During the process of building the PiMassive I kept putting off the GPIO constantly I was unsure of what I was going to do with it but I knew it would work in the end so that is what I did now not all of it is hooked up at the current moment that I am writing this but it will be soon enough for testing I wanted to make sure that the 5v and 3.3v. as well as the ground was working. I really wanted to design some custom cables to connect to it as well but due to the time and the amount of time I had put in to it already it wasn't in the books for this challenge. Maybe later on I will make them and get a few more of the components working as well.
So I designed the gpio with through hole with a few layers on the bottom so I could drill into it if I choose to go with the 3D Printing of the GPIO which due to the time once again and the nozzle breaking prior to the printing of them I had the .8mm on and was trying to print the pins at some point was getting some really terrible prints because not testing the settings right away and jumping into a print right away hoping you can adjust them on the fly make for some really awful prints.
It was off to amazon to get some new nozzles sent but I couldn't stop printing I had to have something for a backup in the worst case scenario.
I really wasn't sold on the GPIO Being 3d printed so another thought entered my mind to use square rod but then after not having the right size within a 100km radius of me. and the fact it would cost me $3 dollars each and would need a bunch of them I think I would only get 2 or 3 pins out of each. Now if I wasn't going to make the GPIO working I probably would have used them just for the look and hit each pin with the bench grinder to shape it but I wasn't going to waste that much money when I can do it another way. That would only cost a few dollars for the screws.
I oped out of that one and it was back to the 3d printing of the GPIO pins.
Many multiple prints later and finally my .4mm nozzles showed up I was able to get more printed I salvaged some of the pins I printed with the .8mm nozzle figured some sanding would make them look some what usable.
So after I completed the 3D prints I cut them in half on the bandsaw which made quick work of cutting them in half I was able to do 5 or so pins at a time then it was off to final sanding and then paint touch up.
Alright lets head over to the next post here and have a look at the placement of the pi and the wiring of the GPIO and how I got it all connected
