Hello, im very interested in putting this in my race car but am confused where I would get some of these parts, such as the LED display. Anyone care to chime in on this with possible links?

Thanks

Hi Mark,

Thanks for stopping by. Sorry I didn't put the hardware list on the V2 thread -- my bad. Everything is listed under the V1 thread. Here's the list. Go to adafruit.com


(1) Arduino Uno http://www.adafruit.com/products/50
(1) 7 segment w/ I2C backpack http://www.adafruit.com/products/881
(2) NeoPixel Sticks http://www.adafruit.com/products/1426
(1) 7805 TO-220 5V regulator (for neopixels) http://www.adafruit.com/products/2164
(1) HEATSINK http://www.adafruit.com/products/977
(1) Rotary Encoder http://www.adafruit.com/product/377

These are discrete components, shop jameco.com, newark.com, digikey.com (or try amazon)

(1) 47k Resistor
(1) 10k Resistor
(1) 330 ohm Resistor
(1) 1000uF Capacitor
(1) PNP Transistor, 2N3906 **
** This intercepts the cars ECU RPM square wave (can be found on OBD terminal) -- without it, the signal terminates through the arduino (caused my gauges to go to zero)


The housing for the LED bar graph was made of 1/2" I.D PVC tubing (picked up 25' for $6.00 at a hardware store). It's plastic, and it's coiled, so apply a little heat, some pressure, and patience to form it into a straight piece.

Hope this helps
- jon
