Homemade Transformer? Answered
Moved over to the UK from the US a couple of months ago and my fiancee has brought with her a 110V tea-steeper with her. Apparently it possesses magical properties that cannot be reproduced by other local appliances.
It will blow out the fuse in a 500-watt transformer, which is the largest that I have. My question is, why are these things so expensive? I have very limited knowledge about them, but from what I do know they don't seem that complex. Some of the higher wattage transformers are the same price as a netbook computer! What is in them that costs so much?
Also, can you make your own?
