Electrolytic capacitors don't like to see reverse polarity (they tend to spill their guts rather dramatically). Therefore, C2 & C3 (on the input) should either be a single nonpolar unit or each capacitor should have a (fast) rectifier across it to ensure they don't see reversed polarity. Assuming your target is 50uF total, each capacitor can then be reduced to that value.

I still think this is a really cool DIY project. Has anyone else dipped a toe into this one?
