I made Ace of Sharks a four wheel drive robot! I modified a wheel hub from Printables to have a pulley for a belt on it, but Fusion did not like working with a mesh converted to a solid and I could not finish it. So I had to start over with Fingertech twist hubs (files free on their website) and added the pulley to the twist part of the twist hubs. When I was making the belt, I was doing a bunch of math to get the size and it turned out way too big. Then I realized the number I calculated was the circumference and I was using it as the diameter. That fixed it! Next, I will need to print out the parts and see what problems I missed in the CAD.

I made more room in the back of the robot for pinewood derby car weights (to make the robot drive better on two wheels) then changed the robot to have four wheels (which eliminates the need for the weights). I modified the washer part of a wheel hub on Printables to have a pulley for a belt to drive the front wheels from the back wheels. The file imported into Fusion way bigger than it should have been, which made me do it over twice when I realized. Found an Amazon listing for shoulder bolts which will be axels for the front wheels. I also modified the front attachments to touch the floor with the new wheels.

Moved the PCB edge to flush with the edge of the USB-C port, added the corresponding hole in the case, and added some text to the case. I also began the compiling process and ran into a whole bunch of errors and missed semicolons…
In the code that I am testing, all but one of the errors is fixed! I don’t understand the correct syntax for switching layers, and code in a different file is a ‘statement with no effect.’

Coded all the keys for the macropad! It is my first time coding in C, so we’ll see how many semicolons I missed later… I used several other tutorials that were not linked to in Hack Club guides.
Setting up QMK: “How to Build a Handwired Keyboard” by Joe Scotto, starting around 12 minutes in (youtube.com/watch?v=hjml-K-pV4E).
Layers: (keebsforall.com/blogs/mechanical-keyboards-101/how-to-add-layers-in-qmk).
Macros: (getreuer.info/posts/keyboards/macros/index.html#simple-macros).

Designed the case for the macropad in Autodesk Fusion. Not sure what the cutout should be for the rotary encoder or LED, so I may need to change that if I figure out a better guess. Discovered Lapse for tracking time (lapse.hackclub.com), which made it much easier to track total time spent, including time looking at tutorials.

Spent two untracked hours trying to understand the given guide before realizing that Hackatime was not linked and fixing that issue (github.com/hackclub/kicad-wakatime/tree/main). Found a different guide to making mechanical keyboard PCBs with KiCAD that was way easier to follow (youtube.com/watch?v=8WXpGTIbxlQ) and got this made! I am not sure how close the edge of the PCB should be to the USB-C port on the XIAO, so I may adjust that later. Other than that, I think the PCB is finished!
