DIY MacroPad

Project Introduction

Embarking on this project was initially a fun way for me to learn KiCad and 3D modeling. I also saw a great opportunity to integrate this macropad into the custom desk I'm building. As my friends started inquiring about what I was working on, I realized the potential demand for such a device. Crafting it myself and writing the code turned out to be not only more economical but also allowed for greater customization and refinement compared to existing software solutions, which I found limited and lacking in refinement.

Utilizing AI Assistance

Throughout the project, when challenges arose or I found myself stuck, I turned to ChatGPT for guidance and troubleshooting advice. This support proved invaluable in navigating the complexities of the software components.

Development Progress

Currently, I am still in the process of enhancing the software and ironing out some kinks in the PCB design. As a learning endeavor, I anticipate making some mistakes, but each error provides a valuable lesson. The software handling the serial communication and macro conversion is developed in Python, using PyQT for the GUI, while the ESP32's firmware is created with the Arduino IDE.

Design Goals and Aesthetics

I plan to continually update the code and refine the enclosure design. My goal is to achieve a look close to the 3D model I've designed, ideally using metal for the enclosure and acrylic for the top cover to diffuse the LEDs, creating an aesthetically pleasing light effect.

Manufacturing and Adaptability

Currently, the enclosure is being produced with a 3D printer, which is what I have available. However, the versatile nature of the software I've developed is a significant advantage—it can interface with any device that outputs serial data, making it adaptable for a range of applications. This flexibility allows users to assign specific macros to unique serial outputs from various devices, enhancing the utility and applicability of the macropad in numerous scenarios.

Community Engagement and Support

For more details, updates, or if you have any questions or issues, you are always welcome to check the project's GitHub repository. There, you can also report any issues or engage with the community and myself directly. This ongoing dialogue helps refine and evolve the project continuously.
