Keyboard from scratch (school project)

Recommended Posts

Posted (edited) · Original PosterOP

Well hello there

 

This is the start of a keyboard build. The basic premise of the keyboard is to do a slight update of the modern QWERTY keyboard so that regular users (such as myself) can adapt to it while gaining the benefits of the updates.

The keyboard is to be targeted towards a specific group of PC users which is not determined yet but it is likely to be towards either CAD users or gamers

One of the updates i missed when i did regular work was delete and enter closer to the left hand. But exact placement is to be found after a short study of key usage, separate thread here:

https://linustechtips.com/main/topic/1244953-keylogger-to-map-out-most-used-keys/

 

I have access to laser cutter, mills, lathes and 3D printers and more, so this is mostly a planning, organizing, CAD and time issue. And money.. ish.

 

 

Here is just some older ideas.

Haha. Because I am going to use it and i like my keyboard to be relatable(and have all the keys) so that it becomes less pain to use other keyboards and my laptops.

 

There is many reasons to keep QWERTY layout and do small updates, familiarity and customers willing to try it out is one of them.

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

 

Spoiler

 

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

 

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

 

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

 

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

 

Personal Blacklisted Companies:

Spoiler

Acer monitors, Gigabyte, Seagate HDD, Kingston SSD, Razer (except their mouse), XiaoMi Phones

 

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

Switches. I am thinking a type of Cherry switch. or MX speed switches. But i kinda want them to collapse too to get that tactile feel.

I also dislike travel after actuation. I guess that can be fixed with a O-rings but idk. Feels like a patch for a problem that should not exist.

Switches need a tolerance range and a bit of hysteresis. If they only would only make at the very end of their movement it makes them more prone to failure, tolerances could be out from the factory or due to wear over time. Plus with certain switch types the physical mechanism itself may need to cycle or go through a physical action like popping, clicking, bouncing etc. between states or when making/breaking.

 

I'm talking more generally here across switches such as industrial switches I work with, AFAIK they always make or break before physically bottoming out or reaching the end of their travel. I opened up a small momentary limit/tamper switch and to give it a snappy changeover and tactile feel it had a pretty intricate little mechanism. With larger industrial switches like limit switches they are designed to have overtravel and generally may be damaged by bottoming out, so between actuation and the over travel gives you a region for a mechanical stop to be apllied with looser tolerances and yet still function correctly.

This seems to state overtravel as deliberate to allow for fast partial keypresses without having to bottom out constantly.

 

https://www.cherrymx.de/en/mx-original/mx-black.html

 

So if you look at the cherry in action there could be issues with the design as is if the overtravel was too low.

 

Not saying it isn't doable just there are reasons to have a bit of overtravel or actuation before bottoming out, usually it is a good thing or there is reasons behind it, especially with mechanical switches at least.

Where do i actually buy the switches? is there a full kit for 100+ keys?

 

Edit: Done. Went with MX red silents. As for overtravel argument it seems silly to need o-rings that is all.

 

I kinda wanted to try speed switches but did not find a online shop for it.

Imo thread is put into wrong sub forum. Hobby electronics is a small part of this project.

 

Having said that does anyone recommend a spesific chip to wire all this up?
