InfoNinja is an Open Source Ethernet-connected desktop heads-up display. It works in tandem with a desktop computer to give you an at-a-glance secondary display of both text and ambient (color/blink/fade) information.

It is also a tea timer.

More detailed information and instructions about InfoNinja can be found at


There are two pieces to InfoNinja, each split into its own section:

The hardware is the InfoNinja box itself. The firmware runs within InfoNinja and provides a lightweight REST-enabled web server. It receives commands over the network and updates the text and lights.

The software runs on a desktop computer. It can query various environmental conditions — things like weather, bus times, the stock market, recent Tweets, email counts, automated software builds — and then tell InfoNinja to do things like flash red or print status.

The two work in unison to give you any information you need.

Something went wrong with that request. Please try again.
