I have tinkered a lot with 555 ic's for a while, and for the life of me, cannot find an understandable way to use transistors to replace the relays I am using with the 555's. Can anyone point me to a decent web page describing how to use transistors in my 555 application or in the paralell port device control project that this article is about?
Very high end mics (floor mics for stage productions, etc) use a 48 volt power source. Regular everyday microphones generate a small voltage by being moved by the sound wave that is being recording.
Holy crap, I read that book too. I read a bunch of books by that same author, all of the plot lines seem so strange now, but I guess at that age I was easily amused...
Ferrets. Ferrets instinctively know what you want left in tact, and then actively seek to destroy it. I had two of them who were allowed to run loose in my bedroom. Not only did they enjoy cords, they also developed a taste for mountain dew- they knew what the cans looked like, so if there was one on my desk, they would knock it over to get the dew to spill out, usually all over the monitor or keyboard. The last straw was when they toppled a sprite bottle onto the $2000 thinkpad... They now live in a cage that has 60 feet of drainage pipe hooked to it so they have room to run around.
I was sitting at work one night, sneaking in some slacking time. I was telnetted into the server at home, when a great idea stuck me. I remembered that I had left the volume setting of the amplifier connected to the server's sound card reasonably high, so I did a search for 'satan.wav', something that would freak out my roommate. The computer I was on didn't have a sound card, so I wasn't able to play the sound before I ftp'd it to the server and ran 'sox satan.wav.' I waited a few minutes and typed it again, then again a bit later.
I got home, and the roommate was still awake. I told him he looked a little pale, was everything alright? He said everything was fine, but gave me a funny look. I sat down and played the sound while laughing at him and he went nuts. I guess he had been sleeping- the sound woke him up. As he was falling back asleep he heard it the second time I played it. He wasn't able to go back to sleep because he thought he was loosing it. The sound clip was "Hi, this is satan, I hope you enjoy the show." I laughed my ass off at him, and he got over being pissed an hour later. Still one of the best pranks I've ever played.
I understand that to mean I can't listen in to police communications to avoid getting caught doing something, but its perfectly legal to listen for entertainment.
The power went out a few weeks ago, and after waiting for hours for it to come back on, I decided to just give up and get some sleep. I had to work in the morning.
Sleep did not come, however. I found that it was WAY too quiet in the room without the computers whirring and crunching. Although a quiet PC is nice, shouldn't all geeks pretty much be used to the constant noise, like people whose yards back up to a major highway?
The FCC, the government organization that deals with radio transmissions, gives us the same right you have, that it shall not be made illegal to recieve a radio transmission. That will probably just get stomped on and ignored, the new laws will stand for 3 or 4 years until someone gets charged with violating it, appeals all the way to a court high enough to have some authority, then the law will be overturned. Theres no planning ahead or common sense among the people who make the laws.
I used to play battletech in pods at a club I used to go to. The way it was set up, the coolness factor didn't really come from the virtual aspect, but from it being so much easier having actual buttons to push rather than trying to remember what letter on the keyboard to push to perform the function you needed.
I have some amplified speakers hooked up to my reciever in my living room. The speakers take XLR input, while the reviever outputs to regular speaker wire. After hacking up the XLR cables, I noticed that I got the same effect as you had. I could very audibly hear sound coming through the speakers when they were powered but had no input. I believe it was the God channel, but I'm not sure. For some reason, I can recieve the God channel on TV even when there's no antenna input plugged in, so either the transmitter is very close to me, or Jesus is trying to tell me someting.
Using unhacked XLR cable with a very short length of speaker wire fixed the problem. I was using a long length of speaker wire and a short length of XLR when I was having the problem. Shielding was the problem, it would seem.
I did a half assed thing like this for my brother. Just go to any shareware site and search for "guitar." If I remember correctly, one of the programs I set him up with was called stompbox; probably for windows, but maybe for linux. It allows you to string together virtual stompboxes to get almost any effect you could think of. The latency was managable on his 500mhZ compaq, and it was convenient playing through the pc speakers. Most programs like this allow you to add percusion easily.
Around here, payphones at $.35 weren't making money. The biggest cost was looking up where the phone you were calling was located, so they knew if it was long distance or not. To fix this, the phone company jacked up the price to $.50 to cover the lookup cost, but then gave you unlimited minutes. When I worked security, some sites required you to sit in your car all night. I brought my laptop and acoustic coupler, was able to surf for usually 45 mins at a time before something disrupted the coupler or I lost the connection for some other reason. $.50 for 45 mins was not a bad deal at all.
Up until a few months ago, I worked as a section 8 housing cop, and NO ONE in the ghetto uses pay phones. Most folks will wander for half an hour begging to use someone's phone who has one rather than stick the 50 cents in one of the many conveniently located pay phones. Whenever there was a problem on the property, magically 50% of the residents knew about it in less than 2 minutes, and a few would invariably come find us. We wandered the 4 buildings the whole night, and were never hard to find.
As for people without a phone that don't live in apartments, im sure it works the same way; they go to a neighbor's, or in case of emergency, the neighbor who hopefully has a phone will hear the screaming.
I'd much have prefered radiation be stinky, at least then I'd know i was in trouble. Kinda along the same lines of them putting an artificial smell in natural gas.
I worked security at a department of energy lab for about a year. There were a few radioactive zones in, near, and around the particle accelerator, and all were well marked, but there were certain spots where I definately would have felt better if I had something that could tell me the radiation level in the area. Security was always first on the scene in case of fire or accident, and you never knew just what could have been destroyed to the point of allowing radiation to leak out. Radiation wise, nothing real bad ever happened, but that was the scariest part of working there sometimes, the radiation that you can't see, smell, or feel.
BTW, they'd probably post the price because it is interesting and good to know. If you don't have $1100 lying around, why bother clicking through to see how much the price is?

You don't need a new light, its just fine. Replace the buld with the same type. What you need to do is to replace your clumsy wife.

Sony Vaio GT3/K: You Spilled Your Laptop on my Camcorder
Posted by CmdrTaco on Wednesday April 30, @10:55PM from the you-spilled-camcorder-on-my-laptop dept.
Must have been way too busy racking thier brain trying to think of a witty department...
Save money, stick a thermistor in your joystick port, one end in pin 1, the other in pin 3. ~10 lines of perl to monitor temp.
Then you'd cut at an angle.
Holy crap, I read that book too. I read a bunch of books by that same author, all of the plot lines seem so strange now, but I guess at that age I was easily amused...

You are exactly right. We will try ANYTHING to avoid having to do exersize. The bottom line is that there are really only 2 ways to loose weight-
1)Take in less calories
2)Burn more calories
The best is a combination of the two. This is a basic fact, and there is no way around it, I don't care what Oprah magazine says.

It sounds that that children's book, see spot run. Say it out loud.

Just out of curiosity, if you had to guess, what percentage of cases did you approve to go to trial?
