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. (See the BlinkStick below).
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 one of the cheapest (especially if you live in the Uk where shipping is free). It’ll set you back just £4.99
The BlinkStick 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
