Hello there grim,
I think it would be a good idea, and you should provide a link so people here
can take a look. I also believe that you should provide links to sources for
materials such as transformer cores, wire, winding tape, etc., so that people
will know where to get the materials if they decide to build one up. Of course
the links should include places to get single piece quantities so hobbyists can
obtain what they need without having to buy the whole store.
