Baby Surveillance Pi with sound and temperature
One project that i needed to complete with some urgency was a baby monitor. There are several types of monitors on the market, but the IP based monitors are expensive and the others don’t have enough range. There are several types of projects for baby monitors on the internet but none as wanted. Because of this, I decided to build my version.

Aquarium Controller using nodeMCU and MQTT
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.

Prusa i3 Enclosure
One of the problems that exist in the Prusa i3 3D printers is the open space and air circulation. This open space makes it difficult to warm the table, prevent it from reaching higher temperatures and makes it more difficult to maintain a constant temperature, which can compromise printing. If the temperature falls below a certain value, the part can be released from the table.
Marvin Night Light
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
How to make a Cross Cut Sled with wood leftovers
One essencial accessory for a Table Saw is a Cross Cut Sled. A Cross Cut Sled Is an accessory that allows to make straight cuts and always with the same size, as it supports the piece of wood on both sides of the blade, unlike the accessories that the table saw brings. In addition, it increases the level of safety in the use of the saw, … Continue reading How to make a Cross Cut Sled with wood leftovers
