LOL - I never would have guessed dollhouses...

I did some experimenting with both diode and capacitor droppers.

The diode circuit required about 14 ohm resistor that kicked out about 1.25 W.

I used a 11 uF cap (two 22 polarized back-to-back) and a 6.8 surge resistor that kicked out about 0.6 W. It also has a softer startup than the diode circuit so this is what I'll go with.
Next time i place a parts order, I'll get a proper non-polarized cap.

I also added a 1 A fuse for safety.

Thanks for all the tips
