Building hardware projects is often quite challenging, largely because the field is dominated by expensive, proprietary software typically only present in the arsenal of large companies. Thankfully, the rise of open-source software has changed the game, making hardware development accessible to a much wider audience. In this presentation, I'll share how I have leveraged some FOSS projects to create innovative open hardware.

We'll delve into the hurdles of hardware development and how I have utilised a mix of well-known and lesser-known open-source tools to aid in my project to develop a fully open-source, RP2040-based, QMK-compatible 3x3 mechanical macropad. Here's a brief overview of what I'll discuss:

1. KiCad, the leading open-source tool for PCB design
2. QMK, the open-source firmware powering mechanical keyboards
3. PrusaSlicer, is essential for preparing your 3D printing files
4. FreeCAD, RP2040, and several other hardware essentials

And that's just scratching the surface.

This talk aims to highlight how you can effectively use popular FOSS projects for real-world hardware product design and development. I hope to inspire and ignite creative ideas for your innovative projects.
