For a long time I wanted to control my ledstrip over a network (local wireless for example), one way to do this is via OSC (Open Sound Control). When I found out the Teensy is capable of dealing with this (via slipOSC), to send OSC messages/bundles over an usb cable I was a step closer.
Then the maker of OSCulator (software to route OSC messages and more) made a small application to connect OSCulator with a Teensy board. Thus a bridge between OSC over UDP and slipOSC.
So he sent me his first tests of this bridge, and I started fiddling around to get it working with fastspi. Now I made this basic setup to control my led strip with my computer.

So much more can be done with it, it’s just a super easy way to communicate with your teensy, now to control LEDs (WS2811 by the way)
