Cool i'll try that!

Im not sure if this will be a good solution after all. I will be changing the variables very often, and as i can understand it will require direct editing of the file. The modification of variables could e.g. be done within a nodejs application interacting via a web-interface. Perhaps the database solution would be better after all compared to file manipulation?

But can i change the variables from any user or are they static in the variables file?

When i get back to the lab i will take a look at those two and get back to you with an answer.

One last thing. When i use export var1='test' in a arbitrary user, the value is not set. Whys that? But i can read foo and bar

comment Electronic compass, RF and batteries
Very interesting input on this problem. I am glad to hear that RF won't have any impact on the signal. Currently i am aiming to use Lithium battery, but not 100% sure if it will be a simple coin-cell or a LiPo/LiFe. As far as i can understand, it should be enough to calibrate the compass with the battery attached and of course necessary to do so for every IMU (as you would normally do anyway). In other words i should be able to put it all together and calibrate it once, although i will have to re-calibrate in case the battery or any other part is replaced/changed.

@terdon, if they are modified it has to be done globally, which introduces some problems. And the new value has to be maintained and not reset when the system is rebooted.
