• Why don't they make the red LED lightbulbs using gallium arsenide phosphide (GaAsP)?

    I've opened up the package of a walmart red LED party light, and it's a ring of white (about 5000k color temperature) LEDs on a PCB underneath a red plastic dome that absorb most of the light and heats up! Why not just use a semiconductor that already emits a clean red, and that doesn't need to be filtered? Odds are, it's... show more
    I've opened up the package of a walmart red LED party light, and it's a ring of white (about 5000k color temperature) LEDs on a PCB underneath a red plastic dome that absorb most of the light and heats up! Why not just use a semiconductor that already emits a clean red, and that doesn't need to be filtered? Odds are, it's marginally cheaper to use white. I first ran into this when the LED brake lights came out, they were a rich red, now all I see are the white brake lights, and I'm kicking myself for not getting the really red ones when I had the chance. So the question remains; why can't I find a red LED light made out of real gallium arsenide phosphide (GaAsP) red LEDs? An acceptable answer would be that to get the same light output it would have to be the size of a basketball and it would cost $175.00!

  • Honestly, why did they change the Land-o-Lakes package design?

    Didn't they realize that the Droste effect was one of the product s best features? Now, by zealously cropping the image, they have lost that something-special that it had. Maybe It was so that people wouldn't make the the butter-box reveal gags anymore...or maybe it was because she was kneeling... I don t know anymore.

  • What's the second, third, or maybe fourth best way to block radioactive iodine?

    Scenario: You are in a cabin on a hunting lease, and you hear on the am radio that the nuclear power plant seventy five miles to the north was just hit by a tactical nuke on a cruise missile that somebody shot out of a back of camper-van. It's bad, but it's not quite like Fukushima and it sure isn't like Chernobyl! Yes, it was a nuclear explosion, but they said the reactor core was fairly well contained, as these things go, and they think that everybody outside of the 50 mile radius should be okay as long as they shelter in place and take iodine. The problems are that you don't have those red iodine tablets, and you don't even have Lugol's iodine. Your sister took the jeep back to the city, and she'd have to drive right past (within nine miles of) the power plant to get to you. The nearest town (in the other direction) where they might be handing out tablets is a 27 mile hike down a lot of dirt roads. There's a cold front on the way, and it would probably blow that cloud of stuff on you before you could finish hiking down the road to that town, so you only have a couple of hours to act. Here's what you do have on hand:

    Pictures and even video posts were available to pretty low level users, then *poof* it was all taken away and put completely out of reach for the casual user. When I was first level it was bumped up to third level, then maybe bumped again since. This is a test to see if it's available to me.

Almost daily I hear that so-and-so pleaded guilty to charges of perjury and obstruction of justice... etc, and I wonder if pled has dropped out of the language along with whither and whence. Pleaded sounds too much like either the sound that sheep made in the past, or a nicely made bed.

    So' I've got this 1 1/4" socket with a 3/4" drive, and it's holding up admirably, and I've got this homemade 3/4" breakerbar made out of a piece of 5" web angle iron welded onto an eight foot length of 3" web angle iron, as a cheater bar. (that assembly alone weighs about a hundred pounds.) I've gotten the tire to quit spinning by using ratchet tie-downs to hold solid rubber chocs onto the tire. The weight of the car wants to roll up and over the choc when I crank on the spindle nut. I applied 140 pounds of downward force to the end of an eight foot cheater, and all it does is bend up the 3/4" (19mm) drive because it's just mild steel. I guess I'll have to do what I did two years ago, and cut the shoulder open with a dremel then crack the nut off with a coal chisel and a baby sledge. I don't think they are reverse threaded on either side (no documentation) I'm just checking. Oh, and air hammer doesn't do anything either.

    So... a coulomb is a quantity of electrons or electron holes, that would be the number of electrons that would course through a wire in one second of one amp of that wire. It's also the number of electrons and their holes that would be on the plates of a one farad capacitor at one volt. Now let me get this straight; if one took an ideal, shorted, one farad capacitor that was truly electrically neutral, and charged it up with a one volt power source, (battery?) it would then have 6.242x10^18 electrons standing up on the surface of the negative plate, and it would ALSO have 6.242x10^18 electron holes wandering around in the matrix of the positive plate right? One coulomb of negative charge on one plate and one coulomb of positive charge on the other-- the holes that were left over when you moved the electrons from one side to the other! Let me further assume that if you charged that same capacitor to a potential of two (2) volts, that you'd have 1.2484x10^19 electrons (two coulombs) stored on the negative plate etc. Under triple the pressure, you'd hold triple the quantity right?
