The $100 tablet ECS, an eBay marvel
You’ve gotta admire John Williams’ keep-the-costs-down / keep-the-battery-full / let’s-go-sailing philosophy. The pride of his nav station (bigger here) is this antique (Windows 95), 12v sipping, pen computer (eBay, $50) which has a Holux PCMCIA GPS card (eBay, $55) plugged into it at left, and is running SeaClear charting software and NOAA raster charts (both free). John’s blog pictures the setup here and details it here, (and don’t miss his experiments with LED replacement bulbs here). This guy is having a lot of fun with a 25–year-old sailboat and some cast off electronics, though he does admit to desiring one of these. Thanks, John!
