Hey everyone,

I’ve spent a lot of time thinking about how to bring the sci-fi fantasy of a digital card arena into the real world, but in a way that actually fits how people play in local shops today. Most wearable duel disk props are heavy, loud, and ruin expensive cards.

So I came up with an open-source, smartphone-grade hardware ecosystem called Project Monolith :

The Launcher: A heavy, pocket-sized anodized aluminum deck box that automatically scans card-sleeve margins and ballistically deals cards across the table.

The Smart Mat: A standard-looking neoprene mat with embedded micro-electromagnets. When a card flies out, the mat grips a thin metal stripe built into the sleeve edge, snapping it flat instantly so it won't slide or flip.

The Screen: No heavy VR or AR glasses. You just put both players' phones side-by-side in the middle of the table to act as a split-screen "Digivice-style" matrix for animations, life points, and battles.

The best part? It works with almost any TCG or board game.…
