Current one I soldered myself, but the cheap iron I got from Amazon does not get hot enough on the smallest tip to allow me to solder the lights, so for now it's not backlit. Also one of the keys fails every once in a while even though everything is soldered correctly, I think it's the controller, LPT if you have a split keyboard with an TRRS cable, don't unplug the TRRS while the keyboard is plugged, apparently that can cause power surges, which I only read after doing that, and starting getting that error with that key.... Luckily I planned ahead and have the chip built on a plug, so all I have to do is buy a replacement and solder the pins, but since most of the time it works I keep forgetting about it.
I have four custom keebs. The first three I soldered myself. My current home one is this:
My work one is prebuilt. I tried to solder it myself and may go back and fix the boards I have but I was so baked I put the lights on upside down, all of them.
3rd party MJF printed, but then i handwired and soldered the 6x5 orthosplit.
Get solid core wire and prepare to debug. But hey, you learn your Keyboard back to front. It's good feeling afterwards :) also knowing you can fix it no matter what.
I soldered a Planck kit, then an Iris v2 kit, then bought a recent Iris with hot swap and all that jazz when the first started acting up and I couldn’t figure out why.
I want to start actually making stuff - really interested in a Dactyl-like contoured board - and I have most of the stuff I would need for the electronics side of things, maybe upgrade the cheap soldering iron. The one thing holding me back is cases. With kids and a dog, I’m honestly not too interested in leaving bare electronics sitting on my desk. I want a pretty case too, and that mostly means 3D printing. I never had any room for a printer, and online printing costs were pretty prohibitive in my area last I checked.
The whole spectrum: First a bought a pre-built board, then had a friend build one for me. Finally, I got over my fear of solder, bought the inexpensive equipment and gave it a tried. Made one $10 mistake on the first try and did a good-enough job on the second try.
I look forward to fixing more things now that I have this skill. I already used it to help repair an e-bike connector that came loose.
All the boards I currently rotate between (3 at this time) have factory soldered hotswap sockets. I haven't done much soldering myself, none on keyboards in particular. For PCBs that come assembled or unassembled I prefer to pay a bit more for assembled because it's generally not a huge difference. Unfortunately some don't offer that option.
I have a solderable PCB of one of the first custom boards I got a few years back and I still haven't gotten to building it - I couldn't commit to a specific switch, the PCB doesn't support soldering hotswap sockets, and adding millmax ones seemed too much of a hassle. Moreover at one point they announced they'll supply hotswap PCBs, so I'm probably going that route.
I got a Keeb.io kit and soldered it myself, and then I've handwired a Dactyl Manuform and (halfway) a Splaytyl. I love how many people can build you a 3d-printed keyboard these days, but I'm already equipped and experienced to do it all myself.
