This month’s highlights

Touch-screen Boat Computer with GPS

Based on the Micromite LCD BackPack, this BASIC-programmed design offers a fantastic low-cost computerised navigation aid complete with GPS, ideal for owners of small boats. The touch-control colour LCD shows a combination of speed and heading, latitude/ longitude, time and basic distance and bearing for up to four points of interest (eg a harbour entrance or a favourite fishing spot).

   

Some examples of the LCD displays are shown above. GPS compatible. Programmable via USB-to-serial converter (details included). Demo mode. Full constructional, programming and usage instructions are included. A great project for boat and yachting enthusiasts!
