This document outlines the 7 steps to modify an existing electronic apparatus in a class at the Universidad Nacional de Ingeniería. The steps include: 1) modifying a circuit using Eagle software; 2) entering all parts in schematic mode; 3) preparing an image for milling; 4) selecting pieces for welding; 5) entering information into Roland machine software; 6) making circuit tracks and cutting; 7) soldering parts to the board. The conclusions state that constructing the board is easy but Eagle software is difficult initially and inexperience can cause issues with milling.

Conclusions.
1. The construction boart is the easy part. All information take
it from the tutorials
2. eagle program is difficult at first but practice can learn

more.
3. broke the mill to make the lack of experience boart. academy
