How to amplify osciliaton

You try to obfucate for NO reason, and as you continue you are boring and more and more ridiculous, why?

I heard there was a good theraphist for people like you. If you want i can take the number for you.

And it isnt "obfucate" it is " obfuscate".

I dont know what this circuit does, but it does something. That is more than Hurz does.

Try again, and be tidy in your work; This is what you have done so far; http://everycircuit.com/circuit/5566116402561024

Check what Billy beautyfied and now explain your theraphist what this curcuit is for. But please dont try to tell us what it is good for.

Yes, tidyness is a great help in seeing what is and isn't needed. hurz's accusation of obfuscation probably pertains to the mess, the components which aren't doing anything at all because they can't pass any current as they are (notably the LED), and to pointless things like 2 resistors in series. You can also try things like shorting out very small resistors to see if they were doing anything; you can always click undo if they were.

My mistake, the LED does pass current. It just doesn't affect the oscillation. It might make sense if the signal there was amplified, but it's smaller than the signal at the collector of the BJT.

I am not an engineer. I know that there are plentiful mistakes. It is just trying. I just dont understand why your comments are insulting, humiliating and doing nothing. If you think it is nothing , dont say anything. I told you before Hurz i dont want your comments. I would like to hear a fruitful comment instead of being insulted. I made this circuit going home from work on the shuttle bus . I just didnt care for some of the components. I just want to know why i cant amplify the signal with a mosfet. It should have worked i think. You keep talking about being messy. Cant you understand what is happening there? If you dont understand, that s ok. My bad. Then just tell me that you couldnt understand it and if i tidy it up i can get more help. That would be the normal way of saying it. You might be good at electronics. Obviously better than i am. But you just dont know how to act normally. Stop being just a nerd and start to learn to talk to people. Dont comment on anything i share here until you call this theraphist.

You must start on a level were comments are helpful for you, this is what i alread told you in the past. You build fantasy ciruits which have no function for nobody. Start on a basic level and you will get useful help, or proof you can talk with @eekee he started to explain you whats starnge in your circuit. Go ahead and show us some progress. In the past i tried that tooooo many times with no useful reaction on your side, because you are lost.

So you took a well known circuit and messed it up with all the useless components. You gave it a strange headline and what? This is whats left over if we do UNOBFUSCATE for you. http://everycircuit.com/circuit/5089316245340160

Hurz you came into the chat like this "You try to obfucate for NO reason, and as you continue you are boring and more and more ridiculous, why?" Offending and rude. Why? He/she is just a beginner, if they have refused your help, let them be on their own, not offend them for trying to expand their idea. I don't blame LeButch for having a bit of conflict with you. For you, methamafoz, I recommend thinking of your goal and where you are at. Lets say you have an oscillator for 100kHz, with a Peak to Peak voltage of 1V. I would try an Op Amp to amplify the voltage. If the wave has any negative peaks, use a capacitor after the oscillator output then followed by a voltage divider to put the negative peak in the positive voltage range, of course, if your power supply has the potential to go into negative voltage, then you do not need the capacitor and the voltage divider. Try different gains, depending on your power supply and the oscillator voltage. As others have said also, make your circuits as neat as possible, you never know when you need to improvise and you need to move all the components again and might cause a short or unwanted connection. Best of luck.

http://everycircuit.com/circuit/6515066408271872 There, try this. Also, I would use a MOSFET to limit current or as a switch in this case, not to amplify anything.

@sshssfun, lets see what your help brings for @methanafoz. Im afraid he will ignore you and your technical help. He already ignored @BillyT @abobaker help. In best case you will get a thanks. @sshsslfun, from were did you get the circuit you extend in your link, isnt it what @BillyT and I have UNOBFUSCATED for you? Was that for you so clear its this kind of 4component phase shifting oscillator behind, what @methamafoz posted? No the original circuit was total unreadable for you. Thats the methamafoz strategie.

Exactly as i expected, after we unobfuscated his circuit there is no discussion about this not working circuit, hes gone, cuz he dont understand anyway.

If hes gone either way, doesn't matter. This is an online community where anyone can read previous discussions and improve aswell as learn.

Hes is not here to learn as you can see from this thread already. You can be optimistic as its your first contact, but i give up long time ago. You should check the history before you judge. Anyway, who do you think you are little bastard telling me i dont want people learning? Bring 1% of knowledge i have put into this community and we talk in 5 years again.

I feel like I "build fantasy ciruits which have no function for nobody." The differences are I have time to look and see why it doesn't work, and I remember some stuff from reading about it years ago. I try to pay attention to comments, but sometimes I just have to leave it. The learning process is hard. :)

@methamafoz : Thanks for tidying it up. :) I can see what's wrong now. The FET is in common-drain mode, meaning it can't amplify voltage. Common-source is the usual way to amplify voltage, and almost always the best way with a single transistor. Basically, you want the terminal with the arrow to go to ground here, and put the LED and resistor between the other terminal and +V. The same goes for a NPN BJT. With a P-channel FET or a PNP BJT, the "common" line is +V.

@methamefoz: Common drain configuration can amplify current while keeping voltage almost the same. Make the resistor here larger to see that; it needs to be much bigger than the FET's own resistance. It works better with a BJT, called common collector. These are also called "source follower" (FET) and "emitter follower" (BJT).

Wow... I was about to suggest an image search, but so many images have the arrow direction swapped between P-channel and N-channel! Maybe it's something to do with the "bulk" terminal EC doesn't simulate.

Thank you @eekee for the time you took. I will do my best to improve my circuit with your suggestions. Lets see how it goes.

@eekee once BillyT had told me mosfets in ec have lower gain than normal. Maybe it is about that

@hurz i do learn by the comments. I just dont have as much time as you do for here. The only comments i dont learn from are yours. The more i try to be constructive the more angry you get. I dont really understand what is wrong with you. I told you a gew million times. I dont need your comments. You dont need to comment on my inquiries. And i had told before i am not an engineer. I am trying to learn by myself by trial. I have a job. I am busy. I dont have the time to respond instantly. If u have good fr u.

You learned most from my comments. So stop messing circuits and we are even more with you. BillyT and i had a lot to unwire what you have obfuscated

Your problem is not the oscillator, which you mess up, your problem is to make an amplifier, right? So why not start with this, if it after all your “im not an expert“ whining not to complicated http://everycircuit.com/circuit/4530124723847168

No my problem is not that @hurz. I want to use the signal it creates. The amplified signal doesnt have to have negative values.

“the amplified signal doesn't have to have negative values.“ start with the example section, you do not even understand the most simple things.

You dont understand what is written here. I dont need the negative value. Work on your reading skills

Or you are trying to quote what i say and change what i meant by cropping it

What negative values are you talking? You seems to be very confused. You do not know what you are talking?

Hello, were the voltages negative in my circuit?

So you dont know and answer with bullshit, your level of internet communication.
