Hi all, I am retronexus!
I run my own workshop where retro consoles, vintage computers, and modern gear all get a second chance. Some of my work includes:- Restoring Amigas, Commodores, and other classic systems
- Modding and repairing Nintendo Switches, GPUs, and consoles
- Designing custom PCBs and replacement pads for chips, HDMI connectors, and fragile SMD footprints
- Building 3D-printed jigs and fixtures to make tricky repairs repeatable
I’m also a bit of a systems junkie: I containerize my infrastructure in Docker, manage my brand ecosystem across GitHub, Nextcloud, and WordPress, and I’m obsessive about design systems — from SCSS token maps to Figma components.
When I’m not repairing, I’m usually sitting in a plane flying.
If it’s got circuits, software, or a story, I’m probably in. Glad to be here and looking forward to contributing.Comment
