'Circuit Cellar article'
Could anyone help me with a copy of the article in
Circuit Cellar, Design Forum with the article on
Design 98 with PIC's, video capture device.
I'm very interested in building a frame grabber,
but you need some high speed devices and I'd
like to see what they have to say about it.
The A to D chips do conversions at 30MHz. How to
heck do you buffer something at that speed?
Has anyone on this list tried to build something
like this before? I'd like to build one for composite

|I built one for a school project. If you would like to see the spec.s and
the results, go to http://www.geocities.com/ResearchTriangle/5256 and check
out the link to the Live Video Capture card. It worked quite well. The
resolution was only 100x100 but that could have been increased with a
larger memory buffer. If you want to do, color, that's where the high speed
digitizing is really necessary. Otherwise, all you need to do is detect the
synch pulses (there are IC's to do this), and digitize during the luminance
signal. Whatever you sample at during that pulse is your resolution. It's a
fun project! I'd be glad to help with any more specific questions you have.

I don't have subscriptions to alot ( any ) of magazines. I make up for it
at the library, sometimes I have another library fax me an article that
my branch does not subscribe to. They have also given me the option of
having them faxed to me.
Thanks for reading,
