A 7805 is a bit inefficient, and produces a good bit of heat.
I built one and encountered this when I nearly burnt myself....

More likely it's a switching regulator chip, which requires an extra inductor and capacitor on the output, but is much more efficient and runs far cooler. Still cheap and easy.

They sell outlets with usb's built in. The are like 20 bucks each.

And a couple of electrolytic capacitors to smooth out the dc ripples. And here I thought I was the only person on this site that studys electronics.
User avatar #23 - Lambda (06/25/2013) [-]
Oh yeah, forgot the caps. Probably best to put a large one after the rectifier and another on the output of each regulator.
User avatar #24 - mookiez (06/25/2013) [-]
Indeed. But you should only need one 7805 provided it outputs one amp. And then throw a led in there. Bitched love leds.
User avatar #26 - Lambda (06/25/2013) [-]
Well, an iphone draws one amp of charge current. I figure that if there's two USB ports, you'd want to be able to fast-charge two iphones at once.
User avatar #29 - mookiez (06/25/2013) [-]
That is true. I keep forgetting that they draw more power and not the traditional 500 mah. But I'm sure there is some kind of duel 7805 in some kind of package. Maybe not. Might be difficult to dissipate the heat of of that.
User avatar #30 - Lambda (06/25/2013) [-]
I think there is a different package of the 7805 that can handle more current. But you're right about the heat. It might be better just to use a compact switching power supply.
User avatar #34 - mookiez (06/25/2013) [-]
There is a lt123A voltage regulator that outputs 3 amps. Then you could have 3 outputs. But when ever I take apart charger I notice they always have some kind of 8 pic ic in it. I never really got around to see what that ic is.
User avatar #35 - Lambda (06/26/2013) [-]
Oh, yes, I remember now. It's hard to charge apple devices, they're designed to only charge on certain chargers (whose manufacturers presumably paid a sizable sum to apple).
The IC talks to the device and is loaded with some proprietary program, but there's another way to do it. The data pins of the usb port need to be held at specific voltages with voltage dividers. I don't remember the specifics but I read it somewhere a time ago.
User avatar #36 - mookiez (06/26/2013) [-]
That makes since, I always thought the ic was some kind of op amp and they were going a different route then a voltage regulator. So then you would need a couple resistors. But that would still cost under 10 bucks.
Haha, these sheeple pay 30 to 50 bucks for overpriced chargers.

Actually something similar was discussed in another comment thread. According to OP, Shell is working on ways to keep the fuel (I'll assume something like methane) at a liquid state when not under pressure or kept at sub zero temps. I think the ultimate goal is to just let cars pump it without any modifications.

Wouldn't that be lovely?

Hmm, I don't know if that's possible or not to keep it liquid under low pressure without some degree of refrigeration. It has kind of a weird-looking phase diagram. I'm not entirely sure what its properties would be in the 2-phase region.

It is unknown why he even had that first experience on LSD. By his report, the experience lasted two hours and abruptly faded away. Even a small dose of LSD lasts at least six hours. It is theorized that it was something else entirely that caused him the trip, and that makes the discovery of LSD possibly the biggest coincidence of all.
#40 - anonexplains (06/25/2013) [-]
Pretty sure he took multiple table spoons of liquid L. The purest of the pure. "White on white", "Phamily Phluff", or "Swiss Crystals" as the hippies call it. He couldn't ride his bike home. Sounds like a blast.
User avatar #73 - Lambda (06/25/2013) [-]
After that first time, he tried an experiment, taking what he thought was a threshold dose. He was wrong, though, what he took was a very high dose. Resulting in his memorable bicycle ride. That was the first LSD trip of all.

I did some more maths to put it in terms of power per dollar (using your figures for power and density.) Your math was good btw.

Assuming (conservatively) that gasoline is $3.00 per gallon and LNG is $1.50 per gallon, the energy provided is 40.826 megajoules per dollar for gasoline and 58.932 megajoules per dollar of LNG.

This is exactly what wyldek predicted. A tank of LNG will have less range than a tank of gasoline, but equivalent distances will cost less running on LNG. Hooray!
User avatar #293 - Lambda (06/25/2013) [-]
Now I just have to figure out how to convert my car. Should be simple enough for a carburetor engine, the principle is the same: Mix fuel with air, ignite, and boom. The carbs would need to be modified to handle the gaseous fuel, a pressure tank would need to be put in to hold the LNG, and some special sort of regulator mechanism would need to be fitted in place of a fuel pump.

#198 - wyldek (06/25/2013) [-]
Yeah, but even if the cost/power ratio is better, you still can only fit so much of it in your car. So you also need to know power/volume.

Odds are it will be less power/gallon than gas, but better cost/power. So a tank won't get you as far, but the same distance will cost less.
User avatar #207 - Lambda (06/25/2013) [-]
I've been doing some research. Apparently the energy density is 55.6 megajoules per kilogram. Gasoline has about 45 megajoules per kilogram.
LNG has a density of 420 kilograms per cubic meter. Gasoline has a density of 719 kilograms per cubic meter.
The average size of a gas tank is 0.06 cubic meters. Gonna have to bust out the calculator for this one. So, an average gas tank can hold 1401.12 megajoules of natural gas. That same tank (that's a 16 gallon tank) holds 1941.3 megajoules of gasoline.
So, in conclusion: You still get more energy from a tank of gasoline. But, only about 0.28 times more energy. And if the cost really is going to be that low, then that makes gasoline three times the price of LNG, making it worth the conversion.
please let me know if my math is off, it's summertime and I'm not in math mode.
