My garage door comes with a motor and a 433MHz remote that I don’t always carry with me because it is quite bulky and in the way. Because of that, sometimes when I am in front of it and I want to open it, I had to go inside and press the trigger switch that

Ever asked how to control any device from any place in the world? In this tutorial, we’ll learn how to control things wirelessly over WiFi. Story Introduction Today, we will build a device that connects to the internet and allow the user to control his/her home remotely over wifi. We will use the Arduino board(any

A while ago, I made the ESP32 version of Midbar which later evolved into a multi-user Cipherbox. While developing the Cipherbox, I realized that even the Lite version of it might be too expensive and too redundant for some people, so I “resurrected” the single-user Midbar project and made an ESP8266 version of it. The purpose of Midbar is to

Cost-Effective MEMS Sensors Deliver Increased Performance and Reliability, Even in Unstable Pulsatile Flow and Low-Flow Conditions Posifa Technologies introduced its new PLF2000 series of liquid flow sensors. Designed to replace mechanical turbine flow sensors, the cost-effective devices deliver increased accuracy and reliability, even in unstable pulsatile flow and low-flow conditions. Factory calibrated for water to
Lumileds has added news LEDs to its Luxeon IR Domed Line with a significant increase in both DC and pulse drive current–up to 1.5A and 5.0A, respectively. The new emitters deliver radiant power of 1350mW at 850nm wavelength (slightly visible) or 1450mW at 940nm (invisible or covert IR). These new IR LEDs are engineered to
IR DOMED LEDS DELIVER UP TO 5.0A PULSED RADIANT POWER OVER 50° Continue Reading
In ancient times people used Hourglass to measure the passage of time. Hourglass is a simple device that consists of two glass bulbs that are connected vertically with a narrow neg and that allows the flow of sand or fluid from top to bottom. most of the time the flow duration is about one hour

In modern-day society, an increase in rail passengers means that rail companies must do more to optimize networks to keep up with the demand. In this project we will show on a small scale how temperature, rainwater, and vibration sensors on an arduino board can potentially help increase the safety of passengers. This Instructable will
“Marblevator, Pertual?, Cradle” like “Marblevator, Perpetual?, Version 2” and “Marblevator, Perpetual?” is not perpetual at all as it is simply another illusion. And like its predecessors it is a very quiet illusion with the only noise being that of the marble as it rolls back and forth in the cradle. I’ve incorporated an Arduino Nano

Every maker at least once make or tries to make RC Car. RC Cars are widely available yet the joy of playing with the one you made yourself can’t be compared with the bought one. So I decided to make a Wireless RC Car with the easiest available material i.e. Cardboard. No need for a
Remote Controlled Car Using Cardboard Continue Reading
I have toyed with the idea of building a clock for sometime and my sister had a big birthday coming up so I decided that this was a great opportunity to build a clock for her as a gift. My sister has a PhD in science and works as a science educator so I decided
