operating systems

Does anyone know of some other open source operating systems other than Ubuntu and Linux? because I'm getting quite pissed off at windows 2000. EDIT: there is some confusion about what I meant. I meant that Linux is the only OS that I know about. I didn't mean that I had ruled out Linux, I like Linux, I was just wondering about what other OS were out there.

Operation Immortality

Operation Immortality is a project to collect and archive the very best of what humanity is and has accomplished. On October 12, 2008, Richard Garriott, famed video game designer and the first second generation American astronaut, will take digitized DNA and human accomplishments with him to store in outer space when he journeys to the International Space Station.The archive will include information on humanity's greatest achievements, messages from people all over the world, and DNA samples from some of our brightest minds and most accomplished athletes. During the month of September, every human being is invited to come to the OperationImmortality.com website to submit their suggestions for our greatest achievements and leave a message for the cosmos. A lucky few may also be selected to add their DNA to the mix and join Richard Garriott as he rockets out of the atmosphere.With the LHC ready to do its thing, I think this organization has surfaced at the right time, save the earth, before we might all die.To def.LINK

operational amplifier

I need someone that can tell me what an operational amplifier is. ive been googling these shenanigans for the better part of a day and cant seem to find anything other than technical diagrams. i just want to know, generally, what they do, what theyre used for, and where i would find one inside something in my house. im actually really pissed off right now, every page ive read tells me how important they are, and exactly how they work, and that they are used "in a wide variety of electronics", and that they have "nearly infinite uses" but no one seems to say "hey, here's where you might be able to find one, and here's what it will be doing" anyone got any answers to this. and so help me god, if i see any schematics posted with that little triangle that ive been staring at all day, i might set someones house on fire.

Op amps? Which one is best?

I have a couple op amps collected over a couple years, and I am working on a design for a linear power supply, but have stability issues, and a "down to -V" common mode input voltage for op amps is a difficult parameter to find. Constraints: * Inputs must work down to as close to the negative supply rail as possible  * needs to be stable when used in a feedback loop for a linear power supply design * low noise / offset / blah blah good good goodies?? Hopefully? I'm actively testing these in a basic comparator circuit to see how far I can get the inputs to the -vee (or ground) before the op amp stops working as intended.I have tested the LM324, LM386, UA1458TC, LM741, and a few of the LT one's. Only the first 2 work well on a single supply w/ the inputs near ground or Vee LM324; // slow LM224; // ditto, but in weird thicc package LM386; // slow LM741; // ancient relics of the past, not rail to rail by any means, sucks IMO. UA1458TC // ancient relics of the past, not rail to rail by any means, sucks IMO. LM318H; // it's in a fancy metal case :D TL072CP; // JFET inputs, limited output current and the output can't go below the noninverting input. TL2072AC; // ditto. OP37; // These things aren't even that fast and can't work at unity gain. OP27; // ditto LT1007; LT1167; LT1191; LT1363; CRAZY fast, 1000V/uS!!! Maybe too fast... LT1360; LT1112;

I want to create a PS2 (slim) based fee paying game room for kids, but I want to make it coin operated. I want to use a MOSFET transister switch like this one http://brunningsoftware.co.uk/FET.htm which also doubles as a timer. The coin handling mechanism is the easy part, so dont bother about that.My problem is where to connect the MOSFETswitch in the PS2 console. My first idea was to connect one switch to each of the controllers ( to enable/ disable the controller's power supply on pin 5) but I understand the controller port is part of the PS2 motherboard and new electronic components cant be fitted there (true or false?). If true where else can I fix the switch in such a way that when a game is finished a new game cant be started without feeding in a coin?Any Ideas?

Operational Amplifier not working? Answered

Hello, I'm trying to use the KA324 IC (which consists of four opamps) for amplifying an audio signal. I've tried almost every schematic from this website: http://sound.westhost.com/dwopa.htm and also from lots of other websites, but none of them work. If the output volume is Really low, the sound is pretty good, but very quiet. When I turn up the volume, the sound is really bad, I almost can't recognise the song I'm playing. The output volume is also not that really high. If I keep increasing the input voltage, the output stops increasing after a while. It's not really 'loud' at that moment too. I've connected the IC to 12V DC (between the two middle pins). The + input goes to the ground connection, the - input goes to my POT voltage divider of the input voltage. The output pin goes straight to the speaker. I also added a 100kOhm resistor between output and - input. Without that resistor, I hear nothing at all but I think that's normal. I've also tried the three other op-amps from that IC but no luck. Is this opamp just not ment for audio amplification? or am I doing something wrong? Greetings, Electorials

Operational Amplifier input voltage affects other input?

Hello, I have created a simple circuit where 2 10k resistors make a voltage divider. Supply voltage is 12.5V and if I measure in between the 2 resistors, I'm getting 6.3V. Great! Now I connect that 6.3V to the +input of an OpAmp. Result: the value is still 6.3V. Great! (The OpAmp is also fed with 12.5V) Now I connect the -input of the OpAmp to the supply voltage (12.5V). The voltage in between both resistors suddenly changes from 6.3V to 10.1V. NOT Great! Now I connect the -input of the OpAmp to ground (0V). The voltage in between both resistors changes from 6.3V to 2.4V. ?! The output of the OpAmp is not connected to anything. I thought that OpAmp inputs, in theory, have infinite resistance? The datasheet of this OpAmp (LT1253) sais the input resistance should be 10Mohm I also tested this same thing with the LT1497 and the results are the same. When the -input of the  OpAmp was connected to 12.5V, I measured the current going into that pin, 39mA!! (Only measured on the LT1253) What's the problem here? Are both OpAmps broken? Or is there something about the way OpAmps work, that I clearly don't understand?

Need to operate a timer with a remote

I have a 6 Volt radio frequency remote control pair and a separate board with a 5 to 12 Volt timer circuit that turns power off to a load after 1 to 300 seconds. The timer circuit uses capacitors and resistors including a variable resistor plus a 555 too plus jumpers from Amazon.com to see a picture,it lists as: GEREE Timer Relay Switch 1-300 second 5V 9V 12v DC input TIME OVER RESET Delay. Will it work if I connect the RFRC to power and then from there wire to the timer and then wire the timer to my load so that I can remotely make the timer circuit  operate my load for the set time? I ask so as not to burn a thing that takes weeks to get. Will the 1 channel remote control receiver's single relay reset back into a NO condition from NC after current stops flowing from the battery power and through he remote control's 5 pin relay into the capacitor(s) of the timer circuit, that is to say, will the remote relay reset to NO after the timer's single relay goes back from NC to NO after the capacitor(s) run out of charge? As a note, I have had very little success finding a remote controlled timer in the 6 Volt range. 12 Volt remotes with timers are easier to find but that is too much power, size and expense for my application. Know of a supplier? If I have enough of this correct to make sense then any wisdom in this matter will be greatly appreciated. Thank you, Vince

Is a laser operated button pusher possible?

We have a business convention coming up soon. Inside of our display case we have this grid of LED panels. The goal of the display is you try and hit a button outside of the case when a certain LED panel is lit To demonstrate human vs. computing reflexes. I'd like to have some kind of external build to demonstrate with as the "vs.". I am thinking I can use a laser and point it at the LED block because lasers are capable of transferring data. I would think it wouldn't be too difficult to make a build that distinguishes between on & off. It's basic binary, on & off 1 & 0, true & false, same & changed. When the surface lights that the laser is pointed on, I think the easiest way to push the button would be to discharge a capacitor into a hobby motor, and some kind of tab or something on the motor. I can go into more detail on the build, but I need more info on making a laser operated trigger system thingy.

How to use an op-amp?

Hi, I've got an op-amp, the part number is OP07CP and I am trying to use it to amplify a voltage by around about 200 times. My set up is 6v going into a voltage divider with one resistor of 100ohm and a variable resistor of 10,000-50,000 ohm, so the output is 10mV-50mv. What I want to do is have the op-amp proportionally increase the voltage, so it goes to a voltage range of 1-5v, which an arduino can read. The power supply is  5v (from the arduino) and the powers both the voltage divider and the op-amp. For some reason, following the simple non-inverting op-amp configuration I just can't get it to work. Do I need a separate power source for the amp? I think it might have something to do with the fact that the amp's ground, input and negative are all just going to the arduino's ground. What can I do to fix it? If someone could help or even give me exact values and configurations of components that would be fantastic. I know that the amp and divider seem like a pointless complication if was just trying to measure the output of the variable resistor, but if you knew the greater extent of my project it would make more sense. Cheers
