Dia - Freeware alternative for MS Visio

Dia 8s roughly inspired by the commercial Windows program 'Visio,' though more geared towards informal diagrams for casual use. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

Cómo armar una bicicleta eléctrica económica

Armar bicicleta eléctrica
Es posible construir fácilmente una bicicleta eléctrica al utilizar una bicicleta existente y añadirle cinco partes: 1) un motor, 2) un enlace desde el motor hacia las ruedas o pedales, 3) baterías, 4) un acelerador y 5) un controlador de motor (el cerebro que regula cuánta energía de la batería enviar al motor en base a la posición del acelerador).

Aquí te presentamos la solución más económica, la cual consiste en una bicicleta eléctrica con un eje pedalier impulsado y sin piñón libre.
