kint VS ferris

I can suggest the following, I had three advantage 2s before picking up my 360pro.

I modded all of the 2s with the following boards:

* https://github.com/kinx-project/kint - Great board, requires usb of course. Programmable with QMK.

* https://github.com/wizarddata/Blue-Wizard-Mod - Doesn't support QMK but does support ZMK but is bluetooth. Great board.

I picked the kint up on some pcbway type service, the blue wizard I got off ebay.

Is Stapelberg's Kint with a Blackpill the suggested approach nowadays?

I have a KinT board in my Advantage2 keyboards, gives you all the QMK goodness.

I assumed you tried using the link for kinesis_kint41_default.hex from https://github.com/kinx-project/kint/tree/main/default-firmware and it did not work. It is difficult to download individual files from github if the file is not text.

Some time ago, I replaced the default SmartSet controller board by a KinT board (produced by JLCPCB) with a Teensy LC controller to run QMK. It's splendid and I like it so much more than the default SmartSet firmware. Also makes it easier to keep the 360 Pro and the Advantage2 in sync.

You mean Stapelberg's own Kint? It's also great, I use it in two KA2s (only not my work KA2).

The original Ferris keayboard uses an I/O expander.

So, I know the Ferris repo is here: https://github.com/pierrechevalier83/ferris

For minimizing awkward finger movements, I feel like a decent approach would be to borrow techniques from the tiny keyboard crowd make a multi-layered keyboard layout to minimize movement. e.g. some people have 34 key keyboards with multiple layers triggered in various ways to get the full range of input. (Some people go even further, e.g. to 16 keys).

I have 3 equipped white PCBs for Ferris Compact v0.2.1. It's a 34-key ergo keyboard, for Kailh Choc switches.

The base idea is something like this amazing keeb but with a more aggressive pinky row stagger like the ferris

With this principle in mind I tried somehow to create my modifier layout, if you want to check out my keymap&x:10%3B&=Pause%0A(enc)%3B&@_y:1.25&x:3%3B&=*&_x:9%3B&=%2F=%3B&@_y:-0.75&x:2%3B&=%25&_x:1%3B&=+&_x:7%3B&=-&_x:1%3B&=%5E%3B&@_y:-0.8700000000000001&x:5%3B&=%2F@&_x:5%3B&=%2F&%3B&@_y:-0.6299999999999999%3B&=Esc%0A%60%0A%0A%0A%0A%0A%0A%0A%0A%0A~&=%23&_x:13%3B&=$&=%5C%3B&@_y:-0.75&x:3%3B&=%3C&_x:9%3B&=%3E%3B&@_y:-0.75&x:2%3B&=%5B&_x:1%3B&=(&_x:7%3B&=)&_x:1%3B&=%5D%3B&@_y:-0.8700000000000001&x:5%3B&=%2F%2F&_x:5%3B&=%5C%3B&@_y:-0.629999999999999%3B&=Tab&=%7B&_x:13%3B&=%7D&='%3B&@_y:-0.75&x:3%3B&=!&_x:9%3B&=%3F%3B&@_y:-0.75&x:2%3B&='&_x:1%3B&=%2F:&_x:7%3B&=%2F%3B&_x:1%3B&=%22%3B&@_y:-0.8699999999999992&x:5%3B&=,&_x:5%3B&=.%3B&@_y:-0.6300000000000008%3B&=Shift&=%7C&_x:13%3B&=%2F&=Ctrl%3B&@_y:-0.5&x:2.5%3B&=Mute%0A(enc)&_x:10%3B&=Pause%0A(enc)%3B&@_y:1&x:3%3B&=3&_x:9%3B&=8%3B&@_y:-0.75&x:2%3B&=2&_x:1%3B&=4&_x:7%3B&=7&_x:1%3B&=9%3B&@_y:-0.8699999999999992&x:5%3B&=5&_x:5%3B&=6%3B&@_y:-0.6300000000000008%3B&=Esc%0A%60%0A%0A%0A%0A%0A%0A%0A%0A%0A~&=1&_x:13%3B&=0&=%5C%3B&@_y:-0.75&x:3%3B&=Up&_x:9%3B&=5%3B&@_y:-0.75&x:2%3B&=Left&_x:1%3B&=Right&_x:7%3B&=4&_x:1%3B&=6%3B&@_y:-0.8699999999999992&x:5&a:7%3B&=&_x:5&a:4%3B&=0%3B&@_y:-0.6300000000000008%3B&=Tab&=Tab&_x:13&a:7%3B&=&_a:4%3B&='%3B&@_y:-0.75&x:3%3B&=Bottom&_x:9%3B&=2%3B&@_y:-0.75&x:2&a:7%3B&=&_x:1%3B&=&_x:7&a:4%3B&=1&_x:1%3B&=3%3B&@_y:-0.8699999999999992&x:5&a:7%3B&=&_x:5%3B&=%3B&@_y:-0.6300000000000008&a:4%3B&=Shift&_a:7%3B&=&_x:13%3B&=&_a:4%3B&=Ctrl%3B&@_y:-0.5&x:2.5%3B&=Mute%0A(enc)&_x:10%3B&=Pause%0A(enc)%3B&@_rx:4&ry:8.175&y:-4.675000000000001&x:-0.5%3B&=Tab%3B&@_y:4.5&x:-0.5%3B&=Tab%3B&@_y:4.25&x:-0.5%3B&=Tab%3B&@_rx:13&y:-4.675000000000001&x:-0.5%3B&=Alt%3B&@_y:4.5&x:-0.5%3B&=Alt%3B&@_y:4.25&x:-0.5%3B&=Alt%3B&@_r:15&rx:4&y:-4.675000000000001&x:-0.5%3B&=Ctrl%3B&@_ry:13.75&y:-4.75&x:-0.5%3B&=Ctrl%3B&@_ry:19&y:-4.75&x:-0.5%3B&=Ctrl%3B&@_r:30&ry:8.175&y:-5.675000000000001&x:-0.5%3B&=Esc%0A%60%0A%0A%0A%0A%0A%0A%0A%0A%0A~%3B&@_x:-0.5%3B&=Shift%3B&@_ry:13.75&y:-5.75&x:-0.5%3B&=Esc%0A%60%0A%0A%0A%0A%0A%0A%0A%0A%0A~%3B&@_x:-0.5%3B&=Shift%3B&@_ry:19&y:-5.75&x:-0.5%3B&=Esc%0A%60%0A%0A%0A%0A%0A%0A%0A%0A%0A~%3B&@_x:-0.5%3B&=Shift%3B&@_r:45&ry:8.175&y:-5.675000000000001&x:-0.5&h:2%3B&=Space%0ALower%3B&@_ry:13.75&y:-5.75&x:-0.5&c=%23949494&t=%23000000%0A%23080808&h:2%3B&=%0ALower%3B&@_ry:19&y:-5.75&x:-0.5&c=%23cccccc&t=%23000000&h:2%3B&=Space%0ALower%3B&@_r:-45&rx:13&ry:8.175&y:-5.675000000000001&x:-0.5&h:2%3B&=Return%0ARaise%3B&@_ry:13.75&y:-5.75&x:-0.5&h:2%3B&=Return%0ARaise%3B&@_ry:19&y:-5.75&x:-0.5&c=%23949494&h:2%3B&=%0ARaise%3B&@_r:-30&ry:8.175&y:-5.675000000000001&x:-0.5&c=%23cccccc%3B&=Gui%3B&@_x:-0.5%3B&=Back%0A%0A%0A%0A%0A%0A%0A%0A%0ASpace%3B&@_ry:13.75&y:-5.75&x:-0.5%3B&=Gui%3B&@_x:-0.5%3B&=Back%0A%0A%0A%0A%0A%0A%0A%0A%0ASpace%3B&@_ry:19&y:-5.75&x:-0.5%3B&=Gui%3B&@_x:-0.5%3B&=Back%0A%0A%0A%0A%0A%0A%0A%0A%0ASpace%3B&@_r:-15&ry:8.175&y:-4.675000000000001&x:-0.5%3B&=Delete%3B&@_ry:13.75&y:-4.75&x:-0.5%3B&=Delete%3B&@_ry:19&y:-4.75&x:-0.5%3B&=Delete) (and maybe share any thought's on it)(no function layer yet, work in progress)(I'm eventually gonna build a Ferris and I feel like 6x3 is too much for me, so my layers are 5x3), please do.

I would be very interested in having a programmable ergo keyboard like the Ferris: https://github.com/pierrechevalier83/ferris

The ferris (not sweep) is a great example of a board with an integrated mcu. The big disadvantage is that the design is tied to a specific part and also will be less accessible for DIYers. In the case of the ferris, the chip that it uses has been almost impossible to find for the last year, which is one of the factors of the sweep's popularity over the ferris. https://github.com/pierrechevalier83/ferris
