Well since you addressed me

Thanks MP, I

Well, why not start from the beginning to learn how a TV set works? You know this is where it all begins in the set! And then proceed one step at the time. Or (if you don

Yes, and I was re-routed to some other site with lots of trouble. The

The hardware is usually some form of attenuator to set the input range of the signal to measure. Next stage is the soundcard in your computer, and that

Hi Laurent, Welcome to this forum. If you want just the receiver (tuner), you can pull one out of an old set. They usually look something like this:

Bikerman, Got yourself a BOSS! Well, congratulations! ;D ;D ;D About T1, I think you are right there is no description to be found here. Maybe an e-mail to onsemi will get you the data for the transformer. If you are lucky they might send you some samples of the MC33374 also. Please post the result if you get it the info.

Hi Guys, I don

Hi CRE, As far as I know they are correct since I have encountered them both on many occasions.

Audioguru, It

Trebla, Yes, I think it

Hi Jeff, Do you just need a circuit to open and shut an electric valve or should there be some kind of sensor to control the valve?

Yevgeni, This document describes the hall effect : [attachment deleted by admin]

To you mean an attenuator for the input?

Hi Tommy, Welcome to this forum. Are you referring to any special motor application? Can you describe what you like to accomplish with the motor circuit? Usually there is no reason to involve any microcontroller to control a motor.

Hi CRE, They both work fine, here you can try different color codes: http://www.electrician.com/resist_calc/resist_calc.htm

Here is some facts about Hall effect switches : [attachment deleted by admin]

Yevgeni, While you are calculating the series resistors you also know the currents so just sum them up and add some headroom and you have the value of a suitable fuse. Put it in the positive feed line close to the source.

Bikerman, ...long time no

Trebla, Does

Audioguru, Schiller, Yes you are right Audioguru, I

Hi schiller, Welcome to this forum. If the motors are pulling any load and you want to control the rpm resistors or rheostats is not the best solution. Resistors are not very efficient in a motor circuit and besides the heat losses it is not possible to keep a steady rpm. The best way to do it is PWM (Pulse Width Modulation), there are many ways to set this up: Here is a few: http://www.electronics-lab.com/projects/motor_light/003/index.html http://www.electronics-lab.com/projects/motor_light/033/index.html http://www.electronics-lab.com/projects/motor_light/038/index.html If you don

Hi Tubby, From what I know about antennas the best directions should be north / south (broad side) with your type of antenna.
