formula student, not formula 1

Megasquirt doesn’t have this built in, you need a laptop or some other means to graphically display the data.

You got an lcd screen with yours? That wasn’t an option with mine.

I did one for my motorcycle:

I’d like to see ECM and BCM firmware hacks public.

Problem with most of these is the LCD used is low grade consumer. a car LCD needs to be a wide temperature rance LCD to stay alive and be useable in the -2degF to 110degF world that is in the dashboard of the car.

Also direct sunlight destroys visibility of these if the display is not a transreflective.

thumbs up for 1p heat sink! well done, even if still in beta, hoping to see a website about it!

as far as mounting goes, i’d like to see a display (one of these projects, entire instrument panel, or even just a gps) embedded in the top of the dash at the front, so that it shines/reflects off of the bottom of the windshield glass like some old arcade cabinets. it would be like a HUD for driving.

A car that can play Solitaire finally :)

The biggest problem with a HUD using normal auto glass isn’t really ghosting, it’s that it wouldn’t be visible in bright light. Around ’98 Pontiac made some Bonnevilles with a HUD. My mom had one, and I’d driven it heavily both before and after the windshield got broken and was replaced with standard auto glass. There wasn’t really a ghosting problem, though it was only displaying the speed in large digits – perhaps finer details would cause problems. But the biggest problem with the regular glass was that, in summer in bright sunlight, you wouldn’t be able to read the display.

On the bright side, it should be possible to get more HUD-friendly glass installed in your car if you’re planning to experiment with such a system. IIRC, it’s not _too_ much more expensive than a standard windshield replacement.
