Have any of you guys built this $24 dash indicator?
Think I'll give it a shot...parts ordered.

Hi Daryl,I'm quite curious how you did those buttons. I'm planning to try one myself so was wondering if you could help me.
I can think of two ways to work the button. One would be to use the button to trigger a message to the computer via the serial port of the arduino.
The other way would be to use a teensy as a joystick, and emulate the buttons of a joystick.
Did you happen to do it via one of these two ways? Or is there another method that I'm not seeing?
Do you think it would be possible to use a little TFT monitor with arduino to make a dash?
I just soldered new wires on the backside of the print, on top of the existing button connections..
o the old mini buttons are still there under the plate. I like simplicity...
The buttons come from DX.com.

mostly the buttons with 3 pins have 2 groundpins and 1 contact.
You have a mulit meter to see the function, or can you post a photo.
My buttons had just 2 pins.
Usually 3 pins means 1 C (Common), 1 NO (Normally Open) and 1 NC (Normally Close)
If your buttons are exactly as the ones in the link you provide you have to solder to pin C and to pin NO, but if nothing is written on your buttons, you'll need a multimeter as Richard said.
