12412, I agree completely, you are absolutely right!

Thanks MP, That makes a lot of sense! ;D

Dazza, aren

Dazza, Man, there are lots of things I don

FireFly, If you have the datasheet for the cap often there is a layout that can be used for drilling the pcb.

Have you connected to the soundcard successfully? Have you tried to alter the controls of the on screen oscilloscope?

MP, I agree 100%! Kumar, If an SMPS would have all these drawbacks and problems you can ask yourself: Why do we have harddrives, CD Roms, DVDs and half a dozen fans in the computer when the SMPS just don

Velleman has a kit with many nice options at a very reasonable prize K8055.pdf

OOPS! I have missed that one big time! :-[ Sorry for the inconvenience. Please let me know if there are any more errors and I will edit and repost a correct circuit guys!

Thanks Audioguru, That

Dazza, Yes a big cap is expensive and a microwave cap is rated for high voltage but it

PhuocTran, Does your soundcard have a line-in connection? You will need some kind of attenuator to reduce the input signal and to protect the soundcard.

absolution, I was just about to comment you

Suren, Here are some low component count FM receivers. http://www.elfa.se/pdf/73/733/07330053.pdf http://www.elfa.se/pdf/73/730/07307416.pdf http://www.elfa.se/pdf/73/730/07307432.pdf

Hi Chester, Welcome to this forum. I had a quick look at your site

You can get away with a simple ADC and a multiplexer circuit.

Dazza, This is a good overview to start from. I have been thinking about the variable voltage alternator, you can have some unwanted effects form a setup like that. It will be sensitive to which rpm it runs at since there is no battery for

Ffrige, If you don

Well, I don

Hi crisis, Welcome to this forum. Here is some info on fan control: http://www.cpemma.co.uk/pwm.html

Kain, If you want to save space try the Cool-Pak type resistor, just bolt it to the chassis.

Jin, Welcome to the forum. Here you can download six very nice books that cover electronics. http://www.ibiblio.org/obp/electricCircuits/ Good Luck!

Zwieke, The extra pins are there for a firm assembly only.
