WEEK NINETEEN
-Project developement-
It has to be completed the final prototype with wood instead of PLA 3D printed and finish the programming.
what has worked? what hasn't?
The electronics design is finished after a lot of strugglying with possible options with the traces. I am stucked with the programming part,as I have always many difficulties to think about the code and it structure. But my schedule says is time to go for the design and leave appart the programming and start the design.
I had to change the shape of the design I had first in mind because of how the size of the board didn't fit on my first design. But we didn't have a lot of time left so I become up with this simple solution. A simple design box and compatible with the electronics PCB board. I made a first 3D printed rapid prototyping so at least I know that this volume works so next step is to make it the wood with the Shopbot CNC machine.
Time to change the design!
What have you learned?
I have realized that the electronics designed can take a lot of time of struggling to find the most efective solution and most of the time you do not know the size of it until you are not done with it. So the PCB board is the one that will determine the design later so it is better to first focus on the electronics design and later the design. The programming can be done at the end as it will not change the shape of the board.
