A new project for 2012. Based on the TouchEmulate boxes, I have created a simpler, smaller unit to output DMX only.
This makes a handy DMX remote combined with TouchOSC (for Android & iPhone or DMX Focus from Foo Bar Interactive (for the iPhone) and a router.
The box accepts OSC commands to set channel levels over the network and has a web interface for setup. A simple, mobile phone or tablet remote for your dimmers, just add a wireless access point of your choice.
You can configure the IP address of the unit via a web interface in a similar manner to setting up a router.
