LOL! I hear ya!

The image size is about 3k and so far it looks to be about 1 second bootup time, plus the time to make the measurement. I figure I'll flash all of the LED's on the panel as soon as it starts then take the measurement then show the result.

If you are into Arduino, you are probably aware of a couple of good parts sites...

Actually this is the first time I've used an Arduino. In the past I've gone with pure assembly running on a microcontroller but I have to admit that using an Arduino is far easier than handling everything yourself. It really is a nice package to get something up and running quickly. (The boards I purchased came from sparkfun.com.)

For this project, since it really is a one-off, I'll just solder the circuit up on a perf-board (like these: http://www.amazon.com/Vktech-10pcs-C...VMV2J9HEQP7ER8 ). The Arduino board will sit on top. Then I'll seal it up in a box and mount it to the Axis in front of the black tank--fortunately there is a junction box not too far away where I can pull the house 12V from (including a block of fuses).
