I will be posting schematics as soon as I have built a prototype. There are still some questions about precise values for the parts I need. For example, "best results" will be obtained if I use two capacitors which cost $2.50 each, but the spec sheet also mentions that capacitors that cost $0.30 each could provide "acceptable" results.

What I'm hoping to do is provide both working schematics and ready-made devices for people who don't want to built the devices. The efficiency of the conversion and the quality of the power do depend on the parts you use, so it's not as easy as going to Radio Shack and getting whatever capacitors they happen to have.
