Simple design project

Do you mean you need to make an LED come on based on some level out of the strain gauge?

As to a mercury switch, whether you need an IC depends on what you want it to do.

I am sure we could help, if you specify exactly what it is you need to do - in detail.

If you do that, we might actually tell you how to do it yourself :)

If you would still prefer a professional to do it (a *really* good idea if it's a commercial project), then I am sure there is someone here who would be willing provided you are willing to pay for that service :)

PeteS. Thanks for your reply. As far as an IC is concerned, I need to be able to store data and retreive it either by telemetry or by plugging in a handheld device. I need the strain gauges to post data to a storage chip that is downloadable and reset every time the tilt switch goes on and off. I can't use mercury because it is an environmental application.

Thanks, Luigi

As you have a requirements specification (at least in brief) perhaps you could share. There are many here (myself included, of course [at least, imo] :) who could design such a system. Then you can choose.

Expect any of us to charge around =A380/$150 / hour for such a project though. (although Genome seems to be cheap lately ;)

Hey, quality time down Kings Cross toilets should not last an hour, and neither would the business man . We are dealing with busy people here and they need a fixed rate with no hassle. They also need to catch their train and I need to move on to the next customer.

You're right about that. What do you think of the project? How many estimated hours would something like this take? I mean a real ballpark, that's all.

To expla>

Analog Devices do nice 2-axis accelerometers that might serve as tilt gauges

Strain gauges are usually discussed in terms of (slightly) load-dependent resistance.

Resistance is just the inverse of conductance, so you can - in principle - use either term, but in practice strain gauges have resistance, not conductance.

E-mail me a copy of you specification (to bill dot sloman at ieee dot org). I ight be able to contribute.
