While I love to jump on the anti-Elon bus, I have to query: the highest accident rates, or highest accident rates as a percentage of vehicles on the road? If you have 10 Tesla cars on the road, and there are 2 MGs on the road, and 2 Telsas and one MG crashes, then what? 20% of Tesla vs. 50% of MG, but also that could be framed as ‘double the number of Teslas crash compared to MGs’ or ‘Tesla has the highest accident rate of any auto brand’.

It’s running on 2x BlackPills, with hotswap sunset orange switches. The two halves are connected by an ultra thin CAT6 patch cable. It’s the first keyboard I’ve built with backlights, so quite happy that it worked as planned.

The 2x OLED displays are still a work in progress

Hi all,

I'm hoping for some troubleshooting tips. I have a self-build split keyboard using Blackpills.

If I flash either side with 'SPLIT_KEYBOARD = no' in my rules.mk, then both sides work fine (but both working as the left side). If however I set 'SPLIT_KEYBOARD = yes', then both sides stop working.

It's driving me insane!

These are the relevant details of rules.mk:

MCU = STM32F401
BOOTLOADER = stm32-dfu
SPLIT_KEYBOARD = yes
SERIAL_DRIVER = usart

And config.h:

#pragma once
#define HAL_USE_SERIAL TRUE
#define SOFT_SERIAL_PIN A12
#define MASTER_LEFT
#define MATRIX_ROWS 6
#define MATRIX_COLS 6
#define SERIAL_USART_DRIVER SD1
#define SERIAL_USART_TX_PAL_MODE 7

And halconf.h:

#pragma once
#define SERIAL_USB_BUFFERS_SIZE 256
#include_next 

And mcuconf.h:

#pragma once
#include_next 
#undef STM32_SERIAL_USE_USART1
#define STM32_SERIAL_USE_USART1 TRUE

Please help! I've been at this for three days.

The challenge is that these days a phone is rarely used for calls or texts, but used with apps like WhatsApp or Teams or Slack or your mobile banking app, or things like that. And so there would need to be a critical mass of these apps to get me to switch.

I created a 2d surface that I can perform a linear extrusion on, however the result it obviously a hard edge on the extrusion. I would love to be able to add a bezel - either rounded or at 45 degrees. Is there an easy way?

I’ve got the basics down, but now looking to do something more complex, and unsure if it’s possible. I have imported a flat shape (a pcb), and I can extrude this out. What I want to do however is to rotate it on its axis, and then extrude it down the z-axis (not directly out from the surface). Is this possible, and if so, how?

I’ve just cancelled my Medium subscription. I was finding myself going there less and less. So many articles saying the same thing in various levels of broken English.

Is there such a thing as an online pcb tester? As in ‘here is my pcb design, when I connect this, I expect it to register as a circuit on these two pins’

Hey there,

Hoping someone could point me to a PCB that is using a Blackpill and a ST7789V OLED display. I have the above and am not 100% on which pins to wire up. GND is obvious. VCC I’m pointing to 3.3V, then there is:

  • CS
  • DC
  • Reset
  • SDA
  • SCL

The smaller screens only have SDA & SCL. Can anyone confirm whether the others are optional, mandatory, whether there are specific/preferred pins?

I’m feeling a little lost at the moment, so hoping for some guidance.

FYI this is the specific display: here

Hi all,

TL/DR: Ergo Split 36-key with per-key RGB and 2x 2 inch TFT screens, run by 2x BlackPill. Can QMK handle this?

I'm hoping someone can sanity check this for me before I go printing a PCB only to find there is no software capable of doing what I want without major code involvement.

My plan is for a split ergo keyboard with 36 keys (6 rows of 3 per hand, including the thumb cluster). Each key would have an SK6812-MINI-E RGB backlight, and would be run off a BlackPill controller in both sides. I was going to make the connection using a CAT6 patch cable, understanding I don't need all 8 of the cables, but also that a patch cable clicks into place so a reduced chance of shorting anything by disconnecting the sides while still powered.

The gotcha is that I want to run 2x 2" OLED displays, one on each side. Specifically, they are the ST7789V GMT020-02 from Shenzhen GoldenMorning Electronic Co.,Ltd via AliExpress. I know that QMK has Quantum Painter LVGL Integration, and this should support a display. But can I run two independently of one another, one driven off the first BlackPill and the other off the second?

Feedback would be greatly appreciated on this! I have all of the hardware, other than the PCB and case. Before I spend too much time designing the PCB, I want to at least hear that it should be possible, as opposed to hearing that for a variety of reasons it's an absolute non-starter.

I think it gives everyone the same list of 29, but it’s the order that’s important. Gentoo came back as my top. I use Void which came back as 4th in my list.

[-] nydas@lemmy.world 3 points 1 year ago

Well at least at the end of the questions the distro I use (Void) was somewhere near the top of the list (4th).

If you use hotswap, you’ll need something solid and immovable to mount those hotswaps to. That’s generally the pcb, as they both slot in and get soldered on. So you’d need to have a pcb with hotswaps that could work on a Dactyl, and a way to mount it so that is was stable and would take the pressure of pushing in a new switch.

Amoeba Kings is a per key pcb. I have one I built in my git that is choc spaced with RGB too. But you then have to solder each of these together, and attach them firmly to the case. So it would certainly be more work/effort/planning than simply hand wiring.

Where a comment has been made on my post, it would be awesome to see which post it was related to. It helps give context when there are 15 replies to 5 different posts since I last checked.

Moore's law is the observation that the number of transistors in an integrated circuit (IC) doubles about every two years.

Is there anything similar for the sophistication of AI, or AGI in particular?

I’ve never been much of a musical person. But my kid was playing with a toy piano the other day, pressing buttons and whatnot. I lay my fingers on the keyboard and thought “hmmm… kinda like the home row”.

So my question to the community: have any of you built musical keyboards? Did you post a blog or guide? At first I was thinking a choc switch with a custom long cap that was held off a pivot point at one end and attached to the switch at the other. But musical keyboards vary sound depending on how you press the note. So maybe Hall effect?

Anyway, keen to hear of any adventures down this road by others?

True. I think someone else pointed this out as well. But I don’t eat a poultry drumstick. The English language is a funny thing!

[-] nydas@lemmy.world 16 points 1 year ago

Fascinating! Thank you all for the answers! I got an F in French at high school, which might explain why I hadn’t made the connection.

When I eat chicken, I call it chicken. Chicken wing; chicken drumsticks etc.

When I eat lamb, I call it lamb. Lamb shank; lamb cutlets.

So why do I not eat pig or cow? I eat pork or beef. Is there a reason for that?

In fairness I can predict with a fairly high degree of accuracy that the majority of relationships will fail. If I were to take a random Facebook user who updated their status to ‘in a relationship’ and said that the relationship wouldn’t be successful, I’d likely have a 99%+ success rate.
