Just ordered :)
Just ordered the PCB from JLC with my own funds. Hopefully this time it works and i can acually use it :) I ordered it black and ima going to move onto thinking about how to do the keycaps so they look really cool.

More routing
I am doing more routing have done the edge cuts and finished top two rows of the swithes. I want to add leds but its a bit complex, maybe next time i think.

Ok lets do it again
So basically i switched the pinout. I figured it was easiest to delete everything in the PCB editor and start again. Next i will add the edge cuts i want to add test pads this time.

I am crashing out
After about 30 minutes of troubleshooting, stupid me looked at the datasheet for the Hall EFfect sensor and found out that i put the pinout wrong. WElp here goes another week of my free time :(

Hey William, this seems like a really cool project, but this is a max tier three. Please try to optimize your BOM, or pay the rest using your own funds. Even if the switches are an essential part of your project, most full size keyboards use choc or cherry switches...

Changed some stuff
Reviewer said i have to cost optimize my thing so i removed the keycaps so i will 3d print them mysel;f and also changed the multiplexers from mouser to lcsc to avoid shipping.

Hey William, please optimize your BOM to be cheaper! I also don't see your case so please add an image of your final project in your readme and update your journal with photo's of that too!

cHANGED the BOM
I changed the BOM and also changed the readme cause i realised in the bom my multiplexer was out of stock in LCSC so i switched to Mouser. I also relised that the price was off now and also i didnt put screenshots of my other shopping carts everything is in the README.
Reviewer Please Check the README!!!

Ok did the code
BTW IMPOORTANT::: THIS CODE IS VIBE CODED i think it is allowed but if it isnt please ban me cause i know that it is vibe coded cause in the docs it didnt say i couldnt vibe code the firmware. ChatGPT is goated:)

Done with the PCB
fINISHED the edge cuts but i need to put the stabilizers in but those footprints are on my PC so rn i have done everything. Wehn i get home ima gonna do the readme and bom.

Mrkeyboard

99% done with PCB
fINALLY FINISHED PCB ! now all i need to do i the edge cut the bom and the readme so exited to see this project come to life now !!!!!!!!! Will try finish by the end of next week :)

nearly there
Finished Routing the switches and wil now wire up all the pins for the multiplexers. after that will work on mob and some software. Then i will ship for the first time :)

Started PCB
Started PCB but ran into a problem where two components in a singular footprint was too close. Had to restart i just finished routing key 14 out of 61.

added to the journal ago
Did stabilizer things
CReated footprints for my stabilizer because i couldnt find them anywhere spent a good 30 minutes trying tho they are the gateron low profile stabilizers.

Fixed ERC
Ran ERC and fixed problem of the adc_vref not connecting to anything it is fixed now so tommorow i am going to move onto doing the footprints and acual pcb should be ready in about a week :)
warnings are just extra pins

near finish shematic
Finished with footprint and symbol fot the switch now doingthe shematic currently wiring the 61 switches up to some analog multiplexers that go into a rasberry pi pico

Mrkeyboard
added to the journal ago
doing the schematic
finished symbol and Started doing the schematics added 61 switches 4 multiplexers and the rasberry pi pico next wil finish and then move on to pcb stuff.

added to the journal ago
Finished Footprint
Finished footprint for the magnetic switch was going to put per key rgb but then figured to complex as that would exeed the amp rating of the pico which would force me to use a usb PD breakotu board. Now going to do the symbol for it and then i will start on the schematic

Mrkeyboard

Starteds on the thing and also started on the footprint
First i started by creating the BOM and the plan file then i started on the footprint since i couldnt find any available footprint for my gateron low profile magnetic jade switch, i decided to make my own i have just done puting the sensor unter the place on the footprint next im going to move to the symbol and filling in the BOM
