This initial goal defines the characteristics of the device: * Small (to be easily carried in my pilot bag) * Autonomy: 3 hours minimum with batteries (no power socket on the plane) * Extremely basic user interface (no LCD, just a few buttons) as it is not designed to navigation instrument) * Storage capacity… text/html 2010-04-24T18:39:28+00:00 Guillaume http://www.guiduc.org/wiki/projects:gps:v3?rev=1272134368&do=diff Features After two prototypes, the aim of this third version is to be really usable in plane or in car. This imply that it is small, well packaged and includes some missing features in earlier versions. * Storage on micro-SD card * 16×2 LCD screen that displays: * Status (GPS satellites in sight, space remaining on the SD card...) * Latitude/Longitude * Ground Speed * GPS altitude * Track * Menu (start/stop acquisition, erase previous acquisition...) text/html 2009-10-12T12:17:30+00:00 Guillaume http://www.guiduc.org/wiki/projects:alarmclock:alarmclock?rev=1255349850&do=diff The aim of this new project is to build a small alarm clock. This is a work in progress so this page is a draft not very well organized. Features * Receive DCF-77 radio timing signals to stay on time * Internal crystal to maintain time if DCF77 signal is lost * Battery backup if main power is lost * Alarm * Optional time offset (to add x minutes to the real time) * Time is displayed on 4 7-segment LED displays * Several status LED (DCF77/internal crystal, main/backup power, offse… text/html 2009-10-07T09:15:30+00:00 Guillaume http://www.guiduc.org/wiki/start?rev=1254906930&do=diff Bonjour et bienvenue sur mon petit site web.
