Turning a broken hub to a synchronous serial controller. The hub is routing power, load, clock and data to all connected tiles via ethernet cable. The hub was gutted apart from the ports and regulator circuit. One added stamp is driving the display data to all individual tiles. This was done for Sauma exhibition demo-mode only where we have set of six tiles fastened to a tabletop and in this case wired to this hub. The playable tiles are naturally as wireless as always.
