Update on 2015/07/23: The PortaPack H1 is now available in the ShareBrained store.
I have all the parts and PCBs for 500 units. I am now waiting on the assembler to start cranking them out. I wish I could give a firmer update at this point, but the assembler has not yet scheduled assembly. Once assembly starts, I'll post another update and let you know how it's going. Maybe with pictures, even!
