New speedo

Well today my speedo arrived.  It is an Autometer NV series 5" speedo.  Here is an idea of what it will look like once mounted

As you can see the dash isn't done.  I also have a matching tach, and will be getting a fuel gauge, and voltmeter too.

Arduino fixed

So I finally got my FTDI breakout board I ordered from Sparkfun.  So I hooked it up right away and it works again, finally.

Here is a pic of it

I hooked the Gnd, TX, RX, and DTR pins up.  I didn't hook up VCC, because I only need the FTDI board powered when I want to upload, plus then I can use the USB power to disconnect anything else that is on the same serial port automatically.

So pinout is like this:

FTDI  -  Arduino

Gnd    -  Gnd

TX      -  RX

RX      -  TX

DTR    -  DTR

I also had to remove the solder joint beside the FTDI chip to disable the 3.3 volt, and then I soldered I wire from VCCIO to VCC, which converted everything to 5 volts.

The DTR line is used for the auto reset feature, if you don't care about that, then don't hook it up.  Myself, I want everything to be as automatic as possible.  Once everything is installed into the car I won't have easy access.
