The members of Shackspace continue to put up impressive hacks based around the tiny TP-Link routers. This time around [Timm] has shoehorned a DALI controller inside the router case. This is a protocol we don’t remember hearing about before. The Digital Addressable Lighting Interface is a control network for commercial lighting. That way people responsible for taking care of large buildings can shut off all the lights at night (to name just one use). The new room at Shackspace has this style of controllers in its lights.
The two brown wires coming into the router make up the data bus for the DALI system. It connects to the add-on PCB which uses an Atmel AT90PWM316 microcontroller. The chip is specifically designed for DALI networks which made the rest of the project quite easy. It talks to the lights, the router talks to it, bob’s your uncle, and you’ve got network controlled lighting. Get this in a big enough building and you can play some Tetris.
In case you were wondering. Yes, this project has already been added to their TP-Link firmware generator.
