I want to create a simple GPS speedometer for my classic car. The current speedometer is in KPH and it should not be changed. I want to place a GPS powered MPH speedometer where the old style analog (simple red digits) clock goes.
All this thing needs to do is get an MPH from a GPS and send out the three digit signal to one of those simple red digit readouts.
The cheaper the better. No versatility needed, since this is really going to be dedicated to doing only one thing, always.
Obviously, 12v is necessary, and an easy hookup to an equally inexpensive old style red digit readout will be wonderful.
Any help is highly appreciated.
