Capyboard, ESP32 Development Board for Education by emiler

Description

Capyboard is an ESP32 development board built to accept individual custom-made modules. The board is created primarily for use in education, where you want to focus on embedded programming instead of spending time with connecting cables and parts on a breadboard, as you would with Arduino and other such devices. The board is not limited only to education and it can be used to build, for instance, a very powerful internal meteo-station and so on.

I already have one initial prototype ready and tested. The next iteration addresses several issues the first prototype had. I am planning on finishing up the mainboard and one of the modules this week.

This project is also a part of my master's thesis.

Goals

• Finish testing of a new prototype
• Publish source files
• Documentation completion
• Finish writing thesis

Framework laptop integration by nkrapp

Project Description

Although openSUSE does run on the Framework laptops out-of-the-box, there is still room to improve the experience. The ultimate goal is to get openSUSE on the list of community supported distros

Goal for this Hackweek

The goal this year is to at least package all of the soft- and firmware for accessories like the embedded controller, Framework 16 inputmodule and other tools. I already made some progress by packaging the inputmodule control software, but the firmware is still missing

Resources

As I only have a Framework laptop 16 and not a 13 I'm looking for people with hardware that can help me test

Progress:

Update 1:

The project lives under my home for now until I can get an independent project on OBS: Framework Laptop project

Also, the first package is already done, it's the cli for the led-matrix spacer module on the Framework Laptop 16. I am also testing this myself, but any feedback or questions are welcome.

You can test the package on the Framework 16 by adding this repo and installing the package inputmodule-control

Update 2:

I finished packaging the python cli/gui for the inputmodule. It is using a bit of a hack because one of the dependencies (PySimpleGUI) recently switched to a noncommercial license so I cannot ship it. But now you can actually play the games on the led-matrix (the rust package doesn't include controls for the games). I'm also working on the Framework system tools now, which should be more interesting for Framework 13 users.

You can test the package on the Framework 16 by installing python311-framework16_inputmodule and then running "ledmatrixctl" from the command line.

Update 3:

I packaged the framework_tool, a general application for interacting with the system. You can find it some detailed information what it can do here. On my system everything related to the embedded controller functionality doesn't work though, so some help testing and debugging would be appreciated.

Update 4:

Today I finished the qmk interface, which gives you a cli (and gui) to configure your Framework 16 keyboard. Sadly the Python gui is broken upstream, but I added the qmk_hid package with the cli and from my testing it works well.

Final Update:

All the interesting programs are now done, I decided to exclude the firmware for now since upstream also recommends using fwupd to update it. I will hack on more things related to the Framework Laptops in the future so if there are any ideas to improve the experience (or any bugs to report) feel free to message me about it.

As a final summary/help for everyone using a Framework Laptop who wants to use this software:

The source code for all packages can be found in repositories in the Framework organization on Github

All software can be installed from this repo (Tumbleweed)

The available packages are:

• framework-inputmodule-control (FW16) - play with the inputmodules on your Framework 16 (b1-display, led-matrix, c1-minimal)

• python-framework16_inputmodule (FW16) - same as inputmodule-control but is needed if you want to play and crontrol the built-in games in the led-matrix (call with ledmatrixctl or ledmatrixgui)

• framework_tool (FW13 and FW 16) - use to see and configure general things on your framework system. Commands using the embedded controller might not work, it looks like there are some problems with the kernel module used by the EC. Fixing this is out of scope for this hackweek but I am working on it

• qmk_hid (FW16) - a cli to configure the FW16 qmk keyboard. Sadly the gui for this is broken upstream so only the cli is usable for now

Build a split keyboard from scratch by mpagot

Description

I'm getting older... this summer I experienced an annoying and persistent tingling in one hand and arm. That was the initial motivation to get more interested in ergonomic work gadgets, and from that to split keyboards. And that was the entrance in a rabbit hole.

Which keyboard I like to create:

• Split keyboard for ergonomic (I'm not primary interested in having it portable)
• I have big hands: I like it to fit as much as possible my hands measures
• Columnar stagger keys position
• Not too few keys (at the moment I'm at 24 + 24)
• One row thumb cluster
• No wireless, not to have batteries and for security reason
• CherryMX, or generally speaking no low profile/corne choc
• Hot swap Socket switches

Goals

• Create PCB design for a split keyboard
• Get it produced
• Mount it
• Evaluate FWs

Resources

• Main project repo: Zenga
• ZKM config for a hand wired 4 keys something: nne
• Blog posts opensuse.hackweek.2024

Progress

Day1

Get the existing Ergogen project working on my TW machine Get Kicad as flatpack Go back to the https://flatfootfox.com/ergogen-part3-pcbs/ Join the #ergogen Discord channel and ask for help about the nets

Day2

Redesign the keyboard matrix on Inkscape Implement it in the Ergogen YAML format Create a Kicad PCB file Start routing it Iterate over the matrix arrangement to try to implement it like 2 layer board and ideally with not vias Get some Kicad tutorials

Day3

Get my hand dirty building a 2x2 key matrix --> welcome to nne Look at ZKM and how to configure it --> https://github.com/michelepagot/zmk-config-nne Get the FW built by github, try to flash it: get matrix scan pulse but no keys to the PC Get in contact with ceoloide, an Ergogen maintainer, about net issue.
