    Thanks! It is funny all the design decisions a person makes. The silicone wire sounds nice. I think the LiPo vendor's wire would be fine if I did not mess with it so much. I will look around for that wire.I was tempted by the EEPROM, but as you pointed out, the write count management was more than I wanted to mess with. Then the issue of menus to access the data and no reliable time stamp. The "end user" (the human - not Nugget) preferred that the child would have to write down data. You are right - overkill, but there is always the next revision! I did use the EEPROM to save the range setting as the calibration is a very low repetition event.I spent waaay too much time on this project, but it was fun. I looked a lot at displays.

LCD are the way to go except for the back light as you said. I looked at reflective LCD, but didn't see anything to appealing from vendors on this continent. Now ePaper that would be fun, luckily for my wallet, Nugget passed on before I got that ridiculous. Cheers, Bill

    Well, that was the problem. Nugget was shy. He'd only run in the middle of the night - hence the monitor. I'll ask the hamster 'mom' if shy was any wheel vids. There are tons of Nugget running around.

    I was rather surprised at his speed and endurance. Nugget was a beast!

    My pleasure!I made lots of jokes about this is how I make my first million dollars. (:- )
