inbuilt driver IC which helps us to control each LED individually and can produce a wide spectrum of colors. Being a garish person who is obsessed with colours I really loved watching these tiny LED’s changing colors so I decided to build somet ...
