We drafted up a list of which gauges should be on the dash and the list was long. A dash display would be a welcome addition that would save weight, dash clutter, and wiring. Both my brother and I have always liked Stack products except for the price; $1500 for a base model and several hundred dollars for options makes it a hard sell for a couple of broke college students. Luckily we both value our time at zero so we decided to roll our own.
I'm doing all the electronics and Alex is taking care of the mechanicals. The entire assembly is now finished in Solidworks so he started by machining a couple of molds for the housing:

This is the mold for the rear part of the housing after way too many hours of wet sanding, with many hours of sanding and polishing remaining. A sympathetic friend who also happens to be a magician with carbon is going to lay up the housing in pre-preg carbon fiber for maximum fake race car status.
The PCB is taking shape and I'm burning the midnight oil to finish up the layout. The white blob on top is the stepper motor to drive the tachometer needle and the big white box is the LCD.

It will be connected to the Megasquirt via CAN bus and will also support an AIM compatible serial data stream. It also has support for additional analog inputs.
