Welcome to tecsmith.design
About
On this site you will find Silvino Rodrigues’ custom keyboard and home automation device designs.
The intent here is one of education. My hope is that you will be inspired to create your own electronics and embeded software products.
All my personal (non-commissioned) projects will be hosted here (or rather on Github).
The tools currently used are:
- EAGLE CAD, for electronics schematics and PCB design
- VSCode
- with QMK, for keyboard firmware builds
- with PlatformIO, for automation firmware builds
- Fusion 360, for case design
