As I speculated in the last post, my Mouser order finally showed up in the USPS tracking, and it showed up in my home town sorting facility. My Digi-Key order left Philly early this morning. With any luck, both will show up today. The weather forecast calls for rain for Sunday and Monday, so I might get a chance to start constructing a test jig for the IP board.
Update: The Mouser order arrived Saturday. The Digi-Key order, containing the temperature-sensitive solder paste, is stuck in a sorting facility until Tuesday. This despite it having been shipped a day earlier than the Mouser order.
