This is the heart of the system.  A full on Linux computer on a single board.

ISS-Above is built from a base of the $35 Raspberry Pi Model 2.   The software is written to support various display output options using add-on modules available to plug in to the Pi’s GPIO or USB ports.   More will be added as development proceeds.

The display may be small - but it allows a lot of useful data about the ISS to be displayed.   I'll also work on adding support for a USB attached RGB LED for a nice colorful display when the ISS passes nearby,

A favorite version of mine.  It's also the cheapest to build.  This uses the PiGlow add-on to create a really fancy swirling color display when the ISS passes nearby

This version uses the PiLite - a matrix of red (or white) LED's.

This is definitely the most simple of the display solutions I have worked with.  The LedBorg is also the cheapest (especially if you live in the Uk where shipping is free). It'll set you back just £4.99

The blnkstick is the first display solution I have supported which works via USB rather than the Pi's GPIO port.   A VERY bright RGB LED makes for some nice display options

We also support the PiFace Control & Display LCD – and the Blink(1) from ThingM as optional display devices
