Wireless guitar audio transmitter/reciever

Picture of wireless guitar audio transmitter/reciever
I've played guitar for a long time and ive always loathed all of these cords. I'd seen these wireless transmitters but they're always more than I'd like to spend so when i had a revelation on how to make one for $30 i just had to share it with the world.

Step 1: Get the supplies

Picture of get the supplies
you will need only a few things
1. a pair of cheap walkie talkies that dont have a timeout but do have noise cancelling
2.a guitar cord of decent length
3. a soldering iron/solder
4. universal screwdriver
5. knife
6. donut of your choosing
7. and, of course, DUCT TAPE

Step 2: Disassembling the radios/ guitar cords

due to the fact that i dont know which radios you're using, ill just tell you to remove the cover however possible, without damaging the board of course. remove all of the electronics and set them aside, be sure to also disconnect both radios and microphones. then cut the guitar cord in half, or to a decent length and strip both sections of wire for just under an inch.

Step 3: Making the transmitter

for the transmitter, first heat up the soldering iron. after that take one half of the guitar cord and solder it directly to the leads where the mic used to be. mine wouldnt stay soldered due to paint on the chip so i used some dual audio wiring, you know, the kind they use for stereos and taped it to the leads/ cord. you will need to make sure that it keeps transmitting so either solder bot sides of the switch together or stick something in there an tape it to keep it on. if you have a radio that automaticlly shuts down after a period of time the entire project wont work.

Step 4: Making the reciever

this is basically the same process as step 3 but with the speaker instead of the mic. be sure to reinforce it with duct tape or the solders will come undone, do this with both radios

pretty cool, you seem to know wireless things but do you thing that it would be possible to make a wireless jack to go into an ipod and then another into like a sound system? ex: i play a song or sound(if you know what i mean) and have the recieving end (that is most likely connected to a sound system) play the sound? im thinking of a senior prank already even though i still have 4 years to wait

if i understand what you mean, it should work, but you need to use the correct wires.the black wire inside is the right channel, and the brown is the left, orange is the ground. if you further info, there are diagrams online, and it should be fairly easy to hook up, tell me how it works out.
and the sound , is great ??

its okay, if you can use shielding to reduce interference, definitely do. also some more expensive radios have some form of noise cancelling. if yours do, enable it. overall, i would not use this for playing publicly, but its a lot of fun to use for leisure play or with friends. it's certainly a good way to understand all of the things that go to work in devices like these and how they can be modified or used for other purposes.
Can I use 3.5mm for mp3 wireless instead of 1.4 jack? Ty
Interesting build. Another method of getting a "wireless" connection for your guitar is to use one of the cheap FM transmitters made to plug into IPods, etc. If you get one that just has the 1/8" stereo plug, just add an adapter - 1/8" stereo female to 1/4" male mono. Plug the 1/4" plug into the guitar. Set the FM IPod transmitter to a clear frequency. Turn on your stereo, set to FM radio, and find the signal being broadcast by the little transmitter. Presto! You new have a wireless connection from your guitar to your stereo system. Only problem that occurs is if your guiltar pickups have very low output, then there's not enough signal to drive the transmitter. There's probably a way around that already posted on here, about how to use a pocket mp3 player as a practice headphone amp. If you put that between the guitar and the transmitter, there will be plenty of signal to broadcast to your stereo system (naturally it helps if you have a decent stereo system). Worked for me; YMMv.

Will it work? Yes it will. Will it sound good enough to use for live use? Nope. 2-way radios are not meant to handle the frequencies that guitars use, they are meant to handle voices, and they don't even do that good for voice. Good concept, and if you are just building for fun, that's great, but don't try to use it for a concert or anything like that. Also, in the US, using this is borderline illegal. Not sure about elsewhere. Good idea, but I wouldn't waste my money, since you wouldn't be able to make it sound good. Save up and get an AKG wireless guitar system if you do any type of performance. (and for recording, don't use wireless even if you have a good system!)

First off you can use the noise canceller on any decent radio or any fx pod to cancelled it. Or you can just play metal. And I can see no way in which this is illegal. I his replaced a Mic with a guitar and a speaker with my amp.
The noise isn't what I'm talking about. It's the frequency range that the radios transmit. (I suppose that if you are playing heavy metal, then the distortion doesn't matter... you really can't make it sound any worse in my opinion.) This would not work for any other type of music, and you are really stretching it for even for heavy metal. I'm not saying that the process you did with it is illegal, it's what you are using it for. And that is borderline illegal. Reason being, as long as you are using that channel, no one else can. This could be construed as "harmful interference". If you are a consumer in the US, using consumer equipment, you are bound by part 15 of the FCC rules and regulations which states that "your device cannot produce any harmful interference, and it must accept any interference received." Now are you going to get in trouble? Probably not unless someone complains. Even then, any decent lawyer could get you out of it, but personally, for the quality you are getting out of that, I don't think it's worth the risk. By the time you pay for lawyer fees or a FCC fine, you could get a couple really nice wireless guitar sets.

In terms of quality, I do professional audio, so I am a perfectionist when it comes to audio. From my point of view, the audio coming from this would sound like c***, but from my point of view audio coming from "Beats" headphones sounds like c***, so I guess most consumers don't have a very high expectation for their audio. :(
