I found a cheap 4 wheel drive chassis on eBay and decided to make a remote controlled robot out of it. Thus, I made a simple board with two H-bridge modules, an NRF24L01 wireless module and Arduino pro mini.

When I was a university student, drones were starting to get popular so I decided to make my own. I made two attempt at the idea: The first attempt involved designing the most of drone from scratch, its mechanical design as well as its electronics, including the remote controller. After that attempt proved less than satisfactory, I designed a new version of the drone, this time with off the shelf electronics.

Global warming and the COVID-19 pandemic are some the many challenges humanity is having to face. However, I somehow decided that the problem I was going to solve is having to take my keys out of my pocket whenever I lock or unlock my front door.

This is one of my earliest electronics project: An alarm clock built around an Arduino nano, a real-time clock (RTC) module and a 7-segment display.

Physical buttons and switches do not switch between open and close position instantly and perfectly. Instead, they have a tendency to "bounce" between the two states before settling on one. This issue is thoroughly described in circuitdigest's excellent article. Consequently, when using such components with, for example, an Arduino microcontroller, a proper debouncing algorithm must be implemented.

Dogs are great at detering burglars from entering one's home. This system brings the same advantage, without the need for an actual dog.

This briefcase is fitted with an electronic lock and a fingerprint reader so as to be unlocked with a simple touch. It also features a bluetooth module, which enables unlocking using a smartphone or computer.

When I was in the army, we would often have exercises where we need to setup some equipment in the field and establish a security perimeter around to prevent access from unauthorized personnel. During those exercises, the sergeants and lieutenants would sometimes disguise themselves as enemies and try to access the equipment to see how successful we would be at stopping them. I didn't like the idea of staying alert for long periods of time and instead wanted to receive some kind of warning whenever a superior would be arriving in our vicinity so I designed a GPS tracker that I intended to put on his car.

This headset enables the overlay of information on top of its user's field of view. The field of view of the user is captured by a camera and then fed to video goggles, while a MAX7456 OSD chip overlays text on the video feed.
