Pico Authenticator Case
A case and a female to male adapter for the raspberry pi pico to be used as a hardware Authenticator. The requested funding will not be used for the case, I will be 3d printing it myself. The reason it is so high is because of the PCB shipping price as I dont live in the U.S. , which makes up exactly half of the requested funding. Btw, I looked and couldnt find any local pcb manufacturer that would produce the pcb for cheaer than jlcpcb WITH shipping.

You're not asking for funding?

done !
fixed the issue.
apparently i had forgotten to define the distance between the hole pins
i dont have much to say so im typing this to fll out the word count limit

Realized a mistake
I realized that every dimension is right but ive made a mistake on how far the holes on the pico are, so im going to correct it so it fits better
heres what i mean

Please include a screenshot of the final combiend cad model with all of your parts(if you export your pcb as a step file and import it into whatever cad software, that would be great) in your repo readme.

Hey! Could you please click on the little triangle next to the estimated shipping cost on JLCPCB and show us a cart screenshot of you selecting the cheapest shipping method? Global Standard Direct Line should be the cheapest, usually! Also please organize your files into PCB, CAD, and Firmware files if possible :)

As JLCPCB is out of your country, can you double check to see if they are any other providers close to you? Thanks :D

Can you include a cart screenshot that shows the shipping option you choose? We need to check that you choose the cheapest option :) (usually global direct!). Also include a full screenshot of the cart with your pcb in the cart!

Finished the case and cover, uploaded them to repo
I finally finished both the case for the electronics and the cover it slides into and uploaded them, i will now submit my request for a grant
wish me luck !

Provided a source for the code on the repo
https://github.com/polhenarejos/pico-fido
I will be using this one personally, totally optional to choose this one as well as you can run whatever code you want.
All credits go to Pol Henarejos, the coder.
I didnt have the means or the know how to code anything that complex so I will be using his code, which is under an open use agpl-3.0 license.

Designed the bottom half of the case
I designed where all the components would go on the case and what it would look like, using measurements from both easyeda and the pico datasheet.
Whats left is the top cover (whom I am yet to find a proper lock/latch mechanism for) and the button which will be rather simple: a whole on the top coverand a button that fits in it but has a wider bottom on the inside to not fall out
Also everything has like a 0.25 mm clearance to compensate for 3d printing inconsistencies.

Made the Github Repo
The PCB IS FINALLY DONE 1!11!!11!1111!!1!!!!
I made thje github repo and now im uploading the necessary files to it.
Whats left is the files for the case which will be printed which Im going to get done in a few.

Re Routed the PCB
Upon further research, I realized I didnt pay attention to anything interference related, any capcitors and wire thickness so I will be Re-Routing the PCB.
I have decided to take a little bit of help from chatgpt on what to do to meet the 480 mbps spec
Oh and i switched from a 24 pin usb c port to 12p, considering i was wiring the same thing to both sides anyway, which will help me a lot.

Routed the PCB
Finally routed the pcb (had to learn what vias are) and now its basically done, just have to change the case to fit the pcb.
Small tiny issue however, I havent the slightest clue if the PCB will actually work or short something and fry everything so I am actively looking for someone to peer review.
APPLICATIONS ARE OPEN (I need help asap)
(slightly joking with the applications but if you do decide to help, it would be very appreciated)

Learnt PCB design
I found out about the hacker card tutorial and started learning EasyEda Pcb design from it, now that I am comfortable Im designing the PCB that will be going into the project, and using te dimensions from it to correctly modify the case as well

Made an arbitrary design of the case
I modelled a prototype design of what i want the case to look like.
Its going to have a keychain hole, a usb c out hole and 4 pins to hold the pico in place.
I will have to modify the design in the future to have space for the pcba however, but I have no design to go off of yet so this will do for now.
