Powering the Arduino

Other Hardware General Electronics

Hi,

Would anyone know of any other methods to power the Arduino without using a power outlet, battery or USB?
Was thinking of maybe a vibration generator.. if possible...

Thanks
Tony

If you can get 30mA or so out of a vibration sensor then yes, but I doubt it.
There is solar cells as well.

Thanks for the reply Grumpy Mike!

Just calculating the the amps i'll need.. i think i'll have no choice but to use an electrical power source.

Maybe an earth battery (two different metal electrodes buried in the ground a distance apart)? I have no experience with these and have no idea what the caveats are, but there are some videos on youtube of them being used to power motors, fluorescent lights, etc.

I played with these in the 60s for sending audio data through the ground. I could get a range of about 25 yards with a 10W amplifier and just a pair of head phones and kitchen forks for the receiver. I didn't notice any great voltages, maybe they only work in the vicinity of badly installed electricity pylons.
