Eletronics Design - March, 04th 2015
Maze |
This week our task was to produce a board that should have a button and an LED. The production this time included not only welding, but also drawing. It seemed simple, but again it took me many hours to decipher the path where the connections fit perfect allowing the correct assembly/operation of the board. After installing the Eagle and Fab library, I began to set all components in the schematic layer, which was quite simple. The real problem came after minutes when I really started drawing the board, and realized all these crossed lines that meant nothing more the inefficiency of my scheme. It took me hours "playing" this game that I used to play during childhood, maze, which the goal was to leave at once. Well, guess I should have played more... When Everything Seems To Be Right

First of all, you MUST understand what you are doing. To prepare the schematics is pretty easy, but if you are not sure about where, and what you are connecting the components, your board will definitely not work at all. That's why one should organize the project in stages (pre-term prototypes), even if all the components are chosen correctly. If there is no pre systematization, connections will be extremely confusing, making the task much more difficult. And it will take hours at the maze... Double (triple) check the schematics design and especially the connections in Eagle. After finalizing the design of the board, prepare it in Photoshop, send to the milling machine, and start to weld; even after much of the work done, I've discovered that the connections that were apparently correct at Eagle actually were not connected. A full day of work was lost at this point. Restart

Following the steps that we had two weeks ago and everything went fine. My board is ready! Everything is There
