Step 7: Fold Twice

fold the paper twice into this size
<p>I love it both as an exercise ... esp. to show kids how things work ... &amp; it would be terrific in a power cut. I have a few spare globes like this one, and always have aluminum foil in the kitchen &amp; tape in the desk ... Clever idea. :) I don't have all those other parts that someone else mentioned they would have on hand. </p>
In the event I planned to have this many batteries on hand I also plan to have several battery holders and jumper wires on hand to be able to many voltages available easily,and quickly. A good exercise in improvisation though.
us an led lamp. cost is $3 on ebay
An LED lamp is great idea. But if I am going to buy something to have in an emergency, I doubt it would be a $3 LED. The point of this seems to be &quot;use what you have&quot;.
But what you will have in an emergency, is what you have planned to have on hand in an emergency. Have lamps, and spare batteries on hand, isn't really different than planning to have this many AA batteries on hand.&nbsp; Planning on having to improvise is part of the plan as well
it looked like some bullets when i first saw the first image lol
This might be valid, but jump starting a car is absolute BS
I did use it on car's battery once. Next when your battery is not fully dead and the startor can slowly run, only left the staror to car battey and other cable connect to your package battery...
i think that may of just been luck. the pack kept my laptop going for about 12 minutes. i powered it through the dc charger port tho not direct to the battery terminals as the regulator circuit is inside my laptop battery and the charger regulator is inside the laptop.
it would work for a laptop...for only about 5 to ten minutes laptop batteries are about 5 amps the cells are about double the size of AA My AA battery pack compared to my Laptops battery pack makes it look like the AA is a mini version of the large one
It's meant to be a last straw. (duh!)
The...last straw?
This is great.
9v batteries stack easily w/o tape
I gave mine a try and it worked but the aluminium foil was really really hot after.
the key point is to use thim in layers and press them firmly to make them into ONE wire. try to ford them more layers please
Wouldn't this quickly drain your battery? I know my 12v desk lamps are all 50w, they don't sell others.
my bulb coming from IKEA, it is a 12V / 10W only
thats pretty cool !!
