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.

A Node.js application which stores data from IoT devices sent over MQTT into an InfluxDB time-series database. It allows the management of multiple data sources into a MongoDB database.

Although probably in the decline, infrared is a common way to remotely control household appliances such as air conditioners or TVs. Being able to turn on an AC unit without leaving the sofa is definitely comfortable, but sometimes it would be even better to be able to do it before even getting home. In order to control those various appliances, I designed a simple WiFi controlled IR emitter.

I got my hands on a 600W 12V inverter so I decided to experiment with generating my own electricity.

My router needed to be replaced. However, instead of buying an off-the-shelf router, I decided to give pfSense a go and install it on a second-hand desktop computer.

Keeping track of one's body weight usually involves manually writing down measurements on a spreadsheet or similar. To automate the process, I removed the electronics of a cheap scale, keeping only the load cells, and replaced it with my own.

IP cameras are cheaper than ever and with the ESP32-CAM boards it is now possible to stream video for less than USD 10. However, IP cameras are commonly either only accessible from within their network, or use servers from third party companies to allow users to see the video feed from anywhere in the world. As both scenarios are inconvenient, I decided to create a camera viewer application that can proxy the video feed to a web interface.
