Can you make a video to explain USB HID Power Devices, preferably using stm32 bluepill?

I think beyond the atmega328, stm32s are cheaper and easier to work with. I think you should also mention JLCPCBs standard parts library which which is LCSC parts but includes all the capacitors and resistors, so someone can possibly get all surface mount components assembled for very cheap. STM32F103C8T6 with some parallel in serial out shift registers I think is the best option as compared to getting a microcontroller with a GPIO pin per button. You can also configure the shift registers to clock and send data on interrupts and use hardly any of the processing time, while still getting update rates >200hz. Nicely made video though.

is there a reason why only a ground plane was filled and not one for VBUS and the like?

Couple of remarks 1. Kicad is now at version 8, you used ancient version 6.0. In 8 you do not need to export any netlist manually, it is being automatically tracked 2. USB-C shield should be connected to GND, not left floating, usb-c cables will connect GND to shield anyways (not sure if all of them) 3. Kicad has at least 3 plugins that can automatically generate gerbers to specific manufacturers, I personally use Fabrication Toolkit 4. For repeated layout like you have there is a plugin named "Replicate layout" which can make sure that diodes are perfectly aligned to every key (as long as you keep in hierarchical sheet)

WHAT A TUTORIAL

19.05mm is exactly 3/4 inches.

4:49 error in video. Matrix is never shown

last time? You mean the vid you uploaded a year ago?

I was going to make one then decide I don't want something that dangerous in my room

Eagle is better than kicad. has the autorouting which kicad clone does not have.

I taught it was a video about tiny tapeout or home made silicon. This is really bad clickbait.

There's a far easier way to get the schematic to the PCB. In the PCB editor, top center, there's a button that says "Update PCB from schematic"

😂

You should update your link to your tindie, fyi. your dot dev domain link is dead.

Great guide, love that you stepped through and explained key combinations as you went through the whole process, bookmarking this for whenever I take the kicad dive from other paid softwares. Something you skipped over is setting trace widths, and you're using class defaults(though you did talk about it for the diff pairs). I would thicken all traces to switches, there's no reason to make them thin like high-speed data paths. If anything that little bit of extra trace capacitance, could help mitigate some switch debounce on occasion, but mostly for robustness. Also adding 'teardrops' features onto on all PTH and vias is a good thing to do as well, helps gradient the mechanical stress of hitting keys into a larger area so traces are less prone to hairline cracks developing right beside vias and large pad interconnects.

I’m going to use mini usb

Can you do a video about how to build pcb for beginners

Hey there. What a great and informative video, especially for KiCad beginners! I have some quick tips I thought I could mention (maybe you already know): 1. Might be good to make a habit of assigning nets to net classes. This way, you can assign different track widths for different nets/netclasses. 2. I often forget, but setting the fab's capabilities/tolerance values to the design rules before beginning routing. The KiCad defaults I believe should be okay with JLCPCB 2-layer values, but sometimes I forget and have to re-route many parts of my board. 3. You don't have to export and import netlists in KiCad. In the PCB editor toolbar, there's a button that will pull in the netlist from the schematic directly. This is also handy if you make changes in the schematic as you work on the PCB and want to apply the changes. 4. For keyboard layouts, I found the "Keyboard footprints placer" plugin to be really useful. Should be in the default kicad plugin repo. You can define the layout you want in json (or use keyboard-layout-editor .com) and it will lay out the switch+diode footprints for you in the desired layout. And then you can group/lock the switch footprints so that they stay together. Regarding length/impedance matching and differential routing the USB lines, you shouldn't *really* need them for something like this, but it was very nice to see it mentioned in there (also demonstrating the usage of the built-in calculator). Cool video!

Subbed with alerts. Thank you.

Ahh, a fellow fan of KDE.

Great video again! Can you recommend any resources for larger switch matrix layouts? I want to make a full sized 109 key keyboard, plus some macro keys, but all the resources I've seen so far are for smaller 70%/80% boards. There's probably some clever way to handle the matrix where matrix columns cover multiple columns of keys of something, but without guidance I'll be reinventing the wheel.

I highly suggest you look into KiCAD hierarchal schematic design practices when using multiple sheets! It’s a far more elegant way to use multiple sheets and more ‘safe’ than using global labels everywhere.

Yes i don't understand why and how they are still manufacturing things with microusb. Do they have like a literal ton of those connectors just laying around that they hope to use up?

Can you try to make a mouse that will be awesome

Awesome video! Also, really good kicad skills and tips. Looking forward for the next one.

how did you get dark mode lcsc?

Oh my days, I learned more about kicad than I ever learned about it than other videos

I've waited a year for this video lol. In the meantime, I made two hand wired keyboards using a RPi Pico as the microcontroller.

How to change Kicad GUI to dark mode

I was expecting to get some garbage again when youtube recommended me a video with 2K views but I was very wrong. I've thought about how hard it would be to make a fully custom ergonomics focused keyboard, since all the commercial ones are still extremely expensive to the point were making it custom probably isn't significantly more expensive. This explained stuff super well and made the subject seem much more approachable!

For the wiring, I would recommend using the freerouting kicad plugin which does about 90% of the wiring for you.

If you understand this video you can make PCBs already and don't need it. And if not - there is far too much stuff NOT covered here...

This absolutely makes PCBs seem way easier than i thought they were.

Great video ! I hope to watch part 3 soon !

thanks for uploading it....some of us have been waiting for this for a year !!

what he actually made part 2!

Part two is out now!!!!!! ruclips.net/video/fYNxG8RwpaE/видео.html

Can you do it on xbox one controller?

Do u have insta. I need help with this

I need one for my Xbox one controller

The people looking for this type of video don't know what an asic is, and those that do expected you to make silicon chip like other youtubers have. Maybe "I built a computer circuit at home" would be better?

But that thing in a rc plane lol

* WARNING A SENTRY BUSTER HAS ENTERED THE AERA*

Cool video, but what is with the title?

*uncle dane theme *

Why is it not working? Because its a f*cking Toyota man 😂😂😂😂

How do you drive many LEDs from a USB port? I have 92 SK6812 Mini-E LEDs on my keyboard, and currently I'm just trying to see if running them at low power is bright enough to fit within the limtis of a USB port. I'm also thinking I can plug into a Thunderbolt 4 port for mor power, or maybe do something in the software to stagger the PWM so that only half of them are on at a time.

Why step motor, is'nt servo better ? I am building similar system it should tracking live target instantly
