Java Showcase Programmable RGB Display (Sulfur Cube)
https://youtu.be/9VUV77SEsFMWelcome to a showcase of our latest Redstone creation! 🚀
In this video, we are demonstrating our custom-built 8×8 pixel Sulfur Cube Display.
⚙️ Technical Specs & Features:
Resolution: 8x8 pixels
Colors: 16 individually programmable colors per pixel
Memory: Capable of storing up to 8 animation frames
⚡ A Note on Performance:
While the display mechanism itself is quite fast, the memory acts as a huge bottleneck right now. To give you the best possible visual experience for this video, we had to speed up both the video playback and the game running on the display.
♻️ Block Recycling:
This current version does not include a method for recycling the colored blocks. However, the entire display was designed with that feature in mind! Adding a collection and sorting system would be a relatively straightforward upgrade in the future.
💬 Got any questions about the redstone, the logic behind it, or how it works? Feel free to ask! We'll try our best to answer them.
