[QUOTE=TNOMCat;45900582]OK so I have a question about radio. So if I have a relatively high frequency signal going through a wire, how would I broadcast it as radio waves? Or is it already radiating rf but with such a low power that it cannot be picked up by anything? Is there some really simple way to amplify any signal so that I can get more broadcasting range?[/QUOTE] It would need to be amplified and possibly sent through a modulator depending on the signal. However, what you need and how you do it (along with the type of antenna) depends on the type and frequency of the signal.

On Windows 8 it's been renamed Windows Defender but is common sense + Windows defender + MalwareBytes anti malware as much as I'll ever need in the antivirus department if I'm pretty careful?[/QUOTE] Unless you tend to stick around risky sites, it should be enough. You could also install Adblock and disable scripts as those are usually how exploits and such get through. You just have to manually trust sites to run scripts.

However, what you need and how you do it (along with the type of antenna) depends on the type and frequency of the signal.[/QUOTE] Doesn't the wire already act as an antenna? I've seen lots of radio transmitters that just use a random wire. And why would I need to modulate the signal if I just want to transmit exactly whatever is going through the wire (I'm not trying to receive it with something that uses FM etc) Also about the amp part, do you know any preferably simple circuits that would suit this purpose? optimal would be a circuit with 2 wires coming out of it, other one is the antenna carrying the amplified signal, the other wire is hooked to whatever wire is carrying the weaker signal (and preferably leaves the original circuit that has the weak signal intact so it won't draw too much power from it)
On my laptop it says "24 month warranty" But when I asked support they said "Asus warranty is only 1 year" Am I missing something here? Should I go down and have a chat?

Avira found an HTML hijack earlier today, and I had only visited pretty trustworthy sites (Google Hangouts, Pearson MyLab, BlackBoard Learn, Walmart, Amazon, and the product site for my surge protector). I'm running a MalwareBytes full scan now, see what it left behind, but I think Avira caught the most of it. I will be enabling click-to-run scripts, though. EDIT: Actually, scratch that last bit. Click-To-Run was enabled, and I've got Adblock installed. So this thing managed to latch on from straight HTML, get through Chrome's sandboxing, and evade every system I've set up except Avira. Interesting.

So I'm making blind assumptions. The wire does act as an antenna. But depending on what you need it to do, a simple wire may not be enough. Either way, the signal needs to be amplified. I'm not an electronics engineer though so I don't know how you would make one using off the shelf components. This is something your probably going to need to research yourself to be honest. Or at least would warrant its own thread.

[QUOTE=xplicitt;45898210][img]http://i.imgur.com/l9cJ7w6.png[/img] not trying to be mean, just cant draw for dick and keep in mind, mine is already disabled, so yours would say enable. it's backwards, you're enabling the option to disable directdraw.[/QUOTE] Cheers wonder how that option got turned on.

[url]http://makezine.com/projects/make-38-cameras-and-av/raspberry-pirate-radio/[/url][/QUOTE] Yeah I've read about this. The Pi is digital tho, so you can only broadcast square waves (which is bad unless you want to jam stuff and/or summon the FCC :v:). But at a high freq with frequency modulation its apparently good enough for fm receivers to pick up.
Anyone know of some quality 800+ watt PSU's? Last time I did thorough research was 2011. What I got was: look at Seasonic, Corsair, maybe Antec, and some other stuff.. Oh, and I'm going to build a PC with the power supply at the bottom (never done it)..

Well okay, maybe I did overkill research last time. Finding a suitable power supply was not difficult. I'm looking at: [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16817151108[/url] Well, didn't update the page and assumed auto-merge. Whatever, anyway, maybe I don't need 800+! I'm pretty clueless on how much power new CPUs and GPUs draw. I saw some wonky numbers which threw me off. For instance, I'm building a workhorse desktop and read that the i7-4790K could draw like 300 watts? Haha, I honestly have no idea. And that the mid to high end GPUs might draw something like 250 watts. To me, it sounds preposterous, but I still have no clue.

What GPU do you have?
Okay, sounds reasonable. That's more like what I remember. I'd be using a Radeon 6970. I have a 600 watt power supply already... so, cool.
Yeah, that sound be fine as long as it's a decent brand.
[QUOTE=Bat-shit;45899534]I got this weird pop-up on my Google Chrome's upper-right corner saying "Your internet connection is being managed/controlled" (rough translation) And there were two options "Restore settings" or "Change settings", I pressed restore. And now strangely my font is slightly different on facepunch, almost like the zoom is slightly off but it's not that. WTF?[/QUOTE] Oh god, anyone? This slight font chance in Facepunch is really irritating. :v: Plus I don't know what the hell that Pop-up was about.
how do i cable management I'm getting s fully modular PSU to replace my current non modular one. I have a case with the sleeves too.
[QUOTE=Bat-shit;45905285]Oh god, anyone? This slight font chance in Facepunch is really irritating. :v: Plus I don't know what the hell that Pop-up was about.[/QUOTE] The font is directwrite being enabled In chrome go to: chrome:flags to the directwrite option and disable it
[QUOTE=Original User;45906460]how do i cable management[/QUOTE] I just shove unused cables into the empty optical drive space (I have no drives anyway), or use a twisty tie thing to latch them to any out of the way holes or something. With nicer cases this is probably less relevant.. Twisty tie things are your friends (like those plastic or Velcro ones that come with certain PSUs). I sometimes tie cables together to get it out of the way of the CPU fan or something, like if there's a case fan that needs molex. Why am I saying this D: . It just seems like common sense, unless you're asking for something more elaborate.
Ugh, it's been a while since I last reformatted and reinstalled Windows on a PC, would appreciate if anyone could help me out asap! I recently installed a clean 250GB SSD (switched it out with the mechanical one) and some 4GB ram for my Asus N53S laptop. I then inserted a bootable USB drive and booted it up, but POST says "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system". The disk seems fine on my desktop PC, tho. Any ideas?
Um, well you need to set the boot priority or better yet, use the boot menu and simply select select the USB stick. For your bios, it could be F8, F10, or delete. When I don't know, I typically mash all the function keys during boot. If you've used the bios before, it shouldn't be a hassle. But if you haven't, and didn't find the boot menu (which is just a list we're you choose, "boot from whatever drive"), just poke around until you find something like "boot priority." Basically it will list all the devices and non devices the machine will attempt to boot from in order, the top being the first.

So I'm wanting to record gameplay clips in 120 FPS, but using fraps seems to always lag somehow. Would it be useful to get a capture card or something?
[QUOTE=Mooe94;45909594]I've actually done this already, doesn't work.[/QUOTE] Oh, okay. Well maybe the USB stick wasn't prepped correctly. I am just going to be presumptuous or whatever and offer another solution. [url]http://rufus.akeo.ie/[/url] is a reliable tool to use.

[QUOTE=thefreemann;45909656]So I'm wanting to record gameplay clips in 120 FPS, but using fraps seems to always lag somehow. Would it be useful to get a capture card or something?[/QUOTE] The biggest problem with Fraps is that it runs entirely off your CPU. Capture cards are better, because they have all the encoding hardware on the card itself. Personally, I use OpenBroadcaster. It usually runs pretty well, and it's a bit lighter than Fraps. It's also free, and you can stream with it. Anyway, give some other software a shot and see if one works better. If not, then you might want to look into dedicated hardware.
Yeah, OBS is a good program. Fairly lightweight and quick to start. Another program is XSplit, but it's not worth really mentioning because it's got a longer startup process and is subscription based.
[QUOTE=thefreemann;45909656]So I'm wanting to record gameplay clips in 120 FPS, but using fraps seems to always lag somehow. Would it be useful to get a capture card or something?[/QUOTE] Do you have an Nvidia card? Shadowplay is grand.
Nope, AMD Even if I did have Nvidia, I don't believe Shadowplay can record more than 60 fps? I might be wrong but i'm just guessing
Anyone currently making use of a 4k monitor/TV? If so, would you say it's worth the result, and what GPU are you using alongside with it?
