[ame=http://www.youtube.com/watch?v=01FiDD_zG-c]Prototype of dash display - YouTube[/ame]
Not much to see - I'm now using the real compass and temperature sensor chip.
The -- on the display is set to show up when the compass is tilted too far (it's not accurate unless it's flat). When it's flat it shows N E S W NE SE NW SW. It's possible to add an accelerometer to compensate for the tilt, but I don't think it will improve enough to be worth it.
The temperature display is climbing because I put my finger on the IC. In the finished product, the chip will be on the end of a wire so you can keep it away from things that generate heat so it will be more accurate.
Voltmeter is just using a ~12V adjustable supply that I'm turning the potentiometer on.
Just need to get the speed sensor and crankcase sensor and button it up. It looks like a huge project on the board, but the actual components are quite small. The Arduino nano is only 0.73" x 1.7", and the rest is mostly just wiring. It should easily fit in the size of an Altoids tin or similar case.
Note: Ignore the "vv" on voltages < 10v, I already fixed that bug. Not that you should see voltages < 10V anyway...
