Heh.  Neat.  Now try it with an iPhone.

This seems like one of those elaborate hoaxes that people do just so they can get somebody to plug their I-Pad into a lemon or onion or whatnot.
 
2013-03-06 11:32:12 AM  
That seems like a pretty stupid way to go about it. Especially when it's easier to just repurpose the peltier device in a coffee warmer to charge your phone:

This is the same guy that was linked to last week with a video on how to use a stick of butter as a candle.

You need fresh fruit for that.

Doesn't seem like it would put out enough amps to charge... Thinkgeek has a similar "hand-charge" product, and that is one of the questions about it if you read the Facebook comments.

Now I just need to hire an illegal to spin it for a few hours..

Seems like a lot of work. If I was in a blackout and needed to charge my phone, I'd use the charger in my car

Implying that everyone owns a thermoelectric coffee warmer? I don't, but I do have an electric drill.

(Of course I also have adapters to charge a phone from my car's 12V socket, but where's the fun in that?)

I don't have either of those, but I do have an electrothermal drill warmer.

How long would you have to crank that thing to power a stargate though?

FTFA: "Basically, with his set up, King of Random was able to generate the 5 volts needed to start charging a cellphone. He had to test the voltage several times, and he also had to regulate the speed by which he rotated the wooden spoon. Crank up too slowly, then the battery won't charge. Crank up too fast, then you might overheat the system. "

Wait, you mean to say that there's people out there without 7805 linear regulator ICs that can produce a stable 5V output if you supply it with ~7-35V input? I've got a bag of about a dozen here on the shelf.

/also has some LM2575 switching regulators for more efficient regulation

Who are you and when did you move into my house?

You only need enough to charge a couple of 12-volt car batters, as long as you're willing to move the chevrons into place by hand.

it's not a MG fix if it doesn't involve killing someone  with an explosion when it would have been much easier to shoot said person if MG didn't have a hang up about killing with guns.

Bah, MacGyver would recharge his phone with nothing but a can of chick peas and a bandana.

He started with some basic household items like a piece of wood, an electric drill, some wire, yarn, and egg beater, and a wooden spoon

I don't have any of those items in my household.

As long as it put out 500-700 mA, it'll work as a trickle charge on most phones, and if it put out 1A it'd actually work as a fast charger for most phones out there (yes, even iPhones).

Me, though, I'd just go with a MintyBoost, but that's me :D

And mine, for when generators et al aren't available:

Though homebrewing your own with a 7805 also works if you want to use a higher-voltage power source for more longterm power and charging.

/yes, count me in with the "doesn't EVERYONE have hot and cold running 78xx series voltage regulators?" brigade :D

Hell, i got all that and a couple of Peltier junctions lying around as well.

And of course, enough old DC motors from dicking around with RC and robotic stuff, i wouldn't even need to dissect a drill.

Cool site. I already saw 12 things I don't need, but I'm going to buy anyway.
 
2013-03-06 03:49:58 PM  
I'm sure that's against your ToS.  The electrons that are generated by the drill are still under copyright.  Downloading them to your phone is illegal and the whole rig comes under the heading of a device designed to circumvent or disable digital rights management.

/yes, count me in with the "doesn't EVERYONE have hot and cold running 78xx series voltage regulators?" brigade :D


For this very reason, I have a 7805 soldered to a 9V plug on one side and a female USB port on the other. Whole thing is about the size of a quarter. Of course, you'll blow through 9V batteries like crazy if you're actually trying to charge up anything.

And it'll burn your fingerprints off without a proper heat sink...

Wow. I guess it's obvious that something like that exists in the world, as it's a very useful thing, but I never knew what it was called or that I could own one.

You can buy one for $2 at Radio Shack.

We don't own such a device.  However, we do have an espresso machine; perhaps I can harness the power of steam to charge my iPhone?

No, its powered by Intel.
