I have made many circuits by following schematics before, but i have never really made my own, i can read and build but not create, basically.

i have a 30v, 10a, 300w military generator, its very small and i would love for it to have one or two 120v plugs on it, any ideas how to go about a circuit to change the 30v to 120v, and the dc to ac?

heres the question,

a police officer holds a radar thats signal travels at 3 x 10^8m/s at an approaching vehicle. The echo is received 3.333 x 10^ -6s later, the machine waits 1.728s and then fires another signal, the echo of this signal received is 2.933 x 10^ -6s later, the cars speed is calculated and immediately displayed on the gun, what is the velocity of the vehicle in km/h?

Thanks

I am looking to buy a set of subs, and i want to keep it kinda budget, cause if i blow them on my first try, i dont want a big loss, i want to learn one step at a time with car audio,

anyways, i was looking at Kicker Comp's, or MTX terminators, but then i stumbled across a new set of Clarion SWR1252 subs, and i really like those, there cheap too,

anyone have any experience with any of the subs above or have any other budget suggestions?

I want some music, like a rap style, ex. Songs like remember the name, old times sake, or even the start of buck in here, like that style rap, with no repeating chorus, like a rehearsed freestyle i guess :/ any help is apreciated :)

i just got this iphone, it was used a little before, like 2 months, anyways, the two speaker ports on the bottom, sound only comes from one, is sound supposed to come from both? if it is i think my right speaker is broken?

ok, I have a 17.5" DV7 laptop that chews battery like candy, it lasts about 1:30 hours, when it was new i got 2hours, anyways, my battery is shot, and i need to get a new one,

they have 6-cell, 8-cell, and 12-cell and a 6-cell Long Life 3 year battery,

whats the difference between them, and would it be better to put in the extra 20$ and get the long life battery with the 3 year warranty rather than buy a new one evry year?

thanks,

I have a Gold 1979 Trans Am, Olds 403,

It is totally original, origional paint, body, interior, even wheels, NO RUST, and fires and runs like new, it has about 80K on it, a mix between city and highway, this car has had it easy, it was run from 79-83 then it was stored for years until 2003, then for more years until 2008 untill today, so only 6-7 years on the road, and only in the summer, this thing has never seen rain or snow before, it just sat in a heated garage under a cover for years,

so, my dad bought it for 10,000 new in 79 when he was 17, we were wondering what the value of it is today,

long story short, i mixed some laquer thiner and water, the seperated like water and oil, which one is wich, i have no clue, so which floats, and wich sinks,

The sources i have are Canadian Tire and Home Depot, so i can get my supplies there,

anyways, i need to know what i need to braze, i undestand i need to heat metal then add filler, but what filler is that?

i want to use brake line, wich i can get at CT, so what filler rods do i buy?

i know i need MAPP gas wich CT also sells, any help is apreciated,,

Ok, i got a smartphone with windows mobile 6 on it,

i used to play need for speed 3 on win 98 when i was little, and that computer only had like 32mb of ram and a very low end CPU,

so can i put need for speed on my phone wich also runs windows, do you think it would run it? or how i would go about installing it to try it?

I dont like flip phones or slide phones, i like a one peice bar phone,

i like it to have a flat back and thin profile, what would you guys reccomend, i was looking at somthing like the Samsung Blackjack 2, but i dont like the bump on the back where the camera is, i want a flat back,,

ohh, and it needs to be under 200$ used, thanks,,

thanks,

Ok, i want to get an HTC Diamond on my Bell/Solo network, i run solo, but i want a phone bell carries,

the HTC Diamond to be exact, the guy at solo said if its HSPA compatible, then itll work, but all i see is HSDPA, will the phone work or what??

I currently run on Solo with a crappy Krzr phone,

anyways, i know solo is a branch of bell and any bell phone works, (i want to get the blackberry curve)

but what carrier in the U.S is like bell, because bell uses a DSIM wich is a digital sim card, so i have to get the lady to switch it on the computer,

like i think the Fido/Rogers is similar to T-Mobile over there, so whats bell?

Ok, so i have an HP DV7 laptop, and the old battery went, it would shut off randomly and such,

so me trying to save 140$, i bought the upgrade replacment cells and soldered up a new pack that works,

i have battery bar pro, and at first the battery wouldent charge, and got stuck at 86%, so i flashed the BIOS, and it fixed that,

but my battery bar says my batteries are at 58% worn out already!!! i bought these things new! my old ones were 62% worn and they needed to be replaced,

this is the first charge and they have not been cycled yet, will this change once they cycle, so this could be a false wear reading?

I was looking on Jegs.com for headers for my 1979 Trans Am, and all i see when looking into sections and the 1979>Pontiac>Firebird>Parts section, there is no Trans Am section where you choose the car type,

I have the 403 V8 model, (i don't know if they made them for the firebirds), but are the parts interchangeable between the two cars? like if it says it will fit a 1979 403 V8 Firebird, will it fit the trans am also?

are there any trans am specific sites i can get parts off of, mainly looking for stainless magnaflow pipes, mufflers and Hooker Headers, and maybe an electric fan to replace the engine fan,

I have an HP Pavillion DV7 with an Intel Centrino CPU,

i want to upgrade to either an Intel Core 2 Duo CPU or a Core 2 Duo Extreme CPU, but i am curious to know...

are laptops for CPU's and desktops the same? like the sockets and the cpus themselves?

and does my CPU actually come off the board, or is it on there for good?

and any other useful info i will need for the swap, thanks guys,,

Hi,

I have a HP 18" Pavillion DV7 Laptop and i couldent be happier with it,

i have windows Vista Ultimate, Photoshop CS4 Extended edition, and other power-hungry programs,

the computer is great but the CPU does get a little hot and i use these programs daily, it has a Intel centrino Dual core 2Ghz CPU,

i was thinking of putting in a Centrino 2 Duo 2.5Ghz CPU, would it just pop in and would my computer motherboard be able to handle it?

also, could i switch the graphics card as easy as the CPU, does it just pop out? or is it hard soldered onto the computers motherboard?

i have a 6 week old Maltese - Apso Lhapso (or wtf its called) puppy, all night last night he whined and kept me up, any ideas to make him sleep a whole night?

I have a new HP Pavillion DV7 laptop, and i wanted to use it also as a screen for my xbox and ps3, it has a VGA and HDMI ports on the side, but could i go from my ps3 HDMI into my computer to display it on my computer screen? Is it possible, and How?

I have a 195? Ducati bike, its sitting in my shed and i start driving this year so i want to ride it, but it is missing parts and it need a total restoration. I have tons of money to dish out to get someone to restore it, but i wanna get some of the parts myself. I heve the serial # off the frame and i got 1 off the engine. Where do i put these serial numbers to see either what kind of bike this is, or to get a parts list for the engine to purchase new parts. Know of any good restoration shops? For a decent job at a cheap price? I live in Canada, Ontario, Niagara falls to be exact, do u guys know of any shops within 4 hours of me or do u have answers to my serial key questions? ,Thanks,
