Keyboard Computer: a keyboard that can run python and compile C++

Here’s wat I did for the past 1.5 hours

• Updated README and Release
• Rerendered PCB
• Cleaned up DRC and replaced 0.1 uF with 1 uF for 3V3 and 1V1 according to RP2040 hardware design
• Added more vias

Well I changed the routing a little bit and removed two capacitors cuz they were kinda in the way and not very important
Anyway I think this might be the last devlog

OMG I just worked 3 hours on this and my tic-tac-toe card and im now just devlogging this after I did for the card

• Created git release
• Rerendered 3D model (this one looks better trust)
• Upload the model to sketchfab
• Added some final touch to my README

• Rendered keyboard using blender
• Watched tutorials on how to simulate metallic textures
• Configured new preferences
• Exported STL using fusion 360
• Learned how to resize file through FBX
  The rendered keyboard is gorgeous!!! Btw the cherry keys are actually not metallic but it looks nice in the render so imma keep it lol

I just noticed that I forgot to save the latest version of my PCB design………!!! So I spent a little time fixing them, including adding vias and running DRC to make sure everything works out fine

W DRC :)

Cleaned up and published everything online

Im so done with this but it was mostly finished!!! I will ship this right after some clean-up

For the past two hours I have been routing all the components, reducing ratlines from 200 all the way down to 20

• Connected all columns and rows
• Swapped some pins, such as moving all the column pins to the left
• Added GND vias (still more to add……

AHHHH SO FRUSTRATING!!! Apparently, it was not as easy as I thought, so many traffic jams

GUYS am I cooked……?

Here are the changes I decide to make:

• Move USB Port and the Chip to the top
• Replace THT diodes with SMD diodes (ik ik I said THT was better but im taking that back lmao

GUYS IM SO DONE WITH THIS……I was rewiring everything cuz of the stabilizer. I moved all the chips to the back and im SO DONE WITH THIS

Took me an hour to wire mostly everything up. Luckily I have the experience from RP2040 devboard and more space to spread out the components

BUT BUT BUT I just realized that I need some space for space key stabilizer!!!!!! AHHHHH BRO IM COOKED CUZ I GOTTA MOVE EVERYTHING AGAIN AND REWIRE THEM

Here were the things I did for the past two hours:

• Repositioned RP2040, crystal, and flash storage. Eventually, I flipped them to the front cuz it’s just cooler. Imagine if you can see all the internals you’re typing lol
• Move each row of diodes up to avoid unnecessary intersections
• Started routing, connected rows and columns and wired up USB port data traces
• Added copper zones and spread out the components

I finally placed every down in suitable positions (hopefully we’ll see when we get to routing
I also changed all the diodes from SMD to THT so that I don’t need to use via everywhere, and I could literally just trace either horizontally or vertically anyway I want

Question: Should I place USB port on top right corner or bottom right?

AHHHH THE MOST ANNOYING PART, here were the things I was trying to do:

• Place all the components in suitable positions
• Calculate the width of D+ and D- for USB
• Find tutorials to make sure everything is alright

Trust me patience is the secret sauce!!

For the past hour, I have been wiring my keyboard and I gotta be honest it was much easier than an RP2040 dev-board as there was much more space. Enjoy the process!!!

I completed the key layout and also decided to move all the diodes and parts to the back

Completed the schematic and the footprints!!!

Based off the experience from the two previous projects im finally now working on a full-size keyboard with integrated RP2040!! I just copied and pasted my my schematic from RP2040 and made some modifications specifically for keyboard, and I also mapped key switches
