Ha, ha, ha. More likely by age her grandfather. I love all my grandchildren equally -- even those I don't speak of .

I love all my dear families including my son's stepchildren and grandchildren

 

I can c that it won't b easy 2 get u guys 2 help design a circuit but can u tell me what the language is 4.

Getting help here couldn’t be easier. If you feel like you haven’t gotten what you want it’s because you still haven’t told us what you want the solution to do. Vague notions aren’t enough, you need detailed specifications. We could even help you define those if we had a freakin’ clue what you intend to do. We’re over 40 posts in and still getting nothing but crumbs.

 

like this?

if this is what you need, keep your money, you will need it for the breadboard and components.aliexpress, sketch it out, give it a test, if it all works, fivver is a good place to get your circuit diagram turned into gerber or eagle files,id pay a max of $40 for circuit if I wanted it put to gerber or eagle, these are virtual copies of a finshed circuit board, then you can get afew prototype boards printed off and tested.

if your new to soldering id recommend though hole components,very easy to work with ,any other issues you could try doing to a local makerspace for help and learn some new things.

please do not give away you money, with $200 and some shopping around, aliexpress, Chinese pcb manufacturers , with the cash id expect to get a finshed design and about 100pcbs with all the components unsoldered.

Also not sure this is a troll or you struggle with the explanation.but everyones good atleast one thing, me theres parts of electronics, I struggle with however theres other parts which I don't, everyones at a different level, but how can we climb if no ones going to show us how to take the first step.

 

Nothing is going to happen....until you explain in some understandable language......what you are trying to do.

It's that simple. We don't have a Carnak forum here.

As wayneh says..... after 40 posts.......put up or shut up.

 

Hi people thanks 4 being so interested I love this place. But as u can tell I am a total tourist. Don't speak the language. I have been looking at these circuit schemes it truly is a different language. I can c that it won't b easy 2 get u guys 2 help design a circuit but can u tell me what the language is 4.
So can I take a circuit diagram 2 a commercial circuit board printer and they print me what u need or is there many other stages in between
Do I have to design the physical look of the circuit or is the diagram enough?

Is it possible 2 design a circuit on paper with out building it first and then hand it over to some one to build and it will work?
Or is it that you design it then build it, it doesn't work back to the drawing board, tm back and forward until it work?

First, you'll receive a much better reception if you stop the text-speak. Use full sentences.

For anything more than the simplest of circuits, the usual process is to design on paper (or directly in a schematic capture program), simulate or breadboard the circuit to verify it behaves like you want it to. Layout a printed circuit board with the circuit that also reflects the mechanical aspects of your design such as how it will be mounted and the shape in needs to fit in your enclosure and how it will mate up with the connections to off-board components. Then you either make the board yourself (whole other subject) or you send it to someone to be fabbed. Then you populate the board and test it and then assemble your final product.

In general it IS an iterative process, but you want to put a lot of effort up front so that the iterations involve as few PCB fabs as possible.

 

Ok thanks for all advice guys will take it on board no pun intended

 

How do you plan to distribute that £200?

 

When I design an analog circuit I draw it in LTSPICE, a simulator program, and test it to the extent that I can. I then breadboard parts of the circuit I am unsure of and test them. When I am satisfied that ot has a chance of working, I design a PC board and make a prototype. If that works, and I need several of them, I send it to a PC board house to manufacture a professional board.

It is not a process that I would do for anything close to your price.

ok thanks everyone very helpful

 

I've done this before to remove 60Hz. Before I even will discuss the circuit, I need the original poster to CLEARLY state what information he is looking for in the "return" signal. I've read through the ENTIRE thread (pretty much a first for me) and I am as unclear now as to what the goals are as I was at the first post.

Maybe he's building a crumb detector? And this thread is the beta.

51+ posts and people are still posting. I guess it worked.

Thanks guys I real like your community I think i an in a bit over my head so i going to read about how to make circuit diagrams and speak your language and come back when i can express clearly what I need help with. Thanks for your help, jonty. I love this site u all seem very knowledgeable

 

Welcome to the club. Our language is plain English.
You still have not stated what is your objective. Forget the gobbledygook about echo cancellation.
Tell us what you are trying to achieve, not what you want to build.

OK so our band plays live music and we record or performances so I need 2 build a device that can cancel out the very high pitch frequencies that come from imperfect sound equipment so that our recording sound great. So a circuit that can remove certain returning frequencies leaving the music intact

 

Are you talking about acoustic feedback which is also called howlround ?

Les.

Les.

Actually it's not the feedback it's a hiss that is the problem

 

Finally! If you had told us this in the original post we would have discussed multiple approaches, none of which would be anything like you have been asking for.

Your best bet is to find the piece of equipment that is causing the hiss.

Let's say I want 2 build circuit that can remove a certain frequency omitted from the original source on is return but leaving the fabulous music we play intact. Does that help?

 

I know what u gonna say y o y o y did u not say that in the start an y u insist on speak in txt SPK it v annoying an such. But hay u only live once yolo
