How can I make transformer at home?
Wrap two, equal-length bars of steel with a thin layer of electrically-insulating tape. Wrap several hundred turns of magnet wire around these two bars. You may make these windings with an equal or unequal number of turns, depending on whether or not you want the transformer to be able to “step” voltage up or down.
Where do you place a transformer?
Transformers should be located at least 12 in. to 18 in. away from walls and other obstructions that might prevent free circulation of air through and around each unit, unless the unit is designed for wall mounting and installed per the manufacturer.
