I’ve been using the ErgoDox Ez and I really like it but there are some layout changes I wanted to do. I held off doing it for a while because to change the layout you have to build an entire new firmware for it, which I wanted to dedicate enough time to completing successfully. In the end, once I had all the parts together and the new layout figured out, it took me 15-30 minutes to do. Using this guide I could probably do it in 5m, except for the changing the keymap file portion. That is a bit fiddly and also just requires thought about what you want to do. This should work on the ErgoDox, but I label this the Ez instructions because it uses the Ez default keymap.
- Decide on what changes you want to make and write them down. For example, I wanted to put grave accent where tab usually is, make the key left of “a” be Esc when tapped and Win when held, etc…
- Download the Teensy flash program from https://www.pjrc.com/teensy/loader_linux.html
- Set up the udev rules as mentioned in the above page.
sudo apt-get install gcc-avr avr-libc dfu-programmer
- Clone the https://github.com/jackhumbert/qmk_firmware repository:
git clone https://github.com/jackhumbert/qmk_firmware.git
- Go to the ErgoDox EZ directory:
- Make a directory for your keymap:
- Copy over default layout:
cp default/keymap.c mykeymap/
Changing ErgoDoc Ez Layout
- Modify mykeymap/keymap.c to adjust your layout. I was able to figure it out by looking at it, but if you need instructions look starting here: https://github.com/jackhumbert/qmk_firmware#switching-and-toggling-layers
- Build the new keymap:
- Copy the hex file to your directory:
cp ergodox_ez.hex keymaps/mykeymap
- Run the Teensy program:
- Press the recessed button through the hole in the upper right corner of the keyboard with a paperclip.
- Press the right arrow button and select the hex file you created.
- Press the down arrow to reboot the Teensy.
- Test the keyboard.
- Repeat this section until you are happy.
- “a” key: KC_A
- Win when held, Esc when tapped:
- Layer 1 when held, Grave accent when tapped:
- Switch to/from Layer 1:
- Switch to/from Layer 2:
- Control when held, “z” when tapped:
There is a GUI configurator at https://keyboard-configurator.massdrop.com/ext/ergodox that I didn’t use because I really want the keys that you can tap for one thing and hold for another, and I couldn’t see that it was supported there.
If you don’t want the keys that you, for example, tap to get “z” and hold to get Ctrl, then the Massdrop GUI configurator linked above may be the way to go. It gives you a hex file directly. I really wanted those dual use keys though. I really wanted to start with the default ErgoDox Ez layout and make a few changes, and this is the easiest way to do that.
I use the Windows key a lot for my window manager (i3wm), and the default layout had left Win on the thumb pad and the right Win on my pinky. That asymmetry for a modifier key was very hard to get used to. So I think I’d try to keep modifiers symmetric in the future.
I’ve been ripping some CDs for my mom. I had been using “ripperX”. It works fine, though it’s very manual. Insert CD, wait for CD to show up, click on “SCAN” wait for track info to show up, click on “LOOKUP” for CDDB information, eyeball CDDB info, click on “GO”.
My mom has a *LOT* of multi-artist CDs, where the track names are things like “Elvis Presley – Jailhouse Rock”, and ripperX doesn’t (that I know of) have anything to help put the artist information in there correctly, it’ll consider the artist “Various Artists” and the track name to be that as above.
However, there’s another ripping program called “jack”, that *WILL* do this correctly. *AND*, you can do neat things like “undo” the tagging/renaming, modify the CDDB information, and then re-apply the naming/tagging.
It’s a curses UI, so I can run it in a screen and access it remotely, for example. Here is my .jack3rc file, because this was fairly tricky to get right:
I run it as “jack –edit-freedb”, which scans the CD, does the freedb lookup, and then pops me into an editor to review and modify the CD information. Then when I save the file, it starts ripping.
I usually rip into the directory “/tmp/d”, and then once I’m happy with it I will move the resulting directory to my normal music storage directory. This allows me to do the undo/edit/redo commands on just a single disc without fuss.
So once you’ve done the rip, if the names aren’t right, you can do “jack -u” to undo the renaming. Then you can do “jack –edit-freedb” to modify the names and rename the files.
This is working REALLY well for ripping the multi-artist CDs.
I don’t know what jack does if the CD drive is ejected though. If it waits for the CD to be inserted, I could imagine a loop like “while true; do jack –edit-freedb; eject; sleep 1; done”.
Then you just need to build one of these:
