HKU Assignment Hello all!Welcome to my HKU ITTT – “If This Than That” Project. For this assignment I created a simple eye test. The Distance Measuring Eye will give you a score based on the distance away from the eye. In this Instructable I will show you my thought process and the steps I took in creating this project. […]

For this project, I wanted to make something that would aid me while studying, so I made a custom timer to use for the Pomodoro Technique. This study technique involves allocating 25 minutes of uninterrupted focus to work/study, followed by a 5-minute break. I wanted a way to make my own experience with this technique more

Once I had made a project about the CO2 monitor that had such a problem. The displayed value changes too frequently and fluctuates greatly, which makes it impossible for me to accurately judge the CO2 level. I have a point to make it better now—record the history level and draw its to a line. Step
This project demonstrates the functioning of an “Ultrasonic Mono-pulse Tracker” built using two Grove ultrasonic sensors. Two sensors facing forward at a small angle from each other are placed on a servo pedestal capable of rotating +/- 60 degrees based on commands from an Arduino UNO board. The “Amplitude Comparison Mono Pulse” principle demonstrated here is
Let’s start of with a question: What is a people counter? …. Well, it is a device, that counts the amount of people passing by. They are usually placed in doorways and can be used to see how many people are in a room or a restaurant or a store at any given time. The
Persistence of vision is an optical illusion. When we look at an object, our eyes keep seeing an image of it for a fraction of a second after the object is removed. If several images appear quickly after each other, they seem to merge. My low-tech example is a piece of cardboard with vertical lines

This is a prototype version of the contactless switchboard which helps to control the appliances (AC appliances can be controlled through relays) without touching the actual switches. This can be used in public places like malls, hospitals, etc. In this pandemic time such device can be very useful. Supplies Arduino UNO (Any Arduino Board can
Greetings everybody! We hope you are in good health. In this Instructable, we will be converting a manual water tap into an automatic one using an Arduino. We will use an Infrared sensor to detect the presence of a human hand and a solenoid valve to control the flow of water through the tap. We
We’re spending the majority of our time on Zoom today, and yet we still keep forgetting to mute/unmute and embarrassing ourselves. Sure, the Zoom UI is far from perfect, but as makers, we should be solving our own problems ourselves instead of blaming it on tech companies: so here it is, a DIY Bidirectional Zoom Mute
LineaMeteoStazione, in the improved version, is a complete weather station solar powered which can be interfaced with professional sensors from Sensirion as well as some Davis Instrument component (Rain Gauge, Anemometer) It also can be interfaced with a less expensive set of anemometer and rain gauge from Misol. It also adds the feature of having a
