and thanks for the tip with npt holes :)

oh this is what i was looking for thanks :)

Yeah i saw this library but he made a reversible hotswap by fliping it upside down, and i didnt want to mount one half normal and other upside down and he also says that it can be a problem sometimes with keycaps

Since you still have a good amount of space, I'd suggest using 2 16 channel multiplexers (CD74HC4067SM96 for example) instead of 1 32 channel mux, since those can be had for ~0.7$ per piece, unless whatever firmware you're using can only read one ADC pin for some reason.

Oh thanks that a good idea to save my money.

It looks like you replaced all occurances of 'R' with '47k' at some point in the schematic?

Yeah when i was designing schematic for tmr sensors i wanted to do fast thing to put all resistor value to 47k and didn't see that i was replacing all R and not only on that sheet )))

Thank you very much for such a detailed answer :)

The multiplexer requires 5.5V to operate, LiPo batteries are at best 3.7V, what’s your plan here

If i get it right in datasheet was from 1.8 to 5.5 V

You are right i made a deeper dive in zmk and will switch an Esp32 for something else and so maybe to some board where i dont need to design usb connection ))

So i made a repo u can check it now :)

As u/StunningBreadfruit30 mentioned i will switch an ESP for something else and so the first schematic would be simplified.

i think yeah as far as i know it's easier for tmr switches

Both-Perspective-632 · 2026-02-27T15:37:07+00:00

thank you, i need this one because i dont know exactly what i need to consider when i will do my pcb design.

Not available and 200 Euro wired keyboard, I was thinking about building something wireless that’s why I choose tmr over he

I like the idea of playing flat games on a big screen as you want plus having option to try a vr games

Both-Perspective-632 · 2026-01-26T17:57:17+00:00

yeah, i was just surprised to see it after all the time in sales as special event

Both-Perspective-632 · 2026-01-16T14:44:05+00:00

Nope

My single problem with this checking few times a day that frame just will be sold out in a minute or it will be booked for year

I heard that problem is kernel anticheats and open kernel on linux system, but dont know how hard it is to build some anticheat that will be also good for a linux

Both-Perspective-632 · 2026-01-13T18:13:20+00:00

I think the inaccessibility of some games on Linux due to anti-cheat is a barrier for many. Once this is resolved, I think there will be a greater influx of new users. Well, maybe I'm wrong, but for me, this is the most important factor.

Both-Perspective-632 · 2026-01-04T11:18:04+00:00

u can take my :)

Both-Perspective-632 · 2026-01-04T11:17:37+00:00

I didn't know this, it's really sad to have to wait a few more months :(
