OK, I do not care that much about switches. I think the overall keyboard shape and the layout are more important but some people do care about switches a lot and this may be interesting to them:

Interesting. Application notes I read recommended to place EMI and ESD protection (diodes and low pass filters) as close to the source as possible (i.e. near the edge of PCB where signal enters). Only power distribution network requires also decoupling capacitors and those should be as near to the M...

Almost all electronic parts have EDS protection built in up to 2 kV at least. Human body model. I doubt you need more.
As for as ussage: do not touch the metal parts of the keyboard USB connector when you suspect you may be charged. Touch a ground wire of your electrical outlet first.

Actually, 10 points for switches and 10 points for a layout have some value. Keycaps have some value as well ... probably not full 10 points ... but still ...

Unsplit: -1000 Horizontally staggered: -1000 Flat: -10 No thumb keys: -50 MX mount: -100 Less than 2mm travel: -500 +1 Ergonomics is completely missing for the KeebScore. It is a score which needs to be introduced so that we can somehow differentiate keyboards which are already almost the same anyw...

Which firmware to use? Chris' firmware: https://github.com/chrisandreae/keyboard-firmware or my branch of it: https://github.com/hercek/keyboard-firmware Features: Almost no community. Chris did respond to my questions when I had any. I can respond to questions about my branch. Uses LUFA or vusb (s...

Interesting.
How many photos were used for one scan?

An European company must ship it to you without VAT. You will pay price without VAT at the time of ordering. If here are any import duties for keyboards in USA then you will be paying them when the keyboard arrives to USA. There is no VAT in USA so you will not pay any VAT but import duties may be a...

If you send only one pulse to a piezo-buzzer then it sounds a bit like a click. It is rather silent though.

So, my pc chassis should be connected to earth through the 3 pin plug. Yes, that is protection by grounding. It is required by law ... probably in about every country. Should I expect the exterior of the usb ports (== the shielding ground, as I understand it) to have continuity with the chassis? Ye...

In other words: if your keyboard requires a shielding ground to be connected to anything then you are likely having some other problem which this connection somehow mitigates. An example is a poor connection on the signal ground.

There are two grounds on an USB connector: Signal ground. This must be connected to the MCU ground . Shielding ground - this should be connected to the shielding of your keyboard case if it has any shielding at all. Most cases do not have any shielding (e.g. because they are plastic). In such case, ...

Well, maybe people do not use it because there are more comfortable alternatives and even cheaper ones (definitely when you want to make it from $20 teensy). But you can go with ProMicro for $4 and a bit of soldering, firmware burning and rather awkward waveform extraction. Or you can buy $6 Saleae ...

FreeCAD is quite usable. Considerably slower than commercial alternatives though. By slower I mean that there is still too much manual work which could be done automatically by the program (e.g. it does not guess the right constrains when drawing sketches). Also the OpenCascade (on which FreeCAD is ...

...different layouts that you want on different layers... The problem is that language-layout is interpreted by the host, not the keyboard. That is only a problem if one cannot get a generic super set of all layouts working. Like Compose key or unicode hex input. Then you can issue any key using th...

Not without a a custom driver. You can write some macro which will do it for you or an application which will switch the layout after some special input (e.g. on F13). And you can use something like Compose key or Unicode hex input to simulate changing layouts. Compose key support is native in linux...

You did not say which Teensy it is. Different versions have different MCUs. Anyway I drive a piezo buzzer directly from an MCU pin and it works ok. I'm still using only about 1/3 of the pin current capacity. Compute the maximum current your buzzer will need and if you are bellow the pin current rati...

Splitting space bar is a move in the right direction!

The arrow key is the best!

@Findecanor: Fair enough. The conformability limitation would not matter much for me but it may matter for others. To tell the truth it is definitely not a keyboard for me . Not because of conformability (despite my keyboard being on the fly configurable without a host application) but because it is...

The keyboard works with all operating systems, but every configurable option has to be changed in the "Wootility" program. Nothing is configurable on the keyboard itself. The program is for Windows, macOS and Linux but 64-bit x86 only. If the configuration is saved into the keyboard and the keyboar...

I just wish they made these in a full case instead of floating switches and had integrated stuff loaded in the keyboard instead of having an external program running.

Does not not work without special drivers?
Does it work on mac or linux?

Nice.
Well, we still need a programmable force curve to get an ultimate keyboard switch

It is very likely you cannot do this for Manuform without redesigning the keywell or making the case bigger. Notice that you need one row of keys almost in plane to fan-out flexible PCB columns from. You either need such a row of keys or you need a bigger case to place the row of PCB connections out...

spongebob1981: I thought you meant it for every keyboard, not only for enthusiasts' keycap sets. But there is not much difference in reasoning except the price. It costs about a buck when a part of a keybaord and from 15 up when sold separately. And the lower price range will not have any non-US leg...

spongebob1981: That it never going to happen. Production keycap prices are in cents and you want increase that price few times. And what about environmental aspect of this. Most keyboard users would be throwing away a lot of keycaps they do not use. It is not only eñes, çedillas, carons, ... It is a...

The compose key: I'm astonished it never found its way into Windows as it's so useful for doing stuff like this on any keyboard without needing to know arcane and obscure control codes. A friend using windows reported that this works well (at least on Win10 ... and probably on older versions as wel...

I preferred ansi to iso when I used a standard layout. Most keyboards use iso here.

The reason was simple. I used enter more often than backslash.

I heard about using palms for the bottom row keys at the sides. You are probably not alone using it that way. That is using palms on still quite small Ctrl keys. To be honest I have palm keys as well (used as layer shifts). But I never smash them, they are small and it is a custom build, i.e. not co...

Ask a piano player

I talked to tp4tissue on geekhack. He is a piano player and loves to move hands a lot around keyboard. I need some time to recover from the stress of that experience
