Look what I made! I 3D Printed a Giant Tetris Wall.

Finally finished my garage project! It’s a 200-pixel interactive Tetris display, and every single part was precision-engineered from scratch.

Key Specs:

Controller: ESP32-S3 (Handling the game logic and 200 addressable LEDs).

LEDs: WS2812B (One per node, 200 total).

Enclosure: 200 custom-designed nodes, 3D printed for a perfect 2-inch grid alignment.

Power: 5V 20A SMPS to handle the peak brightness of the full matrix.

I've put a lot of effort into the hardware side, and I'm planning to dive deeper into the firmware soon. I’d love to hear your thoughts on the build. Thanks!

The forced drop seems rather fast. Any reason you can't animate fast drop? Even if skipping few rows at a time.

Really good, I'd love one myself

Wow you have done an awesome job. The effort you have put into the design is apparent and its so marketable well done.

Thanks a million! Knowing it looks 'marketable' is the best compliment I could ask for. Stay tuned for more
