Aurora Corne PCB (comes with diodes and choc hotswap sockets to be soldered)
2 Nice!nano v2 USB-C controllers
2 batteries 301230 3.7V 110mAh
Kaihl Choc low profile Orange switches.
Choc keycaps
Carbon fiber plate
Case (I have not bought any, I've just made a wooden panel, cutting it ad hoc), but I may buy one in the future or 3D print one, let me know what you think about it.
About the building process, I can say that I was afraid of soldering, but it was fun and easier than expected. I struggled a little more with the firmware configuration, because I was used to QMK but the nice!nano controller uses ZMK so it was a little different.
After configuring my Colemak layout and my layers on the firmware, the flashing process is pretty strait forward. Also the bluetooth connection integrated in the nice!nano was connected easily to my PC.
However, after 1 month of use, I have started feeling some issues in the left part of the keyboard, mainly with modifiers, such as Ctrl, Shift, Alt, and some letters. When I keep them pressed they are not recognized and I have to repress them. I don't think it is a firmware issue, because I have tried different configurations in ZMK and now all of them fail with the same keys, independently of whatever character I map on those keys. I am thinking that it maybe due to some diode that may be missoldered or some pin in the controller, because the first days it worked fine. And I have tested the same configuration as those days, and now I am getting these issues.
I do not use it for gamming, so I cannot answer that, but maybe you can use only the left part and the mouse for shooter games. I would need to remap AWSD because I use Colemak layout or maybe use another layer to move to Qwerty.
However, I use it everyday for working as IT consultant, I don't do programming really often anymore, but I don't have problems typing numbers or special characters (;,[]/<>...). In fact, you just need to memorize where they are and the layer, but your fingers move much less than in a full size keyboard.
I use it daily in my work (sysadmin). Not for gaming - but you could just create a gaming layer with the keys needed for that.
I do some scripting in my work, and it works ok for that. But some coding languages might need a different layout.
