MSP430 Low Power Demo using Grapes as a Power Source

[JonathanLeeMiller]

Phew... - The computers won't have to use humans in the future.....

[gravisan]

wine is seriously cheap in france.

[zero3609]

i would be impressed if it could be powered by one of my turds

[papalevies]

Big deal, GLaDOS could be powered from a potato

[sharperguy]

Doesn't the fruit just act as a salt bridge, to cause the reaction between the two different metals which actually form the cell?

[dagda786]

those French fags would get the grapes

[adrianTNT]

I thought it is some kind of joke when I saw the fruits there :)

Now seriously, when we will buy laptops battery lifetime will be written like this:

"4 hours with 200g lemon"

"6 hours with 300g lemon"

[avnsun]

I wud eat a fruit salad instead lol

[tj48014]

very funny! thx TI! after hours of debugging code, this made me laugh... I might be losing my mind?

[muhyin]

anybody knows how much its current consumption ?

Gah. Stop cutting to one clip of b-roll and back.

[MrTTUStudent]

"That would violate TI's policy" Wow what a wonderful company to work for, where that goes in the promotional video. "You didn't actually smile did you?.. Noooo that would violate TI's policy."

[rfengr]

those are really impressive grapes !

[rfengr]

sweet, now all I need is a fruit garden and I'm ready to go ..

[smrtt92]

But then... What will we eat?

[xZeeMx]

batteries?

[Kyocus]

I chuckled

[adrianTNT]

@smrtt92 there will be another 20-30 years and they will make batteries that we can eat :)

[Meteotrance]

lol only with sugar from the fruit awesome i think sony as made an mp3 player working with sugar energy ^^ it's awesome !!!

[cyborgtroy]

Actually it's the voltage difference in the metal electrodes.

[joeythegeek1942]

i knew about lighting a LED with a potato, but a microcontroller with all kinds of other fruits, cool. a new power source for my projects. now i just need to start a garden, funny.

[timlover36]

I LOVE GRAPES!! If i could i WOULD totally buy that!!

[lambedan]

They have a development kit for $20 if you are interested. Plus you can get free samples in DIP package.

[UpiFromPoland]

In past I maked this experiment with three apples. Thats work ;)

[Cafeteria]

reference design or schematic? (or as the internet meme goes, "or it didn't happen")

Seriously, do you run that into an SMPS, or what? Or do you actually get >= 1.8V and a couple of milliwatts out of the grape?

Just curious.

[jcup2306]

There is no schematic. Simply string 3 pairs of zinc and copper leads (or heavy gauge wire) in series and hook into power pins on any MSP430 eval board running the Real Time Clock code you can download from the TI website. Thats it.

[gdavis9999]

Great video! I saw this demo at a TI show and it's impressive. Thanks for a job well done!

There is free power in fruit?

[kdorff]

Does drinking alcohol really violate the TI policy? Or just drinking at work? :)

[Mutal1ty]

He meant at work, where he is shooting that vid.

[kdorff]

Surprisingly, I knew what he MEANT, I just thought it was funny.

[funpeople49]

wow talk about stretching an idea way beyond its means we get it the product uses a low amount of energy now please stop with the fruit references please consult me before trying any further hip youtube promotions like this thanks
