I'm not sure but I don't think optical switches have that ability either, you're either breaking the beam or you aren't.
Wooting uses hall-effect sensors and MX-compatible "switches" that have a magnet in the plunger. The set and reset thresholds can be set in software/firmware.
So it can be done with hall-effect switches but not with mechanical switches as you say.
Ergos can be actually relatively cheap. That's why I've spent god-knows how much and have like 30 of them.
It's a nonsensical statement to us programmers too.
Does your keyboard have asymmetric halves? The left having 7 columns and the right having 6? As the other commenter pointed out you have defined 6 columns but your layout macro in eiris.h has 7 elements for the left hand. I think the way to solve it is to define it as 7 columns, add NO_PIN to the end of MATRIX_COL_PINS_RIGHT and then just add XXX to the end of all the rows for the right half in your layout macro in eiris.h.
This is outlined in the documentation
You might want to have a browse of !ergomechkeyboards@lemmy.world as well as the subreddit. Within that budget the best bet is likely something DIY. Though there is a middle ground with vendors offering build services and kits that are hot-swappable, turning "building" into "assembling".
Have a look at some popular choices and lists likes in the EMK wiki that I put together.
Generally yes, for keyboards without a number row we will tend to use some combination of those kinds of tricks. In the past I've had numbers on the homerow under an fn key (note that said fn key is on a thumb key so easier to press than the standard location for fn keys on regular keyboards). Currently I have a number row as vertical combos on my Sweep (34 key low profile split). So q+a = 1, w+s = 2, and so on. As well as a numpad on one half under a fn key (we call these layers). So for long strings of numbers I use the numpad layer, for short ones I use my "virtual number row".
However, I got here gradually, my first split was a keebio Iris (which has a number row) and have gone progressively in the direction of smaller ones. There are a good number of numrow inclusive splits out there. Some examples:
Splitkb.com is due to release the Elora (Kyria, but with a number row) Any Day Now™️
On foot pedals, I have a stack of them but haven't got around to making use of them in any projects yet. Others have
Most of the time it's not exactly useful and some of the positions are awkward (e.g. 8, 9, 10), counting to 31 on one hand is maybe useful.
More useful IMO is counting in base 6 and treating each hand as a single digit. i.e counting to 35 on 2 hands without awkward fingerings. Better than 10, less awkward than binary.
Even with AI models that can identify that there are birds in the picture. Having it decide with accuracy that the picture is of a bird is still a hard problem.
I agree, I'm just answering the why question. Free software licenses don't have non-commercial clauses and they want an NC clause.
I presume the reason they didn't use GPL3 is because they wanted the attribution and non-commercial clauses offered by CC-BY-NC.
Not suggesting that they should not prefer to drop those clauses in favour of a copyleft free software licence. but you asked "why not" and losing those clauses is clearly an obvious candidate for why they might not want to.
Ideally you want to use QMK's tri_layer feature as I outlined in this comment.
Also you can just use the _______ keycode instead of restating MO(...) on every layer as that is the an alias for KC_TRANSPARENT meaning it maintains the function of the layer below.
For this you need an analogue sensing mechanism such as hall-effect sensors (as Wooting use). You can see some open-source reference designs for PCBs, Firmware, and switches using hall-effect sensors on riskable's github to get you started. Technically you should be able to make a PCB like this and then use the same "switches" that Wooting use, though idk where they source them.
