Board Design & Developpement

Old Versions (1, 3)

I use KiCad. which i tried and tried until i found out i had to use some nighly build because pre-6.0 versions are just the worst to use (the 6.0 wasn't out yet)
First version used Elite C microcontroller a Pro Micro clone. I lost my shit when i had to build a firmware with QMK tools.

I had some pcb routing errors, i scrapped all the QMK stuff and went for something easier and appealing in Micropython/Circuitpython. And I learned I cannot do matrixes over a MUX and direct inputs from the board -despite all the documentation I read. i need to read docs better. The last PCB i did was ok-ish.

Current Version (6)

That one is actually perfect, no routing errors, no more uses of multiplexers, more barebone. An it can goes with a lot of boards such as Arduino's Pro Mini, Sparkfun's Pro Micro. Elite C board. Any controllers with the same form factor as Pro Micro can go.

Intended to use this version with AdaFruit's KB2040|RP2040 "KeeBoar" for testing purposes. It supports Micro/Circuitpython, and i saw it can be flashed with Arduino code too.


Enclosure Design

Screenshot of the case's project in FreeCAD

Early versions used cardboard the same folds as a shoebox.

I've dabbled FreeCAD for this kind of work. i didn't designed many enclosure cases design. it's my first time. I don't have a 3D printer so a friend is actually give me some help there. It use additionnal parts 5 M3 female threaded knurled nuts with 5 round and cruciform (Philips) M3 screws.

Little revisions

Due to the size of my friend's 3D printer i have to cut every piece in two


Assembly

Prototype is finished

3D printed in 4 parts with a newly built Prusa MK3S+ Printer. All parts needed revisions after the print.

60% keyboard, with big keys

Version 1

no prototype for now (04/2022)
The project is based on pure fun, coined by a friend. I just want to make a 60% keyboard with 0.25 added on each key. for big fingers. make dreams come true.
Unless the Ortobi this one will work with any microcontroller because i didn't make room for the microcontroller. but i also want to try some SMD soldering but i don't know yet what i really want to try with that one!

Finished Board, Case Designing (11/2022)
So i didn't talked much about that one. I did finished it the board on stream and so far i'm on the case design. Much differences from the Ortobi.
