nRF24L01 module

nRF24L01 2.4 GHz transceiver module

The nRF24L01 is a low cost transceiver module that operates in the 2.4 to 2.5 GHz frequency range and uses FSK, GFSK, OOK and ASK modulation techniques to send packets to other radios in the area. The radio also has a built-in voltage regulator that allows it to operate with 5 or 3V power supplies, making it easy to implement in projects. The module can be used with an Arduino board or with any other microcontroller equipped with an SPI interface or pin header for its pins.

Color theory

Color theory

Paintings, stained glass and other types of art all rely on the use of color. It is important to understand how colors interact with each other and affect our perception. The basics of color theory are easy to understand, but they’re also important if you want your work to stand out from the crowd.

Scale model

Scale model

A scale model is a small representation of a larger object, usually in miniature. Scale models are used for several reasons, including visualization and design work. In some areas such as industrial design, their method is the only practical one available to visualize the proposed concepts before the fields used or tested. For example, in the automotive sector prototypes can be built using original designs with the aim of “demonstrating” the feasibility of the concept before production begins.

Freecad what is

What is FreeCAD?

FreeCAD is a parametric 3D modeler made primarily to design real-life objects of any size. It is also great for architecture, engineering and construction projects. The FreeCAD application is written in Python and uses OpenCasCade, a powerful geometry kernel, for 3D operations. It’s open source, with an active community of developers and users.
