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!

I am wondering if it is possible to send an arduino information wirelessly. Basically i want the wireless reciever to be the sensor and feed the arduino the information from my computer wirelessly. please any help at all of how this could work or other ways to make this possible would be awsome. cheers.

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.

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 donâ€™t know much about these types of controls and I looked through the manual and canâ€™t find anything to help. Is there something wrong with the controls or is something else going on? Can anyone help?

I am not trying to be babied or anything just need just basic advice. I picked up a few books on hobby electronics and want to get into it. For the first project that is not a "book" project I want to know how to use a small DC water pump to power a backyard fountain. In an Ideal world the pump would work from 100m+ away but this might not be a reasonable request. I purchased a pump and this is it:http://www.ebay.com/itm/Ultra-quiet-DC12V-Mini-Brushless-Motor-Submersible-Water-Pump-3M-240L-H-New-KN-/221703041910?pt=LH_DefaultDomain_0&hash;=item339e87f376 Very simple. I want to plug and play into a transmitter and a receiver. http://www.ebay.com/itm/DC-12v-10A-relay-2CH-wireless-RF-Remote-Control-Switch-Transmitter-Receiver-/171743350808?pt=LH_DefaultDomain_0&hash;=item27fcb39018 Will this system work? The way I understand it I need to connect a 9 volt battery to the receiver and I am assuming its soldered in. Then I can run wire to the motor directly. Am I missing anything here - I know this is very amateur but I am never done electronics stuff before. I will be taking a few community classes in the summer which could prove interesting. What else do I need to do this? Is there a plug and play system (receiver / transmitter) that would work easily?

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!

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?

I need a lightweight way to locate an object that has dropped from altitude and could be 30+ miles from my position. I was hoping that there i a simple, relatively cheap GPS transmitter/receiver system I could attach to the object. All it needs to do is transmit its coordinates at a regular interval, 5 to 15 min and have a range up to around 50 miles. Can anybody point me in the right direction? I have an old cell phone with a GPS in it. Is there a way for me to utilize this possibly? Either taking out the GPS unit or making use of the phone as-is. Or if you have an alternative means for locating an object at distance feel free to post that as well.

I need something simple to transmit pulses 2-3 meters to a receiver The transmitter will output a pulse every few seconds, transmit a small burst at X frequency. The receiver then outputs a short high pulse/outputs high for the duration of the received pulse. I want this to be as simple as it can possibly be, cost being the primary restriction and power usage being also of fairly high importance, so please no suggestions of Bluetooth or xbee type systems. It does not have to be a radio based system, however it needs to work without line of sight and of course without connecting wires. If it helps the overall aim is a 'safety signal' that will set of an alarm at the receiving end if several pulses are missed Anyone? EDIT: To clarify I am looking for simple, like really simple. So the transmitter is just a resonator and antenna. What I need is a simple receiver that will respond to a specific frequency, on or off. Does such a thing exist?

I know a fair amount with electronics, so i was PRETTY frustrated when i looked around online for a method of rangfinding that i could build into a small device. I have been wanting to have a project for awhile, so i am not just going to buy one. Anyway the inspiration comes from me and my dog, you see, hes a Jack Russel, and very eager, he loves to chase rabbits but i can never find him after he has run off into the forest, by that time he is too far away to hear me.I want him to chase rabbits because he loves it, but i can't use a lead because it gets caught on everything(Trees, plants, thorns and general vegetation).So i had an idea, if i could just have a device that would tell me how far away he is, then i could just use that to work my way towords him.The process seemes quite simple to me, give him a transmitting collar, and have a device that recieved that signal, and could use the basic distance = speed x time sum to work out how far away he is, then display it. Apparently, either nobody has ever tried this, or i just ain't searching for the right thing.I know radio waves seem to be optimal, seeing as he won't be more than 1KM away from me, but again, i don't really know where to look to find the parts, or how to build the thing in the first place. So please, if anyone could help me out, please do.My physics teacher is a real **** and refuses to help me.So you guys are all i have to ask. Thanks. /James PS: My dog would be REALLY happy too, he hates being on a lead all the time, and if i could get this done, i will post pictures of him, apparently hes really cute.

I am trying to make a very small receiver and transmitter from scratch to remote control many very small devices, specifically movement. the transmitter has to be an integrated circuit, but on a scale that is not sold commercially. this may be a bit vague but could anyone give me schematics for such a thing? keep in mind, i need 6 channel control and i might have thousands of separate units i have to control simultaneously. also if anyone can help with make the transmitter work with a computer, so that i can program all the functions for each of the machines from a computer, it would really help. Thanks! (p.s. i can't be much more specific)oh and i have all fabrication equipment i need from photolithography as well as atomic force and scanning tunneling microscopes for building things on that scale, just to give an idea of what scale i'm talking about. (the reason i'm asking for help is because i'm trying to incorporate my research with something outside my field and electronics is not my speciality.)

However, I don't know how the signal pin would work, but it would have to in order to get the right direction and stuff. Do you need a special shield for this?
