    How do I draw a truth table for this!???!

    I know he said truth table. What this whole thing is supposed to do is create the illusion of random lights turning on and off. So, he said to make a truth table to see how random it actually is...... So, maybe he meant "timing diagram", but I don't know what that is...

    How do I draw a truth table for this!???!

    My teacher said I should make a truth table for this (Not as an assignment) but I have no idea how to make a truth table for this circuit. Could someone give me a template or tell me how I could do it? Thanks! -------------------------------------------- I figure one of these will work for...

    Clocks - Integrated?

    If, you don't know about ASCII binary, don't worrie about, it's really not needed at this point. All I need is a clock... Thanks :)

    Clocks - Integrated?

    Im doing a project, and it's really sorta small, ... its a 4" cube..... I'm trying to build a binary clock for it. current time - for me anyways   O o O o o O o o O owhere "O" is on and "o" is off. Does anyone have any ideas for this? It is running off of a small voltage probably 5 volts...

    Where can I buy Black Perf Board

    Any one know where I can purchase black perf board? I will probably need something around 160 square inches. Thanks,     Infinite Mind.

    Electronic latching circuit?

    Is there such a thing as an "electronic latching circuit"? Like what is used in motor controll where a relay will power its self once a button is pressed... Mainy I was just wondering if that is possible, and if possible a diagrame...? Thanks!

    Random LEDs, random time on/off?

    Ah, fast on off. Me and my teacher came up with the idea of using a bunch of N555 timers with different frequencies. Each timer will control 2 LEDs. So when the signal is positive, the one LED is on and when the signal is negative, another LED is on. Using different frequencies allows for random...

    Random LEDs, random time on/off?

    Do you have any information on these chips? I never used them, I'm affraid the only chip I've used was a N555 timer.

    ohms testing

    Why does it have to be an LCD? Why not something simpler? In order to read the resistance you need two wires, if you only have 5 wires...!??? Why not just buy a 100 $5 ohmmeters? Why not look for schematics on line? You might want to buy a simply ohmmeter, rip it apart, throw it a way, buy a...

    Random LEDs, random time on/off?

    Wow, No ideas? How about we start small? How do I create a circut that can select a random LED? There, that should be easier to answer... Thanks!

    Random LEDs, random time on/off?

    I have 64 LEDs aligned in an 8 by 8 square, I want to create a circut that will choose a random number of LEDs, random LEDs, and a random length of time off/on. Basiclly, it's a random light show. I don't have room to play with either, so it's quite difficult. Any one know a good way to do...
