ur an insane person but i like your style
Thanks, I guess? :P
That's awesome!
Now I really want to replicate something similar in a future keyboard I build.
Thanks! :)
the readme says that your firmware enables pullups on clock and data lines but i don't see that code in your keymap?
Yes, you're right, I changed the PIO driver directly for that: https://github.com/joh/qmk_firmware/commit/aa0214f5b1b3001cf7cc99419c32c8b87707cb5a
I plan to make it an optional feature for qmk proper, but for now it's somewhat of a hack :)
What are you using for left/ right /middle click?
I'm using the thumb cluster keys.
I wanted something like this! I think I'm gonna give this a shot, thank you for sharing your work
Cool! Let me know how it goes :D
This is marvellous. Thank you. I will save this link and make my own!
Thanks! Let me know how it goes :)
Super nice!
How much did you pay for the trackpoint and shipping? It's great to hear that you can just email Sprintek!
Nice that the RP2040 doesn't require a reset circuit! I just finished a handwired with a ATMega32U4 ProMicro where I needed to remove a resistor to clear the D5 pin for USART. That was quite a painful process overall. This seems significantly easier!
Thanks! I paid $28.55 per SK8707 module + shipping (around $22 to Norway).
Ok, I gæs it'd be about the same shipping to Denmark. Compared to sourcing from ThinkPad keyboards, I find it very appealing to not have to risk popping the pin pads of the pcb when desoldering the keyboard ribbon cable. I've caused a few casualties.
Edit: Ah, I see you had to undsolder a ribbon cable from the controller board, too.
You don't have to desolder the ribbon cable. You could use some sort of ribbon cable connector, if you have one available. But I found it more practical to only have the wires I needed. And desoldering the ribbon cable was fairly straightforward.
Amazing thing that my ADHD ass wants to replicate with my piantor but will never have the time to.
Thanks, full time job! /s
The piantor looks like a nice piece of kit! Unfortunately the PCB doesn't seem to have any holes to accommodate a trackpoint. There even seems to be a trace right between the YUHJ keys, so drilling a hole is not possible either.
i need this
