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
One technology that came up with 3D printers was 3D scanning. There are several equipment that allow you to do this, some more accessible, some less. Some time ago, BQ launched a model called Ciclops. It’s a relatively affordable 3D scanner just like others on the market. However it has a unique particularity. BQ, in addition to launching the scanner for sale as a kit, … Continue reading BQ Ciclop Home Made
One of the places where I collaborate is at FabLab Castelo Branco. Not as an employee but helping when needed. The latest help was preparing a mUVe 3D DLP 1.1 printer. A DLP printer is a 3D printer that, instead of melting filaments and layering them, uses a proprietary resin that is cured over a given wavelength. This wavelength can be generated through several means, … Continue reading mUVe 3D DLP – Configuration and working
One of the things we wanted to acquire, for some time, was a 3D printer. But taking into account the prices and maintenance I decided to assemble my own. I decided to assemble it because the cost is lower and when it is necessary to perform maintenance, i know exactly what part purchase, where to buy and how to replace it.
