Bluetooth Spirit Levels   (0)  [vote for, against]
For the pragmatic perfectionist.

A pair of electronic spirit levels which detect the angle at which they are being held using mercury tilt switches or some such cleverness. This information is transmitted from one spirit level to the other allowing you not only to ask the question, "Is this level?" but also get the answer to the question, "Is this level with *that*?"

Why? Because houses aren't square and a picture that is hung level doesn't always look right.

[later: When I said 'level with that' I meant 'at the same slope as the other object' rather than 'at the same height as the other object'. I apologise for any confusion caused.]

Electronic Barometer... http://www.techlib....nics/barometer.html
...with an accuracy of about 0.01" Mercury. [st3f, Oct 04 2004, last modified Oct 05 2004]

0.01" Mercury... http://www.usatoday...weather/wbarocx.htm
is equivalent to about 10ft altitude change. [st3f, Oct 04 2004, last modified Oct 05 2004]

Laser Level http://www.sears.co...te=&pid=00939922000
No idea if it's 8th's. [st3f, Oct 04 2004, last modified Oct 05 2004]

incliTronic plus (digital inclinometer) http://www.bmi.de/e...n_elektronisch.html
The second item on this page is an electronic spirit level/inclinometer with a digital read-out. Perhaps if you ask nicely they'll add bluetooth for you. [kropotkin, Oct 04 2004, last modified Oct 05 2004]

I have a laser level (which is pretty good) but this would be even better. Croissant.

The centre of mass of the Earth/Moon/Sun triplet, shirley ?
-- 8th of 7, Feb 06 2003


The centre of reference should be an international standard of level, kept as a steel bar in Paris. It should automatically communicate with all spirit levels the world over.

I have a feeling that this is not on the level.

The major advantage I can see here is the abilty to effectively have a very long spirit level. Getting posts the same height in the garden for instance, or very long shelves - basically the longer the level, the more accurate you are. However, the levels would actually have to know more about where the other one is, rather than whether they themselves are particularly level - a bit more like a bluetooth theodolite really. still - pastry.

A carpenter I knew did revel,
And drank spirit from his own level.
He became quite uncouth,
Got a black and blue tooth,
And nailed a Tasmanian devil.

Rods: Relative to 'down', as measured by apples.

FJ: It's as level as everything else. I measured it.

goff: you'd need to be able to get relative height out of the devices for that to work. You could put a barometer in each which would give you an accuracy of (googles... links...) about 10ft. I get the feeling you'd be better off investigating 8th's laser level for an application like that. (links to a laser level)

*blink* (realises that everyone thinks he's talking about height rather than slope, adds to idea.)

Ahhh I see!
Electoronic spirit level calibrated to particular wonkiness. More half-baked than I though! Still, would have been useful in my old victorian house....

Paris, Texas - as Paris, France will be levelled, hopefully soon.

We'll fill it in again after we have buried all our radioactive waste in a big pit, but we can't promise it will be completely level.....

Nice, underfloor heating.
-- oneoffdave, Feb 07 2003


Nice. I had a similar notion just there, but without any of the electronic gubbins, relying instead on a twin bubble system - one fixed parallel to the spirit level body and one rotateable-along-the-short-axis bubble, which I think would work just as well. Might have to make the adjustable bubble chunkier, so that it can be fiddled with with greater ease.

A garden hose with 2 short pieces of clear tube , mark both tubes , then fill till they equal each other , a rubber cork or 2 so you don't loose any fluid as you tromp about your house or what ever , you can set fence and deck posts the same way . one advantage this has over a lazer is you can go around corners with out fancy mirrors and prizims
