    The title says it all. I am a newbee in the field but have found a product I need and is not sold on the market so i guess i have to make one. I race motorcycles in the desert (Paris-Dakar style races) and for navigation you get directions like travel 3,48km in 187 degrees.

    GPS modules output a NMEA datastream were i want the "Course over ground". It is expressed in degrees 1-359. I want that info on a display with good readability and large digits for example a 7block LCD. Nothing more nothing less.

    I do CNC casings for a living but electronics is not my thing so i would need help to prototype the electronics....

    Most GPS's desgined for walking/sailing that I have seen do exactly what you want, e.g. the Garmin ETrex series.

    I know, today i use a Garmin 60 series coupled to a external display so that i can read it going 60mph offroad. Crashed a month ago and destroyed both GPS and the external display which is 600€ on its own.

    So i figured a 40$ GPS module some electronics and a 3 digit display enclosed in a aluminium case would both make a smaller package and be less prone to cracking when crashing.

    Sorry, I obviously misunderstood the term "and is not sold on the market".

    A Garmin Etrex can be had for £60, here's the display

    Good thought but the garmin display is insufficient.

    That is why today most people use a Garmin GPS which has a cable output. The cable output is connected to an external CAP display showing the heading. Expensive and you have 2 devices that can malfunction.

    You would need a GPS module + a microcontroller programmed to turn a series of readings into a compass directions + the display. Not a trivial project.
