    Hi guys,
    I am new to this forum so please be understanding if I state the obvious etc.
    I did some electronics stuff many years ago, built a computer operated robot arm in 1979 also a sensor to 'do' one armed bandits, fun stuff like that.
    When the little lasers first came out I built myself one for leveling on a building site, I had planned on putting in some mercury tilt switches to make it so that it could only be on (lase) when it was level but I could never get them sufficiently accurate.
    My question (for that is what this post is) is, could a bulls eye level linked to a laser work? is there such a thing as a mercury bulls eye tilt switch on the market, if not what other system would work.
    My idea is that it could be used to transfer a level on a building site very easily as the dot would only be 'ON' when the device was level.
    Make any sense?
