lolz in an "emergency" I could charge my ipod via oranges, am I rite?

i guess it could if you have a box of oranges (lol?) and all of them are wired up corrrecty...... its interesting :-]

I Like This But How Long It will Be running ?

Looks cool! I figure that the chemical reactions make the fruit go bad or make it last only a week... but wouldn't it work quite well to hook it up to citrus fruit still growing on a tree?

i am not shure, but doing this on a growing fruit i think there a 2 possible things that might happen: 1. the fruit will die 2. the tree might die... both because of the copper is very bad for plants... (if you want to kill a tree: hammer a copper nail in)

yes U R Right.thanks For Information.

lol i had the exact same kit shown in the pic.

I once had a potato clock. Until it rotted.

cool.that loooks amazing!!!good job!!:)

What is the one on the first page, Where can you buy that clock?
Nov 3, 2010. 4:57 PMynze says:
Do a google-search on "fruit-clock.jpg". You'll find a dozen websites that sell it.

Wow! I guess that they have a capacitor and run on really low energy, i had a clock that would run off the sun that i made, i am trying now to make it run off plain water

if you where to connect the wires to citrus juice would that do the same thing?
e.i. store bought orange juice?
Nov 2, 2010. 6:03 PMArano says:
it would work with vinegar ;) anything acidic should work

The 9 VOLT battery clip on the mains powered clock is for backup in the event of a power failure and will not display the time in that state, it will only keep the time for when the mains power returns. Show me a picture of the project working where your hand isn't covering the mains power cable supplying power to the clock! (step/pic 3) Make it, don't fake it! (whats the point in that?) your two cell orange battery would not have the required voltage or current to run the led clock even if it did display the time without mains connected. You would have to take out the transformer inside and bypass the rectification circuit You would still require more than the 2 volts at microamps you would get using your orange battery!? Now on a more positive note, I suggest you try an L.C.D. clock or old wristwatch. It would work at the above stated voltage/current. you can also use just one lemon/orange with a few copper/zinc probes in series for the required voltage and more surface area for more current to make it work & last. Zinc coated nails/copper pipe work better than a paperclip/copper penny. See also "supercharged lemon" instructable it clearly works well (tried) and would actually run an L.C.D. clock/ watch (as pictured in intro) for well over a week. I estimate a month or more. thumbs up for author "s8" Good try, shiboohi

Most people have a few nails and access to a bit of copper (scrap metal merchant?) I got a piece for free. How much is a box of paper clips and two pennies? more than 3 cents i suspect. I give credit where its due (s8 supercharged lemon) and i agree that the project would work with an L.C.D. clock as pictured in your intro but NOT the way you have shown and i described why. I have 22 years exp in the electronics / alternative energy industry and i put in some constructive feedback I find it funny that you take offence to that. You too have a good day ........solarMatrix.

I was looking at the other more advanced alternative energy ideas that are posted on this site (some are actually unique!) when i spotted your intro picture which i still think is a good concept which is why i took the time to put in some constructive input as well.

I might even make a solar powered led clock adaped from your post. cheers!
