@@lmapa69 Don't be afraid to solder! I remember I used to not go for solder only boards when I first started and I missed out on some great local group buys.
Awesome build! Taeha I noticed you don't lube the wire on your TX stabs. Does that ever cause tick? I just used TX stabs for the first time and used xht-bdz on the wire but now am questioning if I needed to!
Great stream! One quick note, the original Sonnet that you are using was an old prototype that was not used for production (hence the different screw size). Anyone with an original Sonnet and new Sonnet will have the same screw hole sizes.
Wireless would make it very hard to develop the firmware. Either you have to stick with ZMK, which many people will not be familiar with, or you'll need to tweak QMK to a VERY deep level.
