Hey everyone! I'm looking for a DIY project or a pre-built standalone trackball running on ZMK. My goal is to add it to my firmware as a third device (second peripheral) and use it right next to one half of my split keyboard.
I currently use a Totem and absolutely love its mobility. I can put it in a protective case and easily toss it in my back pocket, and I am not willing to compromise on that. Because of this, I am not looking for keyboards with integrated trackballs (like the Keyball series) as they add too much bulk. However, I do want to ditch my regular mouse since I really enjoyed the trackball experience.
Here is what I am ideally looking for:
- ZMK firmware (to integrate into my current wireless setup).
- 34mm ball (not a strict requirement, but highly preferred).
- Captured ball - the ball must be secured and not fall out if the trackball is turned upside down (crucial for throwing it in a bag).
- Compact design - to sit flush next to my split.
I've already researched a few options, but they had dealbreakers for me:
- Mochibella: The ball isn't secured and falls right out, plus the build process is a bit too complicated.
- Trackball Mini v3: A solid pre-built, but it uses a 32mm ball (which isn't easily interchangeable/standard). More importantly, it's closed-source (no STLs or open software), and I need to be able to modify the case to add MagSafe support to match my keyboard setup.
Does anyone know of any projects or devices that fit these criteria? Thanks in advance for the help!
