Why I use Blender There is always a lot of discussion on wich 3d modeling tool is the best to learn and use, most of the time it comes down to personal preference and becomes an almost religious fight. In my opinion we should talk and think about some other aspects on why we choose one tool or the other, here are some thoughs: The tools that we use, shape ourselves and the things we do. The design of the tool, limits our capacity to create solutions, and influences how we face problems. Our creative freedom has to struggle against the rules imposed by the tool itself. The reasons that motivate tool designer decisions are not always aligned with our objectives. In commercial tools, profit is prioritized in design decisions.

El proyecto Raspberry Pi The Raspberry Pi project originally leaned towards the promotion of teaching basic computer science in schools and in developing countries. The original model became more popular than anticipated, selling outside its target market for uses such as robotics. It is widely used in many areas, such as for weather monitoring, because of its low cost, modularity, and open design.  Hardware y modelos de Pi's A lo largo de los años la fundación Raspberry Pi ha liberado diferentes modelos de placas: Generación Modelos

Analog <> Digital * To allow our devices to be aware of their surroundings we use sensors that translate the information of the enviroment in electric signals. This signals are normally analog, and because the electronic systems (mostly microcontrollers) we use to process this information and take descitions live mostly in digital world we need to translate analog values in digital ones. To express or actuate in the real world our devices need to do the oposite: convert our digital information in analog outputs (leds, motors, etc) Our world is analog, it has an infinite number of values for light, sound, etc. Digital signals are finite, depending on the resolution we use we have more or less values. Ploting signals against time let us understand them

Conceptos básicos Carga eléctrica Los objetos pueden tener una carga eléctrica positiva, negativa o no tener ninguna y ser neutros. A nivel de las partículas subatómicas los protones tienen una carga positiva, los electrones negativa y los neutrones son, como su nombre nos indica, neutros. En los átomos, el núcleo contiene a los protones y neutrones mientras los electrones orbitan alrededor. Energía Los electrones pueden ser forzados a salir de su órbita alrededor del núcleo si les aplicamos energía. Al hacer esto creamos areas con una carga positiva y otras con una carga negativa (como son los polos de una batería). Voltaje
