I came across this and think it is amazing. Recently I decided to ditch GRT for WingX in the cockpit via iPad mini. Now when I saw this project it compliments the Stratux because it use the wifi network to send the data to the ipad. Ditching the GRT, I would still need to figure a solution for engine monitoring, this project solves the problem.

Engine Page Display
Summary: Enguino (a portmanteau of engine and Arduino) is an inexpensive (as cheap as $100), lightweight (2 ounces w/o case or cables), small (about the size of a bar of bath soap), open source engine monitor for experimental aircraft. The engine monitor is displayed on a tablet as a web page. Here is an example of a typical Enguino display. The tablet can be an iPad, an Android or any other tablet that includes a modern web browser and has wifi.
Enguino is intended to work with the Stratux ADS-B receiver which is also open source. The Stratux acts as a Wifi router for Enguino. For airplanes not equipped with a Stratux it is still possible to create an Enguino system with slightly different hardware and a small change to the configuration.
