I've been working on getting openipc compiling libusb and rtl-sdr packages so I can flash it to the $15 chinese sbc dvr w/sata port (ICsee Xmeye XM Nvr Board 4K 10Ch Hisilicon chip Hi3536E IP Recorder Embedded Linux) that's openipc compatible and just use those boards for running my rtl-sdr software defined radio dongles instead of $50-100 rpis or odroids. Their build system is a bit weird but it's not bad. Having to flash over serial to install is tedious but well worth it for the price and functionality.

That said, the actual FPV/camera stuff with openipc is cool too. I definitely would rather pay $50-80 for a 2k 90fps camera/transceiver/receiver system I can hack on in linux than than $300 for a (much better) dji o3 pro. I'm hoping I can get the HDMI out formatted properly to use with my HTC Vive head mounted display instead of having to fork out for something new I can't buy (-11 diopter) prescription lenses for. There's basically no support for glasses wearers in any FPV goggles except the dji ($$$$) stuff.
