The "Toybox" is an audience interaction platform for internet stream performers (like those on Twitch and YouTube). It's a whole big thing so its got a whole project site at Hackaday.io - go there for complete up-to-date intel:
Ingredients
Arduino Uno or Compatible
OSEPP Shield
Java IRC / Serial / Bluetooth Bridge
Tamya low-power servos
RGB LEDs
BigBoard ("Now in Actual 3D")
Ethernet-enabled over-sized "gauge" style meter, for monitoring CPU or other loads. Approximately 5'x3'. Cheap cardboard prototype.
On boot, acquires DHCP and blinks its IP address out an LED appendage. Why I did not use the gauge itself I don't know. That was dumb.
Sending simple integers in the range 0-100 to BigBoard's TCP or UDP port 6863 updates the gauge position. Anything that can send an integer over the network is ready to go!
