One of the problems of a server room is the temperature. With different equipment producing heat, this rises quickly. And if the air conditioning fails, it quickly stops everything. To predict these situations we can acquire one of several environmental monitoring systems in the market. Being a simple system, I decided to make a custom solution and build a server room monitor system. Thanks in advance for the support of PCBWay that provided all the necessary pcb’s.Continue reading “Server Room Monitor”
As usual, this Halloween I decided to create a project related to the season. Using Prusa I3 and Thingiverse, I printed a Halloween decoration where the color is controlled remotely through the Blynk project.
The Blynk project lets you create a mobile or tablet app that interacts with controllers like the Arduino Uno or the Wemos D1 Mini.
For some time now I’ve been trying to change the lighting in the kitchen counter. It uses halogen lamps and wasn’t practical. So I decided to replace it with a LED strip. In order to automate it i added a wemos. Let’s begin.
For some time now I wanted to start automating parts of the house. Although several parties are already planned, I decided to start with the aquarium.
Currently the aquarium has two analog timers to control lighting and water filtration. The problem is that whenever there is a light fault, the timers change the lighting and filtering times.
To solve this problem, I decided to install a nodeMCU module, which receives water temperature data through a probe, controls lighting and filtering through a relay, and communicates with the Raspberry Pi that controls all IoT (Internet of Things) through MQTT (Message Queuing Telemetry Transport) messages.
One of the projects, which was scheduled some time ago, was the construction of a personalized presence light. For this project I decided to use a wooden base with an Arduino and a figure printed in 3D. First the bases were cut. Due to the low height of the wood it was necessary to cut two pieces, prepare them and to glue it. Two circles … Continue reading Marvin Night Light
