Hey. Ok, i am a member of another forum(www.aaroncake.net), and this person asked a question about a digtial wireless transmitter. Here is the link; http://www.aaroncake.net/forum/topic...=Sound%2FRadio

If you have an account there, please help him. If not, you may tell me, and i will post the solution. Don't worry, i will give full credit to the person who gives the solution. Thanks.

 

Why not have them register here and ask? They might get a response faster.
And they can search for wireless here. There have been many threads on it.

 

Having read the thread on the other board, if I understand it correctly:

1 The guy has to build some remote control device.
2 He has limited time to complete the task.
3 has limited knowledge.
4 He rejects the idea of using a remote control from an exixting toy/model on the grounds that such things are not obtainable where he is.
5 Because a built-up system is not available, he wants to build something from scratch.

If a made up system is not available, where does he think he can get the parts to build a system with his limited knowledge in the time available?

He wants to control a robot in a tunnel by radio.
He may be on to a loser here, radio does not propagate well in tunnels.
There is an effect called "waveguide below cut-off", whereby the tunnel will just become an attenuator and the radio signal will quickly disappear.

Best solutionin the circumstances, use an umbilical cable to control/power the robot.

Which is one of the main reasons that type of system is used on sewer/pipe inspecting camera bots. That and it allows a messenger cable by which you can haul the bugger back when things go awry.

 

ok, i will just post a link to this page when i get time.

 

It's people like Teamer who get my goat,they come on these boards and expect others to do their work.

 

Who is Teamer?

Yes, i don't like it eather, but it is our civil duty to help geek-kind.

 

Sounds like a another "omg I'm failing my course plz help" posts, I really can't be bothered with thouse :yawn:

Yes, that is the thing that pisses me off the most(please excuse my language). I dont understand why they are taking the course, if they can't handel the work. If they would just pay attention, or get notes from a friend who is willing to giveup their hard work. This world is defective. I wish we were still in the good ol' days where people had to know how a computer worked, inorder to use it. Or you have to know how radios worked, if you wanted to listen to BBC. People need to learn AND REMEMBER!

 

I know how you feel, however I don't quite agree with you on this statement. Think about this the next time you ride on an airplane, drive a car, use a cellphone, ICs, or even your computer. Very people probably know exactly how a automativetransmission or differential works, or the transceiver circuits in a cellphone, or the silicon in an IC, or a jet turbine.

However, you may find that many people who don't know how things works have money and know how to use it. Them buying stuff drives down the price so that those of us who do know how something works can buy it and not have it cost as much (like computers, remember when they were $$$?)

My take on it is...if you have no idea how it works...don't try and build it! Feel free to buy it though, just don't stick your head or hands into it.

 

i think it would be better for everyone to just ignore post which they don't have intention of helping instead of complaining that they should have done this or that.

but that's just me

 

I didn't mean all of that. I know what you are getting at though. I just ment that it makes me so mad when people refer to the computer system as "the hard drive", or the processer as the "Brain", etc. But point well taken. You are right, that would suck!

Yes, but most people here have nothing better to do!

 

no it isn't. That guy is obviously too stubborn/lazy/inexperienced to ever be able to successfully build and debug such a circuit, so why would I bother wasting time trying to "help" him (read: doing his work for him)?
