Case for Stratux ADS-B Receiver

This is a case design for a Stratux ADS-B receiver (www.reddit.com/r/stratux). The Stratux project was launched by a pilot/programmer guy and utilizes a Raspberry Pi computer with SDR (Software Defined Radio) dongles to receive, decode and transmit aviation weather and traffic information to tablet-based aviation apps such as Foreflight.

This case is a very compact design, and will accommodate two NooElec Nano 2 SDR dongles. It has access holes for the microSD card, power connector, and a single SMA bulkhead connector for an external antenna. (There are also access holes for the HDMI and audio/video connector.)

There are no provisions for a GPS or AHRS module. I use an iPad with a built-in GPS, and I don't see the real value of the AHRS, so I went for a compact design. Heat buildup may be an issue, but so far, so good.

I use six #2 screws, 3/16" long. Four screws secure the Raspberry Pi board, and two screws hold the top of the case onto the bottom. I purchased the screws from http://www.microfasteners.com.

I use a Y-cable to split the single antenna feed to each SDR. I purchased this Y-cable through amazon:

I used i-SOLIDS's Hub at http://www.3dhubs.com to print this case in white ABS, and I'm very pleased with the results.
