Reply to "TMCC Battery Replacment with Charger"

After assembling this one, I see where hand assembly will benefit from laying out some of the components slightly different, so I'll rework that. I figure optional caps are free if I don't install them, so no problem there. I also want to think about the maximum voltage on the SuperCAP, I'm right at the edge now. They are two 2.7V caps inside the wrap, so 5.4V is the max they should see. I'm close to that now.

If I wanted to use this to provide power all the time to some circuit, it would benefit from having additional filtering on the input regulator side to allow more current. OTOH, it does do the TMCC battery function as it stands.

I was pleased at how much capacity the 1.5F SuperCAP had, I didn't expect it to hold up the load that long.
