Identify noxious air bubbles lurking in the substrate w/ ultrasonic scans and assess water pollution based on chemical tests simultaneously.

The future of air transport

In this project, we will build a tiny internet clock connected to your wifi to get time from NTP servers.

This project aims to accelerate the process of identifying soil density values from the subgrade, subbase, and base course layers by integrating vibration, speed, and acceleration sensors connected to an Arduino Mega 2560 microcontroller. The data generated enables real-time monitoring and adjustment during the compaction process in accordance with SNI (Indonesian National Standard) 1738-2011.

In the year 2021 I created a "Internet Hardware WatchDog" using NodeMCU which reboots my home router whenever there is an issue with the Internet. This device sits next to my router and happily takes care of it whenever it has a hiccup. This year, I wanted to extend the watchdogs horizon by adding an "Internet Status Notifier" that displays the current status of the Internet using an RGB LED.

“The Cyber Clock” , A rechargeable battery-powered 1.51-inch transparent OLED clock with accurate internet time and date. It can also measure your room temperature and humidity from an onboard sensor. It can show the battery percentage as well, with a fully 3D-printed Cybertruck body. It also comes with rollable wheels so you can play with it. It is also possible to lock the wheels by tightening screws so it wouldn't fall from the desk by accident !.

Artificial plant with environmental monitoring

Buying a ready-made power supply would be too easy, so I decided to make my own.

My curiosity to create something new and interesting got me into this gothic style rechargeable lantern. A Gothic Lantern is a captivating piece of lighting that brings the allure of the Victorian Era into your home.
