Update on 2015/07/23: The PortaPack H1 is now available in the ShareBrained store.
I got my LCD + audio + controls "shield" for the HackRF Jawbreaker working reasonably well, and wanted to show it off, doing wideband spectrum analysis:
I'm bringing this thing to DEF CON and Black Hat, and would be happy to show it to anybody who's interested. :-) Just look for me (Jared) in the DEF CON Hardware Hacking Village or Wireless Village. I'll also be at Black Hat Arsenal with Mike Ossmann, discussing all things HackRF. See you there?
