Highway to Undercity

Total time: 21hrs 30m

Final notes:

CAD couldn't prepare me for every design issue I ran in to at the integration hell stage. There are a lot of minor design flaws, and I've learned a LOT. Stay tuned, I may give this a second shot, with the goal of perfecting this project (never gonna happen, but it's a good goal to aspire to).

August 2:

Did a bunch of work on the display, and it fully works now, so...

July 22:

Project complete!

I iterated the case mount several times over the past few days, and finally got it to a place where I like it:

July 15:

All the parts have finally arrived, and I'm back from undercity! I just finished soldering everything together, though I think I might redo the standoffs for the screen with a custom 3d print. I tested the hat, and it seems I got lucky, It's outputting 5.25v which is just on the edge of the Pi's 4.75-5.25v acceptable range.

30m

Ordered parts after a ton of struggling with JLCPCB's website!

Today is mainly preparing to submit since I'm leaving for vacation tomorrow. JLCPCB's website is still refusing to works, so I might not have a good quote on the PCBs. I cleaned up the repo, made final changes to the PCB and CAD, and went over all the guidelines. Also made some relatively minor cad changes.

JLCPCB's website FUCKING SUCKS

In the very real case that PCB assembly gets pricey, my contingency plan is to solder the top myself. Also added RJ45 passthrough in CAD:

5hrs

Also put in screws, etc: Took an eternity, but I finally figured out how to mount the board in there!

Today I'm back in CAD. it took me forever, and quite a few revisions, but i finally got these things that will eventually support the pi kinda working, and properly mating, The ridges were a massive pain, even though they're key to my design:

oh and i have no idea how to mount the board in the case, im thinking something like what i have drawn below, i want to make use of the existing ribs to support the pcb: ALL HAIL OUR LORD AND SAVIOR: https://lcsc.com/product-detail/image/FH-00205_C2685098.html:

Back in CAD today, and while mocking up witrh a Pi, I realized that the header I'm using isn't quite tall enough, so I'm going to have to replace it: (if you zoom in you'll se that the USB ports is clipping into the PCB)

Copied in my power circuit from my previous trail project and got it layed out. Pic coming soon.

June 7:

v1 of pcb layout is complete! put it in cad and now have a good basic mockup:

fuck around in cad/easyeda
