If you build a hotswap trackpoint and would like to share it, please add a single comment to this issue (and edit the comment with updates rather than adding a new comment). Provide a summary of the keyboard, trackpoint, and firmware used, any changes made, and links to any published build details or firmware changes.

I did it waaay back there in 2019. Also wrote that T60 can be cut in half to the size of Pro Micro.

Keyboard: crkbd Trackpoint: R61

Firmware: Initially used @manna-harbour's just for debugging the trackpoint.

# right
sudo make crkbd:manna-harbour:dfu-split-right MH_MODULE=trackpoint MH_AUTO_BUTTONS=yes LTO_ENABLE=yes MH_DEBUG=yes
# left
sudo make crkbd:manna-harbour:dfu-split-left MH_MODULE=oled MH_DEBUG=yes LTO_ENABLE=yes OLED_ENABLE=yes

My current firmware (WIP) is at rfong/shibui.

Build logs:

• Part 1: sourcing & disassembling the module. No real procedural changes from crkbd hotswap trackpoint doc, but lots of pictures & tips.
• Part 2: physical assembly, mounting, wiring. Was short on space because I use taller headers on my keyboard controllers and I didn't have any surface mount components, so I rearranged the driver wiring so that the stripboard plugs in over the TRRS jack.

Trackpoint module currently faces left but the mount placement was done a bit hastily. Will probably move it down to align with home row and bring it in closer when I redo the acrylic cover.

Hi,

I'm in the middle of planning an "embedded" trackpoint controller board support to my variation on crkbd. I've added the driver board electronics as SMT components similarly to the buzzard and would like to connect the controller board to the PCB to the right of the thumb cluster (increase the right side PCB just a little bit). This way I won't have to play around with too much rewiring (I think).

However, I'm unsure how to actually connect the controller board to the keyboard PCB. I thought of soldering right angle pins over the pads between the controller board and sensor module, this way I could at least socket the controller board. I'm just afraid it would be too flimsy and hard to solder.

Do you have any suggestions?

Thanks

Not strictly a "hotswap trackpoint build", but very much inspired by it so thought I'd share it here :)
