charybdis-pmw-3360-sensor-pcb VS Charybdis

Trackball requires a trackball sensor breakout board. I have my own breakout board that I offer, but I also tested with the charybdis sensor pcb ( https://github.com/Bastardkb/charybdis-pmw-3360-sensor-pcb )

soldering of two Charybdis Trackball PCBs (I don't think I can convince u/FMcraft to sell me two assembled ones solo without a whole kit).

Unfortunately yes. I'm going to remove the sensor breakout board and try it with a different mcu just in case, but I highly suspect that my sensor (or the breakout board is at fault.

At the same time (when it's ready... still have to do build guides and finish firmware) I will open source the 3d files like on the rest of m designs. The whole thing is made to be handwired, but does require a few PCBs to make your life easier: a custom PMW3360 sensor PCB, and an elite-C shield including a connector for the sensor PCB.

By the way I had time to test the PCB - works well. Here's a link to the github https://github.com/Bastardkb/charybdis-pmw-3360-sensor-pcb

I am using https://github.com/Bastardkb/Charybdis/tree/main/files/mods/tenting-stand-with-wrist-pads With the Gelpads from Ali. And are quite happy with them. Interestingly do they change after a while and don’t snap to each others, but that’s not a problem.

yep what he said. check this out https://github.com/Bastardkb/Charybdis/blob/main/files/mods/readme.md

I started my split journey by building a dactyl manuform with amoeba king pcbs. Now I use a charybdis nano because it has an integrated trackball :D

I use a Bastard Keyboard Charybdis Nano. It's an ergo 3x5 keyboard with built in trackball. I built it myself but you can get them pre built too.

Most of my free time is spent researching and engineering for various open source projects. I also enjoy building custom keyboards, right now I'm rocking a Bastard Keyboards Charybdis that I hand built myself. Fun facts: I'm left handed and used to train and ride horses competitively.

Stumbled upon this keyboard while searching for Dactyl Manuform pcbs. Thought I'd share it here as well.. Also its open source : https://github.com/Bastardkb/charybdis Bastardkb website : https://bastardkb.com/charybdis/

The design is not mine to share, but it is fully open source -- one of the reasons I really respect bastardkb and wanted to build this board. You can find the files (and license) on the bastardkb github.
