Stratux Compact Single SDR

thingiverse

I designed this case to be as compact as possible and to address some issues I had with most Stratux cases. Specifically, it uses a barrel connector for power instead of plugging directly into the pi's fragile USB connector, it has a power button to shut down the pi without using the web interface, and the antenna is internal to keep things organized. It only supports one SDR because I was only interested in the 978 band. Things you'll need: - The Stratux GPYes 2.0 (Other cases that are similarly sized may fit, but there's limited extra length available) - The Stratux UATRadio low power v3 (This is a tight fit, and anything larger will not fit) - A 30x30x7 fan - A 5v buck converter (See pictures, anything similarly sized should work if you glue it in. You could also feed the connector 5v and skip this.) - A 5.5mm barrel connector. See pictures for style used. - A short 978 antenna. This is a tight fit and requires some patience and creativity to install. You could probably use one of the longer ones and just drill a hole out the end for it to stick out. I may do that if the short one doesn't perform well. - M3 and M2 heat inserts. M2 hold the pi in, and M3 hold the lid on. - A tactile momentary push button and a stripboard to make the power button. The mounting holes for the stripboard are 2mm and spaced 6x20mm. There are two locations in one corner for the power connector. The plug is there to fill whichever one you don't want to use. The fan rivets are how I attached the fan to the lid to keep things low profile. Just drill the holes in the lid to fit the rivet and insert it through the fan side. I heated up a piece of metal and softened the rivet with a heat gun very briefly then used the metal to press down on the rivet to melt it down toward the lid and expand it so it won't fit back through the hole. Like a rivet. If you're not familiar with using a button to shut down the pi, googling 'pi shutdown button' will give you plenty of good examples.
