Hello, I'd like to build Thomas Scarborough's "Everything-that-moves ALARM" circuit but am not sure how to configure the #30 s. w. g. enameled copper wire for the Tx & Rx. I just recently purchased all the components and the enameled copper wire to complete this project but need some clarification to proceed. In the circuit diagram it shows the Tx & Rx are formed in a circular fashion. If I was to make the Tx out of a 12 foot (144 inch) form (as suggested in the notes) in the shape of a circle then to have 5 turns in that form then I would have to wind it once for each 28.8 inches of the length of that form? What material would I use for the forms to have them inconspicuously hidden under, say a carpet? Can anyone here explain the best way of doing this? Thanks jess
