BIK sensor - WAS moving away from the remote-control paradigm

They are closer than you think. I have three of the originals and made
Stuart the PCB for his soldering practice. As Stuart said he is 95% there.

of aerials

There are two aerials that are best sited at about three feet high. These
can even be the tin foil burglar strip you see stuck to windows in shops
etc. - great behind wall paper or even thick paint. Furniture moving like
chairs, tables etc. doesn't necessitate a recalibration but large metal
objects can e.g. fridge freezers might. More than one unit can be used in a
room without problems which is good as they are more accurate with less
area
covered. A good house earth is the only thing that is not really obvious
but
essential.

I have had one working at home in a test environment and it was brill. I
ran
into sensitivity problems when I went for a large room 14' X 18' and L
shaped. The answer is two sensors and sort out my house earth which is
awful!!
