Update on the 2″ gauge.

I finally had the time to come back to the gauge and get the firmware finished!

I had somehow managed to do damage to the Arduino Nano such that you couldn’t upload firmware to it using the “normal” method in the Arduino IDE.  Turns out I’d blow the rxdata line going into the ATMega 328 MCU on the board. 🙁  The good news is that I’ve got it replaced and the firmware is done.  Next step is to make some high quality faces, new needles and new instrument shells.

Here’s an interesting bit of trivia for you – the F-15C can consume up to 150,000lbs of fuel per hour at low altitude and in full afterburner.  That’s right around 22,000 gallons of fuel per hour!  Those F100-PW-220 engines are hungry! 🙂
