Re: Help me with recomendations
I'll start worrying when (not if; when...) chat-GPT becomes aware that it's shameful to be identified as such, and dumbs itself down to the level of the average, illiterate human bean. Problem with LLMs (i.e. also ChatGPT) is that they lie in about 20% of the cases. They do it with a great confiden...

I found out that ordering keycaps on aliexpress works very well for good prices, No custom hassle when delivered to EU. But you may not be able to get the fancy stuff. No fancy Signature Plastics caps.

Re: Software-less programmable keyboards
If it is this one then it uses ATmega32U2 without external EEPROM. That means 1024 B of internal EEPROM and only 32 kB FLASH. Not really usable. At most 450 keys in macros if you are really lucky.

Re: Software-less programmable keyboards
I use that firmware with ATxMega. It works fine. Many new (mostly ARM based) MCUs do not have any EEPROM. It is not a big deal. They have a lot of FLASH. And you can store to FLASH. It is just much more code to handle FLASH storage and sometimes(*) when you have hard realtime requirements it may be ...

Re: Software-less programmable keyboards
You need to have enough EEPROM available to implement it easily. Many MCUs do not have it. Some have it but small amount: e.g. Atmega32u has only 1 kB. One remap map will take about 110 bytes which leaves you about 900 bytes for macros after some bytes are used for config data. So you are left with ...

Re: Looking for keyboard/touch typing advice.
You can learn both. Provided both keyboard have almost the same layout, e.g. both are more or less qwerty but one is row staggered and the second one is column staggered then most of your skills will be transferable (i.e. which key is pressed with which finger). You will not forget the old layout if...

I do not use them. You will get slightly weaker joints by cutting threads into acrylic or by using wood crews into softer plastic (e.g. ABS) without threads (wood screws will cut it's own thread).

If damaged then try to fix it (reconnect the trace, replace the part, ...). If it looks OK everywhere then you may have caused an electrostatic damage. This typic...

You should clean everything and if the traces are not physically damaged then re-flowing the solder should be enough. If yo...

Re: How important is programmability to you?
I have a custom keyboard so I do not use remapping much. I already defined the base layout the way I want it. I use macros somewhat: e.g. MacroShift-G does vim-grep on the word under cursor, MacroShift-R repeats the rename of the next tree item in my CAD, etc. Not an absolute necessity but very usef...

Browns are tactile but not clicky. Blues are tactile and clicky. Both are fine as far as I'm concerned.
I tried to use Gateron whites (i.e. blacks with a weaker spring) but I was not impressed.

Overall, switches are less important than the keyboard shape, layout and firmware.

Your trigger setup you have shown is correct now. Yes, the last switch has issues. It may not be critical. Valid CMOS levels are 1/3 of the Vdd. If the signals do not drop by more than 1/3 then it will not glitch yet. Anyway, I would replace the switch. It will likely get only worse as the switch is...

4k7 resistor is ok as well. You only want any low voltage setup which leads to currents of around 0.1 - 1 mA. Not too high voltage, not too high current since keyboard switches are low voltage and low current. If your probes have switchable attenuation then set it to 10x. It has higher bandwidth tha...
