The “flipping” is handled mostly internally. For The right hand side, the firmware just maps the rows and columns differently than for the left hand side. For pins where this is not possible (Vcc, Gnd,…), there are jumpers on the other side that need to be soldered.
The main lesson I learned was probably to start thinking “in hardware” and not software. Like you design something and it fits on paper but in reality, it might not be ideal. For example, my diode placement is very close to the hotswapsocket (i fixed that for rev 1.1). On paper it war fitting, but its kinda hard to solder when you need room for your solder iron in between - this is something kicad won’t tell you.
Thanks. I must admit I am curious to see what mistakes I’ve made this coming weekend. My first KiCAD PCBs should arrive this week, then the penny shall drop I suspect.
If you’ve not tried it yet I’d recommend having a go at reflow soldering with a hot plate. It makes some aspects of assembly easier.
I haven’t yet had a chance to get two rotary encoders working under ZMK yet either. Did you have a good resource to use for that or did you need to figure it out yourself?
There is a zmk pull request open that adds split encoder support. If you use that to build your firmware if should work.
To be honest I have not tried it with this board so technically one scrollwheel is not working right now. Though I’ll change that soon. I used a fork that supports split encoder with zmk on my sofle and it worked, so you could use this config for some inspiration (here: github.com/dnlbauer/sofle-zmk-config).
Great work, looks like it could be a commercial product. I’m still not sure if I want choc V1 or V2, but if I go with V1, this might very well be the build I copy.
yeah they are a bit expensive. But they are worth it imho. Scrolling with the thumb on them feels very natural and the height is very similar to the chocs!
That’s because of scalpers, they aren’t produced anymore alas. Someone on the Reddit mentioned wanting to make an alternative to that scroll wheel but I don’t know if it went farther than just designs maybe.
That’s a beast! Looks great. The scroll wheels make a lot more sense to me than the inspirational ones you linked to in the github that have knobs near the thumbs. Course I guess the knobs are intended for the thumb and maybe scroll wheel would be pointer finger. Scroll wheel looks better imo.
I use my thumbs for the scrollwheels. My previous build was a sofle but the knobs always bothered me. They stick out too much, make it hard to transport the keyboard and I got into a habit of turning them with my thumb+index, so leaving the home row. With the wheels, using them feels much more natural!
Haven’t tried regular-sized choc switches before, but they should work. One thing to consider would be that with the heigher switches, the scroll wheel might be harder to reach with the thumb because it might be physically hidden behind enter/space. Should not be a problem if you are used to use the index for the wheels though.
