Cadpad

Built and created the Cadpad! After waiting for what felt like way too long for everything to arrive, I got everything and built the design. Soldering was a bit tricky, but I got it all done.

QMK code finally compiled. Hopefully when I get to flashing it will work. I spent a lot of time sorting through the compiling errors that I was being given, many of which did not make sense, but seemed to resolve themselves when other issues were fixed. After a few hours, I was able to get the code set up for the encoders and special tap dance features compiled, and hopefully functional.

QMK troubles: I began creating the code for the cadpad and hit my first issue when the output was a .hex file rather than the .uf2 needed, I figured out that this was due to the controller or bootloader not being supported by uf2. I tried to create a new one to set my own configuration. However, when I tried to compile it, I got a bunch of errors that I still haven’t solved (File errors such as missing keyboard name). I have also read much of the documentation to figure out how to implement tap dance, and encoders to make the most use out of the cadpad. While I am not done, progress is moving.

Starting QMK code, I have never used QMK before, and I was really confused when the guide to set it up was seemingly not working, turns out it just takes a long time. I’m still not sure exactly what I am doing, but I hope that trial and error and maybe a few tutorials will get me there in the end.

Updating 3D models for the Cadpad, added a cool decal on the top, and fixed some errors that I had with the PCB, and collisions between the case. I had some trouble with KiCad exports causing some errors, but they ended up being non-critical. Also made sure that the PCB is very versatile, implementing a dual SMD and THT footprint so that if I want to learn how to solder some SMD components, I will have a great way to practice and get another cadpad! (Makes a great gift)

Refining the 3D Models, I made a few revisions to the PCB earlier to ensure it fits the switches nicely, which required me to update the 3d models, I also took the time to refine them and get close to a final candidate. I also think that a great use for the rotary encoder for cad will be to implement it for arrow key navigation. Since its a dual layer numpad / macropad, using the knob for text navigation gives the Cadpad even more features!

Learned a bit into KiCad footprint editing, my plan is to make a footprint that supports 2 major keyswitch types, Choc and MX style. The hope for this is to be able to not have the 5 PCBs in a typical MOQ to go to waste. So far it looks good, I had some trouble with the initial Choc footprint not lining up, as well as clearance under the SEEED XIAO, but a few tweaks were able to get me into CAD to see how the switches fit.

Initial Planning: My first devblog, I am experimenting with ways to make the PCB more reliable, since I dont want the other 4 from the set of 5 to go to waste! I am not sure if this will eventually turn out into something usable, but willing to try.
