Did I miss it?

Is there any advantage to using separate MCU pins for each key instead od diode matrix?

Are there any major advantages to assigning each key its own pin on the micro controller? Like key press latency etc, and is there anything else you need to think about that you wouldn’t when using a matrix? I want to make a small gaming keyboard with only a few keys, and I want to have individually addressable LEDs per key. Obviously a matrix would reduce the number of pins I need, but I’m interested in the potential for the latency save somewhat?

Hello! Why do you have 2 or more switches in the same place?

wow this is really neat! i'm trying to build something like this and need your help because i'm only 14 and new to making stuff like this. I was wondering if you could help me and jump on a call with me please if you can consider it.

going through this process myself and dropping the matrix for the higher io chip was brilliant! I was wondering how much did the pcbs cost in the end and where did you go to manufacture these?

Hey could you do this but basically how to make a keyboard pcb for dummies?

All I can see it cats. You should disable their display. Plus too much zooming in and out.

Can I ask, how did you program the keyboard? Was it through DFU USB or through the SWD pins?

Hi KoBuss, I've been following your build guides and they've been really helpful for making a case of my own! Can I ask what size standoffs and screws you used to assemble your case? Thanks!

I would like to see a video on how you programmed the arm controller

I subscribed coz cattttoooo

I’m trying to make a keyboard business and I need to find out how to design a keyboard so I can patent it but I’m somewhat lost because I would like to make a modified 65% and I don’t know how to make 3D models for the case and pcb, and I’m still trying to figure out if I would also have to make my own type of switches so I don’t run into legal issues? I’m not too sure yet about that tho

Is there a cheap and easy way to make just the frame to the case, and not the entire case, because I already have a case but no frame to hide the "feet" of the switch.

What company produced the PCB? Did you get the ST soldered by them?

How would I make this into something with a wireless chip and Bluetooth?

what operating system are you using in this video?

Im currently making my own pcb and there are some connections that I'm not sure of, so I'm trying to find some on github that are using the same MC as me, but I don't know how to convert the code into schematics that I can view.

how long you make this 3d?

Hey, what's a good replacement for the MCU that you used?

an individual pin for each key that's new

Hey man what paltform or supplier you used to create this keyboard

I couldn't find the BOM file in your GitHub, please help

how much does something like this cost to print?

Iam also making the exact same keyboard but I want to add led between switches. Could anyone please explain where to connect led switches

yea q

with multiple layout configurations, you mean that in one section you have different positions for keys, where they could also be offset by half a centimeter? So if you don‘t want that, it should be quite straight forward, right?

Hey little late to the party, I'm looking into making diode-less keyboard with QMK support. I do not see STM32F072V8T6 on the list of compatible microcontroller for QMK. I just wanna confirm if STM32F072V8T6 actually support QMK and have you tested with it? As I'm quite new to this any input would be amazing! Thanks in advance

This reaaaaaaallly makes me want to make my own custom keyboard D: like custom, custom. self-designed PCB, self-designed case & plate.... ahhhhhhhhhhhhhhhhhh damn. I should never have watched this video :'( goodbye wallet & time

amazing video, i want to try and make my own keyboard, just one question the keyboard 3d model, which one do you use?

how did you make the key switches on your schematic?

kicad gives me error opening schema file. Does not appear to be an eeschema file. There is no solution in any forum, need help pls.

really cool diodeless approach, not often you see someone moving such a mature technology forward like this!

how much would it cost for create a test unit ?

How would you route data and power lines for addressable led, would it require a separate layer?

The reset “button” can just be a resistor and when you need to reset, bridge the resistor with a pair of tweezers

Thank you so much for making these videos. I’ve been wanting to design my own board!

Why use a 32 bit controller?

hi for some reason trying to load the project in kicad isnt working i think because im using v5.1.10

Would the process be a lot different if I’m designing a macro num pad with an lcd and Rotary dial?

Can you integrate an hub usb?

Great video! Thanks for sharing all this knowledge!

13:25 - it’s a bit frustrating that the data sheet only supplies metric values for a couple of items. I suspect these things were designed in metric. Because 14.000mm (specifying extra precision just to emphasize that I mean exactly 14mm) lands within the 0.551+/-0.002” (14mm=0.551181”), and for the plate thickness you’re talking about here, 0.06+/-0.004 may be close to 1/16” (0.0625”), but 1.5mm is closer (0.0590551). (And even 1.6mm, a common nominal PCB thickness, is within spec. And gets even closer without the copper layers. (However, outside tolerances for such a PCB, especially with copper, may exceed allowed tolerances for the keys, so... YMMV.)

your audio is way too low, besides that great vid

Very nice tutorial. I like the workflow between this open source apps :p!

u/neoarmstrongcyclon

u/mexsistor Your videos are very clear and straight to the point. Keep it up ✌🏼
