Hi folks, I've been working on this keyboard pretty much since January of this year, and I've finally got it to the point that I can call it done! If you'd like to build one, all files are available here.
This is an MX-based keyboard, 36 keys with integrated trackball. The github page has a bunch more details. I also have a choc version in dev using the same style that's based off the Trinidox.
What is the difference between the MX and the choc version? If I understand correctly, chocs also fit in the 14x14 mm plate holes that the MXs need. And since you're hand-wiring, there is no PCB with different holes. Shouldn't the chocs just fit the MX version?
You're totally right. The thickness of the key matrix could have been 2mm for choc (instead of 4mm for MX), and I bet there's a way to combine the recesses for the difference in key switch grippers.The spacing between keys in a column can be 2mm closer for choc (key cap difference), meaning the choc keys in an MX board would have an extra 2mm between keys (more reaching, gasp!). Unfortunate, but doable.
The deal breaker for me was the position of the trackball. A choc key is much lower than an MX key, meaning a choc on the MX would lead to reaching up to the trackball. I found that quite uncomfortable. I actually had a trackball placement somewhat like that during dev and used it for a week...I injured a tendon in my thumb and had go back to another board for a while, hehe. Trackball placement is finicky.
Sorry I might not be understanding this correctly, but does that mean the choc version will have proper choc spacing and be 2mm closer? And a properly located trackpad on top of that?
That is exactly what I've been waiting for. I printed the case for a MX Skeletyl but found the spacing a bit too far, and the choc skeletyl that I printed felt a bit off for some reason.
They keys within the columns are spaced as tightly together as I could get them without interference. The column to column has more space though - I just found it more comfy as I ran through some iterations. But now I'm getting curious about smashing the columns together again...I think the keyboard could be considerably smaller. I'll release this version and continue to mess around...I'm just working through some annoying under-extrusion issues on my printer, so I'm hoping that I can have it released in a couple weeks.
