    Demagnitize reception of radios

    Most people want a clear sounding reception on their radio, however I do not for obvious reason. How can I demagnitize the reception of radios. Any comments would certainly be helpful.

    Frequency generator to shut off street lights.

    Would anyone have such a clue on how to turn off the light-sensitive street lights? Light toches the photoresistor of the street light and the light goes off and vise versa. Light, I assume, is made up of waves and particles, so would any other type of frequency turn the light off? It is...

    43536 T 107 transistor

    This transistor I found in a light sensitive night-light. The whole circuit has only three parts; resistor, photoresistor, and a transistor. I would like a datasheet for the transistor,which printed on the transistor is 43536 T 107 (the "T" is like a smbol). I would greatly appreciate it!

    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

    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...

    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

    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. :)

    Help on reception of walkie-talkies

    I have a cheap set of walkie-talkies and I made an adjustment to add a electret condenser microphone. So, the reception is horrible (about 1 cm. range) and wondering if anyone knew how to make the range much larger. Thanx!

    Amplify

    I was wondering if anyone had a schematic that ampified audio input with a LM386 IC (or something close).

    Capacitor

    Is there a way you can check a capacitor to see if it is working properly? Just wondering. :)
