Hook up stereo speakers to computer for surround sound

Alright, if theres already an instructable on this, I apologize, and could someone point me to it, otherwise, here's my question: I have a set of stereo speakers, the ones with the clips that you use to hold in the wire, so it has no plug. The only stereo set I have has no outputs, no white and red RCA jacks, or anything, and I do not have any other reciever. Is there any sort of adapter I could buy or build cheap (easily, preferably) to let me plug two of those into a standard 3.5 mm miniplug? my goal is to use those as rear speakers for my computer's 5.1 surround, as they have good base and treble, and my 2.1 channel set that I was using there crapped out. Thanks!

electronics remote control

Could anyone suggest how to build an electronic system for using a radio signal to turn on and off another circuit. what i mean is a transmitter with a button you could hold and press a switch and a reciever in the circuit you want to switch on and off which prevents power reaching the circuit unless you are transmitting. i would want to be able to transmit over atleast 20 metres and through thin walls, aluminium foil and clothing. thanks.

Can anyone help with my RC problem?

I have these controls http://www3.towerhobbies.com/cgi-bin/wti0001p?&I;=LXLDP9**&P;=MLOn the receiver end each channel has 2 negatives and one positive so you can switch polarity. My transmitter is not doing anything on any channel and I get constant current flow in one direction even when the transmitters off. I don’t know much about these types of controls and I looked through the manual and can’t find anything to help. Is there something wrong with the controls or is something else going on? Can anyone help?

GPS reciever from cell phone!

Okay, i just got back from an air force base on a extremely classified training mission. but while i was there i learned a little known fact about a device that almost EVERYONE has in there pockets right now! well let me first tell you about a law that was passed somewhere between 2000-2005 that states " all cellular devices produced after this date must have a Global Positioning Service "GPS" device/module installed". so all post millennium cell phones have GPS in them and enabled for mostly federal uses. Your cellphone service providers such as Verizon have barely caught on to the trend and realized that since they already have a virtually unused GPS device inside why not utilize it? so they added a GPS service to it. thought not bug free, it is and amazing device for its size. it can give you position, speed, and altitude! so my question is as follows... how in the heavens can we "extract" and "utilize" this chip from our old our spare cell phones? this is possible but how? possibly paired with and Arduino? if anyone has a degree in engineering or a local library and the ingenuity to reverse engineer a mobile device, then the possibilities are endless! this is up to you instructables community!

IR Robot Control

The cheapest way of wirelessly controlling a robot is IR, right? I'm in need of help for a schematic for an emitter and a reciever (this will be my first IR project). Please don't tell me to google it because I've been looking around and all I've found were vague schematics. I'd probably want to use a 555 timer for the emitter, but the schematics were vague again. For the reciever would I have to use 4, along with 4 emitters to drive 2 motors independently? As in Motor1 front and back, Motor2 front and back?

fiber optic transmitter and reciever booster

I am a hobbist/inventor/sculptor/geek. I am looking for plans or a kit to build a fiber optic booster transmitter and reciever. Or even a unit that can send and recieve data and video signals. The signal must be able to travel a minimum of 300 ft. I am trying to build a submersible rov that I can afford. The other option that I might have is a rf to fiber optic converter. Would anyone be able to help me out?

Bought a Pro Membership for a present; recieved no confirmation and they didn't get the membership!

A couple days before Christmas I bought a pro membership as a gift for a family member. After I clicked purchase the site took a long time loading and then returned me to the main page. I checked my bank statement and the credit card went through; I assumed that the gift transaction had been processed. However I recieved no confirmation and they recieved nothing from instructables. I already e-mailed service@instructables last Friday and got no response. What's next?

I got an idea

How about we have some sort of Instructables year end awards and or hall of fame? Rate this forum if you think its a good idea. Something like this: Hall of Fame: One induction per month, selected by Instructables staff. Users to be considered must be nominated by a minimum number of people (7 for example) Year End Awards: Awarded at year end. Users are voted on, however there are first nominated for certain award by a minumum number of people (7 for example) Suggestions for awards: Coolest Most Helpful Most Popular Most Dangerous Funniest Hall of Famers recieve no physical prize, but are allowed to add their instructables to Hall of Fame group, and may recieve special avatar (see Kiteman) Year End Awards recieve t-shirt (maybe) and special "medal" placed on their orangeboard

I checked my settings and they still show that I want to receive notifications.

Cordless Telephone Bridge

I'm trying to figure out how (or if) I can use an old cordless phone as a tranciever, wiring in an rj11 jack to the phone's reciever to essentially make a cordless phone "bridge" so that I can use my desk phone in an area without phone cabling by plugging it into the cordless phone's reciever. I've tried the phone over power adapters and haven't had great luck with 'em, so I'm trying to think outside the box. Anyone have a suggestion or two?

Freescale Programming?

Out of the many samples I recieved last week, the freescale MC908JL8MPE is one of the few that I like the look of. Its a beefy PDIP with 28 pins, unlike the many TQFNs I've recieved I could actually solder this (well no need as it fits in a breadboard). But my problem is, there doesn't seem to be many easy-to-follow tutorials for programming these microcontrollers. The only simple solution seems to be to buy £100 programmers.. which I'm not too keen on. Is there a simple way to program them via parallel/serial or maybe using my usbtiny to program an atmel chip to program the freescale chip? Thanks.

Grech contest winners declaration

Hi everyone, I recently won 1st prize in the green tech contest, and about a week after the win I contacted instructables to see if I needed any forms to recieve my prize. They said no. After two weeks and still no prize, I examined the rules and found I needed to sign a winners decleration form. Instructables made an error, and now I can't get ahold of them to give me the form. Can anyone out there help? I don't know how much longer I have before I'm unable to recieve my prize. Thanks so much, Joe J.

After all this time I still receive the newsletter only on my hotmail only. I've tried everything I could think of: to change the subscription at the bottom of the newsletter I recieve in hotmail (but it lets you change everything but the email itself, so...), I changed the email associated to my Instructables acct.
