Yup - very nice!
This motivates me to try hacking a Socket Rocket, replacing the triac with a SSR for better control of transformer wall warts.
The standard SR distorts the sine wave just enough to make a small transformer run excessively hot. It's a bit disturbing to look behind the dresser and find the wall wart case melted down around the transformer after a year of what I thought was safe operation. I had two 5v wall warts powering "Flameless Candles" used for accent lighting. Both were melted but still working.
Yes I put that in my "Lessons Learned" book.
FWIW the inductive wall warts were replaced with cheap cell phone switching chargers, which do not seem to be bothered by the triac wave form (he says confidently).
Mark, thank you very much for the professional write up.
