You, sir, have one more subscriber.<BR/><BR/>@ kip -<BR/><BR/>Yeah, I'm trying to infer from the board layout. I just need more information about what those three inputs might be. I think it's safe to assume that the three outputs are red, green and blue in some order.<BR/><BR/>@ dennis -<BR/><BR/>I think I agree, though it seems weird. The circuit is effectively an RC oscillator, and thus isn't very stable. But, at the same time, the pixels need to be shifted out at a controlled rate. So, I can't figure out what role that oscillator would play in this circuit.Nick Johnsonhttp://www.blogger.com/profile/09742551843387605596noreply@blogger.comtag:blogger.com,1999:blog-6181310435977891397.post-43104985040442976832008-02-29T23:47:00.000-05:002008-02-29T23:47:00.000-05:002008-02-29T23:47:00.000-05:00The inverters connected together by a capacitor are almost certainly a primitive clock generator. Or (if there's no feedback) it could be to generate a time delay from one inverter to the next. But my bet is that it was just an easy way for them to make an oscillator because there were already extra inverters in the 7404 packages.Dennis Ferronhttp://www.blogger.com/profile/03601234553344631838noreply@blogger.comtag:blogger.com,1999:blog-6181310435977891397.post-18826559936687513342008-02-29T19:28:00.000-05:002008-02-29T19:28:00.000-05:002008-02-29T19:28:00.000-05:00I don't have any pointers either, but i just wanted to drop a line saying that i recently took apart a flatbed HP scanner and found one that looks exactly like that. the circuit board is slightly different but the CCD is in the exact same place.<BR/>My tip is look at the circuit board itself and make some inferences about the connections to it through the way it is connected to the board. on the back of mine i notice that a multitude are connected to a huge trace that is ground. i noticed that three sets are connected across the CCD<BR/>I havent thought of anything cool to do with mine yet, so you can have it if you want.k.i.p.http://www.blogger.com/profile/04863353116531245457noreply@blogger.comtag:blogger.com,1999:blog-6181310435977891397.post-62188021592573666532008-02-27T02:36:00.000-05:002008-02-27T02:36:00.000-05:002008-02-27T02:36:00.000-05:00Hi... this doesn't help you too much, I mostly wanted to say hi. I do happen to have stumbled on a CCD myself recently though, taking apart a digi cam. I also live in Brooklyn and am thinking about projects to do with it. You could have mine if you want though - you seem much more apt to finish your project. I don't know exactly what it is - from a CANON camera.<BR/>bunch of numbers on it... CK1-1056 might be the one...<BR/>email me I'll send you a picture of it.<BR/>kerryoco@gmail.com<BR/>like your blog a lot.<BR/>cheers<BR/>kerrykerryhttp://www.blogger.com/profile/15131992385794189061noreply@blogger.com
