For some time ago I had three Lack shelves, one white, one yellow and one blue from Ikea. They were stored with no specific purpose. Since I was in need of a shelf for the office, i create a stand and recycle them. For this I used three 4cm by 4cm of pine.
In the last halloween I decided to create a project for the season. Using a 3D model of a ghost that i printed on the Prusa i3 and the Cheerlights project i created a Halloween decoration that changes color randomly.
The Cheerlight project is an open-source project that synchronizes all light devices that use’s it. Through Twitter, using the #cheerlight hashtag, we chose a color from the Cheerlights project color palette. All devices that are connected to the project Cheerlights read the color through the api and change their color to that. Through a tweet it is possible to change the colors of all the devices of the planet connected to the project.
One of the problems in photography is exposure. For a good photography a controlled environment is required, both at the light and at the environment level.
To solve the location problem I have acquired a lightbox, which allows you to define several uniform backgrounds to create contrast. But it was still necessary to solve the question of luminosity. For this I built my own lighting system, used Ikea frames, led strips and some components.
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.
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.
