Title: Okey65 ortholinear keyboard
Post by: kiks64 on Thu, 03 February 2022, 19:41:11
Hi there !
You don't know me because I'm not an active member and I haven't posted for years, but let me introduce you to Okey65, my ortholinear keyboard which is the evolution of my hand-wired keyboard that I been using for several years.

It features one more column than the Preonic and an atypical layout.
It consists of a pcb with the classic atmega32u4 and a usb type C connector, 2 plates of fr4 and an SLA resin frame, fully dampened by EVA foam.
I put Gateron Pro Milky Yellow switches in it and reused my dsa keyset from Signature Plastics, and I'm very happy with the result, apart from the lock key indicator LEDs that don't work.

If you want to know more and maybe build your own https://github.com/kiks64/OKey65 (https://github.com/kiks64/OKey65) but keep in mind this is my first electronic design  :)

Very cool. Don't know if I've ever seen a 13 column ortho before.

I use a 14 column (split 5x7s).
Don't think I could get used to 12 columns. This might be a good option.

Thanks for posting and showing off your wonderful project.

Thank you for your interest !
Indeed I designed it because I was very interested in the Preonic but it lacked a few keys.

Nice keyboard!! I like the classic feel of the case!

Is it something physically wrong with the pcb that the led isn't working or the qmk code is not correct to work right?

I've done a little work with led indicators.
If it's code, I might be able to help.
Let me know if you want to continue here, Pm, or on another platform. I find discord or similar easy for quick responses back & forth.

Thank you for your help  :)
From what I understand wiring is not complicated, an LED assigned to a pin of the chip with a resistor in series (150ohms in my case) and connected to ground. I checked that the pins of the chip are well soldered, and I found that the voltage is almost zero (0.6V) when the key is locked.
Regarding the code, I generated it on kbfirmware.com since my understanding of the firmware is very limited, so I chose the simplest solution. I simply assigned the pins corresponding to the indicator LEDs.
I leave you the choice of where to chat, it's already very nice to help me!

is it a standard, single color led or an RGB led?
- if a standard led.... what is the voltage it's rated for? also, different colors will run at different voltages. blue or white leds usually requiring the highest voltage out of the single color leds. look back to where you bought the led from, should have a voltage mentioned.

standard led
[attach=1]

RGB led
[attach=2]

and each of these is handled differently in the code.

Update : The indicator LEDs issue is fixed by rewriting the firmware with the official QMK environment instead of using the kbfirmware.com configurator.
Thanks to nevin for his help  :thumb:

YAY!
Congrats friend. Glad you got it working and managed to compile from source.

...you've now entered the realm of "knowing"..  lol.
