Make a super simple barometer form a beer can and beans tin.
I am a 1st year student at Huddersfield University (studying software development) and being a student I am both skint and up to my elbows in trash (lazy flatmates never clear up after themselves!). So I though I`d combine weather and trash utilisation in one simple project.
There are simpler designs for barometers (though not much simpler it must be said). But this I think is effective, although quite vulnerable to temperature fluctuations, but if you keep it indoors it should be okay.
Here is the result (see image), apologies for the poor quality photo`s, rubbish camera and poor lighting I`m afraid. I will do my best to supplement poor pictures with hand drawn graphics where required.
Although everything featured in this instructable is found around the common household it doesn`t make it safe. Beware of sharp edges from opened tins, never allow minors to work with sharp objects. Keep Away from electrical items! It may spill, water is used in this project after all, and yes, keyboards are electrical items. I accept no responsibility for injuries or damage caused by this instructable, although the probability of any injury/damage is slight, to say the least.
This is my first instructable so please, lots of feed back (if you have any, that it) and don`t hold back on the comments, whatever you do, don`t `go easy` on me, nobody ever learns anything from that, thanks.
