    CB transmitter

    This project here, I have multiple questions. http://www.electronics-lab.com/projects/rf/018/index.html First off, the microphone on the left of the schematic. The V+ I'm assuming, is where the positive terminal of the battery is to be connected indirectly. The ground smbol is for the negative...

    Audio Amplifier from Scratch

    Thanks guys! :) I took Audioguru's advice and added a 10uF capacitor to to pins 1 and 8. That worked at pretty well. I also tried a 100uF capacitor, but it was just too loud/annoying. ;D I have thought of the Nightrider circuit, and it seems pretty neat and catchy. Although I hope Radio Shack...

    Audio Amplifier from Scratch

    Audioguru, I have trumendous news. I finally built the amplifier circuit since I found out all my answers. And my confindience of it working was 1 to 10 (least confideance), but I tryed. And what would you know, it work. I amplifyed an answering machine. The potentiometer work extremly well...

    Audio Amplifier from Scratch

    Hello Audioguru, You say to connect the negative terminal of the battery to the signal source. Is that the input source?

    Audio Amplifier from Scratch

    I see your point Audioguru, I accidently switched the terms around. What I would like to do is just amplify a speaker. Which is amplifying the input of the speaker signals, because speakers don't give off much output if not at all.(Correct)? I also added that I wanted to amplify a (electret)...

    Audio Amplifier from Scratch

    I plan to build my own audio amplifier circuit using a LM386 chip. However, I am in need of assistance. Here is the datasheet for the LM386 chip. http://www.national.com/ds/LM/LM386.pdf First off, I would just like to amplify the output signal of a speaker. If it is possible, I would like to...

    A Fishy Component

    Well, so I can make schematics from stuff I take apart. :D Then frame the shematic! ;D I wouldn't won't to brake it open, because I already kno what is in it. But I have broken into a silicon chip before I knew how they work.

    Electric Motor

    Audioguru, I see your point, however I have heard about capcitors that filter, such as in a rectifier (perhaps ;D), and also a tuning a radio with a variable capcitor. I know that if a capcitor is attach to an AC outlet, the capcitor charges and discharges rapidly because of the alternating...

    A Fishy Component

    Kain, I'm now pretty positive it is a surface mount resistor, because I have seen them on the printed side of a circuit board. ;) Thank you for helping :) (I don't like components that I don't know ;D)

    Electric Motor

    Whenever I take apart something, such as radio-control car, the motor is populated with capcitors. About three of 0.01 or 0.1uF ceramic capcitors are attach to the eletric motor. Does anyone know of this reasoning of attaching these capcitors?

    A Fishy Component

    What is SMD? ;D I am pretty sure it is a capcitor, and they usaully range from 16 to 1600 picofarads (which I just read about). Maybe it is a resistor, hence the labeling of "R". Thanks!

    A Fishy Component

    I have another fishy component. It is extremly small. The home page of this website has a background graphic of a pcb at the top-right corner. There is a IC chip and right below and above to the right is a bunch of really small black squares. When I look at a pcb, it labels the small black...

    A Fishy Component

    Thanks Kain! :D I think thats what it is. I frogot to add in my question that I took it apart and there was some kind of "netting". Maybe that is the quartz. :) And to add, its about 1/8 a inch in width. ;) Do you know the shematic symbol? ;D

    A Fishy Component

    My question is that on devices like radio controls, there is a silver component that is about 1 cm. tall and has the numbering of the radio freq. that it is supposedly to give out (such as 27.145MHZ). Does anyone know of this device? :)

    Physics of Semi-Conductors

    The physics of semi-conductors takes a lot of practice to understand fully. One concept I want to learn is the subject Newtonian. If anyone has some information on this (Newtonian) subject, I would be greatly appreciated. :)

    Blinking LED

    Audioguru, I was using a 9 volt battery so I will try adding the diode. I have 4001 diodes, and I'm wondering if they would work. I know how diodes work, but what do the numbers on them mean?

    Grounding circuit

    I heard that grounding the wire to your faucet is good idea for grounding. No matter where the grounding symbols are on the schematic, you connect all of them together, then ground them? :o

    Blinking LED

    MP, I have a question relating to microcontrollers. I have a vague definition of relays. I know that they have to do with the binary system, however whats confusing me is I heard they were transducers. ??? Is it just me, or do they produce an electromagnetic field to trigger something? From what...

    Blinking LED

    MP Thats what thinking about, Hotwaterwizard's schematics. If you or anyone else have blinking LEDs with microcontrollers, that would be great ;D. I am just getting into plcs, and microcontrollers. One other thing. The schematic that Hotwaterwizard post that involved two NPN trasistor I...
