As you know, the BE-CO-HT section at CERN has been contributing to Kicad for some time now. We see this involvement as a key part of our activities regarding Open Source Hardware [1]. We are also contributing to the adoption of VHDL and System Verilog in the Icarus Verilog simulator, so as to enable cross-language

Brazo robot dibujante V2. (Monstruosidad tecnológica) Los resultados del brazo robot dibujante anterior no tuvieron una gran resolución. Mi idea inicial era hacer que pudiera escribir y eso resultaba impossible. Esto se debía principal mente a que cada paso de los motores paso a paso que uso es de 0.9° (400 pasos / rev). Cada
