*Note: this is a hackboard, not a hackpad

This is a 75% keyboard inspired by the Keychron Q1 Custom Keyboard. It consists of 82 keys, hot-swappable switches a 3D printable case, and stabilizers. The bottom half is split in half to make it easier to sand

I primarily started this for HackPad v2. However, during the process of making this, I learned more about the different types of switches, stabilizers, splitting up CAD designs into multiple parts, and all the parts of the keyboard. I learned a little bit more about the Arduino Keyboard library, how to write relatively efficient code, and organize my pcb schematic and pcb in a larger scale than what I previously learned. As I had taken a break for a few months from my original keyboard design, I had stopped
