Almost 36 hours, and the light is still working.
And, still using the cheap carbon zinc battery.
That surprises even me. I remember the day when we got three or four hours of light on filament bulbs. Some day I need to check the current draw of this Cree emitter.
Actually I was joking ... down in Mississippi and other rural areas in The South it was planted to control erosion . Big mistake , that stuff grows so fast you can watch it grow . Overtakes and kills most anything in it's way and has actually taken down power and telephone lines from it's weight .
At about 9 AM (nearly 36 hours, but not quite) the light went out. I took out the battery to check the end voltage. Which was 0.79 volts.
I noticed a couple drops of liquid in the bottom of the flash light. The battery turns out to be leaking. Oddly, the flat negative end had a bit of liquid, and the battery was blowing bubbles. Not sure why that is. I put some paper towel under the battery in the trash can. Rinsed out the flash light with warm water, and left it open to dry.
One amazing flash light. Doesn't do every thing, but it does a good job as indoor light when you need a little light, but not much. And the battery life is exceptional.
...
Using very crude numbers, an LED is maybe 90% efficient and an incandescent is maybe 10%. Right there, I'd expect nine times the run life. You said your experience with the old flashlights was 3 or 4 hours, so, a nine fold improvement would give somewhere around 27 and
36 hours. Bingo.On one hand you only have one cell in the new instead of two in the old. On the other hand the new one can work down to .8 Volt. The incandescent would have stopped producing any visible light long before the voltage got that low; the joule thief circuit has gotten as much out of one battery as two in the old style.
Well, you have milked this for 8 posts now. Time to move on. Perhaps test it against EMP. Can you speak North Korean?
Yes, I know...It is called the plant that killed the South. Came from Japan in the 1800's. Pennsylvanian was the first import planting. I am seriously considering Boston Ivy for my use though. By the way I ate Kudzu in many Vietnamese recipes as I imagine most military folks of that Era have. Southerners should never starve to death with that stuff around. Send some to the Mormon for his 2 year supply stash. Add some seed to his BOB. ;-p Up side is that you don't have to weed it. It even chokes out trees.
Now that winter is over, I've got to take my vehicle to the car wash. Rinse off the road salt, and clean it up a bit. Hmm. Well, today is a good a day as any.
And now.... I've found a use for the flashlight! I've got these damn run down AA batteries run down to much to be useful but still enough charge to not throw away. So a single cell 18650 battery holder with a spacer ( bolt that happens to be the right size) the test meter which doubles for the jumper wires... and now the AA is running the LED, the electrons are making photons now that won't wind up the city landfill. It's kinda like not throwing out good food but feeding it to the neighbor's dog.
No, learn about leaving in context.
Again, you've deleted context, the conversation does not follow to this point.
Where shall we start. Genesis chapter 1, verse 1 work for you or should we go back to Gilgamesh? Or perhaps send pictures of cave drawings?
The world moves on. Everyone adds and changes. Much is abridged in the daily process. This is not an historians club.
No, the bible is the biggest work of fiction ever.
Context and history are not the same proportions at all. I leave in 5 levels of conversation, that's always enough to work out what people are talking about.
But not for the self-righteous who believe in a book of allegories.
You talking about Stormin' ? Or do you fancy cave people had books of allegories?
As intelligence increases with each generation, religion decreases.
Aren't 50% of yanks religious? I'm assuming a lot of you are American.
Assume your heart out. I don't know. Do you?
Yes, I'm American. Yes, the alt.survival group is heavily American with people from Australia, Canada, and a few other places.
What's your train of logic that assumes I'm in one particular half ? Of your assumed demographics ?
What's your train of logic that let's you morph flashlights into seeing the one true path to the god or goddess of your choice ? And that I've taken such a route ?
You must represent a nation of mind readers. Not very good ones, mind you, but mind readers none-the-less.
Can you prove a decrease in religion results in an increase of intelligence ? There seem to be examples to the contrary here.
I'd say the increase in intelligence causes the decrease in religion. Clever folk realise what they've been taught is a load of s**te.
Pretty sure.
I'm not talking about you. I'm talking about the group.
I'm an atheist. WTF are you on about?
When an atheist sneezes, should I say "nothing bless you"?
When you drop a rock on your foot, do you scream "Nothing damn it!"?
Some people increase intelligence as they increase religion. My church congregation has a couple doctors, and a couple attorneys. Those professions tend to continuing education.
As for me, I've taken a couple classes at a college, and do some other self improvement.
For example, I've been studying flashlights.
