I made a mistake while ordering the parts for the Ferris Sweep: I only ordered one 301230 battery. I ordered the other one, but the >1 month delivery time is a bit long. I am wondering if it is possible to solder and build the keyboard now, while only installing battery in one of the sides, and use the only side only with USB-C. If yes, I have two more questions:
- Which side should I install the battery in? From my understanding, one of the sides usually works as a “hub” for the other side
- Is it easy to add the battery to a already assembled keyboard in the future?
- Are there any good tutorials for assembling the wireless variant of the Ferris Sweep? I have mostly been able to find resources for the wired versions.
Yeah, I would recommend using the “central” (master) side as the one plugged in, the “peripheral” (slave) side should last at least a month on one charge and will talk wirelessly to the central half. By default with the Sweep ZMK firmware the central is the left and peripheral is the right.
Socket your controllers, not least because they’re expensive and it’s nice to reuse them in future if you get a different keyboard rather than buying more, but also because it’ll make installing new batteries easier. Don’t forget the power switches.
Good luck with the build.
