I have the Sears 10" and 48" digital levels that beep constantly when level, but the volume is so low I can hardly hear it and if I am outside with a slight wind blowing, I can't hear it at all (I've written about this before). I heard Zercon has one that is louder, so I called them directly and they told me it was no longer available. So if anyone know of a digital level with a LOUD beep, I would love to hear the details. As far as modifying it to set off a buzzer, I would do that but unfortunately I am not a rocket scientist.

Thus there would probably not be enough power available to run a buzzer, which requires a pretty healthy chunk. the only buzzers I know that don't take much power are high frequency and thus hard to feel. Again, the entire unit probably draws so little current from the battery htat there wouldn't be enough current flow to run the buzzer. Depending on the battery used, something might be done with an added transistor to take the relatively low current voltage that runs the beeper and "switch" more current through to a buzzer, or maybe better to a pager vibrator motor. If Larry Martin actually has a person who needs a tactile level, have him contact me privately and we can talk about us doing a one-off unit for a particular person. We do have a pretty good deal of experience with making stuff vibrate. Tom Fowle Smith-kettlewell RERC [Non-text portions of this message have been removed]
