I got my iGuino all installed into the car (it's been waiting for me to do the in-car connections for weeks) and took it for a short test drive. It started right up and ran like a charm until I came to a stop, the screen went black and wouldn't come back on. It shouldn't have timed out since the car was still running. The backlight came back on when I started from a stop later during the drive, but the numbers weren't changing (like it locked up). The IM reset when I touched the area where I have the large cap and the 7805, but nothing would update. Anyone else run into this problem? Could it be that my large cap being 470 is just too large, or is it more likely that I botched my soldering somewhere? Now that I know it's working, I will be posting pictures of the buildup soon. I am pretty stoked that everything worked when I started it up!

update:
I have been running it for a few trips (to work, home, to the store) and no more glitches. The only thing I changed has been display brightness (at brightest setting). I think I will switch that back to the 42 setting (lightest backlight-on setting) and see how that goes. Hopefully I don't have to have the brightness cranked, because at night, this thing is seriously bright, even at 42 (so I am adding 10 and 20 settings to the new upload and we can test those out). The speed can be a bit jumpy (perhaps v0.71 will fix that), but nothing I couldn't live with. I can't wait to have a way of reading RPM in my car! Both cars that I have owned have been 5-speed-manuals, and neither has had a tach... so even if it isn't exactly on, it will be cool.

EDIT
I think there has to be a lose wire somewhere... I was cruising along last night and came to a bump in the road and the display went off instantly. I noticed that the yellow light on the iDuino was still lit, so I didn't lose power from the car, just somewhere in my setup. Will have to poke around with a multimeter when I get the chance, maybe just re-touch all the points with a hot soldering iron.
