I want to build a custom LED temp gauge, how?

[arco777]

On the center top vents in my first gen, to the left of the vent where the E-transfer case buttons would be, there is an unused slatted panel. Behind it is a wiring connector with (presumably) 12 volts and wires that may run to the general area of the transfer case. I'd like to use this power and these wires to install a transmission pan-mounted temperature sender and have the display in the panel. Has this been done? Attached is a quick sketch of what I was thinking of, with 6 LEDs for a quick glance and an LED number display. I don't mind buying something to tear it apart and reshape it.

I can build basic circuits but lack experience with ICs or microcontrollers. Any advice is appreciated.

Google "lm3914"

Thanks for the link, I got a Cyberdyne digital gauge installed in November.

3 pics on that page. Ditched the individual LED idea because I needed the space and it was redundant. However that LM3914 is neat, maybe I can use it for something else.
