DIY TV tuner

DragonMaster · 7th November 2004, 06:32 PM

Could someone design a DIY TV tuner? I want to listen to TV on PC monitor and only have a composite & s-video to VGA box. I'm doing electronics as an hobby and don't know how to design something.

Alps build some TV tuners, but I don't know what to do of the 4/5 pins other than ground, 5v, video out and audio out(Some have others than V and Aud out). I also wonder how they output stereo sound out of these things.

They also build some FM tuners with L-chan and R-chan audio outputs.

Actually, to get out stereo(dbx), I found NTE1800 IC

and there's a "dbx noise reduction" IC to go with this, which is the NTE1801.

How about just using a VCR as a tuner, and plugging the composite out on it into your vga box? You can probably get a VCR with a broken tape mechanism on trash day or at the dump

The only VCRs I know are either mono or shutting down because of a fault somewhere.

(Stupid self-diagnistics . . .)

I remember seeing several Stereo Toshibas on ebay, in scarbrough, ontario, fully functioning, with remote, and a buy it now for $25

I would want a tv tuner too but small enough to fit in the space left in the box i built for my sharp tft.

How about this? Its small, has a remote, and can be powered by 12 volts, so you can have one big powersupply for both a panel and fans and tuner. The price is right.

This box might be one of the crappy-unknown-china-company-thing-with-loose-plastic-and-tons-of-unuseful-features-with-a-poor-result
things you can get.

It´s also too big to fit in my screen case.

Just buy a tv-card for you computer. Most om them (make sure before you buy) also have s-video and composite in, so you can connect game consoles and vcrs to you computer and then send the image to the projector
