Currently, in Peru, the study of satellite images is increasing because it has the Earth observation satellite PeruSat-1. However, the cost of implementing a ground station is very high; for this reason, it is baffling that each university has its station. In the present work, the design and implementation of a low-cost portable earth station for the reception of meteorological satellite images is proposed in an automatic way, using accessible electronic devices such as Raspberry Pi 3b +, Software Defined by Radio (SDR) and an antenna double cross four dipoles, in this way encourage the study of satellite images in schools and universities. The results obtained show the viability of this project.

At present, the poor management of Waste Electrical and Electronic Equipment (WEEE) puts the environment and the health of the population at risk. In 2018, more than 50 million tons of WEEE were generated worldwide. Electronic waste is more dangerous than plastic waste, as much of it is composed of various toxic elements. In this sense, this research aims to develop a system of Computerized Numerical Control (CNC) from resources composed of WEEE for the drawing of Printed Circuit Board (PCB). By taking advantage of some electronic elements and devices that make up the WEEE, it is proposed to give them a new use, preventing them from becoming waste. Once the proposed system was implemented, a CNC machine was obtained for PCB made of materials collected from WEEE, which makes drawings whose dimensions reach a maximum area of 10.
