I'm trying to dig up information on the CMOS sensor. This is what i have so far: -- http://forums.quickcamteam.net/showthread.php?tid=265 The QuickCam Pro 9000 has a CMOS-sensor with a resolution of 1600x1200 and its size is 6mm x 4mm (I meassured it). [trying to confirm this persons...

Ok so this really has nothing to do with astronomy, besides the use of lens,... but it is a lens question so here goes :P (moderators may move this if their's a more appropriate place for it) Information printed on the lens: "Carl Zeiss Tessar 2.0/3.7 2MP Autofocus". This is from a...

thx :P

hmm the only possibilities i can think of is the cmos somehow getting stuck with both transistors in a partially on state. Another thing is maybe the gate acts as an antenna causing odd switching :P

Ya that SPDT switch would be great. I'll see if the parts guy has it. debouncing wasn't an issue because we were clocking manually by hand so their was plenty of time for steady state. I wonder if an inverter would consider a floating pin as a logic "0" input. If so then the following...

Problem Solved. Ok the SIL resistor pack was the one where all the resistors were connected to a common wire... which made it really easy to wire the leds :P Also the problem with the odd d-flip-flop behavior is... that theirs a difference between using a switch (like the lab manual...

Hi if your dealing with thevenin and norton circuits then i suggest you memorize the effects on wire that is short circuited (if i remember right, voltage and resistance = 0, and i = unknown), and on open circuited (if i remember right, i = 0, voltage and resistance = unknown). This can be...

kk. i won't be able to find out until next week lol

yes that is a led thing. the pin spacing matches protoboard squares if that's the question. and its not the led thing but the red thing that i was confused about.

Ok first thanks everyone for info about those inline resistors. Now onto the reply. The labmanual (http://coefs2.njit.edu/ECE394/ECE394-V.htm ) says their TTL D-flip-flops 7474 on the bottom and has this link: http://coefs2.njit.edu/main/datas/74hc74.pdf It says somewhere in the specs tests...

In my lab we're doing some stuff with logic chips and d-flip-flops and in our kit of circuit components are a couple of these red plastic covered strips that have about 12 pins coming out. Their some kind of resistor strip but question is how do you use them? do you just consider each 2 pins...

Hi, In my lab manual it says i need to: "adjust the wave generator's frequency... The frequency of normal operation for the UART is 25Mkz" So is this a type for mega-hertz or some weird shorthand for mega-kilo-hertz :P

OK apparently theirs two or more forms: xy + x'z + yz = xy + x'z found this one in a book, and matched wikipedia.

Nvm i found it in the solutions for that homework. It's called the "consensus theorem" where: xy' + xz' +y'z =xz' + y'z Had a feeling it was some obscure identity/law lol

Hi, This is a question about a boolean "law" type behavior I've noticed in my homework a couple of times. Basically i can't find a boolean algebra law that permits this optimization short of using a k-map. So I'm just wondering if theirs some way to optimize the one equation using...
