Please excuse horrible blurry photo, but I think all the soldering is done \u00e2\u20ac\u201d<\/p>\n

A whole new board I soldered up is the Mini-PPISD. It adds (slow) SD card storage to an SBC board:<\/p>\n

\"ppisd-20150724\"<\/a>Man, but those surface mount SD card pads are a pain. I had to get flux on the PCB pad and the bottom of the SD connector, load a little blob of solder on the iron, then warm up the pad and roll the solder into place. It made a satisfying little Zsht!<\/em> noise as the flux burnt off, and the molten solder got drawn under the pad by capillary action.<\/p>\n

Next up is checking the power and ground continuity, adding the chips, building a null modem (grr; I hate RS232, really) and finding a case. I may already have one, but I may forage at Above All to get a 3\u00c2\u00bd” floppy drive and enclosure. I definitely have an old Turbo\/reset button from an XT that would make a great reset breakout.<\/p>\n","protected":false},"excerpt":{"rendered":"
